RESUMEN

Importance: The 1996 Tonsillectomy and Adenoidectomy Inpatient Guidelines of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) Pediatric Otolaryngology Committee recommended that children younger than 3 years be admitted following tonsillectomy. Recommendations for hospital observation were not included as a key action statement in the 2011 AAO-HNS Clinical Practice Guidelines for Tonsillectomy in Children. Objective: To examine the association between posttonsillectomy complication rate and the age and weight of the child at the time of surgery. Design, Setting, and Participants: This was a multicenter case series study with medical record review of 2139 consecutive children ages 3 to 6 years who underwent tonsillectomy at 1 tertiary care academic center and 5 acute care centers in New Orleans, Louisiana, between 2005 and 2015. Children with moderate to severe developmental delay, bleeding disorders, and other major medical comorbidities were excluded. Main Outcomes and Measures: Complications examined included respiratory distress, dehydration requiring intravenous fluids, and bleeding. Results: Of the 2139 patients, 1817 met inclusion criteria. A total of 1011 (55.6%) were male. The mean (SD) age at the time of the procedure was 46 (14) months (range, 12-72 months). The mean weight at the time of the procedure was 17 (5) kg (range, 9-43 kg). A total of 95 patients (5.2%) had a postoperative complication. Of the 455 children younger than 3 years in the study, 32 (7.0%) had complications compared with 63 (4.6%) of the 1362 patients 3 years or older. The odds of having a complication in children younger than 3 years was 1.5 times greater than it was in children 3 years or older (odds ratio [OR], 1.56; 95% CI, 1.00-2.42). When examining total complications, children younger than 3 years were more likely to experience a complication within the first 24 hours after surgery than children 3 years or older (25% vs 9.5%; OR, 3.17; 95% CI, 1.00-10.11). The children admitted to the hospital had a greater risk of complication than those treated as an outpatient, independent of age (6.9% vs 93.0%; OR, 3.49; 95% CI, 2.0.18-6.05). No association between weight and complications was found on logistic regression (area under the curve = 0.5268; P = .66). Conclusions and Relevance: Healthy children younger than 3 years may be at an increased risk for complication following tonsillectomy. Those children may also be at increased risk for complications within the first 24 hours after surgery compared with children 3 years or older. Our data suggest that complications are independent of weight in these patients. In our cohort, those patients selected for overnight observation were associated with an increased number of adverse events following tonsillectomy, suggesting that clinician judgment is crucial in determining which patients are safe for outpatient tonsillectomy.

RESUMEN

A previously healthy 5-week-old female was admitted for sepsis secondary to methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. After several days of hospitalization, she experienced acute decompensation in mental status despite having received targeted antibiotic therapy. Imaging revealed left peritonsillar/parapharyngeal space abscess, left venous thrombophlebitis of the internal jugular vein, and septic emboli of the lungs and brain consistent with Lemierre syndrome. Bedside needle aspiration of the parapharyngeal abscess confirmed MRSA involvement. Unfortunately, the patient continued to deteriorate over the next several days and life support was withdrawn on hospital day 16. We present the youngest reported case of Lemierre syndrome and review the literature.

RESUMEN

Osteochondromas, the most common benign bone tumors, are cartilaginous neoplasms of unknown origin with rare malignant potential. Osteochondromas rarely occur in the head and neck, and diagnosis relies on a combination of clinical, radiological, and histological criteria. Excision is often curative. We describe the first reported case of hyoid osteochondroma in an adolescent male with multiple osteochondroma, discuss its surgical management, and perform a review of the salient literature. Osteochondroma represents a rare diagnosis to include in the differential of any midline neck mass.

