Timing of Tracheostomy in Critically Ill Infants and Children With Respiratory Failure: A Pediatric Health Information System Study.

OBJECTIVES: Tracheostomy placement in infants and children with respiratory failure has steadily increased over time, yet there is no consensus for optimal timing. We sought to: 1) describe tracheostomy timing and associated demographic and clinical characteristics in a large ICU cohort and 2) compare clinical outcomes between subgroups based on tracheostomy timing. DESIGN: Retrospective observational study using the Pediatric Health Information System (PHIS). SETTING: Neonatal ICUs and PICUs in the United States. PATIENTS: PHIS was queried for patients less than 18 years who underwent tracheostomy from 2010 to 2020. Patients were included if admitted to an ICU with need for mechanical ventilation (MV) prior to tracheostomy in the same hospitalization. Patients were categorized as early tracheostomy (ET) (placement at MV day ≤ 14), late tracheostomy (LT) (MV days 15-60), and extended tracheostomy (ExT) (MV day > 60). Primary endpoints included demographic and clinical characteristics. Secondary endpoints included patient outcomes: in-hospital mortality, length of stay (LOS), hospital-acquired pneumonia (HAP), and hospital costs. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Sixteen thousand one hundred twenty-one patients underwent tracheostomy at 52 children's hospitals. Ten thousand two hundred ninety-five had complete data and were included in the analysis. Thirty-nine percent (4,006/10,295) underwent ET, 40% (4,159/10,295) underwent LT, and 21% (2,130/10,295) underwent ExT. Majority of patients in all subgroups had complex chronic conditions. Median age was significantly different between subgroups with ET being the oldest ( p < 0.001). A multivariable regression analysis showed that ET was associated with lower in-hospital mortality ( p < 0.001), shorter hospital LOS ( p < 0.001), shorter ICU LOS ( p < 0.001), shorter post-tracheostomy LOS ( p < 0.001), decreased HAP ( p < 0.001), and lower hospital costs ( p < 0.001) compared with those who underwent LT or ExT. CONCLUSIONS: In a large cohort of pediatric patients with respiratory failure, tracheostomy placement within 14 days of MV was associated with improved in-hospital outcomes. ET was independently associated with decreased mortality, LOS, HAP, and hospital costs.

A Complicated Case of Congenital Nasal Pyriform Aperture Stenosis: Use of a Long-term Unilateral Nasal Stent.

This case describes a full-term baby with pyriform aperture stenosis who failed intranasal dexamethasone and reflux therapy. She underwent repair via a sublabial approach and inferior turbinate reduction. Symptoms initially improved but she was unable to be weaned from intranasal steroids. Three subsequent surgeries ensued, including lysis of synechiae, further turbinate reduction, and placement of custom nasal stents, which failed as they became clogged frequently and were easily dislodged, leading to increased intranasal manipulation and postprocedural inflammation. She was eventually fitted and discharged with a large, unilateral stent. After 8 weeks, the stent was removed; she was tolerating full oral feeds. This case highlights the limitations of surgical repair and describes nontraditional uses of stenting.

Management and outcomes of obstructive sleep apnea in infants.

OBJECTIVE: To characterize the clinical characteristics of infants with obstructive sleep apnea (OSA), define the resolution rate of infant OSA, and identify factors associated with OSA resolution. METHODS: We identified infants diagnosed with OSA via retrospective chart review at less than one year of age at a tertiary care center. We identified patient comorbidities, flexible or rigid airway evaluations, surgical procedures, and oxygen/other respiratory support administration. We identified infants as having resolved OSA based on clinical or polysomnogram resolution. We compared the frequency of comorbid diagnoses and receipt of interventions in infants with resolved versus non-resolved OSA by χ2 analysis. RESULTS: 83 patients were included. Prematurity was found in 35/83 (42%), hypotonia-related diagnoses in 31/83 (37%), and craniofacial abnormalities in 34/83 (41%). Resolution was observed in 61/83 (74%), either clinically or by polysomnogram, during follow up. On χ2 analysis, surgical intervention was not associated with likelihood of resolution (73% versus 74% in those without surgical intervention, p = 0.98). Patients with airway abnormalities on flexible or rigid evaluation were less likely to have OSA resolution than those without (63% versus 100%, p = 0.010), as were patients with hypotonia-related diagnoses (58% versus 83%, p = 0.014). In patients with laryngomalacia, there was no association of supraglottoplasty with increased resolution (88% with supraglottoplasty versus 80% without, p = 1.00). CONCLUSIONS: We identified a group of infants with OSA with diverse comorbidities. There was a high rate of resolution. This data can assist with treatment planning and family counselling for infants with OSA. A prospective clinical trial is needed to better assess consequences of OSA in this age.

