Bronchopulmonary dysplasia and ventilation-associated outcomes after pediatric tracheostomy.

OBJECTIVES: The objective of this study is to determine the time to ventilator liberation and decannulation after tracheostomy placement in children with bronchopulmonary dysplasia (BPD) and pulmonary hypertension. METHODS: A prospective cohort study included all children (<18 years old) who underwent tracheostomy between 2015 and 2021 with or without a diagnosis of BPD. The primary outcomes were time to ventilator liberation, tracheostomy decannulation, or death with tracheostomy in place. RESULTS: A total of 303 children met inclusion with a median (interquartile range [IQR]) age at tracheostomy of 6.9 (IQR: 4.0-49.5) months. A diagnosis of BPD was made for 42% (N = 127) and this group was younger (5.1 vs. 24.5 months, p < .001) and more often had pulmonary hypertension (68% vs. 24%, p < .001). Children with BPD spent a median of 2.9 years (IQR: 1.6-4.0) on ventilation compared to 1.9 years (IQR: 0.9-3.7) for children without BPD (p = .009). The time to decannulation was greater among children with BPD (3.4 vs. 1.8 years, p < .001). However, unadjusted estimates of ventilator liberation (hazard ratio [HR]: 1.05, 95% confidence interval [95% CI]: 0.77-1.44) and decannulation (HR: 1.11, 95% CI: 0.74-1.66) over time were not prolonged by BPD. Pulmonary hypertension was associated with shorter time to death (adjusted HR [aHR] = 1.99, 95% CI: 1.17-3.38, p = .01), while BPD was associated with longer time to death (aHR: 0.38, 95% CI: 0.22-0.67, p = .001). CONCLUSION: BPD is associated with increased ventilation and duration of tracheostomy but over time many children with BPD will wean off the ventilator and be decannulated. Pulmonary hypertension and not BPD is associated with increased time to death after tracheostomy.

Postoperative Respiratory Complications After Adenotonsillectomy in Children With High-Risk Obstructive Sleep Apnea.

OBJECTIVE: Identify patient characteristics and polysomnogram (PSG) parameters associated with postoperative respiratory complications after adenotonsillectomy (AT) among children with high-risk obstructive sleep apnea (OSA). STUDY DESIGN: Case series with chart review. SETTING: Tertiary care children's hospital. METHODS: Pediatric patients (<18 years) with high-risk OSA (any 1 of: apnea-hypopnea index [AHI] >30, O2 nadir <80% and peak CO2 >60 mm Hg) on overnight PSG from 2019 to 2021 were included. Primary outcomes were major respiratory intervention during the postoperative admission, prolonged hospitalization, and intensive care unit (ICU) stay. RESULTS: A total of 307 patients met inclusion criteria. Median age was 6.5 years and 63% were male. Twenty-five (8.1%) required major respiratory intervention and 29 (9.7%) required ICU admission after AT. Major interventions and ICU admissions were significantly associated with neuromuscular disease (P < .01), higher obstructive apnea-hypopnea index (oAHI), higher CO2 peak, and lower O2 nadir. Prolonged admission had similar findings except oAHI was not significantly associated. Younger children were significant more likely to require ICU admission or prolonged admission. CONCLUSION: Increased oAHI and worsening O2 and CO2 parameters on preoperative PSG were associated with postoperative respiratory complications in children with high-risk OSA. Children with neuromuscular disease and age 0 to 2 had higher risk of ICU stay and prolonged hospitalization. Clinicians should recognize the importance of parameters beyond oAHI when anticipating postoperative monitoring.

Subglottic Stenosis After Pediatric Tracheostomy.

