Best Practices in Treatment of Laryngopharyngeal Reflux Disease: A Multidisciplinary Modified Delphi Study.

BACKGROUND: Laryngopharyngeal reflux (LPR) is a common otolaryngologic diagnosis. Treatment of presumed LPR remains challenging, and limited frameworks exist to guide treatment. METHODS: Using RAND/University of California, Los Angeles (UCLA) Appropriateness Methods, a modified Delphi approach identified consensus statements to guide LPR treatment. Experts independently and blindly scored proposed statements on importance, scientific acceptability, usability, and feasibility in a four-round iterative process. Accepted measures reached scores with ≥ 80% agreement in the 7-9 range (on a 9-point Likert scale) across all four categories. RESULTS: Fifteen experts rated 36 proposed initial statements. In round one, 10 (27.8%) statements were rated as valid. In round two, 8 statements were modified based on panel suggestions, and experts subsequently rated 5 of these statements as valid. Round three's discussion refined statements not yet accepted, and in round four, additional voting identified 2 additional statements as valid. In total, 17 (47.2%) best practice statements reached consensus, touching on topics as varied as role of empiric treatment, medication use, lifestyle modifications, and indications for laryngoscopy. CONCLUSION: Using a well-tested methodology, best practice statements in the treatment of LPR were identified. The statements serve to guide physicians on LPR treatment considerations.

Zenker's Diverticulum: Readability and Quality of Online Written Education Materials.

To assess the readability and quality of online materials for Zenker's diverticulum. A Google search of "Zenker's diverticulum" was performed and the first 50 websites were reviewed. Readability was measured by Flesch Reading Ease (FRES), Flesch-Kincaid Grade Level (FKGL) and the Simple Measure of Gobbledygook (SMOG) scores using an online calculator. Understandability and actionability were assessed with the Patient Education Materials Assessment Tool for Printed Materials (PEMAT-P). Websites were categorized as either patient-targeted or physician-targeted and unpaired t tests were used to compare scores between these two groups. A total of 31 websites (23 patient-oriented sites and 8 physician-oriented sites) were analyzed. The average FRES, FKGL, and SMOG scores were 29.96 ± 14.72, 13.75 ± 2.78, and 12.19 ± 2.02, respectively, for the entire cohort. Readability scores for the patient-oriented sites were better than the physician-oriented sites for each measure (FRES 36.21 ± 8.86 vs 11.96 ± 13.54, FKGL 12.68 ± 1.58 vs 16.85 ± 3.25, and SMOG 11.37 ± 1.26 vs 14.53 ± 1.98; p < 0.001 for all comparisons). PEMAT-P understandability and actionability scores for the entire cohort were 68.20% ± 10.19% and 10.75% ± 16.52% respectively, and did not differ between patient-oriented and physician oriented sites. Though patient-oriented sites had better readability than physician-oriented sites for Zenker's Diverticulum, both categories had readability levels more advanced than what is recommended for medical education materials.

Does Medialization Improve Swallowing Function in Patients with Unilateral Vocal Fold Paralysis? A Systematic Review.

Glottal incompetence caused by unilateral vocal fold paralysis (UVFP) is a common cause of dysphagia and aspiration. Treatments targeted at reducing glottal incompetence by injection augmentation or medialization thyroplasty are well established at improving voice outcomes, but improvements in swallowing function are less clear. The objective of this systematic review was to determine the impact of vocal fold medialization on dysphagia outcomes. Six electronic bibliographic databases and one clinical trial registry were searched on 3/13/2020. Our patient population were adult patients with verified UVFP that underwent vocal fold medialization. We limited review to prospective studies that had formal dysphagia assessment both before and after medialization. Nine studies met selection criteria (7 prospective case series and 2 prospective cohort studies) totaling 157 patients. The most common etiology of UVFP was iatrogenic (74/157; 47%). The majority of patients underwent injection augmentation (92/157; 59%), and the remaining underwent medialization thyroplasty. A variety of methods were used to assess changes in dysphagia including patient-reported outcome measures, flexible endoscopic evaluation of swallowing, videofluoroscopic swallow study, and high-resolution manometry. 7/9 studies demonstrated clinically significant improvement in swallowing function following medialization; 4/9 studies demonstrated statistically significant improvement, and three studies did not show statistically significant improvement after intervention. Study participants and outcome measures evaluating swallowing function in this review were heterogeneous. Moreover, the reviewed studies are concerning for multiple risks of bias impacting their conclusions. Taken together, this systematic review demonstrates limited evidence that injection augmentation and medialization thyroplasty improve swallowing function and/or safety.

