Systemic Bevacizumab for Treatment of Respiratory Papillomatosis: International Consensus Statement.

OBJECTIVES/HYPOTHESIS: The purpose of this study is to develop consensus on key points that would support the use of systemic bevacizumab for the treatment of recurrent respiratory papillomatosis (RRP), and to provide preliminary guidance surrounding the use of this treatment modality. STUDY DESIGN: Delphi method-based survey series. METHODS: A multidisciplinary, multi-institutional panel of physicians with experience using systemic bevacizumab for the treatment of RRP was established. The Delphi method was used to identify and obtain consensus on characteristics associated with systemic bevacizumab use across five domains: 1) patient characteristics; 2) disease characteristics; 3) treating center characteristics; 4) prior treatment characteristics; and 5) prior work-up. RESULTS: The international panel was composed of 70 experts from 12 countries, representing pediatric and adult otolaryngology, hematology/oncology, infectious diseases, pediatric surgery, family medicine, and epidemiology. A total of 189 items were identified, of which consensus was achieved on Patient Characteristics (9), Disease Characteristics (10), Treatment Center Characteristics (22), and Prior Workup Characteristics (18). CONCLUSION: This consensus statement provides a useful starting point for clinicians and centers hoping to offer systemic bevacizumab for RRP and may serve as a framework to assess the components of practices and centers currently using this therapy. We hope to provide a strategy to offer the treatment and also to provide a springboard for bevacizumab's use in combination with other RRP treatment protocols. Standardized delivery systems may facilitate research efforts and provide dosing regimens to help shape best-practice applications of systemic bevacizumab for patients with early-onset or less-severe disease phenotypes.

Routine pathologic examination of tonsillectomy specimens: A 10-year experience at a tertiary care children's hospital.

OBJECTIVE: To review histopathologic diagnoses from tonsillectomy specimens and determine whether routine pathologic exam is necessary. METHODS: Pathology reports of patients undergoing tonsillectomy from 2005 to 2014 at our pediatric tertiary care hospital were reviewed. Histopathologic diagnoses were recorded with special attention to identification of malignancy. RESULTS: A total of 8807 paired tonsil specimens were sent to pathology over a 10-year course. Gross analysis was performed on all. Microscopic histopathologic analysis was performed on 612 (6.95%) specimens with all but one demonstrating strictly reactive lymphoid hyperplasia. The single specimen (0.16%) demonstrated follicular hyperplasia with focal necrotizing granulomatous lymphadenitis without organisms identified on special staining. The surgeon requested pathologic diagnosis to rule out lymphoma in 4 of 8087 (0.05%) of the specimens. No malignancies were identified. The approximate charges for gross examination of a paired tonsillectomy specimen and microscopic examination were $136.10 and $294.54, respectively. Over the 10 year period of the study, total charges were estimated at $1,115,340 (gross) and $180,258 (microscopic). DISCUSSION: Microscopic analysis of tonsil specimens is unlikely to identify abnormal pathology that changes patient management. This study suggests that neither gross nor microscopic pathologic examination of tonsillectomy specimens is necessary on a routine basis. Histologic analysis of tonsils should be requested only on a case by case basis when clinical suspicion for malignancy is high. Avoiding routine pathologic exam of tonsils may be cost effective and medically safe.

The otolaryngologist's role in newborn hearing screening and early intervention.

Infant hearing loss is common. Screening is performed in more than 98% of US infants. Otolaryngologists play an important role in identification and management of infants and children who are deaf and hard of hearing. Otolaryngologists should routinely assess for hearing screening results and intervene for screens not passed. Long-term follow-up and reassessment of patients with hearing loss is an ongoing component of otolaryngology practice. This article reviews the otolaryngologist's role in the management of infants and children who are deaf or hard of hearing from screening to intervention and management.

Enhanced tracheostomy wound healing using maltodextrin and silver alginate compounds in pediatrics: a pilot study.

