Pulmonary and Clinical Outcomes After Bilateral Submandibular Gland Excision and Parotid Duct Ligation for Refractory Sialorrhea.

Importance: Refractory sialorrhea in children can result in pulmonary aspiration and irreversible lung damage. Despite many studies devoted to the surgical treatment of sialorrhea, there is a paucity of objective outcome measures after surgery, especially with regard to pulmonary health. Objectives: To assess whether bilateral submandibular gland excision and bilateral parotid duct ligation ("DROOL" procedure) is associated with reduced pulmonary inflammation in bronchoalveolar lavage (BAL) samples after surgery and to assess patient factors associated with improvement after surgery. Design, Setting, and Participants: This retrospective case series included all 112 patients undergoing the DROOL procedure at a single tertiary care pediatric children's hospital from January 1, 2012, to December 31, 2021. Statistical analysis was performed from March 30 to June 10, 2023, and August 20 to September 23, 2023. Exposure: DROOL procedure for refractory sialorrhea. Main Outcomes and Measures: Degree of pulmonary inflammation (neutrophil percentage) according to BAL cytologic findings and overall bronchoscopy findings up to 12 months before and after the DROOL procedure. Secondary outcomes included number of annual hospitalizations, caregiver report of function before and after the procedure, and need for revision procedures and/or additional operations for secretion management. Results: A total of 112 patients (median age, 3.4 years [IQR, 2.0-7.1 years]; 65 boys [58.0%]) underwent DROOL procedures and had both preoperative and postoperative BAL samples during the study period. Patients demonstrated objective improvement in pulmonary inflammation after surgery, with the median polymorphonuclear neutrophil percentage decreasing from 65.0% (IQR, 14.0%-86.0%) before the surgery to 32.5% (IQR, 3.0%-76.5%) after the surgery (median difference in percentage points, -9.0 [95% CI, -20.0 to 0.0]). Prior to the DROOL procedure, 34 patients (30.4%; 95% CI, 21.8%-38.9%) were hospitalized 2 or more times annually for respiratory illness, which decreased to 10.1% (11 of 109; 95% CI, 4.4%-15.7%) after surgery (3 patients did not have hospitalization data available following surgery). Most caretakers (73 [65.2%]) reported improved secretion management after the procedure. Conclusions and Relevance: This study suggests that patients with impaired secretion management who underwent a DROOL procedure demonstrated improvement in pulmonary inflammation and a reduction in hospitalizations after surgery. Caretakers were also likely to report subjective improvement in secretion management and quality of life. Additional research is necessary to guide optimal timing and patient selection for this procedure.

A multicenter study analyzing the impact of pre-existing comorbidities on laryngotracheal reconstruction (LTR) outcomes.

INTRODUCTION: Comorbidities such as chronic lung disease and gastroesophageal reflux (GERD), prematurity, and numerous other conditions may impact the success of LTR. Single-center studies are limited in terms of patient numbers and may be underpowered. OBJECTIVES: To analyze the impact of specific comorbidities on the operation-specific and overall surgical success of LTR in a large multicenter cohort and validate a predictive model for surgical success. METHODS: A large retrospective multicenter 10-year review was undertaken to validate the data of a previous single-center study (Wertz et al. Laryngoscope 2020) which identified specific predictive comorbidities which impacted LTR outcomes. A Monte Carlo simulation based on the previous data set suggested that 300-400 cases would be needed to optimize the statistical power of a Bayesian model developed from the single-center data to predict surgical success. An IRB-approved data-sharing agreement was executed for 4 large U.S. CENTERS: A virtual REDCap® data entry form inquired about patient characteristics that best predicted surgical success in the single-center model. These included demographics, surgical approaches, cardiac, airway, genetic, endocrine, musculoskeletal, gastrointestinal, and pulmonary comorbidities; details of the surgical procedures, and results of esophagogastroduodenoscopy (EGD), esophageal pH/impedance and flexible bronchoscopy with bronchioalveolar lavage (BAL) were included. Surgical success defined as successful decannulation or resolution of airway symptoms was recorded as single surgery success and overall success following open surgical revision surgery. Multivariate Bayesian analysis, logistical regression, and Kaplan-Meier analysis were performed. RESULTS: 542 patients were identified, including 165 from the single-center study and an additional 377 patients from the multicenter group. The median age was 36 months at the time of the most recent surgery. 70.9% of the LTRs were double-staged procedures. The overall success rate was 86.4% and operation-specific success rate was 69.2%. The specific comorbidities and aerodigestive test results that impacted success based on univariate analysis included staging, bronchiectasis, pulmonary hypertension, GERD, ASD, PDA, grade of stenosis, advanced levels of stenosis, Trisomy 21, MRSA, prior open surgery at another hospital, and gross appearance on EGD. Bayesian model averaging with backward selection was used to validate and refine a predictive model for surgical success with favorable receiver operating curve characteristics - AUC values of 0.827 for single surgery success and 0.797 for overall success. DISCUSSION: With over 500 patients reviewed, this was the largest multicenter study of LTR to date, which elucidated the impact of comorbidities on success with LTR and was able to improve upon the predictive modeling based on single-center data. Patient factors are most critical in the outcome of LTR. Stage and levels of stenosis, as well as pulmonary and GI conditions most strongly impact the likelihood of success. Future prospective case-control studies will be performed to further optimize the current model for outcome prediction and patient management.