Incidence of asymptomatic SARS-CoV-2 infection in children undergoing elective otolaryngologic surgery throughout the COVID-19 pandemic.

Objective: Children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are less clinically affected than adults, with most cases presenting as asymptomatic or mildly symptomatic. However, true rates of asymptomatic SARS-CoV-2 infection in children remain unclear. We sought to examine rates of SARS-CoV-2 in asymptomatic children and the role of children in transmission. Methods: We performed a retrospective review of patients between 6 months and 17 years of age who underwent elective or semi-elective otolaryngologic surgery with physicians affiliated with Weill Cornell Medicine between May 15, 2020 and March 31, 2022. Patients were included if they received molecular assay testing for SARS-CoV-2 without SARS-CoV-2 symptoms within 5 days of scheduled surgery. SARS-CoV-2 infection status, exposure, clinical symptoms, demographic data, and insurance status were recorded. Results: 1047 patients met inclusion criteria. Thirteen positive cases (1.24%) were identified in the study population. Six cases occurred between December 2021 and February 2022 following the classification of the omicron variant as a variant of concern in November 2021. Five of the 13 cases occurred in children under 2 years of age. Seven patients were male, and five were female. Residences spanned all five boroughs of New York City and the surrounding metropolitan area. Conclusion: Throughout the pandemic, children have had a low rate of asymptomatic disease and likely pose a low risk of transmission of SARS-CoV-2 to the general population. Our results suggest that testing of asymptomatic children is a low-yield practice that is unlikely to influence rates of SARS-CoV-2 in the general population. Level of Evidence: 3.

Tympanostomy tubes in the age of quarantine.

OBJECTIVES: After state-mandated COVID-19 quarantine measures were lifted in 2020, pediatric otolaryngologists noticed that many children who were previously scheduled for tympanostomy tube (TT) placement for indications of acute otitis media (AOM) or chronic middle ear effusions (OME) no longer required surgery. This study aims to describe the effect of home-quarantine on pediatric patients with recurrent AOM and OME to increase our understanding of these conditions. METHODS: This was a retrospective review of pediatric patients that were originally scheduled for TT for recurrent AOM and/or OME, but had their procedure cancelled due to COVID-19. The chi-square test was used to compare the proportion of patients who no longer met indications for surgery stratified by original indication. Data was also collected for TT volume in the months before and after the start of the pandemic. RESULTS: Of 59 patients originally scheduled for TT, 31.0% of the 42 patients who returned for follow-up still met indications for a procedure after a period of home-quarantine. Of these, 76.9% had persistent OME, 61.5% had recurrent AOM, and 69.2% had persistent conductive hearing loss. After elective surgery resumed, there was a substantial decrease in the number of TT procedures performed compared to pre-pandemic data. CONCLUSION: After a period of quarantine, many patients previously scheduled for TT experienced resolution of their AOM or OME. Despite a nationwide recovery in outpatient surgical volume across otolaryngology practices, TT volumes remain low one year after the start of the pandemic, suggesting that continued COVID-19 precautionary measures are contributing to this lingering effect.

Trends in outpatient intervention for pediatric ankyloglossia.

OBJECTIVES: Anecdotally, there has been an increase in ankyloglossia referrals and frenotomy procedures performed in recent years. Many studies have characterized frenotomy indications and outcomes, but none have quantified how the frequency of referrals and interventions have changed over time in the outpatient setting. This study analyzes temporal trends in the diagnosis and intervention of ankyloglossia in a pediatric otolaryngology practice to further clarify how patterns of management of this condition have changed over time. METHODS: This study was a retrospective chart review of patients evaluated for ankyloglossia in an outpatient pediatric otolaryngology clinic between 2008 and 2018. The chi-square test for trend was used to assess yearly changes in the referral numbers, surgical interventions, and procedure indication prevalence proportions of interest. RESULTS: Referral numbers and frenotomy procedures increased as a percentage of total office visits from 2008 to 2018 (P = 0.0026, P < 0.0001). The trend in frenotomies was especially pronounced in the 0 to 2-month age group (P < 0.0001) but was not observed in the 2 months to 1-year (P = 0.30) or 1- to 4-year (P = 0.40) age groups. Frenotomy performed for concerns of feeding (P < 0.0001) increased over the study period, but there was no significant increase in procedures performed for speech concerns (P = 0.13). CONCLUSION: Significant increases in referrals for frenotomy and number of frenotomy procedures performed are demonstrated, especially in young infants for feeding concerns. It is unlikely representative of a true increase in the incidence of ankyloglossia, but rather the result of cultural and clinical factors driving referrals and intervention.

Iatrogenic Cushing's syndrome and adrenal insufficiency in infants on intranasal dexamethasone drops for nasal obstruction - Case series and literature review.