Laryngeal disorders in people living with HIV.

OBJECTIVES: Several studies have shown that HIV infected individuals are at higher risk compared to the general population of developing non-AIDS defining conditions such as some types of cancer, kidney disease, liver disease and others. In this case-control study, we compared the incidence of laryngeal disorders between a treatment-seeking HIV-positive population and uninfected controls. We aimed to investigate whether there are any laryngeal disorders that are overrepresented in HIV-positive individuals. METHODS: This was a case-control study based on retrospective chart review, comparing the incidence of laryngeal, airway, and swallowing disorders in sixty-nine HIV positive individuals and 4178 HIV negative controls treated between January 1, 2016 and December 31, 2017, at the Johns Hopkins Voice Center. RESULTS: A majority of HIV-infected patients (59.4%) had at least one diagnosis belonging to the Vocal cord pathology category compared to 48.2% of controls (OR 1.57, p = 0.065). Compared to the entire treatment-seeking population, HIV patients were more likely to present with laryngeal cancer (15.9% vs. 3.4% in controls, OR 5.43, p < 0.001) and chronic laryngitis (17.4% vs. 4.2%, OR 4.79, p < 0.001). Fungal and ulcerative laryngitis were also overrepresented in HIV-positive individuals (OR 9.45, p < 0.001 and 6.29, p < 0.001, respectively). None of the diagnoses categorized as functional voice disorders, swallowing, or airway problems showed a significant difference between groups. Laryngeal papillomatosis, which is an HPV-dependent disease, had similar prevalence in both groups. CONCLUSIONS: Treatment-seeking HIV-positive patients presenting to a laryngology clinic suffer significantly more often from laryngeal squamous cell carcinoma as well as chronic, fungal, and ulcerative laryngitis compared to HIV-negative individuals. LEVEL OF EVIDENCE: 4.

Laryngeal Injury and Upper Airway Symptoms After Endotracheal Intubation During Surgery: A Systematic Review and Meta-analysis.

Laryngeal injury from intubation can substantially impact airway, voice, and swallowing, thus necessitating multidisciplinary interventions. The goals of this systematic review were (1) to review the types of laryngeal injuries and their patient-reported symptoms and clinical signs resulting from endotracheal intubation in patients intubated for surgeries and (2) to better understand the overall the frequency at which these injuries occur. We conducted a search of 4 online bibliographic databases (ie, PubMed, Embase, Cumulative Index of Nursing and Allied Health Literature [CINAHL], and The Cochrane Library) and ProQuest and Open Access Thesis Dissertations (OPTD) from database inception to September 2019 without restrictions for language. Studies that completed postextubation laryngeal examinations with visualization in adult patients who were endotracheally intubated for surgeries were included. We excluded (1) retrospective studies, (2) case studies, (3) preexisting laryngeal injury/disease, (4) patients with histories of or surgical interventions that risk injury to the recurrent laryngeal nerve, (5) conference abstracts, and (6) patient populations with nonfocal, neurological impairments that may impact voice and swallowing function, thus making it difficult to identify isolated postextubation laryngeal injury. Independent, double-data extraction, and risk of bias assessment followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Collaboration's criteria. Twenty-one articles (1 cross-sectional, 3 cohort, 5 case series, 12 randomized controlled trials) representing 21 surgical studies containing 6140 patients met eligibility criteria. The mean patient age across studies reporting age was 49 (95% confidence interval [CI], 45-53) years with a mean intubation duration of 132 (95% CI, 106-159) minutes. Studies reported no injuries in 80% (95% CI, 69-88) of patients. All 21 studies presented on type of injury. Edema was the most frequently reported mild injury, with a prevalence of 9%-84%. Vocal fold hematomas were the most frequently reported moderate injury, with a prevalence of 4% (95% CI, 2-10). Severe injuries that include subluxation of the arytenoids and vocal fold paralysis are rare (<1%) outcomes. The most prevalent patient complaints postextubation were dysphagia (43%), pain (38%), coughing (32%), a sore throat (27%), and hoarseness (27%). Overall, laryngeal injury from short-duration surgical intubation is common and is most often mild. No uniform guidelines for laryngeal assessment postextubation from surgery are available and hoarseness is neither a good indicator of laryngeal injury or dysphagia. Protocolized screening for dysphonia and dysphagia postextubation may lead to improved identification of injury and, therefore, improved patient outcomes and reduced health care utilization.