OBJECTIVES: To determine the incidence of subglottic stenosis (SGS) in children after tracheostomy and identify risk factors for development. STUDY DESIGN: Retrospective cohort. METHODS: All patients (<18 years) undergoing tracheostomy at a tertiary children's hospital between 2015 and 2020 were included. Patients with a direct laryngoscopy (DL) concurrent with tracheostomy and a subsequent DL were included. Medical records, including operative reports, were reviewed to identify subglottic stenosis and associated risk factors. RESULTS: A total of 140 patients were included with mean age at tracheostomy of 2.4 years (standard deviation [SD]: 4.3) (median: 0.5 years, interquartile range [IQR]: 0.3-1.5 years) and gestational age of 33.8 weeks (SD: 5.9) (median: 36 weeks, IQR: 28-39 weeks). At initial DL, 24% (N = 34) had subglottic injury and 26% (N = 37) developed SGS. The incidence of SGS after tracheostomy was 11.5 cases per 100 patients per year. At tracheostomy, lower birth weight (1.8 vs. 2.3 kg, p = 0.005), shorter gestational age (31.8 vs. 34.6 weeks, p = 0.01), younger age (0.8 vs. 2.9 years, p = 0.01), lower weight (5.8 vs. 14.7 kg, p = 0.01), and subglottic injury (44% vs. 21%, p = 0.01) were associated with the development of SGS. Multivariable logistic regression analysis associated birth weight (odds ratio [OR]: 0.49, 95% confidence interval [CI]: 0.31-0.75, p = 0.001) and early subglottic injury (OR: 3.22, 95% CI: 1.31-7.88, p = 0.01) with SGS development. CONCLUSIONS: The incidence of SGS after pediatric tracheostomy is estimated at 11.5 cases per 100 patients per year. Low birth weight and subglottic injury at the time of tracheostomy were associated with SGS in this vulnerable population of children. LEVEL OF EVIDENCE: 3 Laryngoscope, 2024.

Evaluation of Pediatric Posterior Glottic Diastasis Using Dynamic Voice Computed Tomography.

OBJECTIVES: Posterior glottic diastasis (PGD) is an underappreciated etiology of dysphonia in patients with prior airway reconstruction or prolonged intubation. In endoscopic posterior cricoid reduction (ePCR), cricoid is removed to minimize the posterior glottic gap. Dynamic voice computed tomography (DVCT) permits visualization of the posterior glottis, estimating the amount of cricoid to be removed. Posterior glottic gaps in patients undergoing ePCR were compared to non-dysphonic patients to describe pediatric PGD and establish surgical parameters for ePCR. METHODS: DVCTs performed in non-dysphonic patients and dysphonic patients undergoing ePCR from 2014 to 2023 were reviewed. EPCR operative reports were queried. Pre- and postoperative Pediatric Voice Handicap Index (pVHI) and Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) scores and aerodynamic measures were reviewed. RESULTS: Seventeen pediatric patients who underwent ePCR and 19 non-dysphonic patients were included. Posterior glottic gaps were significantly larger in the dysphonic group (median 2.4 mm [IQR: 2.0, 2.8] vs. 1.3 mm [IQR: 1.1, 1.7], p < 0.001). Mean width of the cricoid removed was 1.6 mm (SD 0.4 mm). Mean (SD) pre- and postoperative pVHI scores were 55.5 (19.9) and 34.6 (16.0; p < 0.001). Mean (SD) pre- and postoperative CAPE-V scores were 52.7 (15.4) and 36.5 (20.4; p < 0.001), respectively. CONCLUSIONS: Children in this cohort tolerated an average 1.3 mm posterior glottic gap without dysphonia. Dysphonic patients with PGD had a median 2.4 mm gap and underwent cricoid reduction by 1.6 mm. All ePCR patients demonstrated improvement in dysphonia. Results seek to optimize the management of pediatric PGD and present a safe and effective amount of cricoid to remove during ePCR. LEVEL OF EVIDENCE: 4 Laryngoscope, 2024.

Injection Laryngoplasty for Children with Dysphagia after Cardiac Surgery.

Objective: To determine whether injection laryngoplasty (IL) resolves thin liquid aspiration among children with unilateral vocal cord paralysis (UVCP) after cardiac surgery. Study Design: Retrospective case-control. Setting: Tertiary children's hospital. Methods: Consecutive children (<5 years) between 2012 and 2022 with UVCP after cardiac surgery were included. Resolution of thin liquid aspiration after IL versus observation was determined for children obtaining videofluoroscopic swallow studies (VFSS). Results: A total of 32 children with left UVCP after cardiac surgery met inclusion. Initial surgeries were N = 9 (28%) patent ductus arteriosus ligations, N = 7 (22%) aortic arch surgeries, N = 9 (28%) surgeries for hypoplastic left heart syndrome, and N = 7 (22%) other cardiac surgeries. The mean age at initial surgery was 1.8 months (SD: 3.7). All children had a VFSS obtained after surgery that confirmed aspiration. There were 17 children that obtained an IL at 33.6 months (SD: 20.9) after cardiac surgery and 15 children observed without IL procedure. No surgical complications after IL were noted. The rate of aspiration resolution based on postoperative VFSS was N = 14 (82%) for the IL group and N = 9 (60%) for the control group P = .24. Documented VFSS aspiration resolution after cardiac surgery occurred by 9.6 months (SD: 10.0) in the observation group and 47.4 months (SD: 24.1) in the IL group (P < .001). Conclusion: IL can help treat aspiration in children with UVCP after cardiac surgery but the benefit beyond observation remains unclear. Future studies should continue to explore the utility for IL in managing dysphagia in this pediatric population.

