Executive Summary of Clinical Practice Guideline on Immunotherapy for Inhalant Allergy.

OBJECTIVE: Allergen immunotherapy (AIT) is the therapeutic exposure to an allergen or allergens selected by clinical assessment and allergy testing to decrease allergic symptoms and induce immunologic tolerance. Inhalant AIT is administered to millions of patients for allergic rhinitis (AR) and allergic asthma (AA) and is most commonly delivered as subcutaneous immunotherapy (SCIT) or sublingual immunotherapy (SLIT). Despite its widespread use, there is variability in the initiation and delivery of safe and effective immunotherapy, and there are opportunities for evidence-based recommendations for improved patient care. PURPOSE: The purpose of this clinical practice guideline is to identify quality improvement opportunities and provide clinicians trustworthy, evidence-based recommendations regarding the management of inhaled allergies with immunotherapy. Specific goals of the guideline are to optimize patient care, promote safe and effective therapy, reduce unjustified variations in care, and reduce risk of harm. The target patients for the guideline are any individuals aged 5 years and older with AR, with or without AA, who are either candidates for immunotherapy or treated with immunotherapy for their inhalant allergies. The target audience is all clinicians involved in the administration of immunotherapy. This guideline is intended to focus on evidence-based quality improvement opportunities judged most important by the guideline development group. It is not intended to be a comprehensive, general guide regarding the management of inhaled allergies with immunotherapy. The statements in this guideline are not intended to limit or restrict care provided by clinicians based on their experience and assessment of individual patients. ACTION STATEMENTS: The guideline development group made a strong recommendation that (Key Action Statement [KAS] 10) the clinician performing allergy skin testing or administering AIT must be able to diagnose and manage anaphylaxis. The guideline development group made recommendations for the following KASs: (KAS 1) Clinicians should offer or refer to a clinician who can offer immunotherapy for patients with AR with or without AA if their patients' symptoms are inadequately controlled with medical therapy, allergen avoidance, or both, or have a preference for immunomodulation. (KAS 2A) Clinicians should not initiate AIT for patients who are pregnant, have uncontrolled asthma, or are unable to tolerate injectable epinephrine. (KAS 3) Clinicians should evaluate the patient or refer the patient to a clinician who can evaluate for signs and symptoms of asthma before initiating AIT and for signs and symptoms of uncontrolled asthma before administering subsequent AIT. (KAS 4) Clinicians should educate patients who are immunotherapy candidates regarding the differences between SCIT and SLIT (aqueous and tablet) including risks, benefits, convenience, and costs. (KAS 5) Clinicians should educate patients about the potential benefits of AIT in (1) preventing new allergen sensitization, (2) reducing the risk of developing AA, and (3) altering the natural history of the disease with continued benefit after discontinuation of therapy. (KAS 6) Clinicians who administer SLIT to patients with seasonal AR should offer pre- and co-seasonal immunotherapy. (KAS 7) Clinicians prescribing AIT should limit treatment to only those clinically relevant allergens that correlate with the patient's history and are confirmed by testing. (KAS 9) Clinicians administering AIT should continue escalation or maintenance dosing when patients have local reactions to AIT. (KAS 11) Clinicians should avoid repeat allergy testing as an assessment of the efficacy of ongoing AIT unless there is a change in environmental exposures or a loss of control of symptoms. (KAS 12) For patients who are experiencing symptomatic control from AIT, clinicians should treat for a minimum duration of 3 years, with ongoing treatment duration based on patient response to treatment. The guideline development group offered the following KASs as options: (KAS 2B) Clinicians may choose not to initiate AIT for patients who use concomitant beta-blockers, have a history of anaphylaxis, have systemic immunosuppression, or have eosinophilic esophagitis (SLIT only). (KAS 8) Clinicians may treat polysensitized patients with a limited number of allergens.

Specific goals of the guideline are to optimize patient care, promote safe and effective therapy, reduce unjustified variations in care, and reduce the risk of harm. The target patients for the guideline are any individuals aged 5 years and older with AR, with or without AA, who are either candidates for immunotherapy or treated with immunotherapy for their inhalant allergies. The target audience is all clinicians involved in the administration of immunotherapy. This guideline is intended to focus on evidence-based quality improvement opportunities judged most important by the guideline development group (GDG). It is not intended to be a comprehensive, general guide regarding the management of inhaled allergies with immunotherapy. The statements in this guideline are not intended to limit or restrict care provided by clinicians based on their experience and assessment of individual patients.

Utility of two-stage laryngotracheal reconstruction in the management of subglottic stenosis in adults.