Characteristics and Outcomes of Surgical Treatment for Bronchial Anomalies.

OBJECTIVES: Bronchial anomalies are rare but challenging conditions to treat in children, encompassing a variety of structural abnormalities that could compromise airway patency. This includes complete rings, absent cartilage, traumatic avulsions, bronchoesophageal fistulas, and cartilaginous sleeves. The objective of this study is to describe the characteristics and outcomes of a series of pediatric cases of bronchial anomalies that were treated by slide tracheobronchoplasty. METHODS: This is a single-institution retrospective case series of pediatric patients with bronchial anomalies who underwent surgical treatment between February 2004 and April 2020. Data extracted from electronic medical records included patient demographics, comorbidities, and surgical outcomes. RESULTS: There were a total of 29 patients included in the study, of which 14 had complete bronchial rings, 8 had absent bronchial rings, 4 had traumatic bronchial avulsions, 2 had bronchoesophageal fistulas, and one had a cartilaginous sleeve. Median follow-up time was 13 months (with a range of 0.5-213 months). The overall mortality rate was 17.2% (5 patients), all of whom had complete bronchial rings. Patients with complete bronchial rings also had a higher rate of not only cardiac (85.7%) and pulmonary comorbidities (85.7%) but also secondary airway lesions (78.6%). CONCLUSION: This is the largest series to date describing surgical treatment for bronchial anomalies. Complete bronchial rings were the most common anomaly treated, followed by absent rings and trauma. Surgical treatment can be successful but mortality rates are higher in patients with complete bronchial rings, possibly due to higher rates of pulmonary and cardiac comorbidities.

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.

Comparative Treatment Outcomes for Idiopathic Subglottic Stenosis: 5-Year Update.

The North American Airway Collaborative (NoAAC) previously published a 3-year multi-institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating treatment effectiveness. Patients in the NoAAC cohort were re-enrolled for 2 additional years and followed using the prespecified published protocol. Consistent with prior data, prospective observation of 487 iSGS patients for 5 years showed treatment effectiveness differed by modality. Cricotracheal resection maintained the lowest rate of recurrent operation (5%), followed by endoscopic resection with adjuvant medical therapy (30%) and endoscopic dilation (50%). These data support the initial observations and continue to provide value to providers and patients navigating longitudinal decision-making. Level of evidence: 2-prospective cohort study.

Does the History of Tracheoesophageal Fistula Repair Alter Outcomes of Laryngeal Cleft Repair?