Tracheal A-frame deformity and suprastomal collapse after pediatric tracheostomy.

Objectives: To determine the incidence of A-frame deformity and suprastomal collapse after pediatric tracheostomy. Study design: Retrospective cohort. Methods: All patients (<18 years) that had a tracheostomy placed at a tertiary institution between 2015 and 2020 were included. Children without a surveillance bronchoscopy at least 6 months after tracheostomy were excluded. Operative reports identified tracheal A-frame deformity or suprastomal collapse. Results: A total of 175 children met inclusion with 18% (N = 32) developing A-frame deformity within a mean of 35.8 months (SD: 19.4) after tracheostomy. For 18 children (18/32, 56%), A-frame developed within a mean of 11.3 months (SD: 15.7) after decannulation. There were 96 children developing suprastomal collapse (55%) by a mean of 17.7 months (SD: 14.2) after tracheostomy. All suprastomal collapse was identified prior to decannulation. Older age at tracheostomy was associated with a lower likelihood of collapse (OR: 0.92, 95% CI: 0.86-0.99, p = .03). The estimated 5-year incidence of A-frame deformity after tracheostomy was 32.8% (95% CI: 23.0-45.3) and the 3-year incidence after decannulation was 36.1% (95% CI: 24.0-51.8). Highly complex children had an earlier time to A-frame development (p = .04). At 5 years after tracheostomy, the estimated rate of suprastomal collapse was 73.7% (95% CI: 63.8-82.8). Conclusions: Tracheal A-frame deformity is estimated to occur in 36% of children within 3 years after tracheostomy decannulation. Suprastomal collapse, which approaches 74% at 5 years after tracheostomy, is more common when tracheostomy is placed at a younger age. Surgeons caring for tracheostomy-dependent children should recognize acquired airway obstruction and appropriately monitor these outcomes. Level of evidence: 3.

Economic Evaluation of Pediatric Tracheostomy: A Cost of Illness Analysis.

Objective: This study aimed to determine the direct costs of pediatric tracheostomy care within a health care system. Study Design: Prospective analysis. Setting: Academic children's hospital. Methods: Costs associated with caring for pediatric tracheostomy patients under 18 years were analyzed between 2015 and 2021. Direct costs were calculated using the Medicare/Medicaid charges-to-costs ratio for various visit types. Costs were estimated using generalized linear equations, accounting for confounders. Results: A total of 297 children underwent tracheostomy at a median age of 0.94 years. The median follow-up was 2.5 years, resulting in 13,966 visits (mean = 41). The total cost was $321 million. The initial admission accounted for 72% ($231 million) of costs while other inpatient admissions added 24% ($78 million). Emergency department, observation, and outpatient visits comprised 4% of costs. The length of stay (LOS) was the primary cost driver for inpatient visits. Each additional hospital day increased costs by roughly $1195, and each extra admission added about $130,223 after adjusting for confounders. Respiratory failure and infections were the primary reasons for 67% of subsequent admissions. Conclusion: Pediatric tracheostomy care generated over $300 million in direct costs over 5 years. Inpatient stays constituted 96% of these costs, with the LOS being a major factor. To reduce direct health expenditures for these patients, the focus should be on minimizing admissions.

Surgical Outcomes by Early Airway Endoscopy Findings after Pediatric Staged Laryngotracheoplasty.