OBJECTIVES: We examined a retrospective case series to evaluate the utility of two-stage laryngotracheal reconstruction (LTR) in the management of subglottic stenosis (SGS) in adults. Operative correction of SGS with LTR has been practiced successfully in the pediatric population. However, in the adult population, cricotracheal resection has been a more common alternative. METHODS: We reviewed the medical records at the Wayne State University Department of Otolaryngology-Head and Neck Surgery. We included all adult patients with SGS who underwent LTR and completed the recommended procedures between December 24, 2003, and October 1,2010. RESULTS: Twelve of the 14 patients identified were decannulated (86%). Of the 12 decannulated patients, 1 required a salvage operation, eventually achieving decannulation after cricotracheal resection. Therefore, although our overall decannulation rate was 86%, the rate with LTR alone was 79%. The majority of our patients (71%) had high-grade (grade III or IV) stenosis. CONCLUSIONS: We conclude that LTR is a viable option for adult patients with SGS. In children, LTR is a relatively safe and often-performed procedure. With use of modern techniques, it has the potential to be applicable to adults, as well. It has the added benefit of avoiding the pitfalls and complications associated with cricotracheal resection.

Congenital Pharyngeal Web in an Adult: Treatment of a Rare Clinical Anomaly by Coblation.

INTRODUCTION TO THE TOPIC: Previous reports of congenital pharyngeal webs, although rare, have been described in children. Clinical presentation varies, ranging from aspiration to intermittent airway obstruction, and most commonly, dysphagia. In this case report, the authors describe an unusual finding of a hypopharyngeal web in an adult patient. This patient had no prior history of chemoradiotherapy, malignancy, or total laryngectomy, all of which have been associated with acquired pharyngeal stenosis, supporting that this finding was of congenital origin. After a review of the possible embryological developmental abnormalities, the hypothesis is that of gut recanalization failure during development. CASE PRESENTATION: We present a case of a woman in her mid-40's with a history of solid food dysphagia resulting in a 20 kg weight loss over three months. The patient denied dysphagia progressing to liquids, pain with swallowing, and a history of alcohol or tobacco use. Upon examination of the larynx via laryngoscope, a congenital hypopharyngeal web was identified. Successful excision of the web via coblation restored proper drainage of the pyriform sinus into the esophagus and resulted in markedly improved swallowing function and weight gain. CONCLUSIONS: Pharyngeal webs are rare findings, particularly in adult patients. These congenital anomalies can be safely and effectively treated endoscopically via coblation.

Conservative management of iatrogenic esophageal perforation in head and neck cancer patients with esophageal stricture.

OBJECTIVE: Evaluate the efficacy of conservative management of iatrogenic esophageal perforation following dilatation of a stricture secondary to the treatment of head and neck cancer. STUDY DESIGN: Case series with chart review. SUBJECTS AND METHODS: Retrospective chart review of 24 patients with esophageal perforation treated at the Detroit Medical Center from 1999 to 2008. Of these, eight head and neck cancer patients had esophageal stricture and underwent dilatation with subsequent esophageal perforation. RESULTS: Six patients were managed conservatively; two were managed surgically. All eight patients had radiation, six had chemotherapy, and five had surgery as part of their oncologic treatment. Stricture site was at the cricopharyngeus or neopharynx. Perforation size was estimated at 3 to 7 mm in conservative patients and approximately 10 mm in surgical patients. All patients survived to be discharged from the hospital and diet was tube feeds. CONCLUSION: In head and neck cancer patients with post-treatment esophageal stricture, iatrogenic cervical esophageal perforations can often be safely managed conservatively. The criteria are: prompt diagnosis within one hour, small perforation (3-7 mm), penetrating type of perforation with circumferential mucosal contact, proximal or cervical esophageal location, and stabilization and improvement of clinical signs and symptoms for 24 hours after initial ICU management.

Craniocervical necrotizing fasciitis with and without thoracic extension: management strategies and outcome.