Dysphonia and dysphagia as early manifestations of autoimmune inflammatory myopathy.

PURPOSE: While dysphagia is a recognized manifestation of autoimmune inflammatory myopathy, a relationship between myositis and dysphonia or laryngeal pathology is not well-documented. We therefore sought to describe the spectrum of laryngeal disorders present in myositis patients, evaluate whether any specific conditions are overrepresented among these patients compared to a large treatment-seeking population, and examine the clinical course and outcomes of these symptoms. MATERIALS AND METHODS: This was a retrospective chart review, including all patients seen at the Johns Hopkins Voice Center between January 2016 and December 2017. Demographic data, comorbidities, and laryngeal diagnoses were extracted from the electronic medical record. The charts of patients with myositis were reviewed further to ascertain details of their laryngeal symptoms and myositis disease course. Associations between myositis and dysphonia/dysphagia were evaluated using binary regression and multinomial logistic regression models to adjust for age, sex, race, and smoking status. RESULTS: Of 4252 patients, sixteen had myositis. Compared to 4236 controls, these patients had significantly higher odds of presenting with muscular voice disorders (adjusted odds ratio (OR*) = 4.503, p* = 0.005) and dysphagia (OR* = 6.823, p* < 0.001). A majority (64.3%, CI:35.6-93.0%) of myositis patients had laryngeal pathology among the presenting symptoms of their myositis. Across all diagnostic categories, there was a non-significant trend towards better outcomes in patients receiving specific interventions for their laryngeal symptoms. CONCLUSIONS: Muscular voice disorders and dysphagia are significantly overrepresented in myositis patients presenting to a laryngology clinic, and in these patients, both are frequently among the presenting symptoms of myositis.

Impact of subspecialty training on management of laryngopharyngeal reflux: results of a worldwide survey.

OBJECTIVE: To study the management of laryngopharyngeal reflux (LPR) among the subspecialties of practicing otolaryngology-head and neck surgeons and their trainees. METHODS: A survey was sent to over 8000 otolaryngologists (OTOHNS) over 65 countries, utilizing membership lists of participating otolaryngological societies. The outcomes were answers to questions regarding LPR knowledge and practice patterns, and included queries about its definition, prevalence, clinical presentation, diagnosis, and treatment. RESULTS: Of the 824 respondents, 658 practiced in one specific otolaryngologic subspecialty. The symptoms and findings thought to be the most related to LPR varied significantly between subspecialists. Extra-laryngeal findings were considered less by laryngologists while more experienced OTOHNS did not often consider digestive complaints. Compared with colleagues, otologists, rhinologists and laryngologists were less aware of the involvement of LPR in otological, rhinological and laryngological disorders, respectively. Irrespective of subspecialty, OTOHNS consider symptoms and signs and a positive response to empirical therapeutic trial to establish a LPR diagnosis. Awareness regarding the usefulness of impedance pH-studies is low in all groups. The therapeutic approach significantly varies between groups, although all were in agreement for the treatment duration. The management of non-responder patients demonstrated significant differences among laryngologists who performed additional examinations. The majority of participants (37.1%) admitted to being less than knowledgeable about LPR management. CONCLUSIONS: LPR knowledge and management vary significantly across otolaryngology subspecialties. International guidelines on LPR management appear necessary to improve knowledge and management of LPR across all subspecialties of otolaryngology.