OBJECTIVES: To determine how initial postoperative airway endoscopy findings after stent removal predict successful decannulation in children undergoing double-staged laryngotracheoplasty (dsLTP). Secondary objectives assessed timing of decannulation and number of endoscopic interventions needed after dsLTP. METHODS: A case series with chart review included children who underwent dsLTP at a tertiary children's hospital between 2008 and 2021. Rates of decannulation, time to decannulation, and number of interventions after dsLTP were recorded for children with high- or low-grade stenosis at the first bronchoscopy after stent removal. RESULTS: Of the 65 children who were included, 88% had high-grade stenosis and 98% had a preoperative tracheostomy. Successful decannulation happened in 74% of the children, and 44% of the children were decannulated within 12 months of surgery. For children with low-grade stenosis at the first endoscopy after stent removal, 84% were successfully decannulated compared with 36% of the children with high-grade stenosis (p = 0.001). After dsLTP, children with high-grade stenosis required 7.5 interventions (SD: 3.3) compared with 4.0 interventions (SD: 3.0) for children with low-grade stenosis (p < 0.001). Decannulated children with high-grade stenosis necessitated more endoscopic procedures (7.0 vs. 3.7, p = 0.02). Time to decannulation was similar between children with high- and low-grade early postoperative stenosis (21.9 vs. 17.8 months, p = 0.63). CONCLUSIONS: Higher grade stenosis identified on the first airway endoscopy after suprastomal stent removal is correlated with lower decannulation rates and more postoperative endoscopic interventions. Although time to decannulation was not impacted by early stenosis grade, surgeons might utilize these early airway findings to counsel families and prognosticate possible surgical success.

Neighborhood Socioeconomic Disadvantage and Long-Term Outcomes After Pediatric Tracheostomy.

OBJECTIVES: To determine whether long-term outcomes after pediatric tracheostomy are impacted by neighborhood socioeconomic disadvantage. METHODS: A prospective cohort of children with tracheostomies was followed at an academic pediatric hospital between 2015 and 2020. Patients were grouped into low or high socioeconomic disadvantage using their neighborhood area deprivation index (ADI). Survival and logistic regression analyses determined the relationship between ADI group, decannulation, and mortality. RESULTS: A total of 260 children were included with a median age at tracheostomy of 6.6 months (interquartile range [IQR], 3.9-42.3). The cohort was 53% male (N = 138), 55% White race (N = 143), and 35% Black or African American (N = 90). Tracheostomy was most frequently indicated for respiratory failure (N = 189, 73%). High neighborhood socioeconomic disadvantage was noted for 66% of children (N = 172) and 61% (N = 158) had severe neurocognitive disability. ADI was not associated with time to decannulation (HR = 0.90, 95% confidence interval [95% CI]: 0.53-1.53) or time to death (HR = 0.92, 95% CI: 0.49-1.72). CONCLUSIONS: Neighborhood socioeconomic disadvantage was not associated with decannulation or mortality among children with a tracheostomy. These findings suggest that long-term outcomes after pediatric tracheostomy are less dependent on socioeconomic factors in an individual community.

Pediatric tracheostomy audiometric outcomes - A quality improvement initiative.

OBJECTIVE: Pediatric tracheostomy patients disproportionately experience hearing loss and are at risk for delayed identification due to their medical complexity. Nonetheless, protocols to monitor hearing in these children are lacking. This quality improvement (QI) initiative aimed to increase the rates of audiometric testing within 12 months of pediatric tracheostomy placement. METHODS: A retrospective cohort study included children who underwent tracheostomy under 18 months of age between 2012 and 2020. Rates of audiometric assessments before and after QI project implementation (2015) were reported along with hearing loss characteristics. RESULTS: A total of 253 children met inclusion. Before project initiation (2012-2014), 32% of children (28/87) obtained audiometric testing within 12 months after tracheostomy. During the first three years of implementation (2015-2017), 39% (38/97) were tested, while 55% (38/69) were tested during the subsequent three years (2018-2020) (P = .01). A passing newborn hearing screen was obtained for 70% of the 210 children with a recorded result, and 198 survived at least 12 months to receive audiometric testing at a median of 11.3 months (IQR: 6.2-22.8) after tracheostomy. Hearing loss was identified for 44% of children (N = 88), of which 42 children initially passed newborn hearing screen. A second assessment was obtained for 62% of children (123/198) at a median of 11.3 months (IQR: 4.5-17.5) after the initial test. In this group, 23% with a previously normal audiometric exam were found to have hearing loss (15/66). CONCLUSIONS: QI initiatives designed to monitor hearing loss in children with a tracheostomy can result in improved rates of audiometric assessments. This population has disproportionately high rates of hearing loss, including delayed onset hearing loss making audiometric protocols valuable to address speech and language development delays.