OBJECTIVE: First objective was to review cases of craniocervical necrotizing fasciitis (CCNF) at Wayne State University/Detroit Medical Center (Detroit, MI) for the last 18 years. Second was to analyze patients with and without thoracic extension for contributing factors. METHODS: Retrospective review of 660 patients with necrotizing fasciitis treated at WSU/DMC from January 1989 to January 2007 was conducted. Data regarding source/extent of infection, presenting signs/symptoms, computed tomography, microbiology, antibiotics, comorbidities, number/type of operations, hyperbaric oxygen (HBO) therapy, hospital duration, complications, and overall outcome were compared/analyzed between patients with and without thoracic extension. RESULTS: Twenty patients with CCNF for the past 18 years met the inclusion criteria. Ten patients had thoracic extension, and 10 patients did not have. Individuals in the thoracic extension group were likely to be older, had increased comorbidity, required more surgical debridement, experienced increased postoperative complications, and had lower overall survival. Three patients with thoracic extension underwent HBO therapy and 66% survived. CONCLUSION: This is the largest single institutional review of CCNF comparing patients with and without thoracic extension. Patients with thoracic extension have a poorer outcome as follows: 60% (6/10) survival vs 100% (10/10) for those without thoracic extension (P < .05). The CCNF patients without thoracic extension treated at our institution all survived after prompt medical and surgical intervention. Overall survival of CCNF patients without thoracic extension may be attributed to rigorous wound care, broad spectrum intravenous antibiotics, aggressive surgical debridement, and vigilant care in surgical intensive care unit. The HBO therapy should be included if the patient can tolerate it.

Clinical Practice Guideline: Sudden Hearing Loss (Update).