RESUMEN

Objective To determine the impact of adenotonsillectomy on the quality of life of pediatric patients with obstructive sleep apnea (OSA) and to identify gaps in the current research. Data Sources The MEDLINE, EMBASE, and Cochrane databases were systematically searched via the Ovid portal on June 18, 2016, for English-language articles. Review Methods Full-text articles were selected that studied boys and girls <18 years of age who underwent adenotonsillectomy for OSA or sleep-disordered breathing and that recorded validated, quantitative quality-of-life outcomes. Studies that lacked such measures, performed adenotonsillectomy for indications other than OSA or sleep-disordered breathing, or grouped adenotonsillectomy with other procedures were excluded. Results Of the 328 articles initially identified, 37 were included for qualitative analysis. The level of evidence was generally low. All studies involving short-term follow-up (≤6 months) showed improvement in quality-of-life scores after adenotonsillectomy as compared with preoperative values. Studies involving long-term follow-up (>6 months) showed mixed results. Modifications to and concurrent procedures with conventional adenotonsillectomy were also identified that showed quality-of-life improvements. Three studies were identified for meta-analysis that compared pre- and postoperative Obstructive Sleep Apnea-18 scores. Short- and long-term follow-up versus preoperative scores showed significant improvement ( P < .001). Short- and long-term scores showed no significant difference. Conclusion This systematic review and meta-analysis demonstrate adenotonsillectomy's effectiveness in improving the quality of life of pediatric patients with OSA. This is well demonstrated in the short term and has strong indications in the long term.

RESUMEN

OBJECTIVE: To examine the efficacy of polysomnography in determining the severity of laryngomalacia in pediatric patients. METHODS: Prospective cohort study. Pediatric patients referred to our pediatric otolaryngology department with a polysomnogram already performed for a presumptive diagnosis of laryngomalacia were enrolled in the study. Patients with concurrent airway lesions or neuromuscular disorders were excluded. Patients underwent history, physical exam, and flexible fiberoptic laryngoscopy. These results were used to calculate a total laryngomalacia severity score. RESULTS: 25 pediatric patients (n = 25) with an average age of 3.9 months at time of initial evaluation met criteria for enrollment in our study. 100% of patients had obstructive sleep apnea by definition. 80% of these patients underwent supraglottoplasty. The average AHI of those who underwent surgery (57.26) was not significantly different in those who underwent surgery vs. those that did not (55.43) (p = 0.41). In comparison, the average laryngomalacia severity score based from history, physical exam and flexible laryngoscopy was significantly greater in the patients that required supraglottoplasty (11.16) vs. those who did not (5.33) (p = 0.03). In addition a higher laryngomalacia severity score was not correlated with a higher AHI (p = 0.81, r = 0.08, CI: -0.5197 to 0.6235). CONCLUSION: In our cohort, polysomnography was not useful in determining the severity of laryngomalacia, did not correlate with the clinical evaluation, and alone was not predictive of the patients that would require surgical intervention. History, physical exam, and endoscopic findings remain reliable predictors of disease severity and need for operative intervention.

RESUMEN

Objectives/Hypothesis: The human cochlea is most commonly considered to have two and a half turns. Although the causes of cochlear hypoplasia are well described, cochlear hyperplasia is a rarer entity that is poorly understood. We describe rare anatomic cochlear malformations identified in a 4-month-old male originally referred for evaluation after a failed newborn hearing screening. The full diagnostic evaluation, imaging findings, treatment, and follow-up are described in detail. Cochleae with three turns are an uncommon malformation that is not included in current classifications schemes and may represent a distinct type of anomaly not caused by developmental arrest.