Assessment of neighborhood-level disadvantage and pediatric obstructive sleep apnea severity.

Objectives: To examine the relationship between neighborhood-level advantage and severe obstructive sleep apnea (OSA) in children. Methods: A retrospective case-control study was conducted on 249 children who underwent adenotonsillectomy and had full-night polysomnography conducted within 6 months prior. Patients were divided into more or less socioeconomically disadvantaged groups using a validated measure, the area deprivation index (ADI). The primary outcomes were the relationship between the apnea-hypopnea index (AHI) and the presence of severe OSA, and the secondary outcome was residual moderate or greater OSA after tonsillectomy. Results: Of the 249 children included in the study, 175 (70.3%) were socially disadvantaged (ADI > 50). The median (interquartile range [IQR]) age was 9.4 (7.3-12.3) years, 129 (51.8%) were male, and the majority were White (151, 60.9%), Black (51, 20.6%), and/or of Hispanic (155, 62.5%) ethnicity. A total of 140 (56.2%) children were obese. The median (IQR) AHI was 8.9 (3.9-20.2). There was no significant difference in the median AHI or the presence of severe OSA between the more and less disadvantaged groups. Severe OSA was found to be associated with obesity (odds ratio [OR] = 3.13, 95% confidence interval [CI] = 1.83-5.34), and residual moderate or greater OSA was associated with older age (OR = 1.20, 95% CI = 1.05-1.38). Conclusions: The ADI was not significantly associated with severe OSA or residual OSA in this cohort of children. Although more neighborhood-level disadvantage may increase the risk of comorbidities associated with OSA, it was not an independent risk factor in this study. Level of Evidence: Level 4.

Long-Term Outcomes of Tracheostomy-Dependent Children.

OBJECTIVE: To estimate the 1-, 5-, and 10-year survival and decannulation rates of children with a tracheostomy. STUDY DESIGN: Ambidirectional cohort. SETTING: Tertiary children's hospital. METHODS: All patients (<18 years) that had a tracheostomy placed between 2009 and 2020 were included and followed until 21 years of age, decannulation, or death. The Kaplan-Meier method estimated cumulative probabilities of death and decannulation. RESULTS: A total of 551 children underwent tracheostomy at a median age of 7.2 months (interquartile range [IQR]: 3.8-49.2). Children were followed for a median of 2.1 years (IQR: 0.7-4.2, range 0-11.5). The cumulative probability of mortality at 1 year was 11.9% (95% confidence interval [CI]: 9.4-15.1), at 5 years was 26.1% (95% CI: 21.6-31.3), and at 10 years was 41.6% (95% CI: 32.7-51.8). Ventilator dependence at index discharge (hazard ratio [HR]: 2.04, 95% CI: 1.10-3.81, p = .03), severe neurologic disability (HR: 2.79, 95% CI: 1.61-4.84, p < .001), and cardiac disease (HR: 1.69, 95% CI: 1.08-2.65, p = .02) were associated with time to death. The cumulative probability of decannulation was 10.4% (95% CI: 8.0-13.5), 44.9% (95% CI: 39.4-50.9), and 54.1% (95% CI: 47.4-61.1) at 1 year, 5 years, and 10 years, respectively. Ventilator dependence (HR: 0.43, 95% CI: 0.31-0.60, p < .001), severe neurologic disability (HR: 0.20, 95% CI: 0.14-0.30, p < .001), and tracheostomy indicated for respiratory failure (HR: 0.68, 95% CI: 0.48-0.96, p = .03) correlated with longer decannulation times. CONCLUSION: After tracheostomy, estimated mortality approaches 42% by 10 years and decannulation approaches 54%. Children with ventilator support at discharge and severe neurological disability had poorer long-term survival and longer times to decannulation.

Survival After Declining Pediatric Tracheostomy Placement.