OBJECTIVE: Sudden hearing loss is a frightening symptom that often prompts an urgent or emergent visit to a health care provider. It is frequently but not universally accompanied by tinnitus and/or vertigo. Sudden sensorineural hearing loss affects 5 to 27 per 100,000 people annually, with about 66,000 new cases per year in the United States. This guideline update provides evidence-based recommendations for the diagnosis, management, and follow-up of patients who present with sudden hearing loss. It focuses on sudden sensorineural hearing loss in adult patients aged ≥18 years and primarily on those with idiopathic sudden sensorineural hearing loss. Prompt recognition and management of sudden sensorineural hearing loss may improve hearing recovery and patient quality of life. The guideline update is intended for all clinicians who diagnose or manage adult patients who present with sudden hearing loss. PURPOSE: The purpose of this guideline update is to provide clinicians with evidence-based recommendations in evaluating patients with sudden hearing loss and sudden sensorineural hearing loss, with particular emphasis on managing idiopathic sudden sensorineural hearing loss. The guideline update group recognized that patients enter the health care system with sudden hearing loss as a nonspecific primary complaint. Therefore, the initial recommendations of this guideline update address distinguishing sensorineural hearing loss from conductive hearing loss at the time of presentation with hearing loss. They also clarify the need to identify rare, nonidiopathic sudden sensorineural hearing loss to help separate those patients from those with idiopathic sudden sensorineural hearing loss, who are the target population for the therapeutic interventions that make up the bulk of the guideline update. By focusing on opportunities for quality improvement, this guideline should improve diagnostic accuracy, facilitate prompt intervention, decrease variations in management, reduce unnecessary tests and imaging procedures, and improve hearing and rehabilitative outcomes for affected patients. METHODS: Consistent with the American Academy of Otolaryngology-Head and Neck Surgery Foundation's "Clinical Practice Guideline Development Manual, Third Edition" (Rosenfeld et al. Otolaryngol Head Neck Surg. 2013;148[1]:S1-S55), the guideline update group was convened with representation from the disciplines of otolaryngology-head and neck surgery, otology, neurotology, family medicine, audiology, emergency medicine, neurology, radiology, advanced practice nursing, and consumer advocacy. A systematic review of the literature was performed, and the prior clinical practice guideline on sudden hearing loss was reviewed in detail. Key Action Statements (KASs) were updated with new literature, and evidence profiles were brought up to the current standard. Research needs identified in the original clinical practice guideline and data addressing them were reviewed. Current research needs were identified and delineated. RESULTS: The guideline update group made strong recommendations for the following: (KAS 1) Clinicians should distinguish sensorineural hearing loss from conductive hearing loss when a patient first presents with sudden hearing loss. (KAS 7) Clinicians should educate patients with sudden sensorineural hearing loss about the natural history of the condition, the benefits and risks of medical interventions, and the limitations of existing evidence regarding efficacy. (KAS 13) Clinicians should counsel patients with sudden sensorineural hearing loss who have residual hearing loss and/or tinnitus about the possible benefits of audiologic rehabilitation and other supportive measures. These strong recommendations were modified from the initial clinical practice guideline for clarity and timing of intervention. The guideline update group made strong recommendations against the following: (KAS 3) Clinicians should not order routine computed tomography of the head in the initial evaluation of a patient with presumptive sudden sensorineural hearing loss. (KAS 5) Clinicians should not obtain routine laboratory tests in patients with sudden sensorineural hearing loss. (KAS 11) Clinicians should not routinely prescribe antivirals, thrombolytics, vasodilators, or vasoactive substances to patients with sudden sensorineural hearing loss. The guideline update group made recommendations for the following: (KAS 2) Clinicians should assess patients with presumptive sudden sensorineural hearing loss through history and physical examination for bilateral sudden hearing loss, recurrent episodes of sudden hearing loss, and/or focal neurologic findings. (KAS 4) In patients with sudden hearing loss, clinicians should obtain, or refer to a clinician who can obtain, audiometry as soon as possible (within 14 days of symptom onset) to confirm the diagnosis of sudden sensorineural hearing loss. (KAS 6) Clinicians should evaluate patients with sudden sensorineural hearing loss for retrocochlear pathology by obtaining magnetic resonance imaging or auditory brainstem response. (KAS 10) Clinicians should offer, or refer to a clinician who can offer, intratympanic steroid therapy when patients have incomplete recovery from sudden sensorineural hearing loss 2 to 6 weeks after onset of symptoms. (KAS 12) Clinicians should obtain follow-up audiometric evaluation for patients with sudden sensorineural hearing loss at the conclusion of treatment and within 6 months of completion of treatment. These recommendations were clarified in terms of timing of intervention and audiometry and method of retrocochlear workup. The guideline update group offered the following KASs as options: (KAS 8) Clinicians may offer corticosteroids as initial therapy to patients with sudden sensorineural hearing loss within 2 weeks of symptom onset. (KAS 9a) Clinicians may offer, or refer to a clinician who can offer, hyperbaric oxygen therapy combined with steroid therapy within 2 weeks of onset of sudden sensorineural hearing loss. (KAS 9b) Clinicians may offer, or refer to a clinician who can offer, hyperbaric oxygen therapy combined with steroid therapy as salvage therapy within 1 month of onset of sudden sensorineural hearing loss. DIFFERENCES FROM PRIOR GUIDELINE: Incorporation of new evidence profiles to include quality improvement opportunities, confidence in the evidence, and differences of opinion Included 10 clinical practice guidelines, 29 new systematic reviews, and 36 new randomized controlled trials Highlights the urgency of evaluation and initiation of treatment, if treatment is offered, by emphasizing the time from symptom occurrence Clarification of terminology by changing potentially unclear statements; use of the term sudden sensorineural hearing loss to mean idiopathic sudden sensorineural hearing loss to emphasize that >90% of sudden sensorineural hearing loss is idiopathic sudden sensorineural hearing loss and to avoid confusion in nomenclature for the reader Changes to the KASs from the original guideline: KAS 1-When a patient first presents with sudden hearing loss, conductive hearing loss should be distinguished from sensorineural. KAS 2-The utility of history and physical examination when assessing for modifying factors is emphasized. KAS 3-The word "routine" is added to clarify that this statement addresses nontargeted head computerized tomography scan that is often ordered in the emergency room setting for patients presenting with sudden hearing loss. It does not refer to targeted scans, such as temporal bone computerized tomography scan, to assess for temporal bone pathology. KAS 4-The importance of audiometric confirmation of hearing status as soon as possible and within 14 days of symptom onset is emphasized. KAS 5-New studies were added to confirm the lack of benefit of nontargeted laboratory testing in sudden sensorineural hearing loss. KAS 6-Audiometric follow-up is excluded as a reasonable workup for retrocochlear pathology. Magnetic resonance imaging, computerized tomography scan if magnetic resonance imaging cannot be done, and, secondarily, auditory brainstem response evaluation are the modalities recommended. A time frame for such testing is not specified, nor is it specified which clinician should be ordering this workup; however, it is implied that it would be the general or subspecialty otolaryngologist. KAS 7-The importance of shared decision making is highlighted, and salient points are emphasized. KAS 8-The option for corticosteroid intervention within 2 weeks of symptom onset is emphasized. KAS 9-Changed to KAS 9A and 9B. Hyperbaric oxygen therapy remains an option but only when combined with steroid therapy for either initial treatment (9A) or salvage therapy (9B). The timing of initial therapy is within 2 weeks of onset, and that of salvage therapy is within 1 month of onset of sudden sensorineural hearing loss. KAS 10-Intratympanic steroid therapy for salvage is recommended within 2 to 6 weeks following onset of sudden sensorineural hearing loss. The time to treatment is defined and emphasized. KAS 11-Antioxidants were removed from the list of interventions that the clinical practice guideline recommends against using. KAS 12-Follow-up audiometry at conclusion of treatment and also within 6 months posttreatment is added. KAS 13-This statement on audiologic rehabilitation includes patients who have residual hearing loss and/or tinnitus who may benefit from treatment. Addition of an algorithm outlining KASs Enhanced emphasis on patient education and shared decision making with tools provided to assist in same.