OBJECTIVE: Tracheoesophageal fistula and esophageal atresia (TEA) and laryngeal cleft (LC) can coexist in some patients. The surgery-specific success rate of LC repair in children with associated TEA has not been well described. The aim of the study is to determine if the history of TEA alters the LC repair outcomes. STUDY DESIGN: Case series with chart review. SETTING: Single-institution academic medical center. METHOD: A retrospective review was conducted of patients with LC with and without TEA repair between January 2001 and November 2020. Data collected and analyzed included demographics and clinical characteristics, LC type, and LC with TEA timing of repairs. RESULTS: An overall 282 patients met the inclusion criteria of LC repair: LC (n = 242, 85.8%) and LC + TEA (n = 40, 14.2%). Revision repair was required in 43 patients (15.2%) with 8 (2.8%) needing a second revision repair. The first LC revision rate in the LC group was 36/242 (14.9%) as compared with 7/40 (17.5%) in the LC + TEA group (P = .67). The second LC revision rate in the LC and LC + TEA groups was 7 (2.9%) and 1 (2.4%), respectively. The median time to revision was 5.1 months (interquartile range, 3.45-10.6) in the LC group as compared with 29.2 months (interquartile range, 4.8-44.2) in the LC + TEA group (P = .06). CONCLUSION: The incidence of TEA and LC was 14.2% in our study. Based on our findings, history of TEA repair is not associated with a higher revision rate vs LC alone. The history of TEA repair did not alter the outcomes of LC repair.

International Pediatric Otolaryngology Group (IPOG) consensus recommendations: Evaluation and management of congenital tracheal stenosis.

OBJECTIVES: To outline an expert-based consensus of recommendations for the diagnosis and management of pediatric patients with congenital tracheal stenosis. METHODS: Expert opinions were sought from members of the International Pediatric Otolaryngology Group (IPOG) via completion of an 18-item survey utilizing an iterative Delphi method and review of the literature. RESULTS: Forty-three members completed the survey providing recommendations regarding the initial history, clinical evaluation, diagnostic evaluation, temporizing measures, definitive repair, and post-repair care of children with congenital tracheal stenosis. CONCLUSION: These recommendations are intended to be used to support clinical decision-making regarding the evaluation and management of children with congenital tracheal stenosis. Responses highlight the diverse management strategies and the importance of a multidisciplinary approach to care of these patients.

A Deep Learning Approach for Quantifying Vocal Fold Dynamics During Connected Speech Using Laryngeal High-Speed Videoendoscopy.

PURPOSE: Voice disorders are best assessed by examining vocal fold dynamics in connected speech. This can be achieved using flexible laryngeal high-speed videoendoscopy (HSV), which enables us to study vocal fold mechanics with high temporal details. Analysis of vocal fold vibration using HSV requires accurate segmentation of the vocal fold edges. This article presents an automated deep-learning scheme to segment the glottal area in HSV from which the glottal edges are derived during connected speech. METHOD: Using a custom-built HSV system, data were obtained from a vocally healthy participant reciting the "Rainbow Passage." A deep neural network was designed for glottal area segmentation in the HSV data. A recently introduced hybrid approach by the authors was utilized as an automated labeling tool to train the network on a set of HSV frames, where the glottis region was automatically annotated during vocal fold vibrations. The network was then tested against manually segmented frames using different metrics, intersection over union (IoU), and Boundary F1 (BF) score, and its performance was assessed on various phonatory events on the HSV sequence. RESULTS: The designed network was successfully trained using the hybrid approach, without the need for manual labeling, and tested on the manually labeled data. The performance metrics showed a mean IoU of 0.82 and a mean BF score of 0.96. In addition, the evaluation assessment of the network's performance demonstrated an accurate segmentation of the glottal edges/area even during complex nonstationary phonatory events and when vocal folds were not vibrating, thus overcoming the limitations of the previous hybrid approach that could only be applied to the vibrating vocal folds. CONCLUSIONS: The introduced automated scheme guarantees accurate glottis representation in challenging color HSV data with lower image quality and excessive laryngeal maneuvers during all instances of connected speech. This facilitates the future development of HSV-based measures to assess the running vibratory characteristics of the vocal folds in speakers with and without voice disorder.

Consensus on Triple Endoscopy Data Elements Preparatory to Development of an Aerodigestive Registry.