OBJECTIVE: To determine survival among critically ill children when caregivers decline tracheostomy placement. STUDY DESIGN: Retrospective cohort. METHODS: All children (<18 years) obtaining a pre-tracheostomy consultation at a tertiary children's hospital between 2016 and 2021 were included. Comorbidities and mortality were compared between children of caregivers that declined or agreed to tracheostomy. RESULTS: Tracheostomy was declined for 58 children but was placed for 203 children. After consultation, mortality was 52% (30/58) when declining and 21% (42/230) when agreeing to tracheostomy (p < 0.001) at a mean of 10.7 months (standard deviation [SD]: 16) and 18.1 months (SD: 17.1), respectively (p = 0.07). For those declining, 31% (18/58) died during the hospitalization within a mean of 1.2 months (SD: 1.4) while 21% (12/58) died at a mean of 23.6 months (SD: 17.5) after discharge. Among children of caregivers declining tracheostomy, older age (odds ratio [OR]: 0.85, 95% confidence interval [CI]: 0.74-0.97, p = 0.01) and chronic lung disease (OR: 0.18, 95% CI: 0.04-0.82, P = .03) were associated with lower odds of mortality but sepsis (OR: 9.62, 95% CI: 1.161-57.43, p = 0.01) and intubation (OR: 4.98, 95% CI: 1.24-20.08, p = 0.02) were associated with higher odds of mortality. Median survival after declining tracheostomy was 31.9 months (interquartile range [IQR]: 2.0-50.7) and declining placement was associated with increased mortality risk (hazard ratio [HR]: 4.04, 95% CI: 2.49-6.55, p < 0.001). CONCLUSION: When caregivers declined tracheostomy placement, less than half of critically ill children in this cohort survived with younger age, sepsis, and intubation associated with higher mortality. This information offers valuable insight for families weighing decisions pertaining to pediatric tracheostomy placement. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:3602-3607, 2023.

Estimations of Inpatient and Ambulatory Pediatric Tonsillectomy in the United States: A Cross-sectional Analysis.

OBJECTIVE: To estimate the incidence of inpatient and ambulatory pediatric tonsillectomies in the United States in 2019. STUDY DESIGN: Cross-sectional analysis. SETTING: Healthcare Cost and Utilization Project databases. METHODS: We determined national incidences of hospital-based ambulatory procedures, inpatient admissions, and readmissions among pediatric tonsillectomy patients, ages 0 to 20 years, using the Kids Inpatient Database, Nationwide Ambulatory Surgery Sample, and Nationwide Readmission Database. We described the demographics, commonly associated conditions, complications, and predictors of readmission. RESULTS: An estimated 559,900 ambulatory and 7100 inpatient tonsillectomies were performed in 2019. Among inpatients, the majority were male (59%) and the largest ethnic group was white (37%). Adenotonsillar hypertrophy (ATH), 79%, and obstructive sleep apnea (OSA), 74%, were the most frequent diagnosis and Medicaid (61%) was the most frequent primary payer. The majority of ambulatory tonsillectomy patients were female (52%) and white (65%); ATH, OSA, and Medicaid accounted for 62%, 29%, and 45% of cases, respectively, (all p < .001 when compared to inpatient cases). Common inpatient complications were bleeding (2%), pain/nausea/vomiting (5.6%), and postprocedural respiratory failure (1.7%). On the other hand, ambulatory complications occurred in less than 1% of patients. The readmission rate was 5.2%, with pain/nausea/vomiting and bleeding accounting for 35% and 23% of overall readmissions. All Patient Refined Diagnosis Related Groups severity of illness subclass predicted readmission (odds ratio = 2.18, 95% confidence interval = 1.73-2.73, p < .001). CONCLUSION: A total of 567,000 pediatric ambulatory and inpatient tonsillectomies were performed in 2019; the majority were performed in ambulatory settings. The index admission severity of illness was associated with readmission risk.

Revision Endoscopic Posterior Costal Cartilage Grafting: Is It Feasible?