Baseline laryngeal effects among individuals with dust mite allergy.

OBJECTIVE: To examine baseline effects of perennial allergy on laryngeal appearance, laryngeal function, and perceived vocal handicap among individuals without current allergy or voice symptoms. DATA SOURCES: This pilot study included 47 adults: 21 with positive and 26 with negative skin test responses for the dust mite, Dermatophagoides pteronyssinus. METHODS: Subjects were tested for sensitivity to dust mite antigen by prick testing. Laryngeal appearance and function were studied with laryngovideostroboscopy, acoustic and speech aerodynamic analysis, and voice sampling. These parameters were blindly analyzed by three trained examiners. Subjects also completed the Voice Handicap Index (VHI) as a measure of vocal handicap. RESULTS: Subjects allergic to dust mites perceived significantly greater vocal handicap on the VHI than did nonallergic subjects. No significant differences were noted between groups in laryngeal appearance or function. CONCLUSION: These pilot data suggest that, at baseline, allergic individuals perceive greater vocal handicap than their nonallergic counterparts (P = 0.04), even in the absence of current allergy symptoms or observable physical or functional abnormalities. These preliminary observations can serve as an impetus for further research into this important area, including the potential interrelationship between acid reflux disease and allergic laryngeal inflammation.

Plain Language Summary: Hoarseness (Dysphonia).

This plain language summary for patients serves as an overview in explaining hoarseness (dysphonia). The summary applies to patients in all age groups and is based on the 2018 "Clinical Practice Guideline: Hoarseness (Dysphonia) (Update)." The evidence-based guideline includes research to support more effective identification and management of patients with hoarseness (dysphonia). The primary purpose of the guideline is to improve the quality of care for patients with hoarseness (dysphonia) based on current best evidence.

Clinical Practice Guideline: Hoarseness (Dysphonia) (Update) Executive Summary.

Objective This guideline provides evidence-based recommendations on treating patients presenting with dysphonia, which is characterized by altered vocal quality, pitch, loudness, or vocal effort that impairs communication and/or quality of life. Dysphonia affects nearly one-third of the population at some point in its life. This guideline applies to all age groups evaluated in a setting where dysphonia would be identified or managed. It is intended for all clinicians who are likely to diagnose and treat patients with dysphonia. Purpose The primary purpose of this guideline is to improve the quality of care for patients with dysphonia, based on current best evidence. Expert consensus to fill evidence gaps, when used, is explicitly stated and supported with a detailed evidence profile for transparency. Specific objectives of the guideline are to reduce inappropriate variations in care, produce optimal health outcomes, and minimize harm. For this guideline update, the American Academy of Otolaryngology-Head and Neck Surgery Foundation selected a panel representing the fields of advanced practice nursing, bronchoesophagology, consumer advocacy, family medicine, geriatric medicine, internal medicine, laryngology, neurology, otolaryngology-head and neck surgery, pediatrics, professional voice, pulmonology, and speech-language pathology. Action Statements The guideline update group made strong recommendations for the following key action statements (KASs): (1) Clinicians should assess the patient with dysphonia by history and physical examination to identify factors where expedited laryngeal evaluation is indicated. These include but are not limited to recent surgical procedures involving the head, neck, or chest; recent endotracheal intubation; presence of concomitant neck mass; respiratory distress or stridor; history of tobacco abuse; and whether the patient is a professional voice user. (2) Clinicians should advocate voice therapy for patients with dysphonia from a cause amenable to voice therapy. The guideline update group made recommendations for the following KASs: (1) Clinicians should identify dysphonia in a patient with altered voice quality, pitch, loudness, or vocal effort that impairs communication or reduces quality of life (QOL). (2) Clinicians should assess the patient with dysphonia by history and physical examination for underlying causes of dysphonia and factors that modify management. (3) Clinicians should perform laryngoscopy, or refer to a clinician who can perform laryngoscopy, when dysphonia fails to resolve or improve within 4 weeks or irrespective of duration if a serious underlying cause is suspected. (4) Clinicians should perform diagnostic laryngoscopy, or refer to a clinician who can perform diagnostic laryngoscopy, before prescribing voice therapy and document/communicate the results to the speech-language pathologist (SLP). (5) Clinicians should advocate for surgery as a therapeutic option for patients with dysphonia with conditions amenable to surgical intervention, such as suspected malignancy, symptomatic benign vocal fold lesions that do not respond to conservative management, or glottic insufficiency. (6) Clinicians should offer, or refer to a clinician who can offer, botulinum toxin injections for the treatment of dysphonia caused by spasmodic dysphonia and other types of laryngeal dystonia.