BACKGROUND: Tracheostomy wounds are commonly encountered in children but rarely reported. Relatively few treatments are available or have been investigated to manage this problem. Healing times for pediatric tracheostomy wounds are often unpredictable and protracted. Recent use of maltodextrin gel (MD) and a silver alginate sponge (AG) at our institution has demonstrated expedited healing and interest in this novel treatment for tracheostomy wounds. METHODS: We conducted an 11-month retrospective review of children with wound complications following tracheostomy placement at a tertiary care facility. Wounds were evaluated and rated based upon the National Pressure Ulcer Advisory Panel staging system. Subjects identified with stage 2 or greater tracheostomy-related ulcers treated with MD and/or AG were included. Subject characteristics and wound healing rates were tabulated in a database that included age, wound site, initial and final wound stage, type of treatment, length of treatment, and complications. Tracheostomy wounds treated as an out-patient were excluded from the study. RESULTS: Eighteen subjects, which included both in-patients and out-patients, were treated with AG and/or MD during the study period for tracheostomy-related wounds. Of the 26 subjects with tracheostomies performed during the study period, 10 (38.5%) were treated for postoperative wounds. A total of 11 subjects completed their in-patient wound treatment and were thus included in the study. Average subject age was 5.3 y (range 0.25-15.6 y). Wound locations were as follows: infrastomal region (n = 8), stoma (n = 2), and lateral neck (n = 1). Six subjects had stage 2 wounds, 4 had stage 3 wounds, and 1 had a stage 4 ulcer. All wounds achieved complete epithelialization following treatment with MD and/or AG. The average length of treatment was 12.8 d (range 6-28 d). No adverse effects were identified. CONCLUSIONS: Postoperative tracheostomy wounds are common. The use of MD and AG provides an effective and safe treatment for tracheostomy-related ulcers.

Supraglottoplasty outcomes in neurologically affected and syndromic children.

IMPORTANCE: Supraglottoplasty (SGP) failure is frequently attributed to coexistent medical comorbidities, but studies specifically evaluating outcomes in these populations are lacking. OBJECTIVE: To assess SGP outcomes in patients with neurologic and syndromic comorbidities and severe laryngomalacia (LM). DESIGN, SETTING, AND PARTICIPANTS: Case series with retrospective review of medical records of 54 patients with neurologic and/or syndromic comorbidity and severe LM who underwent SGP between 2004 and 2012 at a tertiary care pediatric institution. INTERVENTIONS: Patients presented with severe LM that required SGP. Supraglottoplasty failure necessitated revision SGP, tracheostomy, or gastrostomy tube insertion, or LM and obstructive sleep apnea that required assisted ventilation (continuous positive airway pressure and bilevel positive airway pressure). MAIN OUTCOMES AND MEASURES: Medical records were reviewed with a focus on patient factors, surgical timing, complications, and surgical and dysphagia outcomes. Patients were grouped based on their age at the time of SGP as infants (aged ≤12 months) and children (aged >12 months). Statistical comparisons were performed with SGP outcomes of infants with LM and no comorbidities. RESULTS: Fifty-four patients met the inclusion criteria. Thirty-one (13 infants, 18 children) had a neurologic condition and 23 (15 infants, 8 children) had syndromes. The overall success rate of SGP was 67% (36 of 54) in these populations. Neurologic (P = .003) and syndromic (P < .001) comorbidities were associated with significant reduction in SGP success rates vs no comorbidities. Among SGP failures (18 of 54 [33%]), 13% (7 of 54) required tracheostomy, 9% (5 of 54) needed assisted ventilation, 7% (4 of 54) required a postoperative gastrostomy tube, and 4% (2 of 54) required revision SGP. In the neurologic comorbidities group, patients with cerebral palsy had significantly higher tracheostomy rates compared with those who had other neurologic pathologies constituting comorbidities (2 of 11 [18%] vs 0 of 20; P = .049). In infants, acute airway obstruction was the most common indication for SGP in the neurologically comorbidity and syndrome populations (success rates, 69% and 67%, respectively). In children, obstructive sleep apnea was the most common indication for SGP in the neurologic comorbidity and syndrome populations (success rates, 78% and 50%, respectively). CONCLUSIONS AND RELEVANCE: Supraglottoplasty remains useful and outcomes were better in patients with neurologic comorbidity than in patients with syndromic comorbidity.

Prospective quality of life assessment in congenital laryngomalacia.

PURPOSE OF STUDY: Disturbances in breathing or feeding may profoundly affect parental perceptions of a newborn's health. Previous research into quality of life for patients with laryngomalacia is limited to retrospective analysis. The purpose of this study is to prospectively evaluate the quality of life of families of infants with laryngomalacia and the impact of surgical and non-surgical treatments. DESIGN AND METHOD: Pilot prospective analysis using the laryngomalacia quality of life (QOL) survey in families of infants with newly diagnosed laryngomalacia under age one year. A 29-question survey regarding severity of symptoms related to overall health, airway, and swallowing is completed at initial and post-treatment visits. Responses are quantified over a range from 1 to 5 (1 never to 5 always). RESULTS: Twenty-six families were enrolled in the study. Eleven patients were managed medically and fifteen underwent supraglottoplasty. The overall mean QOL score for patients treated medically was 2.57 (standard error, SE 0.16) on initial visit and 1.67 (SE 0.16) post-treatment (mean 3.9 months). Patients undergoing supraglottoplasty had an overall mean QOL score of 3.59 (SE 0.14) on initial visit and 2.22 (SE 0.22) post-treatment (mean 3.5 months). Analysis of variance (ANOVA) and post hoc testing revealed significant improvement between initial and follow-up visits in both treatment groups (p < 0.01). Patients who underwent supraglottoplasty had significantly higher scores at initial visit (p < 0.01). No statistically significant difference was noted between patient groups post-treatment (p > 0.05). CONCLUSIONS: Prospective QOL assessment of children with laryngomalacia and their families reveals a significant burden of disease. Quality of life improves in all patients but may improve more significantly in patients managed surgically.

