Polysomnogram outcomes in patients with laryngomalacia and obstructive sleep apnoea treated surgically versus non-surgically.

OBJECTIVE: To compare supraglottoplasty versus non-surgical treatment in children with laryngomalacia and mild, moderate and severe obstructive sleep apnoea. METHODS: Patients were classified based on their obstructive apnoea hypopnoea index on initial polysomnogram, which was compared to their post-treatment polysomnogram. RESULTS: Eighteen patients underwent supraglottoplasty, and 12 patients had non-surgical treatment. The average obstructive apnoea hypopnoea index after supraglottoplasty fell by 12.68 events per hour (p = 0.0039) in the supraglottoplasty group and 3.3 events per hour (p = 0.3) in the non-surgical treatment group. Comparison of the change in obstructive apnoea hypopnoea index in the surgical versus non-surgical groups did not meet statistical significance (p = 0.09). CONCLUSION: All patients with laryngomalacia and obstructive sleep apnoea had a statistically significant improvement in obstructive apnoea hypopnoea index after supraglottoplasty irrespective of obstructive sleep apnoea severity, whereas patients who received non-surgical treatment had more variable and unpredictable results. Direct comparison of the change between the two groups did not find supraglottoplasty to be superior to non-surgical treatment. Larger prospective studies are recommended.

Airway Involvement and Intervention in Non-ACE-Inhibitor-Induced Angioedema.

OBJECTIVES: Characterize the presentation of patients with non-angiotensin-converting enzyme inhibitor (ACEI)-induced angioedema and determine risk factors associated with patient disposition and possible need for airway intervention. METHODS: The medical records of adult patients in the Emergency Department (ED) and diagnosed with non-ACEI-induced angioedema over 4.5 years were included. Demographics, vital signs, etiology, timeline, presenting symptoms, physical exam including flexible laryngoscopy, medical management, and disposition were examined. Statistical analyses were conducted using SPSS V 23.0 software calculating and comparing means, standard deviations, medians, and correlation of categorical and ordinate variables. RESULTS: A total of 181 patients with non-ACEI-induced angioedema were evaluated with flexible laryngoscopy by otolaryngology. Notably, 11 patients (6.1%) required airway intervention and were successfully intubated. Statistically significant factors (p ≤ 0.05) associated with airway intervention included the diastolic blood pressure (DBP) and mean arterial pressure (MAP) (p = 0.006 and 0.01 respectively), symptoms of dysphonia (p = 0.018), the presence of oropharyngeal, supraglottic, and hypopharyngeal edema (p ≤ 0.001 for each site), and the number of edematous anatomic subsites documented on physical exam (p < 0.001). Other patient demographics, prior history of angioedema, heart rate, systolic blood pressure, symptom onset, number of symptoms at presentation, and medication administered in the ED did not correlate with airway intervention. CONCLUSION: Dysphonia, DBP, MAP, anatomic location of edema and edema in multiple sites are associated with airway intervention and a higher level of care in non-ACEI-induced angioedema and can be useful in risk assessment in patient management.

Predictive Pediatric Characteristics for Revision Tonsillectomy After Intracapsular Tonsillectomy.

OBJECTIVES: There is little research on the rate and risk factors for revision tonsillectomy after primary intracapsular tonsillectomy. Our study aimed to determine the revision rate following intracapsular tonsillectomy, identify patient characteristics that may increase the probability of revision surgery, and report the tonsillar hemorrhage rate after revision. STUDY DESIGN: Level III, retrospective case-control study. SETTING: A tertiary care pediatric center (Alfred I. duPont Hospital for Children, Wilmington, Delaware). METHODS: A case-control study of pediatric patients who underwent intracapsular tonsillectomy between January 1, 2004, and December 31, 2018, was performed. Patients aged 2 to 20 years were analyzed and compared with matched controls who underwent intracapsular tonsillectomy within 7 days of the same surgeon's case. In total, 169 revision procedures were included with 169 matched controls. RESULTS: A 1.39% revision rate was observed among a total of 12,145 intracapsular tonsillectomies. Among the 169 patients who underwent a revision procedure, the mean time between cases was 3.5 years. Tonsillitis was the most common diagnosis prompting revision tonsillectomy. Four (2.4%) patients underwent operative control of a postoperative tonsillar hemorrhage after revision surgery. Younger patients (P < .001) and patients with a history of gastroesophageal reflux disease (P = .006) were more likely to undergo revision tonsillectomy. CONCLUSION: Patients below age 4 years and patients with gastroesophageal reflux disease may be at increased risk of undergoing revision tonsillectomy after primary intracapsular tonsillectomy. These factors should be considered when selecting an intracapsular technique for primary tonsillectomy in pediatric patients.