RESUMEN

OBJECTIVES: To identify factors associated with efficient operating room work flow on high volume pediatric otolaryngology days and the effects on provider and perceived parent satisfaction. METHODS: Retrospective review was performed of a sample of 20 days with greater than 10 cases per day performed by a pediatric otolaryngologist operating in 2 rooms. Turnover time and complications were the main outcome measures. Providers from otolaryngology and anesthesia that participated in these days were surveyed regarding efficiency, safety, and satisfaction. RESULTS: 223 cases were performed over 20 operative days. The average turnover time was significantly longer in "major" surgeries (p=0.03), cases with multispecialty involvement (p=0.01), cases requiring intubation (p<0.001), and in cases where a fellowship trained pediatric anesthesiologist (p=0.01) or CRNA was present (p<0.001). When comparing "fast" (<25min average turnover) operative days vs. "slow" (>25min average turnover) days, presence of a non-fellowship trained anesthesiologist (p<0.001), and the presence of an anesthesiology resident (p=0.03) were significantly associated with "fast" days, while the presence of a CRNA was associated with "slow" days (p<0.001). A significantly greater proportion of patients required intubation on "slow" turnover days vs. "fast" days (p=0.13). Only one complication was observed (0.4%). 48 providers were surveyed with a 63% response rate. Reported satisfaction amongst providers was significantly greater on days with at least 10 cases (p=0.047) and on days with turnover times of 25min or less (p<0.001). Pre-operative nursing evaluation/preparation of the patient, inter-provider communication and delays in room cleaning/setup were identified most often as causative factors responsible for delays in turnover. CONCLUSIONS: High-operative volume operating days are common in pediatric otolaryngology and can be safely performed in an efficient manner. Appropriate scheduling and high-level communication between providers is needed to ensure success on these days. Identified areas of potential inefficiency can be a starting point for work flow optimization practices.

RESUMEN

Juvenile ossifying fibroma is a rare, benign tumor that may present in the sinonasal area but has never been described arising from the middle turbinate. The lesion's locally aggressive behavior and close proximity to orbit and anterior skull base create a significant challenge for the patient and practitioner. This is a case presentation of a 7-year-old female with an invasive recurrent juvenile ossifying fibroma arising from the middle turbinate.

RESUMEN

BACKGROUND: Cystic fibrosis (CF) is an autosomal recessive genetic disease that affects approximately 30,000 people in the United States. Mucus in CF patients can be exceptionally viscous, leading to progressive cycles of inflammation and infection. The most widely accepted staging system used to score sinus computed tomography (CT) scans is the Lund-Mackay Score (LMS). METHODS: To determine if a significant correlation exists between LMS and the need for revision sinus surgery in a patient population with CF, we performed a retrospective review of 32 patients with CF who were referred to the Tulane Otolaryngology Clinic from 2005 to 2011 and received a CT scan of the paranasal sinuses. CT scans were graded in a blinded manner by the institution's neuroradiologist using the LMS system. RESULTS: We found no statistically significant difference in the raw or scaled LMSs between patients receiving revision surgery (n=9) and patients receiving a single surgery (n=23). CONCLUSIONS: CT scans are vital for preoperative planning, but they are not a useful tool for risk stratification. More specifically, application of the LMS is not relevant in identifying which CF patients with chronic rhinosinusitis will be at risk for revision surgeries.

RESUMEN

Rosai Dorfman disease (RD), also known as sinus histiocytosis with massive lymphadenopathy (SHML), is a benign histiocytic proliferative condition of unsubstantiated etiology that most often presents as bilateral painless cervical lymphadenopathy. Head and neck manifestations of RD are diverse but most commonly present as massive cervical lymphadenopathy. Interestingly, a retropharyngeal fluid collection has never been described as a sequelae of RD. Our objective is to present a novel case of a 9-year old female with RD that suffered from recurrent retropharyngeal phlegmon and to discuss diagnostic and treatment recommendations for this disease process.

RESUMEN

BACKGROUND: The most common lysosomal storage disorder, Gaucher disease, represents a collection of 3 clinical syndromes associated with disrupted glucocerebroside catabolism. Despite the common occurrence of dyspnea in advanced Gaucher, dyspnea is rarely reported as a presenting symptom of the disease. CASE REPORT: A 10-month-old male was referred to the Otolaryngology Clinic for evaluation of progressive dyspnea. Physical examination was significant for cervical adenopathy, inspiratory stridor, and developmental delay. A complete evaluation for failure to thrive and lymphadenopathy was performed, with subsequent lymph node biopsy and enzyme assay confirming the presence of Gaucher disease. CONCLUSION: A high level of suspicion is required to make an early diagnosis of Gaucher disease, but it should be considered in patients presenting with failure to thrive, generalized lymphadenopathy, and respiratory or neurologic findings. Initiation of early treatment is paramount for the prevention of irreversible disease.