Clinical Practice Guideline: Hoarseness (Dysphonia) (Update).

Objective This guideline provides evidence-based recommendations on treating patients who present with dysphonia, which is characterized by altered vocal quality, pitch, loudness, or vocal effort that impairs communication and/or quality of life. Dysphonia affects nearly one-third of the population at some point in its life. This guideline applies to all age groups evaluated in a setting where dysphonia would be identified or managed. It is intended for all clinicians who are likely to diagnose and treat patients with dysphonia. Purpose The primary purpose of this guideline is to improve the quality of care for patients with dysphonia, based on current best evidence. Expert consensus to fill evidence gaps, when used, is explicitly stated and supported with a detailed evidence profile for transparency. Specific objectives of the guideline are to reduce inappropriate variations in care, produce optimal health outcomes, and minimize harm. For this guideline update, the American Academy of Otolaryngology-Head and Neck Surgery Foundation selected a panel representing the fields of advanced practice nursing, bronchoesophagology, consumer advocacy, family medicine, geriatric medicine, internal medicine, laryngology, neurology, otolaryngology-head and neck surgery, pediatrics, professional voice, pulmonology, and speech-language pathology. Action Statements The guideline update group made strong recommendations for the following key action statements (KASs): (1) Clinicians should assess the patient with dysphonia by history and physical examination to identify factors where expedited laryngeal evaluation is indicated. These include, but are not limited to, recent surgical procedures involving the head, neck, or chest; recent endotracheal intubation; presence of concomitant neck mass; respiratory distress or stridor; history of tobacco abuse; and whether the patient is a professional voice user. (2) Clinicians should advocate voice therapy for patients with dysphonia from a cause amenable to voice therapy. The guideline update group made recommendations for the following KASs: (1) Clinicians should identify dysphonia in a patient with altered voice quality, pitch, loudness, or vocal effort that impairs communication or reduces quality of life (QOL). (2) Clinicians should assess the patient with dysphonia by history and physical examination for underlying causes of dysphonia and factors that modify management. (3) Clinicians should perform laryngoscopy, or refer to a clinician who can perform laryngoscopy, when dysphonia fails to resolve or improve within 4 weeks or irrespective of duration if a serious underlying cause is suspected. (4) Clinicians should perform diagnostic laryngoscopy, or refer to a clinician who can perform diagnostic laryngoscopy, before prescribing voice therapy and document/communicate the results to the speech-language pathologist (SLP). (5) Clinicians should advocate for surgery as a therapeutic option for patients with dysphonia with conditions amenable to surgical intervention, such as suspected malignancy, symptomatic benign vocal fold lesions that do not respond to conservative management, or glottic insufficiency. (6) Clinicians should offer, or refer to a clinician who can offer, botulinum toxin injections for the treatment of dysphonia caused by spasmodic dysphonia and other types of laryngeal dystonia. (7) Clinicians should inform patients with dysphonia about control/preventive measures. (8) Clinicians should document resolution, improvement or worsened symptoms of dysphonia, or change in QOL of patients with dysphonia after treatment or observation. The guideline update group made a strong recommendation against 1 action: (1) Clinicians should not routinely prescribe antibiotics to treat dysphonia. The guideline update group made recommendations against other actions: (1) Clinicians should not obtain computed tomography (CT) or magnetic resonance imaging (MRI) for patients with a primary voice complaint prior to visualization of the larynx. (2) Clinicians should not prescribe antireflux medications to treat isolated dysphonia, based on symptoms alone attributed to suspected gastroesophageal reflux disease (GERD) or laryngopharyngeal reflux (LPR), without visualization of the larynx. (3) Clinicians should not routinely prescribe corticosteroids for patients with dysphonia prior to visualization of the larynx. The policy level for the following recommendation about laryngoscopy at any time was an option: (1) Clinicians may perform diagnostic laryngoscopy at any time in a patient with dysphonia. Disclaimer This clinical practice guideline is not intended as an exhaustive source of guidance for managing dysphonia (hoarseness). Rather, it is designed to assist clinicians by providing an evidence-based framework for decision-making strategies. The guideline is not intended to replace clinical judgment or establish a protocol for all individuals with this condition, and it may not provide the only appropriate approach to diagnosing and managing this problem.

Allergic laryngitis: unraveling the myths.