Nonepithelial Tumors of the Larynx: Single-Institution 13-Year Review with Radiologic-Pathologic Correlation.

Nonepithelial tumors of the larynx are rare and represent a minority of all laryngeal neoplasms. Imaging has an important role in the diagnosis, treatment planning, and surveillance of these entities. However, unfamiliarity with these neoplasms can cause diagnostic difficulties for radiologists, especially because many of the imaging findings are nonspecific. By using a systematic approach based on clinical history, patient age and gender, lesion location, endoscopic results, and specific imaging findings, the differential diagnosis can often be narrowed. These tumors typically affect the submucosal layer, so if a tumor has an intact mucosa at endoscopy, a nonepithelial neoplasm is the most likely diagnosis. Nonepithelial tumors of the larynx can arise from the laryngeal cartilage or muscle or from the surrounding lymphoid tissue or blood vessels. Consequently, imaging findings typically correspond to the specific cell type from which it originated. Recognizing specific features (eg, metaplastic bone formation, macroscopic fat, or enhancement pattern) can often help narrow the differential diagnosis. In addition, identification of noncircumscribed borders of the lesion and invasion of the adjacent structures is key to diagnosis of a malignant process rather than a benign neoplasm. Understanding the pathologic correlation is fundamental to understanding the radiologic manifestations and is ultimately crucial for differentiation of nonepithelial laryngeal neoplasms.

Is empirical treatment a reasonable strategy for laryngopharyngeal reflux? A contemporary review.

BACKGROUND: Diagnosis and treatment of presumed laryngopharyngeal reflux (LPR) remain controversial. Empiric medication trials remain widespread for suspected LPR despite emerging evidence against proton pump inhibitor (PPI) safety and for pepsin as a mediator of LPR symptoms. Ongoing concerns exist related to inaccurate diagnosis, the cost and morbidity of potentially unnecessary PPI prescriptions, and availability and interpretation of objective reflux testing. OBJECTIVES: To review contemporary evidence that does and does not support empiric medication trials for presumed LPR. METHODS: PubMed, Scopus and Cochrane Library were searched for literature about benefits, limitations and alternatives to empiric medication trial for LPR, in order to present both sides of this debate and identify best practices. RESULTS: The majority of physicians perform prolonged empiric medication trial with PPIs for patients with suspected LPR. Because symptoms and signs of LPR are non-specific, empiric medication trials require exclusion of other conditions that can mimic LPR. Following a PPI empiric medication trial, over one-third of patients remain non-responders. The use of hypopharyngeal-oesophageal multichannel intraluminal impedance-pH monitoring (HEMII-pH) has benefits and limitations in objective diagnosis of LPR. CONCLUSIONS: Use of PPIs for single-agent empiric medication trial does not account for possible non-responders with non-acid or mixed LPR. If LPR diagnosis remains uncertain, alginates can be added to PPI trials. HEMII-pH testing upfront is ideal for patients with suspected LPR, but not always practical; it is indicated when PPI and alginate empiric medication trials have failed or when comorbidities confuse the diagnosis. A more comprehensive, combination therapy empiric medication trial regimen may be needed.

Clinical practice patterns in laryngeal cancer and introduction of CT lung screening.

OBJECTIVES: After the publication of large clinical trials, in January 2014 The U.S. Preventive Services Task Force (USPSTF) recommended annual lung cancer screening with low-dose CT in a well-defined group of high-risk smokers. A significant proportion of patients with laryngeal cancer (LC) meet the introduced criteria, and we hypothesized that clinical practice would change as a result of these evidence-based guidelines. METHODS: Retrospective chart review of patients diagnosed with LC and treated at Johns Hopkins Hospital who met USPSTF criteria for annual chest screening and were followed for at least 3 consecutive years in the years surrounding the introduction of screening guidelines (January 2010 to December 2017) was performed to identify those who had recommended screening CT chest. RESULTS: A total of 151 patients met the inclusion criteria of the study and were followed for a total of 746 patient-years. 184/332 (55%) patient-years in the pre-guidelines period and 246/414 (59%) in the post-guidelines period included at least one recommended chest imaging (CT or PET-CT; p = 0.27). 248/332 (75%) patient-years in the pre-guidelines period and 314/414 (76%) in the post-guidelines period included any radiological chest imaging (X-ray, CT or PET-CT; p = 0.72). Screening scans were ordered by OHNS (45%), Medical Oncology (31%), Radiation Oncology (8%), and primary care (14%) with 70% of patients missing at least one year of indicated screening. CONCLUSIONS: The implementation of new lung cancer screening guidelines did not change clinical practice in the management of patients with LC and many patients do not receive recommended screening. Further study concerning potential barriers to effective evidence-based screening and coordination of care is warranted.