The use of intranasal steroid drops for nasal obstruction in infants is common practice and can prevent more invasive surgical procedures; however, it is not without complication. We describe 2 cases of iatrogenic Cushing's secondary to nasal steroids in infants with nasal obstruction, discuss the etiology of this unusual complication, and review previous literature reports. While reporting in the literature is sparse, these cases highlight the risk of development of adrenal insufficiency with usage of nasal steroid drops in infants as well as the need for close monitoring of administration and tapering of the drops. Additionally, we suggest an approach to the infant with symptomatic nasal obstruction that addresses the usage of intranasal steroid drops and emphasizes the need for quick tapering and possible endocrine consultation when appropriate.

Pediatric tracheal tumor masked by a history of travel: case report and literature review.

A previously healthy 10-year-old female reported a 1-month history of wheezing and hemoptysis. Initial evaluation and treatment were focused on refractory reactive airway disease and infectious etiologies prompted by her recent travels in Africa. Worsening respiratory distress prompted emergent evaluation with imaging and endoscopy. Bronchoscopy diagnosed a distal tracheal tumor; pathology of this tumor was benign fibrous histiocytoma. Successful management of this condition included imaging, rigid bronchoscopy with biopsy, and tracheal resection to surgically excise the lesion. Although rare, tracheal tumors should be considered when presentation of asthma is atypical and nonresponsive to medical interventions.

A comparative analysis of open surgery vs endoscopic balloon dilation for pediatric subglottic stenosis.

IMPORTANCE: Minimally invasive endoscopic techniques are an appealing alternative to open surgical management of pediatric subglottic stenosis (SGS), but more information is needed to understand the comparative risks, benefits, and limitations of such interventions. OBJECTIVE: To compare the effectiveness of endoscopic balloon dilation (EBD) and laryngotracheoplasty (LTP) in pediatric patients with SGS and to identify patient and disease factors that are associated with successful EBD. DESIGN, SETTING, AND PARTICIPANTS: A retrospective medical record review of children undergoing EBD and LTP for SGS in a tertiary care children's hospital from 2006 through 2012. MAIN OUTCOMES AND MEASURES: Success was defined as decannulation or tracheotomy avoidance. Additional outcomes were total number of procedures and number of unplanned procedures. Univariate χ2 analyses and multivariate regression analyses were performed to identify patient and disease factors statistically associated with success within treatment groups. RESULTS: Overall, 86 of 90 patients (96%) successfully avoided tracheotomy or were decannulated. Fourteen patients were successfully treated with EBD, but for 13 patients, EBD failed, and they underwent LTP. A total of 76 patients underwent LTP. In univariate analyses, patients for whom EBD was successful were more likely to have mild (grade 1 or 2; n = 10) than severe (grade 3 or 4; n = 4) SGS compared with patients for whom EBD failed (grade 1 or 2, n = 0 vs grade 3 or 4, n = 13) (P < .001). Three patients who underwent initial EBD had worsening stenosis. Patients initially treated with EBD were more likely to require unplanned surgical intervention during their treatment (6 of 27; 22%) than patients initially treated with LTP (3 of 63; 5%) (P = .01). Patients initially treated with EBD had a lower number of airway interventions and/or evaluations under anesthesia (mean, 6.7) during their course of treatment than patients initially treated with LTP (mean, 9.2) (P = .003). In multivariate analyses, only severe SGS was significantly associated with failure of initial EBD (13 of 13 [100%] with type 3 or 4 vs 4 of 14 with type 1 or 2 [29%]) (P = .002). CONCLUSIONS AND RELEVANCE: For severe SGS, EBD has limited application compared with LTP, and in some cases failed EBD is even detrimental, increasing the risk of unplanned urgent interventions compared with LTP.

Barriers to early pediatric cochlear implantation.

OBJECTIVES: Universal newborn hearing screening has significantly improved the ability to identify patients with congenital sensorineural hearing loss (SNHL), which results in earlier treatment and better hearing and development outcomes. It is recommended that patients born with SNHL who meet criteria receive cochlear implants (CIs) by a target age of 12 months, however many children are being implanted at an older age. This study aims to describe populations of pre-lingual patients with SNHL that are at risk for delayed implantation and to identify and analyze barriers that cause this delay. METHODS: Charts of patients receiving a CI between January 2008 and June 2012 at a tertiary care cochlear implant center were reviewed retrospectively. We looked at patient demographics, age at hearing loss diagnosis, age at implantation, and etiology of hearing loss. Barriers to implantation were identified through surveys completed by team members. RESULTS: Fifty-seven CI recipients were identified of which 42 were in patients with pre-lingual SNHL. SNHL etiology included: cochlear dysplasia (18%), GJB2/GJB6 (17%), acquired (10%) extreme prematurity (9%), and idiopathic (46%). The median age of SNHL diagnosis for pre-lingual patients was 15 months. Compared to private insurance, public insurance status was associated with SNHL diagnosis at a significantly later median age (20.0 vs. 4.0 months, p=0.024), and with a significantly longer median interval from diagnosis to implantation (25.5 vs. 11.0 months, p=0.029). While cochlear implant team members identified delayed insurance approval and medical comorbidities as reasons for delayed implantation, the most significant factor identified was parental, with delayed/missed appointments or reluctance for evaluations or surgery. CONCLUSION: 52% of patients with pre-lingual SNHL that met criteria for CI were implanted more than 12 months after diagnosis. Having public or no insurance was significantly associated with delayed implantation. Parental barriers were most common factors cited for delays in implantation. Overcoming these delays necessitates appropriate identification of at risk patients and creating a system to educate families and chaperone them through the process.