Supraglottoplasty in premature infants with laryngomalacia: does gestation age at birth influence outcomes?

PURPOSE: Prematurity is thought to be to be an independent risk factor for supraglottoplasty (SGP) failure. The purpose of this study was to compare the outcomes of supraglottoplasty in premature infants with congenital laryngomalacia (LM) with that of term infants. STUDY DESIGN: Case series with chart review. SETTING: Tertiary-care pediatric institution. METHODS: Analysis was performed on 325 consecutive patients undergoing SGP between 2004 and 2012. Patients older than 12 months age or with syndrome, neurologic, or cardiac comorbidities were excluded. Resolution of airway symptoms after SGP was considered successful while revision SGP and tracheostomy were considered failures. The rates of secondary airway lesions (SAL), dysphagia, and gastrostomy tube (GT) placement were also compared. RESULTS: A total of 176 infants (136 term, 40 preterm) were identified. SGP was successful in 92.7% term and 90% preterm infants with no significant difference (P = .5865). Incidence of revision SGP and tracheostomy was similar among the groups. The outcomes of SGP were the same in all groups stratified by age. Incidence of SAL was significantly higher in preterm (72.5%) compared to term infants (34.6%, P = .0002). Dysphagia rates in the follow-up were higher in preterm (32.5%) versus term infants (6.6%, P < .001). The rate of GT insertion was significantly greater (P = .003) in preterm (27.5%) than term infants (6.6%). The preoperative dysphagia, persistent dysphagia, and GT in follow-up was significantly higher when gestation age <32 weeks (25%, P = .0168). CONCLUSION: Supraglottoplasty outcomes in term and preterm infants were similar irrespective of gestation age. Higher rates of dysphagia in follow-up are seen when gestation age <32 weeks.

Submucosal nerve hypertrophy in congenital laryngomalacia.

OBJECTIVES/HYPOTHESIS: To determine the neuropathologic findings in tissue obtained from children with laryngomalacia at a tertiary-care pediatric hospital. STUDY DESIGN: Retrospective review of consecutive cohort compared with a control group. METHODS: We reviewed supra-arytenoid pathology specimens from 43 children with severe laryngomalacia and 13 age-matched pediatric autopsy controls. Histopathologic comparison was made of nerve hypertrophy (including nerve perimeter and surface area) among experimental and control pathologic specimens. RESULTS: There exists a statistically significant increase in nerve perimeter (P = .001) and nerve surface area (P = .02) in supra-arytenoid specimens in patients with severe laryngomalacia compared with age-matched autopsy supra-arytenoid tissue. CONCLUSIONS: The pathologic finding of nerve hypertrophy in children with laryngomalacia provides new evidence to support neurologic dysfunction as the etiologic theory of laryngomalacia.

Accuracy and safety of tracheoscopy for infants in a tertiary care clinic.

OBJECTIVE: To assess the diagnostic accuracy and safety of office-based tracheoscopy when combined with flexible fiberoptic laryngoscopy (FFLT). Flexible laryngoscopy on infants is routinely performed by otolaryngologists in the clinic. The addition of tracheoscopy may improve overall airway assessment but is rarely performed due to the suspected risk of airway compromise. DESIGN: A 6-year retrospective medical record review. SETTING: Tertiary care hospital. PATIENTS: Thirty-one infants younger than 1 year with complete data from preoperative FFLT and microlaryngoscopy and bronchoscopy (MLB) were examined. MAIN OUTCOME MEASURES: Results from 241 MLB procedures were reviewed. RESULTS: Laryngomalacia (LM) and tracheomalacia (TM) were identified more often by FFLT than by MLB. In particular, the detection rate for LM and TM by MLB, as seen preoperatively by FFLT, was 79% and 61%, respectively. Compared with FFLT, MLB accurately diagnosed the severity of LM and TM only 55% and 65%, respectively, of the time. Fiberoptic laryngoscopy revealed synchronous airway lesions in 62% of infants with LM, while MLB discovered synchronous airway lesions in 54%. Static airway lesions were more frequently diagnosed with MLB. No respiratory events occurred during FFLT. CONCLUSIONS: In an appropriate patient, FFLT is a safe and effective diagnostic tool for common infant tracheal and laryngeal abnormalities. Detection and characterization of dynamic airway lesions is better achieved by FFLT than by MLB.