OBJECTIVES/HYPOTHESIS: This study defines essential data elements to be recorded during an aerodigestive "triple endoscopy" to form the foundation of a standardized multicenter registry and to clearly define measurement of each consensus item. STUDY DESIGN: Modified Delphi process. METHODS: Modified Delphi consensus with six survey rounds. Twenty-four expert pediatric otolaryngology, pulmonology, and gastroenterology aerodigestive clinicians from eight large academic pediatric aerodigestive programs formed the Delphi panel. After achieving consensus through the Delphi process, outside validation was performed at 2019 national Aerodigestive Society conference. Consensus, near-consensus, or exclusion was obtained for each proposed data element. Concordance was then measured between expert panel conclusions and validation group conclusions. RESULTS: Overall response rate was 94.4%. 73/167 proposed items reached consensus in six domains (flexible bronchoscopy, bronchoalveolar lavage, microdirect laryngoscopy and bronchoscopy, esophagogastroduodenoscopy with biopsies, and esophageal impedance and pH probe). Measurement of all items was defined; classification/grading systems were selected for 11 items. Validation group endorsed importance of 82/167 data items; compared to expert consensus, overall, inclusion, and exclusion concordance rates were 94.5%, 98.7%, and 90.9%. CONCLUSION: Triple endoscopy is a central component of aerodigestive care. This study identifies and defines data elements to be recorded for all triple endoscopy procedures. The list is of usable length, and clear definitions were created for all items, with explicit classification/grading systems selected for 11 items. Face validity was confirmed with an independent multispecialty sample of aerodigestive providers. This consensus provides the foundation for a triple endoscopy registry but also is immediately applicable to standardize clinical documentation in aerodigestive care.

Surgery and Adjuvant Therapy Improve Derkay Scores in Adult and Pediatric Respiratory Papillomatosis.

OBJECTIVES/HYPOTHESIS: Comparing Derkay anatomical score at time of procedure, disease characteristics, and mean treatment interval among adult and pediatric patients with recurrent respiratory papillomatosis (RRP). STUDY DESIGN: Restrospective study. METHODS: Retrospective review of juvenile-onset (JO) and adult-onset (AO) RRP patients treated longitudinally at pediatric and adult institutions from 1999 to 2019. Patients were included if they had a tissue diagnosis of papilloma and had at least a 12-month follow-up. RESULTS: One hundred and twelve patients met inclusion criteria (68 JO-RRP and 44 AO-RRP). All patients were stratified into either potassium titanyl phosphate (KTP) (n = 42), CO2 (n = 21), or microdebrider (n = 49) treatment groups. The Derkay score improved between first and last procedure in the KTP group (mean difference, 3.5; P < .001), CO2 group (mean difference, 4.4; P < .001), and microdebrider group (mean difference, 4.1; P < .001), but overall improvement did not differ across groups (P = .73). Baseline mean to last mean Derkay score improved for nine patients during bevacizumab treatments (mean difference, 3.0; P = .01) but did not improve for these same patients during an interval prior to receiving bevacizumab treatments. Baseline mean to last mean Derkay score improved for 19 patients during cidofovir treatments (mean difference, 3.84; P < .001) but did not improve for these same patients during the interval prior to receiving cidofovir treatments. The AO-RRP population had more patients with dysplasia (50%) compared to JO-RRP population (10%) (P < .001). CONCLUSION: Various surgical modalities appear to be equally effective treatments for RRP. Adult and pediatric patients have decreased recurrent disease burden when receiving bevacizumab or cidofovir. AO-RRP patients have more concomitant dysplasia.

Quantitative Analysis of Vocal Fold Vibration using High-Speed Videoendoscopy in Children with and without Bilateral Lesions.