PURPOSE OF REVIEW: This article provides a thorough review of the literature highlighting the articles that have advanced our knowledge about the sensitivity of the larynx to allergens in the air or ones consumed. This area of inquiry requires continued interest and investigation. As the field of clinical laryngology changes, and more information is discovered about the possible causal association between allergy and vocal pathologies, practicing otolaryngologists, allergists, and other medical professionals may discover more comprehensive methods to evaluate and treat their allergic patients, particularly those who present with complaints of dysphonia, dysphagia, laryngopharyngeal reflux (LPR), and/or dyspnea. RECENT FINDINGS: There continues to be epidemiological studies designed to describe the relationship of allergy to vocal symptoms and signs. Both population and smaller studies have recently attempted to link these two conditions. Unfortunately, the patient with chronic laryngeal complaints is often tagged by default with the diagnosis of LPR and treated with proton pump inhibitors, which are not always beneficial. The endoscopic assessment may not be as reliable to make the diagnosis of LPR as the examination is subjective and the inter-rater reliability is low. It has been demonstrated by direct laryngeal provocation studies that sticky-viscous endo-laryngeal mucous is the only reliable finding consistently associated with allergy potential allergic tissue reactivity. SUMMARY: The interrelationship of allergic sensitivity and chronic laryngitis in certain individuals is becoming clearer because our knowledge of inquiry has increased and the available routine technology to diagnose these conditions has remarkably improved. Notwithstanding these advancements, much more research is needed on this subject to reduce the frequency of mis-diagnoses and mis-management of allergic patients.

Visual risks of facial fracture repair in the setting of traumatic optic neuropathy.

OBJECTIVE: To identify whether facial fracture repair in patients with traumatic optic neuropathy results in visual deterioration. DESIGN: A retrospective analysis was performed of all patients admitted from 1992 through 1997 with the diagnosis of facial fracture and traumatic optic neuropathy. Vision was recorded before and after fracture repair using logarithm of the minimum angle of resolution measurements. Visual outcome was compared with a nonsurgically treated group of patients with a similar diagnosis. SETTING: University trauma hospital. PATIENTS: A total of 700 medical charts were reviewed, and 54 patients met study criteria. All patients received megadose corticosteroid treatment and were divided into 3 groups: (1) facial fracture repair alone, (2) optic nerve decompression (OND) + facial fracture repair, or (3) nonsurgical treatment. RESULTS: For the 16 patients in the fracture repair alone group, 12 (75%) had improved vision and 4 (25%) had no change postoperatively. For the 10 patients in the OND + fracture repair group, 3 (30%) had improved vision, 5 (50%) had no change, and 2 (20%) had worsened vision postoperatively. For the 28 patients in the nonsurgical group, 18 (64%) had improved vision, 9 (32%) had no change, and 1 (4%) had worsened vision by discharge. Facial fracture repair alone and the nonsurgical groups both demonstrated significant visual improvement by discharge. The amount of improvement was not significantly different between all 3 groups (facial fracture repair, 0.38 +/- 0.40; OND + facial fracture repair; 0.32 +/- 1.38; and nonsurgical, 0.69 +/- 1.07). CONCLUSIONS: Facial fracture repair in the setting of traumatic optic neuropathy had no adverse effect on vision. Patients requiring OND + fracture repair had a significantly worse visual prognosis.

Intradermal positivity after negative prick testing for inhalants.

OBJECTIVE: Examine the incidence of positive intradermal tests after a negative skin prick test for 24 inhalant antigens. STUDY DESIGN AND SETTING: Retrospective study. Charts from patients who underwent modified quantitative testing (MQT) over a 3-year period were reviewed. Patients were initially tested with Multi-Test II. Subjects with negative wheals to a specific allergen were then tested with a 1:500 weight:volume intradermal injection of that allergen. RESULTS: One hundred thirty-three patients underwent MQT for 24 antigens. Allergens with the highest incidence of positive intradermal wheals after negative prick testing were Dermatophagoides pteronyssinus and Dermatophagoides farinae at 26.67%. Allergens with elevated incidence of positive intradermals included fusarium, cockroach, cocklebur, rough marsh elder, and ragweed, all with incidences of 16% to 19%. CONCLUSION: Positive intradermal responses after negative prick testing occur commonly. Future study is needed to determine the generalizability and clinical significance of these findings. EBM RATING: C-4.

Evaluation of Compliance for Treatment of Sudden Hearing Loss: A CHEER Network Study.