Sialoendoscopy in the diagnosis and management of obstructive sialadenitis.

OBJECTIVE: Sialoendoscopy is a new technology being used at a limited number of institutions for the diagnosis and management of obstructive sialadenitis. This technique is promising for its superior diagnostic potential as well as its decreased morbidity compared to traditional more invasive techniques for managing obstruction. Our objective is to review the sialoendoscopy experience at our institution to identify successes, areas of improvement, and to provide guidance to other programs that may be interested in sialoendoscopy. STUDY DESIGN: We did a retrospective review of all diagnostic and interventional sialoendoscopies performed at this institution from 2007 to 2009. METHODS: Charts were reviewed for epidemiologic and clinical data, as well as procedural techniques, findings, and outcomes. RESULTS: We attempted 37 parotid and submandibular sialoendoscopies, with successful endoscopic canalization of the duct in 36 of these cases. Twenty of 25 stones were removed from 18 patients. Stones that were larger than 5 mm were more difficult to dislodge and remove without fragmentation. Other abnormal findings included strictures, scars, and mucoid debris. There were two failures of technique, and two patients had postoperative purulent sialadenitis that resolved after antibiotics. CONCLUSIONS: As an institution that recently began performing sialoendoscopies, we show similar success rates compared to other programs. Obstacles included the initial cost of acquiring equipment and the associated learning curve of using a new technique. Similar to other programs, successful extraction of sialoliths was limited with larger stones. In the future, we hope to use laser lithotripsy for fragmentation, a technique already being trialed at some institutions.

Using surgical observations of ossicular erosion patterns to characterize cholesteatoma growth.

OBJECTIVE: To describe and quantify growth patterns of cholesteatomas within the middle ear using a scaled rating system that characterizes patterns of ossicular erosion. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Patients undergoing first-time surgery for primary and secondary acquired cholesteatomas. INTERVENTIONS: Intraoperative assessments of ossicular destruction by cholesteatoma growth were performed. MAIN OUTCOME MEASURES: A scaled system was created to classify the degree of erosion for each ossicle. Ossicular destruction patterns were quantified and compared. RESULTS: A total of 157 ears of 152 patients with cholesteatomas, who met our inclusion criteria, were operated on by the senior author (S.H.S.) between 1992 and 2009. The incus was the most significantly affected ossicle, whereas the stapes was the most variably affected ossicle. The most commonly represented ossicular erosion patterns for primary acquired cholesteatomas demonstrated an intact malleus abutting cholesteatoma, erosion of the incus, and minimal stapes involvement, whereas the common erosion patterns for secondary acquired cholesteatomas demonstrated intact malleus abutting cholesteatoma, erosion of the incus, and erosion of the stapes. CONCLUSION: Previous assessments of ossicular destruction by cholesteatomas were largely created for staging purposes and for guiding surgical reconstruction. Minimal information can be obtained from these data that both describe and quantify cholesteatoma growth patterns. Our ossicle categories more completely described how erosion develops using a scaled system. Common erosion patterns for both primary acquired and secondary acquired cholesteatomas validate anatomic studies and observations of how middle ear anatomy and compartment boundaries guide cholesteatoma growth.

Principles of glomerular organization in the human olfactory bulb--implications for odor processing.

Olfactory sensory neurons (OSN) in mice express only 1 of a possible 1,100 odor receptors (OR) and axons from OSNs expressing the same odor receptor converge into approximately 2 of the 1,800 glomeruli in each olfactory bulb (OB) in mice; this yields a convergence ratio that approximates 2:1, 2 glomeruli/OR. Because humans express only 350 intact ORs, we examined human OBs to determine if the glomerular convergence ratio of 2:1 established in mice was applicable to humans. Unexpectedly, the average number of human OB glomeruli is >5,500 yielding a convergence ratio of approximately 16:1. The data suggest that the initial coding of odor information in the human OB may differ from the models developed for rodents and that recruitment of additional glomeruli for subpopulations of ORs may contribute to more robust odor representation.