RESUMEN

OBJECTIVE: Laryngopharyngeal reflux (LPR) is the disorder caused by the regurgitation of gastric contents into the laryngopharynx. Many persons diagnosed with LPR who fail medical therapy regurgitate contents from the proximal esophagus into the laryngopharynx (esophagopharyngeal reflux or EPR) on cinefluoroscopy. STUDY DESIGN: Retrospective review. SUBJECTS AND METHODS: The charts of consecutive adult patients with findings of EPR on cinefluoroscopy were reviewed. RESULTS: Twenty patients met the diagnostic criteria for EPR (mean age, 50 years of age; 60% female). Most common symptoms were cough (40%), dysphagia (35%), dysphonia (25%), and chronic throat clearing (25%). Eighty-five percent had a prior diagnosis of acid reflux disease (LPR or GER) and were unsuccessfully treated with proton pump inhibitors and/or anti-reflux surgery; 15% had fluoroscopic oropharyngeal abnormalities; all patients had fluoroscopic esophageal abnormalities. CONCLUSION: EPR is characterized by regurgitation of proximal esophageal contents into the laryngopharynx. The symptoms are similar to LPR. EPR appears to be caused by a disorder of volume clearance and esophageal dysmotility not acid and peptic injury.

RESUMEN

PURPOSE: To compile information regarding obstructive subglottic lesions in children, including anatomy, pathogenesis, prevention, evaluation, and treatment options, required for implementation of a multi-faceted treatment plan. METHOD: Review of the literature. CONCLUSIONS: Although they are infrequent, obstructive subglottic lesions pose significant challenges to treating physicians, from airway management and injury prevention to decannulation and voice rehabilitation. Most patients with these lesions require multidisciplinary care and long-term treatment and can nearly always be treated successfully.

RESUMEN

OBJECTIVE: To evaluate the presentation, imaging characteristics and treatment outcome of pleomorphic adenoma of the parotid in the pediatric population. DESIGN: Retrospective study with institutional review board approval. SETTING: Tertiary care pediatric medical center. METHODS: An extensive review of medical records with regard to presentation, imaging, histopathology, complication, recurrence and prognosis on patients 18 years or younger presenting from 1983 to 2005. RESULTS: Eleven patients (six females, five males) were identified. The most common presentation was an asymptomatic mass. Preoperative imaging was done on nine patients: MRI (N=6), CT (N=3), ultrasound (N=2), and sialogram (N=1). Initial treatments included: superficial parotidectomy (N=5), total parotidectomy (N=3), excisional biopsy followed by superficial parotidectomy (N=2), and excisional biopsy (N=1). There were two recurrences (18%); one presenting 7 months following excisional biopsy who underwent superficial parotidectomy and one occurred 3 years following total parotidectomy requiring revision parotidectomy and radiation. Other complications included: transient facial nerve paresis (N=5; 45%) and permanent weakness (N=1; 9%). The patients were followed an average of 18 months. CONCLUSIONS: Pleomorphic adenoma is one of the most common tumors of the parotid in children. The most common presentation is an asymptomatic mass. A preoperative evaluation with MRI or CT scan can be helpful in determining the extent of the lesion and surgical planning. Complete excision via superficial or total parotidectomy with preservation of facial nerve is the treatment of choice. Long-term follow up is recommended, though was difficult in a tertiary care center.