OBJECTIVE: The objective of this study is to describe the presentation and management of sudden sensorineural hearing loss for patients seen in academic and community-based practices within the context of the American Academy of Otolaryngology-Head and Neck Surgery Foundation's "Clinical Practice Guideline: Sudden Hearing Loss." The intention is to use these findings to guide implementation strategies and quality improvement initiatives and as pilot data for the development of clinical research initiatives. STUDY DESIGN: A cross-sectional study of patients with sudden hearing loss. SETTING: Patients were recruited from practices within the Creating Healthcare Excellence through Education and Research (CHEER) network. The CHEER network is an National Institutes of Health-funded network of 30 otolaryngology sites across the country, half of which are community based and half of which are academic practices. SUBJECTS AND METHODS: A total of 173 patients were recruited. Data were gathered via custom questionnaires collected by study site coordinators and entered into a secure online platform. Descriptive analyses and correlation statistics were run with SAS 9.3.1. RESULTS: Of the 13 guideline statements in the American Academy of Otolaryngology-Head and Neck Surgery Foundation's clinical practice guideline on sudden hearing loss, 11 statements were evaluable through this study. Compliance for otolaryngologists was >95% for key action statements (KASs) 1, 3, and 6; 90% to 95% for KASs 5 and 10; and <90% for KASs 7 and 13. Compliance was <45% for nonotolaryngologists for KASs 3 and 5-7. CONCLUSIONS: There is opportunity for nonotolaryngologists to improve for statements 3 and 5-7. Otolaryngologists are compliant with many of the KASs overall, but there is significant room for improvement.

Endoscopic ligation of the sphenopalatine artery as a primary management of severe posterior epistaxis in patients with coagulopathy.

We describe our experience with endoscopic ligation of the sphenopalatine artery in the treatment of severe posterior epistaxis in 2 patients with coagulopathy. Conservative treatment had failed in both cases. The key elements of this procedure are the identification of the branches of the sphenopalatine artery via an endoscopic endonasal approach and the application of two titanium clips under direct vision. This procedure was successful in both patients, and we recommend it in selected cases.

Comorbidities of asthma and the unified airway.

BACKGROUND: Asthma is a comorbid condition that may be seen by otolaryngic allergists when treating their patients with allergic rhinitis (AR). Often asthma is overlooked when aggressive treatment could prevent the development or progression of early disease. METHODS: This article is a retrospective review of the current literature on asthma as a comorbidity of the unified airway. The unified airway and asthma are clearly defined. The epidemiology, morbidity, mortality, pathophysiologic mechanisms, and the chronicity of asthma are reviewed. RESULTS: The otolaryngic allergist will become familiar the unified airway concept and the close relationships between AR, chronic rhinosinusitis, and asthma. CONCLUSION: Otolaryngologists should be aware of the unified airway in order to most effectively treat their patients with AR. Knowledge of the close relationships between asthma and AR will help prevent progression of disease, identify early asthma, and improve the outcomes and quality of life for our patients.

Long-Term Survival After Local Resection of Cervical Esophageal Cancer.

Squamous cell carcinoma of the esophagus may be seen in patients with history of head and neck malignancies. Anatomic factors may limit management options. We present a case of second primary early cervical esophageal squamous cell cancer managed by local resection with reconstruction using a radial forearm flap.

Life after Tracheostomy: Patient and Family Perspectives on Teaching, Transitions, and Multidisciplinary Teams.

OBJECTIVE: To report patient/family experiences and outcomes after tracheostomy STUDY DESIGN: International survey of patients and families with tracheostomy. SETTING: Collaboration of the Patient Safety and Quality Improvement Committee of the American Academy of Otolaryngology-Head and Neck Surgery and the Global Tracheostomy Collaborative. METHODS: A 50-item survey was developed with multistakeholder collaboration. The survey was disseminated via international social networks used by patients with a tracheostomy and their families. Qualitative and quantitative data were analyzed. RESULTS: Of 220 respondents, 90% cared for a pediatric patient with a tracheostomy. Only 48% of respondents felt "very prepared" at time of discharge, and 11% did not receive emergency preparedness training prior to discharge. Home nursing needs were inadequately met in 17% of families, with resulting difficulties shortly after discharge; 14% sought emergent care within 1 week of discharge. Nearly half of respondents indicated a desire to have met with a patient with a tracheostomy prior to surgery but were not offered that opportunity. Fragmented care or limited teamwork was reported by 32% of respondents, whereas tracheotomy care was described as "integrated" or "maximally integrated" for 67%. CONCLUSION: While many families report satisfaction with tracheostomy care, opportunities remain for improving care. This study highlights the importance of teaching, teamwork, and smoothing transition from the hospital. Potential quality improvement areas include standardizing tracheostomy teaching for routine and emergency needs and optimizing postdischarge support and coordination. Prior to surgery, connecting families to people with a tracheostomy may also be beneficial.