Molecular and immunologic analysis of laryngeal squamous cell carcinoma in smokers and non-smokers.

BACKGROUND: Laryngeal squamous cell carcinoma (LSCC) is strongly associated with tobacco use, but recent reports suggest an increasing incidence of LSCC in patients without traditional risk factors, suggesting an alternative etiology of tumorigenesis. The purpose of this study is to characterize this non-smoking population and to compare immunohistochemical markers in tumor specimens from non-smokers and smokers with LSCC. METHODS: A retrospective chart review of patients with LSCC at Johns Hopkins Hospital (JHH) was performed. A tissue microarray (TMA) was constructed with tumor specimen from non-smokers with stage and age-matched smokers and stained for a variety of immunologic and molecular targets. RESULTS: In the JHH cohort of 521 patients, 12% (n = 63) were non-smokers. Non-smokers were more likely to be <45 years old at time of diagnosis (OR 4.13, p = 0.001) and to have glottic tumors (OR 2.46, p = 0.003). The TMA was comprised of tumors from 34 patients (14 non-smokers, 20 smokers). Only 2 patients (6%) were human-papillomavirus (HPV) positive by high-risk RNA in situ hybridization (ISH). There was no correlation between smoking status and p16 (p = 0.36), HPV-ISH positivity (p = 0.79), phosphatase and tensin homolog (PTEN, p = 0.91), p53 (p = 0.14), or programmed death-ligand 1 (PD-L1, p = 0.27) expression. CONCLUSIONS: Non-smokers with LSCC are more likely to be younger at the time of diagnosis and have glottic tumors than smokers with LSCC. In TMA analysis of stage and age-matched specimens from smoker and non-smokers with LSCC, the pattern of expression for common molecular and immunologic markers is similar. Further, HPV does not appear to be a major causative etiology of LSCC in either smokers or non-smokers in our cohort of patients.

The management of suspected or confirmed laryngopharyngeal reflux patients with recalcitrant symptoms: A contemporary review.

OBJECTIVE: To summarise current knowledge about the prevalence, aetiology and management of recalcitrant laryngopharyngeal reflux (LPR) patients-those who do not respond to anti-reflux medical treatment. METHODS: A literature search was conducted following the PRISMA guidelines to identify studies that reported success of anti-reflux medical treatment with emphasis on studies that attempted to be rigorous in defining a population of LPR patients and which subsequently explored the characteristics of non-responder patients (ie aetiology of resistance; differential diagnoses; management and treatment). Three investigators screened publications for eligibility from PubMED, Cochrane Library and Scopus and excluded studies based on predetermined criteria. Design, diagnostic method, exclusion criteria, treatment characteristics, follow-up and quality of outcome assessment were evaluated. RESULTS: Of the 139 articles screened, 45 met the inclusion criteria. The definition of non-responder patients varied substantially from one study to another and often did not include laryngopharyngeal signs. The reported success rate of conventional therapeutic trials ranged from 17% to 87% and depended on diagnostic criteria, treatment scheme, definition of treatment failure and treatment outcomes that varied substantially between studies. The management of non-responders differed between studies with a few differential diagnoses reported. No study considered the profile of reflux (acidic, weakly acid, non-acid or mixed) or addressed personalised treatment with the addition of alginate or magaldrate, low acid diet, or other interventions that have emerging evidence of efficacy. CONCLUSION: To date, there is no standardised management of LPR patients who do not respond to traditional treatment approached. A diagnostic and therapeutic algorithm is proposed to improve the management of these patients. Future studies will be necessary to confirm the efficacy of this algorithm through large cohort studies of non-responder LPR patients. LEVEL OF EVIDENCE: 2a.