RESUMEN

OBJECTIVES: Fiberoptic endoscopic evaluation of swallowing with sensory testing has been used to assess the integrity of laryngopharyngeal sensory and motor components. The pharyngeal squeeze is a maneuver used during fiberoptic endoscopic evaluation of swallowing with sensory testing to assess pharyngeal motor function. Although the pharyngeal squeeze manuever has been used in numerous scientific publications, its reliability has not been critically evaluated. Therefore, we sought to evaluate the reliability of the pharyngeal squeeze maneuver. METHODS: Forty individuals who were undergoing fiberoptic laryngoscopy for various reasons were instructed to perform the pharyngeal squeeze maneuver. Three different clinicians reviewed the videotape on 4 separate occasions. The clinicians were first asked to rate each side of the pharynx as normal, diminished, or absent. They were then instructed to simply rate the maneuver as normal or abnormal. The interobserver and intraobserver reliability of the pharyngeal squeeze maneuver were assessed with the kappa coefficient. RESULTS: The mean age of the cohort was 58 years. Fifty-eight percent (23 of 40) were male. When the clinicians were instructed to rate each side of the pharynx as normal, diminished, or absent, the interobserver and intraobserver reliabilities were poor (63% to 68% agreement; kappa = 0.18 to 0.67). When the clinicians were asked to rate the pharyngeal squeeze maneuver as normal or abnormal, both interobserver and intraobserver reliabilities were excellent (85% to 98% agreement; kappa = 0.75 to 0.95). CONCLUSIONS: The pharyngeal squeeze maneuver displayed poor reliability when motor function was classified into unilateral or bilateral normal, diminished, and absent categories. The pharyngeal squeeze maneuver was very reliable when simply graded as normal or abnormal. Clinicians could not reliably distinguish between diminished and absent pharyngeal motor functions.

RESUMEN

The development of the middle and inner ear highlights the intricacy of embryology. As early as 3 weeks after fertilization, the inner ear begins taking form. This process, along with development of the middle ear, continues throughout gestation. At birth, the middle ear, inner ear, and associated structures are almost adult size. An understanding of the embryologic development of the ear serves as a foundation for evaluating and managing congenital malformations of these structures. The focus of this article is the normal, abnormal, and arrested development of the middle and inner ear, with a clinical emphasis on malformed middle and inner ear structures and a discussion of associated syndromes.

RESUMEN

Hemifacial microsomia is the second most common congenital facial anomaly, second only to cleft lip and palate. While its precise etiology is not yet known, it is likely caused by a disruption in the development of the first two branchial arches early in embryologic development. The resulting phenotype is one of varying degrees of unilateral hypoplasia of the mandible, ear deformity, and macrostomia. Early diagnosis of hemifacial microsomia is important not only to plan for surgical reconstruction of affected features, but also to lead the physician in further evaluation for associated abnormalities or disabilities. This article will introduce the reader to the most common variants seen in hemifacial microsomia, discuss the possible etiologies of the anomalies, and will highlight the importance of evaluating these patients early in life for such potentially disabling but correctable problems such as hearing loss, feeding disabilities, and neurological deformities.

RESUMEN

OBJECTIVE: To describe partial adenoidectomy using a powered microdebrider and review the experience with the procedure. STUDY DESIGN: Prospective study and review. METHODS: To perform a power-assisted partial adenoidectomy, the surgeon directs the window in the microdebrider blade tip toward the tissue, which is drawn in by suction; the rotating blade then shaves the tissue. Studies have compared this adenoidectomy technique with curette procedures. RESULTS: In a comparative prospective study, we found that operating time and time required for hemostasis were significantly shorter (P =.001) with power-assisted partial adenoidectomy than with curettage. There was no significant difference between the two procedures in blood loss or complication rate. These results were similar to those of previous studies. Overall, we have performed more than 1000 power-assisted partial adenoidectomies. No long-term complications have occurred, blood loss remains low, and surgeons are satisfied with the technique because of its speed, improved visibility during resection, and precision. CONCLUSION: We and other authors have found power-assisted partial adenoidectomy to provide a faster, more precise operation than curette techniques, with benefits for both patient and surgeon.