OBJECTIVE: To provide data on the measurable vocal fold vibratory differences in children with and without vocal fold lesions using high-speed videoendoscopy. DESIGN: Prospective study, 24 participants (8 healthy; 16 with lesions) between the ages of 5 and 10. METHODS: Rigid high-speed videoendoscopy at the rate of 8,000 frames per second was used to examine participants. Four objective vocal fold phase linearity measures were obtained to establish anterior-posterior contact and separation vibratory patterns. RESULTS: All objective measures showed a difference between nonlesion and bilateral vocal fold lesion groups. Contact-separation patterns in all nonlesion girls and young pre-pubertal boys exhibited an anterior-to-posterior contact and posterior-to-anterior separation; while older boys differed. The objective measures of open quotient, left-right relative phase asymmetry and speed index, showed linear anterior-posterior patterns within the nonlesion group; while the bilateral vocal fold lesion group displayed nonlinear patterns. Patterns in the posterior region of the vocal fold were similar in both groups; while patterns in the anterior region differed. CONCLUSIONS: This study suggests lesions have an effect on the anterior aspect of vocal fold vibratory patterns specifically anterior to the lesions. Age-related differences for males are also evidenced, prompting further investigation of laryngeal development in males and females from childhood to adulthood. This study could serve as a basis for the development of objective clinical measurements of vocal fold vibration in presence of lesions. Further findings could help redefine the theoretical framework of pediatric voice.

Surgical Treatment of Type III Laryngotracheoesophageal Clefts: Techniques and Outcomes.

OBJECTIVES/HYPOTHESIS: Determine surgical and swallowing outcomes after surgery for type III laryngotracheoesophageal cleft (LTEC). STUDY DESIGN: Case series with chart review. METHODS: Chart review was performed on patients with type III LTEC between 2000 and 2019. Demographics, surgical outcomes, and swallowing outcomes were collected and analyzed. RESULTS: Thirty-three patients met inclusion criteria (28 open and 5 endoscopic repairs). Mean age was 3.4 years for the open group and 0.9 years for the endoscopic group. Seventeen (51.5%) patients had a syndromic diagnosis, most commonly Opitz syndrome and Trisomy 21. Mean follow-up was 33.6 months. Thirteen (39.4%) patients had a previous repair attempt prior to repair at our institution. Twenty-four (70.6%) patients had a tracheostomy prior to or at the time of surgical repair and 13 (38.2%) remain tracheostomy-dependent. Nine patients (27.3%) required a revision cleft repair and four (12.1%) required two revisions. Thirty-one patients had an intact repair at last follow-up (93.9). Two patients died outside the hospital over a year after surgery. Preoperatively 13 of 17 patients with swallowing evaluations aspirated. After repair, 11 of 20 patients were deemed safe for all consistencies and seven were safe for thickened. Endoscopic approaches were performed during the last 2 years of the study and had significantly lower operative time (354.4 minutes vs. 171.5 minutes). CONCLUSIONS: Endoscopic and open approaches are effective for treatment of type III LTEC with 27.3% requiring revision and 93.9% of repairs intact at last follow-up. Overall swallowing outcomes were good in patients who underwent postoperative instrumental swallow evaluation. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1112-1117, 2022.

Slide Tracheoplasty for Repair of Complex Tracheoesophageal Fistulas.

OBJECTIVES/HYPOTHESIS: Repair of large, recurrent, and complex tracheoesophageal fistulas (TEFs) is challenging and numerous different surgical approaches exist. These various techniques each carry a set of risks and possible complications such as fistula recurrence, tracheal stenosis or pouches, esophageal stenosis, and recurrent laryngeal nerve injury. Slide tracheoplasty is a reconstructive technique successfully used in many different airway pathologies, including TEF repair. This study examines the success, limits, and complications related to slide tracheoplasty for repair of complex TEFs. STUDY DESIGN: Retrospective chart review. METHODS: Patients undergoing TEF repair using a cervical or thoracic approach slide tracheoplasty, at a single institution, between July 2008 and December 2019 were retrospectively reviewed. Demographic data, comorbidities, TEF etiology and surgical history, slide tracheoplasty details and outcomes, and postoperative complication data were examined using descriptive statistics. RESULTS: Twenty-six patients underwent 27 slide tracheoplasties for TEF (20 cervical approaches, 7 thoracic approaches) with a mean age of 5.2 years (IQR 0.7-7.6) at time of surgery. The most common TEF etiologies included congenital (n = 13), tracheostomy tube erosion (n = 5), and button battery ingestion (n = 4). Fistulas ranged in size from <0.5 mm to 4 cm and 59% had previous endoscopic or open repairs. There were two TEF recurrences (7.4%), one of which was successfully revised and the other which was treated with stent placement. Postoperative complications included dehiscence (3.7%), unilateral vocal fold paralysis (3.7%), and mild tracheal stenosis (18.5%). CONCLUSIONS: Slide tracheoplasty is an effective surgical technique for treating complex congenital and acquired TEFs with lower rates of complications when compared to other techniques. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1542-1547, 2022.