Laryngeal Injury and Upper Airway Symptoms After Oral Endotracheal Intubation With Mechanical Ventilation During Critical Care: A Systematic Review.

OBJECTIVES: To systematically review the symptoms and types of laryngeal injuries resulting from endotracheal intubation in mechanically ventilated patients in the ICU. DATA SOURCES: PubMed, Embase, CINAHL, and Cochrane Library from database inception to September 2017. STUDY SELECTION: Studies of adult patients who were endotracheally intubated with mechanical ventilation in the ICU and completed postextubation laryngeal examinations with either direct or indirect visualization. DATA EXTRACTION: Independent, double-data extraction and risk of bias assessment followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Risk of bias assessment followed the Cochrane Collaboration's criteria. DATA SYNTHESIS: Nine studies (seven cohorts, two cross-sectional) representing 775 patients met eligibility criteria. The mean (SD; 95% CI) duration of intubation was 8.2 days (6.0 d; 7.7-8.7 d). A high prevalence (83%) of laryngeal injury was found. Many of these were mild injuries, although moderate to severe injuries occurred in 13-31% of patients across studies. The most frequently occurring clinical symptoms reported post extubation were dysphonia (76%), pain (76%), hoarseness (63%), and dysphagia (49%) across studies. CONCLUSIONS: Laryngeal injury from intubation is common in the ICU setting. Guidelines for laryngeal assessment and postextubation surveillance do not exist. A systematic approach to more robust investigations could increase knowledge of the association between particular injuries and corresponding functional impairments, improving understanding of both time course and prognosis for resolution of injury. Our findings identify targets for future research and highlight the long-known, but understudied, clinical outcomes from endotracheal intubation with mechanical ventilation in ICU.

How to Approach Laryngopharyngeal Reflux: An Otolaryngology Perspective.

In the otolaryngology practice, there is a rising concern with the current diagnosis and management of laryngopharyngeal reflux (LPR). The implication of LPR in many common head and neck symptoms, along with the rising cost of empiric therapy and no overall improvement in patient symptoms, has established a need to review what are indeed laryngopharyngeal complaints secondary to reflux and what are not. This article reviews the otolaryngologist's approach to LPR, the various ways diagnosis is made, and the guidelines that inform the current trends in otolaryngology management of LPR. The goal of this article is to recognize that reflux can be the cause of a variety of laryngopharyngeal complaints seen within an otolaryngology practice, but when empiric therapy does not improve symptoms, consideration should be given to other non-reflux causes.

Predictors of Posterior Glottic Stenosis: A Multi-Institutional Case-Control Study.

OBJECTIVE: To assess intrinsic and extrinsic risk factors in the development of posterior glottic stenosis (PGS) in intubated patients. METHODS: Patients diagnosed with PGS between September 2012 and May 2014 at 3 tertiary care university hospitals were included. Patient demographics, comorbidities, duration of intubation, endotracheal tube (ETT) size, and indication for intubation were recorded. Patients with PGS were compared to control patients represented by patients intubated in intensive care units (ICU). RESULTS: Thirty-six PGS patients were identified. After exclusion, 28 PGS patients (14 male, 14 female) and 112 (65 male, 47 female) controls were studied. Multivariate analysis demonstrated ischemia (P < .05), diabetes (P < .01), and length of intubation (P < .01) were significant risk factors for the development of PGS. Fourteen of 14 (100%) males were intubated with a size 8 or larger ETT compared to 47 of 65 (72.3%) male controls (P < .05). Posterior glottic stenosis (P < .01), length of intubation (P < .001), and obstructive sleep apnea (P < .05) were significant risk factors for tracheostomy. CONCLUSION: Duration of intubation, ischemia, diabetes mellitus, and large ETT size (8 or greater) in males were significant risk factors for the development of PGS. Reducing the use of size 8 ETTs and earlier planned tracheostomy in high-risk patients may reduce the incidence of PGS and improve ICU safety.

Changing Patterns in Reflux Care: 10-Year Comparison of ABEA Members.