Geometric model to predict improvement after lingual frenulectomy for ankyloglossia.

OBJECTIVES: Frenulectomy for ankyloglossia is an intervention that often improves breastfeeding quality for both the mother and infant. Current classification systems assess and identify patients with ankyloglossia, but they do not predict the degree of improvement after lingual frenulectomy. We propose an idealized geometric model to quantify the potential effect of frenulectomy for ankyloglossia. METHODS: Our geometric model depicts the intact lingual frenulum as a triangular pyramid of mucosa on the floor of mouth. After incising one edge of the pyramid, as is performed during a frenulectomy, the structure unfolds to a two-dimensional diamond whose dimensions can be calculated. Utilizing this calculation, we can predict percent improvement in tongue extension after frenulectomy based off the original dimensions of the pyramid. RESULTS: Our multivariable equation that allows for the calculation of the percent increase in tongue extension is based on the frenulum thickness, frenulum length, tongue length, and insertion point of the frenulum on the tongue. The initial height of the frenulum and the proximity of the frenulum insertion to the tip of the tongue had the largest impact on tongue extension, whereas frenulum width had the smallest impact. CONCLUSION: Lingual frenulectomy has subjectively been reported to improve lingual tongue movement. Our mathematical model identifies multiple anatomic variables that lead to an increase in tongue extension after frenulectomy. Our model is the first step in supporting this subjective improvement with quantifiable measurements, and can allow for future validation studies.

Evaluating pediatric intensive care unit utilization after tonsillectomy.

OBJECTIVES: To identify patients at risk for a pediatric intensive care unit (PICU) level intervention after adenotonsillectomy. STUDY DESIGN: Retrospective cross-sectional study. SETTING: Tertiary Children's Hospital. SUBJECTS AND METHODS: Ninety-four patients who were admitted to the PICU after adenotonsillectomy were included. The need for PICU level intervention, defined as high flow oxygen by nasal cannula, positive airway pressure (PAP), heliox, and intubation, was documented. The age, gender, BMI percentile, polysomnography (PSG) data, home PAP use, and accompanying comorbidities of patients who required a PICU level intervention were compared to those who did not. RESULTS: Of the 94 patients admitted post-adenotonsillectomy to the PICU, most had at least one comorbidity, with obesity being the most common. PICU admission was unplanned in 29 (30.9%) patients. Postoperatively, 25 (26.5%) patients required a PICU level intervention, with PAP being the most common intervention. On chi-square analysis, there was no significant difference in the age, BMI percentile, or PSG parameters of children who required PICU intervention. Significantly more children who used preoperative PAP were started on PAP in PICU (p = 0.018). Only the comorbidity of neuromuscular disorder was associated with PICU intervention (p = 0.04). Using binary logistic regression, the use of home PAP and an oxygen nadir <80% on preoperative PSG were found to be independent predictors of PICU intervention (p = 0.04 and 0.025, respectively). CONCLUSION: Home PAP use, the presence of a neuromuscular disorder, and an oxygen nadir <80% on preoperative PSG is related to a PICU level intervention.

Post-transplant lymphoproliferative disease of the larynx.

Laryngeal post-transplant lymphoproliferative disease (PTLD) is rare. Here, we describe two pediatric cases. The first, a 15-month-old who underwent liver transplantation at 5 weeks, presented with airway distress. Airway evaluation identified epiglottic and arytenoid infiltrate, and biopsy was consistent with polymorphic PTLD. The second, a 23-month-old who underwent liver transplantation at 13 months, presented with progressive stridor. Airway evaluation revealed sub-mucosal infiltrate of the epiglottis, arytenoids, post-cricoid region, and uvula. Biopsy was consistent with monomorphic PTLD. Airway findings and symptoms resolved for both after immunosuppression reduction. PTLD diagnosis requires a high index of suspicion in post-transplant patients with airway obstruction.

Impact of Infant Supraglottoplasty on Quality of Life.