HPV Strain Predicts Severity of Juvenile-Onset Recurrent Respiratory Papillomatosis with Implications for Disease Screening.

Juvenile-onset recurrent respiratory papillomatosis (JoRRP) is the most common benign neoplasm of the larynx in children, presenting with significant variation in clinical course and potential for progression to malignancy. Since JoRRP is driven by human papillomavirus (HPV), we evaluated viral factors in a prospective cohort to identify predictive factors of disease severity. Twenty children with JoRRP undergoing routine debridement of papillomas were recruited and followed for ≥1 year. Demographical features, clinical severity scores, and surgeries over time were tabulated. Biopsies were used to establish a tissue bank and primary cell cultures for HPV6 vs. HPV11 genotyping and evaluation of viral gene expression. We found that patients with HPV11+ disease had an earlier age at disease onset, higher frequency of surgeries, increased number of lifetime surgeries, and were more likely to progress to malignancy. However, the amplitude of viral E6/E7 gene expression did not account for increased disease severity in HPV11+ patients. Determination of HPV strain is not routinely performed in the standard of care for JoRRP patients; we demonstrate the utility and feasibility of HPV genotyping using RNA-ISH for screening of HPV11+ disease as a biomarker for disease severity and progression in JoRRP patients.

Endoscopic Repair of Type 1 Laryngeal Clefts and Deep Interarytenoid Notches: Cold Steel Versus Laser.

OBJECTIVES/HYPOTHESIS: Endoscopic repair is the preferred surgical treatment for type 1 laryngeal clefts (T1LCs) and deep interarytenoid notches (DINs). No studies exist showing differences in repair rates using laser and cold steel. Our objective is to assess overall success and revision rate for endoscopic cleft repair and determine whether there is any difference in surgical outcomes between cold steel and laser techniques. STUDY DESIGN: Retrospective chart review, cohort study. METHODS: Retrospective review at a quaternary care pediatric hospital. Included all patients who underwent endoscopic repair for T1LCs and DINs between January 2010 and December 2019. Demographics, comorbidities, surgical data, outcomes, and revision status were collected and analyzed. We excluded patients who did not have a follow-up at our institution. RESULTS: A total of 194 patients were identified, 14 were excluded for lack of follow-up data so 180 were analyzed. Of these, 127 had cold steel repair and 53 had laser repair. There is no significant difference in demographics or comorbidities. In the cold steel group, 4 of 127 (3.1%) had breakdown and in the laser group, 10 of 53 (18.9%) had breakdown. Patients who failed after a cold steel repair tended to break down later (median 12.7 months) when compared to laser repairs (median 2.1 months). Nine of the 10 patients with breakdown after laser repair were noted on initial postoperative evaluation. CONCLUSIONS: Endoscopic cleft repair is a well-described and effective method for repair of T1LCs and DINs. Both cold steel and laser have high success rates; however, higher failure rates were noted in the laser repair group. Failure after laser repair may occur earlier than failure after cold steel repair. But this did not reach significance. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:2805-2810, 2021.

Vocal Fold Injection Augmentation for Post-Airway Reconstruction Dysphonia: A Case Series.