OBJECTIVES: To compare patterns of laryngopharyngeal reflux (LPR) diagnosis and management over time by American Broncho-Esophagological Association (ABEA) members. METHODS: American Broncho-Esophagological Association members completed an online questionnaire focused on LPR evaluation and management in 2012; responses were compared to a 2002 survey. RESULTS: Four hundred twenty-six members were emailed, of whom 63 (14.8%) responded. In both time periods, throat clearing, heartburn, globus, arytenoid edema, and erythema were considered highly related to LPR. Management in 2012 differed as respondents more commonly treated LPR empirically (82.6% vs 56.3%, P = .036). When adjunctive testing was ordered, dual pH probe were less frequently utilized in 2012 (61.5% vs 78.3%, P = .029). Either esophagogastroduodenoscopy (EGD) or transnasal esophagoscopy (TNE) was used more often in 2012 compared to EGD alone in 2002 (63.8% vs 42.4%, P = .020). Dual pH probe was regarded as the most sensitive and specific evaluation for LPR in both surveys, while the perceived sensitivity/specificity of EGD in 2012 was half that reported in 2002 (28.0% vs 56.3%, P = .003). CONCLUSION: Attitudes of ABEA members toward empiric treatment and adjunctive tests have changed between 2012 and 2002. While pH probe testing remains the test regarded as most sensitive/specific for evaluation of LPR, empiric management has become more common. Meanwhile, EGD use has increased despite a significant decrease in its perceived sensitivity/specificity.

Voice quality in laryngotracheal stenosis: impact of dilation and level of stenosis.

OBJECTIVE: To assess the impact of suspension microlaryngoscopy with balloon dilation on voice-related quality of life (V-RQOL) in laryngotracheal stenosis (LTS). METHODS: Retrospective chart review of LTS patients dilated at a tertiary-care academic hospital from 2010 to 2013. Data were obtained and then analyzed. LTS was stratified by (1) subglottic or tracheal stenosis and (2) multilevel stenosis (MLS; glottic and subglottic/tracheal). Pre- and postoperative V-RQOL and grade, roughness, breathiness, asthenia, strain (GRBAS) scores were compared. The number and frequency of balloon dilation procedures over the lifetime were secondary outcome variables. RESULTS: Thirty-eight patients were identified: 26 subglottic/tracheal and 12 multilevel. Of these, 71.4% required multiple dilations, with greatest dilations/patient for multilevel stenosis (4.8). V-RQOL improved in the 27 patients with completed pre- and postoperative scores from a mean of 70.4 to 80 (P=.025). Pre/postoperative V-RQOLs for tracheal/subglottic (mean, 82.8/93.8) were significantly higher (P=.0001/.0001) than multilevel stenosis (48/55.3). Voice quality-of-life improvement was significant for the subglottic/tracheal cohort (P=.036) but not for the MLS group. GRBAS was performed pre- and postoperatively in 10 patients with improvement in all domains except breathiness. CONCLUSION: Laryngotracheal stenosis is associated with dysphonia. Patients with glottic involvement have significantly worse voice quality of life than those with tracheal/subglottic stenosis. Endoscopic balloon dilation improves V-RQOL in patients with subglottic/tracheal stenosis.

Attendance in voice therapy: can an interdisciplinary care model have an impact?

OBJECTIVES: We sought to determine the effect of referral patterns on attendance in voice therapy. METHODS: Patients who were seen by a laryngologist for vocal concerns and referred for voice therapy comprised the study population. Outcomes were compared between those who were initially evaluated through the interdisciplinary voice clinic (IDC), which combined speech-language pathology and laryngology care, and those who were evaluated by a laryngologist alone. Adherence was measured by completion of the plan of care. RESULTS: There were 79 patients evaluated through the IDC and 100 patients evaluated initially by a laryngologist. Patients evaluated through the IDC had more visits with the speech-language pathologist (mean, 3.1 versus 1.24; p < 0.0001). Those initially evaluated through the IDC were more likely to complete their plan of care (p = 0.02). Completion of voice therapy was significantly more likely for individuals coded as being of "other" race (odds ratio, 7.98; p = 0.002) and for patients who participated in the IDC (odds ratio, 2.56; p = 0.018). The cause of dysphonia, sex, marital status, insurance status, days from laryngology referral to the initial speech-language pathologist consultation, the initial Voice-Related Quality of Life score, and distance to the clinic were not associated with patient attendance. CONCLUSIONS: Patients evaluated in a coordinated IDC should be more likely to attend voice therapy and complete their plan of care, regardless of other factors.