Objectives The objective of the present study is to examine the impact of supraglottoplasty on the quality of life (QOL) of caregivers and infants with severe laryngomalacia and moderate laryngomalacia with feeding difficulties. Study Design Prospective cohort study. Setting Tertiary children's hospital. Subjects and Methods Thirty-nine infants who underwent supraglottoplasty were examined. The primary caregiver answered the 47-item short form of the Infant and Toddler Quality of Life Questionnaire-47 pre- and postoperatively; the subsection scores were compared. A 1-way analysis of variance was performed to analyze the effect of age and sex. A comparison was made between our cohort and a general population of healthy children. Results The average age at surgery was 4.0 months, and 53% of the patients were male. There was significant postoperative improvement in overall health, physical ability, growth and development, bodily pain, temperament, emotional impact on the caregiver, impact on caregiver's time, and family cohesion scores ( P < .05). The same subscale scores remained significantly improved postoperatively after age and sex were controlled. Preoperative QOL scores were significantly worse than those of the general population in nearly all categories. Postoperative physical ability ( P = .009) and temperament ( P = .011) QOL scores were higher than the those of the general population. Scores for growth and development ( P = .132), bodily pain ( P = .481), and family cohesion ( P = .717) were equivalent to those of the general population. Conclusion QOL was significantly improved after supraglottoplasty for infants with severe laryngomalacia and moderate laryngomalacia with feeding difficulties. After supraglottoplasty, QOL was similar to that of the general infant population in most categories.

Mastoid and Inner Ear Measurements in Patients With Menière's Disease.

OBJECTIVE: To determine the relationship between radiographic temporal bone anatomy of patients with Menière's disease in medically and surgically managed populations versus controls. STUDY DESIGN: Retrospective chart review. SETTING: Two tertiary referral centers. PATIENTS: Adults older than 18 years with Menière's disease treated with endolymphatic sac decompression (ESD) or medical management (non-ESD) versus controls. INTERVENTIONS: Magnetic resonance imaging and computed tomography imaging studies of the temporal bones were reviewed by blinded radiologists. MAIN OUTCOME MEASURES: Radiographic temporal bone dimensions were measured in Menière's disease and control patients. Age, sex, symptoms, audiogram data, academy classification of Menière's disease, and follow-up were recorded. Statistical analysis was performed to compare outcome measures across groups and demographics. RESULTS: A total of 90 imaging studies were reviewed (ESD = 22; non-ESD = 30; control = 38). ESD and non-ESD groups had similar pure-tone averages (33.9 ±â€Š20.6 versus 41.6 ±â€Š22.6 dB HL; p = 0.21) and frequency of definite Menière's disease (59.1% versus 53.3%; p = 0.68). There was no significant trend between groups for any measurement. One nonsignificant trend existed in mean vestibule length, increasing from the control (5.45 ±â€Š0.54 mm), non-ESD (5.80 ±â€Š0.97 mm), and ESD (5.94 ±â€Š0.81 mm) group. In a combined Menière's group, mean vestibule length was significantly greater than controls (5.86 ±â€Š0.89 versus 5.45 ±â€Š0.54 mm; p = 0.008) and mean vestibule width significantly less (2.99 ±â€Š0.46 versus 3.19 ±â€Š0.39 mm; p = 0.024). CONCLUSION: Medical and surgical Menière's patients were similar utilizing academy classification. There was no significant trend between medical and surgical Menière's patients versus controls for any measurement. In a combined Menière's group, the longer and narrower vestibule anatomy may suggest an anatomical basis for endolymphatic hydrops.

Immunoglobulin G4-related sclerosing disease of the paranasal sinuses: A case report and literature review.

OBJECTIVE: Immunoglobulin G4 (IgG4) related sclerosing disease (RSD) of the paranasal sinuses is a rare lesion of dense lymphoplasmacytic tissue, with a high proportion of IgG4+ plasma cells. We presented a rare case of IgG4-RSD with isolated involvement of the paranasal sinuses in the absence of multiorgan involvement. METHODS: A case report and comprehensive literature review. RESULTS: To our knowledge, only 11 cases of IgG4-RSD with paranasal sinus involvement have been reported. Patients with IgG4-RSD commonly present with epistaxis and symptoms that mimic chronic rhinosinusitis, e.g., rhinorrhea, nasal obstruction, and facial pressure. On imaging, an expansive and erosive process is described. Surgery provides tissue for immunohistologic evaluation; however, there is a paucity of evidence about the direct extent of surgical resection or medical therapies. Postoperative steroids were typically started, although the regimen was not standardized. CONCLUSION: Few cases of paranasal sinus IgG4-RSD have been reported in the literature. Evidence-based recommendations regarding treatment and surveillance of paranasal sinus IgG4-RSD are lacking; however, most reports describe systemic steroids as the mainstay of treatment. This single subject analysis, with a review of previously reported cases adds to the expanding body of data related to this rare disorder.