OBJECTIVES: Post airway reconstruction dysphonia (PARD) is common and has a significant effect on the quality of life of patients. Vocal fold injection augmentation (VFIA) is one treatment that can be used to improve glottic insufficiency in some patients. The goal of this study was to characterize the use and outcomes of VFIA for PARD. METHODS: Retrospective chart review from January 2007 to July 2018 at a tertiary pediatric care center. Consecutive patients with PARD who underwent VFIA, who had a preoperative voice evaluation and a follow-up evaluation within 3 months after VFIA (fat, carboxymethylcellulose gel, hyaluronic acid). RESULTS: Thirty-four patients (20 female) underwent VFIA. The mean age at the time of the injection was 13.6 years (SD 6.1). Twenty patients (58.8%) had a history of prematurity and a mean of 1.8 open airway surgeries. After injection, 29/34 patients (85.3%) noted a subjective voice improvement. The baseline Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) overall severity score decreased by a mean of 5.7 (SD = 19.6) points, P = .12. Total pediatric Voice Handicap Index (pVHI) improved by 6.0 (SD = 19.5) points, from 57.4 (SD = 20.0) to 51.4 (SD = 17.2), P = .09. Functional pVHI subscore demonstrated a significant improvement, with a decrease of 3.4 (SD = 7.3) points, P = .02. All procedures were performed as an overnight observation and no complication occurred. CONCLUSION: Patients with PARD represent a complex subset of patients. VFIA is a straightforward intervention that may improve voice perception. Many patients reported subjective improvement despite minimal objective measurement. Further work is warranted to elucidate the role of injection in management of PARD.

Airway and Swallowing Outcomes Following Laryngotracheoplasty With Posterior Grafting in Children.

OBJECTIVES/HYPOTHESIS: Evaluate swallowing and airway outcomes following laryngotracheoplasty with posterior grafting (LTP PCCG). METHODS: Retrospective review of pediatric patients undergoing LTP PCCG from 2016 to 2019 at a tertiary care pediatric hospital. We included demographics, indications, approach, and revision status. We evaluated preoperative and postoperative instrumental and functional swallow evaluations, and we also gathered information on airway outcomes. RESULTS: Thirty-one patients were included in the study. Median (interquartile range [IQR]) age was 4.0 (2.0, 7.0) years old. Primary indication for surgery was bilateral vocal cord immobility (BVCI) in 11 (35.5%) and posterior glottic stenosis (PGS) in 20 (64.5%). Mean (standard deviation) length of follow-up was 11.0 (8.3) months. Twelve patients had gastrostomy tubes (GT) before surgery, and no patients required placement of GT after surgery. Of the remaining 19 patients, 6 required nasogastric feeding for >4 weeks (average length 1.8 months, longest 3.5 months). At last follow-up, 25 (80.6%) patients were primarily orally fed. Eighteen patients had tracheotomies prior to surgery. No patients without a tracheostomy required placement of tracheostomy before or after surgery and only 1 patient had a tracheostomy at last follow-up. Average time to decannulation was 3.7 months, with surgery-specific success of 87.1% and overall success of 96.8%. Four (12.9%) patients required a major intervention to achieve decannulation. CONCLUSION: LTP PCCG is an effective surgical technique to address PGS and BVCI with high decannulation rates. It may cause temporary swallowing dysfunction, but in this series a majority of children were orally fed at last follow-up. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2798-2804, 2021.

Association of Social Determinants of Health with Time to Diagnosis and Treatment Outcomes in Idiopathic Subglottic Stenosis.

OBJECTIVES: To examine whether social determinants of health (SDH) factors are associated with time to diagnosis, treatment selection, and time to recurrent surgical intervention in idiopathic subglottic stenosis (iSGS) patients. METHODS: Adult patients with diagnosed iSGS were recruited prospectively (2015-2017) via clinical providers as part of the North American Airway Collaborative (NoAAC) and via an online iSGS support community on Facebook. Patient-specific SDH factors included highest educational attainment (self-reported), median household income (matched from home zip code via U.S. Census data), and number of close friends (self-reported) as a measure of social support. Main outcomes of interest were time to disease diagnosis (years from symptom onset), treatment selection (endoscopic dilation [ED] vs cricotracheal resection [CTR] vs endoscopic resection with adjuvant medical therapy [ERMT]), and time to recurrent surgical intervention (number of days from initial surgical procedure) as a surrogate for disease recurrence. RESULTS: The total 810 participants were 98.5% female, 97.2% Caucasian, and had a median age of 50 years (IQR, 43-58). The cohort had a median household income of $62 307 (IQR, $50 345-$79 773), a median of 7 close friends (IQR, 4-10), and 64.7% of patients completed college or graduate school. Education, income, and number of friends were not associated with time to diagnosis via multivariable linear regression modeling. Univariable multinominal logistic regression demonstrated an association between education and income for selecting ED versus ERMT, but no associations were noted for CTR. No associations were noted for time to recurrent surgical procedure via Kaplan Meier modeling and Cox proportional hazards regression. CONCLUSIONS: Patient education, income, and social support were not associated with time to diagnosis or time to disease recurrence. This suggests additional patient, procedure, or disease-specific factors contribute to the observed variations in iSGS surgical outcomes.