The objective of this work is to examine the feasibility of revision endoscopic posterior costal cartilage graft (EPCCG) placement for posterior glottic stenosis (PGS) and bilateral vocal fold immobility (BVFI). Revision and primary cases were compared with respect to decannulation rates, and it was hypothesized that there would be no difference in outcomes. Twenty-one patients met inclusion criteria (14 primary, 7 revision). Thirteen (62%) had a primary indication of PGS, and 8 (42%) were for BVFI. There were no differences between revision and primary groups with respect to age, gender, or comorbidities (p > .05). There was no difference between groups with respect to decannulation rate (85% primary vs 100% revision, p = .32). Thus, revision EPCCG appears to have comparable results to primary EPCCG with respect to decannulation rate and time to decannulation. EPCCG may be a feasible alternative to open airway reconstruction for PGS and BVFI in selected patients.

Estimated Probability Distribution of Bleeding After Pediatric Tonsillectomy: A Retrospective National Cohort Study of US Children.

Importance: The American Academy of Otolaryngology-Head and Neck Surgery Foundation has recommended yearly surgeon self-monitoring of posttonsillectomy bleeding rates. However, the predicted distribution of rates to guide this monitoring remain unexplored. Objective: To use a national cohort of children to estimate the probability of bleeding after pediatric tonsillectomy to guide surgeons in self-monitoring of this event. Design, Settings, and Participants: This retrospective cohort study used data from the Pediatric Health Information System for all pediatric (<18 years old) patients who underwent tonsillectomy with or without adenoidectomy in a children's hospital in the US from January 1, 2016, through August 31, 2021, and were discharged home. Predicted probabilities of return visits for bleeding within 30 days were calculated to estimate quantiles for bleeding rates. A secondary analysis included logistic regression of bleeding risk by demographic characteristics and associated conditions. Data analyses were conducted from August 7, 2022 to January 28, 2023. Main Outcomes and Measures: Revisits to the emergency department or hospital (inpatient/observation) for bleeding (primary/secondary diagnosis) within 30 days after index discharge after tonsillectomy. Results: Of the 96 415 children (mean [SD] age, 5.3 [3.9] years; 41 284 [42.8%] female; 46 954 [48.7%] non-Hispanic White individuals) who had undergone tonsillectomy, 2100 (2.18%) returned to the emergency department or hospital with postoperative bleeding. The predicted 5th, 50th, and 95th quantiles for bleeding were 1.17%, 1.97%, and 4.75%, respectively. Variables associated with bleeding after tonsillectomy were Hispanic ethnicity (OR, 1.19; 99% CI, 1.01-1.40), very high residential Opportunity Index (OR, 1.28; 99% CI, 1.05-1.56), gastrointestinal disease (OR, 1.33; 99% CI, 1.01-1.77), obstructive sleep apnea (OR, 0.85; 99% CI, 0.75-0.96), obesity (OR,1.24; 99% CI, 1.04-1.48), and being more than 12 years old (OR, 2.48; 99% CI, 2.12-2.91). The adjusted 99th percentile for bleeding after tonsillectomy was approximately 6.39%. Conclusions and Relevance: This retrospective national cohort study predicted 50th and 95th percentiles for posttonsillectomy bleeding of 1.97% and 4.75%. This probability model may be a useful tool for future quality initiatives and surgeons who are self-monitoring bleeding rates after pediatric tonsillectomy.

Pathogenic bacteria in bronchoalveolar lavage cultures and pediatric laryngotracheal reconstruction outcomes.

OBJECTIVE: The primary objective was to determine if treating pathogenic bacteria in bronchoalveolar lavage (BAL) cultures improves outcomes after pediatric double stage laryngotracheal reconstruction (dsLTR). STUDY DESIGN: Case series with chart review. SETTING: Tertiary children's hospital. METHODS: All children (<18 years) obtaining flexible bronchoscopy with BAL cultures before dsLTR between 2016 and 2022 were included. Cultures identified abnormal bacterial growth or normal respiratory flora. Thirty-day postoperative surgical site or lung infections were captured and tracheostomy decannulation rates were obtained for children with at least 12 months of follow-up. RESULTS: Twenty-seven children obtained presurgical BAL cultures before dsLTR. Median age at reconstruction was 2.9 years (interquartile range: 2.3-3.5) and 89% (24/27) had high grade subglottic stenosis. Positive cultures were obtained in 56% of children (N = 15) with Pseudomonas aeruginosa (40%, 6/15) and methicillin-resistant Staphylococcus aureus (33%, 5/15) the most frequent organisms. All children with positive cultures were treated based on culture and sensitivity data. Postoperative infections developed in 22% (6/27) of children with equal distribution of surgical site and respiratory infections among children with pathogenic bacteria and normal respiratory flora. At 12 months after surgery, the decannulation rate was no different between those treated and not treated for a presurgical positive BAL culture (47% vs. 58%, p = 0.70). CONCLUSION: Pathogenic bacteria are common in BAL cultures from tracheostomy-dependent children before dsLTR. Treatment keeps respiratory infections and decannulation rates similar to children with negative cultures, suggesting continued benefit of flexible bronchoscopy and BAL in preparation for these surgeries.