Laryngopharyngeal reflux: paradigms for evaluation, diagnosis, and treatment.

OBJECTIVE: This study aimed to describe current patterns for diagnosis and treatment of laryngopharyngeal reflux (LPR) and analyze differences between laryngologists and non-laryngologists. METHODS: American Academy of Otolaryngology-Head and Neck Surgery and American Broncho-Esophagological Association members were invited to complete an online survey regarding evaluation, diagnosis, and treatment of LPR. Subgroup analysis was performed to identify differences between respondents who completed laryngology fellowships (LF) and those who did not (NL). RESULTS: Of 159 respondents, 40 were LF. Video documentation of laryngopharyngeal exams was almost universal among LF (97% vs 38%, P < .0001). Use of rigid (100%, P = .002) and flexible distal-chip technologies (94%, P = .004) was more common among LF. Diagnostic criteria were similar between the groups, with symptoms of heartburn, globus, and throat clearing thought most suggestive of LPR. Adjunctive tests most commonly used were barium esophagram and dual-probe pH testing with impedance. Laryngology fellowship-trained respondents used dual pH probes with impedance more often (P = .004). They were more likely to prescribe twice daily proton pump inhibitors with concurrent H2-blocker medication initially (P = .004) and to treat for longer than 4 weeks (P = .0003). CONCLUSION: Otolaryngologists are in agreement on symptoms and physical features of LPR; however, significant differences exist between laryngologists and non-laryngologists on the use of adjunctive testing and treatment strategies.

Dysphagia, short-term outcomes, and cost of care after anterior cervical disc surgery.

Dysphonia and dysphagia are common complications of anterior cervical discectomy (ACD). We sought to determine the relationship between dysphagia and in-hospital mortality, complications, speech therapy/dysphagia training, length of hospitalization, and costs associated with ACD. Discharge data from the Nationwide Inpatient Sample for 1,649,871 patients who underwent ACD of fewer than four vertebrae for benign acquired disease between 2001 and 2010 were analyzed using cross-tabulations and multivariate regression modeling. Dysphagia was reported in 32,922 cases (2.0 %). Speech therapy/dysphagia training was reported in less than 0.1 % of all cases and in only 0.2 % of patients with dysphagia. Dysphagia was significantly associated with age ≥65 years (OR = 1.5 [95 % CI 1.4-1.7], P < 0.001), advanced comorbidity (OR = 2.3 [2.0-2.6], P < 0.001), revision surgery (OR = 2.7 [2.3-3.1], P < 0.001), disc prosthesis placement (OR = 1.5 [1.0-2.0], P = 0.029), and vocal cord paralysis (OR = 11.6 [8.3-16.1], P < 0.001). Dysphagia was a significant predictor of aspiration pneumonia (OR = 8.6 [6.7-10.9], P < 0.001), tracheostomy (OR = 2.3 [1.6-3.3], P < 0.001), gastrostomy (OR = 30.9 [25.3-37.8], P < 0.001), and speech therapy/dysphagia training (OR = 32.0 [15.4-66.4], P < 0.001). Aspiration pneumonia was significantly associated with in-hospital mortality (OR = 15.9 [11.0-23.1], P < 0.001). Dysphagia, vocal cord paralysis, and aspiration pneumonia were significant predictors of increased length of hospitalization and hospital-related costs, with aspiration pneumonia having the single largest impact on length of hospitalization and costs. Dysphagia is significantly associated with increased morbidity, length of hospitalization, and hospital-related costs in ACD patients. Despite the known risk of dysphagia in ACD patients and an established role for the speech-language pathologist in dysphagia management, speech-language pathology intervention appears underutilized in this population.