The Impact of Socioeconomic Status on Time to Decannulation Among Children With Tracheostomies.

OBJECTIVE: To determine if time to tracheostomy decannulation differs among children by socioeconomic status. STUDY DESIGN: Case series with chart review. SETTING: Tertiary pediatric medical center. METHODS: Patients (≤21 years old) who underwent tracheostomy from January 1, 2011, to December 31, 2016. Patients were divided into 2 groups based on their socioeconomic status (SES), low SES and high SES. Principal components analysis was used to create an index for SES using census data obtained by the US Census Bureau's American Community Survey 5 year data profile from 2013 to 2017. Statistical analysis was performed using a χ2 for categorical variables and Wilcoxon rank-sum test for continuous variables. A general linear model was constructed to control for clinical factors to understand the independent effect of SES on time to decannulation. RESULTS: In total, 215 patients were included; of these patients, 111 patients (52%) were included in the high-SES group and 104 patients (48%) were included in the low-SES group. There was a significant difference in the time to decannulation for children based on SES status, with those children in the low-SES group taking on average 10 months longer to decannulate (38.7 vs 28.0 months, P = .0007). Median follow-up was 44.1 months (interquartile range, 29.6-61.3 months). CONCLUSION: Health care disparities appear to exist among children undergoing decannulation of their tracheostomy tube. Patients with lower SES had a significantly longer time to decannulation than those with higher SES.

Management of A-Frame Tracheal Deformity in Children With Endoscopic Resection Tracheoplasty.

OBJECTIVES: Tracheal A-frame deformity is a known consequence of tracheostomy that may lead to obstruction after decannulation. The goal of this study is to demonstrate the feasibility and success of endoscopic carbon dioxide (CO2 ) laser-assisted tracheoplasty of tracheal A-frame deformity in children. METHODS: Retrospective case series of symptomatic children with tracheal A-frame deformity with no other site of airway obstruction (2016-2018). All patients underwent CO2 -laser assisted endoscopic resection tracheoplasty. RESULTS: Eight patients (six male) were included with a median age of 15.4 (IQR 12.3-17.9) years. Patients had a median of two previous open airway surgeries (IQR 1-2.5) and all patients had a history of tracheostomy with successful decannulation. Tracheal A-frame deformity presented as dyspnea on exertion for all patients (n = 8, 100%). Obstructive sleep apnea was confirmed for all patients who underwent polysomnography (4/4, 100%). Median interval from decannulation to development of symptoms was 8.7 years (IQR 5.8-9.3). All patients sized with an age-appropriate endotracheal tube despite the deformity. Endoscopic A-frame tracheoplasty was successful for 7/8 (87.5%) patients and was performed with overnight observation for these patients (8/8, 100%). Unilateral A-frame tracheoplasty was performed successfully for five patients (62.5%), bilateral A-frame tracheoplasty was performed successfully for two patients (25.0%), and one patient (12.5%) did not have complete resolution of symptoms after bilateral A-frame tracheoplasty due to multi-level airway obstruction. CONCLUSIONS: CO2 laser-assisted tracheoplasty is an innovative endoscopic technique to relieve symptoms of airway obstruction for selected patients with tracheal A-frame deformity although avoiding the morbidity and hospital stay duration associated with tracheal resection.