Sleep Endoscopy and Cine Magnetic Resonance Imaging Evaluation of Children With Persistent Obstructive Sleep Apnea.

OBJECTIVE: To compare findings of same-day cine magnetic resonance imaging (MRI) and drug-induced sleep endoscopy (DISE) and examine how each technique uniquely contributes to the evaluation of persistent obstructive sleep apnea following adenotonsillectomy. STUDY DESIGN: Retrospective cohort study. SETTING: Quaternary care center. METHODS: Chart review was performed for consecutive patients who underwent same-day cine MRI and DISE between 2015 and 2020. Descriptive statistics are reported, and Cohen kappa coefficients were calculated to evaluate the agreement between cine MRI and DISE for obstruction at the adenoids, lingual tonsils, and tongue base. RESULTS: There were 137 patients, the mean age was 10.4 years (95% CI, 3.2-16.7), and 62.8% were male. The most common sites of obstruction on DISE were the tongue base (86.9%), velum (78.7%), epiglottis (74.5%), inferior turbinate (68.6%), and lingual tonsil (61.3%). The most common sites of obstruction on cine MRI were the hypopharynx (56.3%), tongue base (44.8%), lingual tonsil (38.0%), and macroglossia (37.6%). There was moderate agreement for adenoid hypertrophy (κ = 0.53) and poor agreement for lingual tonsil hypertrophy (κ = 0.15) and tongue base obstruction (κ = 0.09). DISE identified more instances of multilevel obstruction when compared with cine MRI (94.9% vs 48.2%). CONCLUSION: DISE offered a better examination of nasal and supraglottic obstruction and is sensitive to partial vs complete collapse, while cine MRI offered better soft tissue resolution for lymphoid tissue hypertrophy and provided a global view of primary and secondary airway obstruction. Cine MRI and DISE are complementary modalities in the evaluation of children with persistent obstructive sleep apnea.

Accidental Tracheostomy Decannulations in Children-A Prospective Cohort Study of Inpatients.

OBJECTIVES: To determine the incidence of tracheostomy accidental decannulations (AD) among pediatric inpatients and identify risks for these events. STUDY DESIGN: Prospective cohort. METHODS: All tracheostomy patients (≤18 years) admitted at a tertiary children's hospital between August 2018 and April 2021 were included. AD were recorded and patient harm was classified as no harm/minor, moderate, or severe. Monthly AD incidence was described as events per 1000 tracheostomy-days. RESULTS: One-hundred seventeen AD occurred among 67 children with 33% (22/67) experiencing multiple events (median: 2.5 events, range: 2-10). Mean age at AD was 4.7 years (SD: 4.4). AD resulted from patient movement (32%, 37/117), performing tracheostomy care (27%, 31/117), repositioning or transporting (15%, 17/117), or unclear reasons (27%, 32/117). A parent or guardian was involved in 28% (33/117) of events. Nearly all AD resulted in no more than minor harm (84%, 98/117) but moderate (12%, 14/117) and severe (4%, 5/117) events did occur. There were no deaths. Tracheostomy care or repositioning were frequently responsible in acute versus subacute events (48% vs. 26%, p = 0.04). Mean monthly AD incidence was 4.7 events per 1000 tracheostomy-days (95% CI: 3.7-5.8) and after implementation of safety initiatives, the mean rate decreased from 5.9 events (95% CI: 4.2-7.7) to 3.7 events (95% CI: 2.5-5.0) per 1000 tracheostomy-days (p = 0.04). CONCLUSIONS: AD in children occur at nearly 5 events per 1000 tracheostomy-days and often result in minimal harm. Quality initiatives targeting patient movement, provider education, and tracheostomy care might reduce the frequency of these complications. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:963-969, 2023.
