Characteristics and management of pediatric medial subperiosteal orbital abscesses.

INTRODUCTION: Subperiosteal orbital abscesses (SPOA) are the most common suppurative complications of acute bacterial sinusitis. Medial SPOAs arise from infection of the ipsilateral ethmoid sinus and favor initial conservative management reserving surgical drainage for patients who do not demonstrate clinical improvement. No standard algorithm defining medical versus surgical treatment of medial SPOAs exist in the pediatric population. OBJECTIVES: To identify a size cutoff for medial SPOAs to predict the likelihood for surgical drainage. METHODS: This is a retrospective review of patients with medial SPOAs at a tertiary care center from 2003 to 2017. Diagnosis of SPOA was based on radiographic findings. Variables included are patient demographics, antibiotic therapy, surgical intervention, and length of stay. RESULTS: 82 patients with a medial SPOA were included with an average age at presentation of 6.27 (range 0-15) years were included in this study. 62 patients were male (75.6 %), and 20 were female (24.4 %). The average abscess length was 16.1 mm, range 4.5-30.7 mm. The average abscess width was 4.17 mm, range 1.5-14.6 mm. The odds ratio for surgical treatment with every 1 mm increase in abscess width was 1.89 (95CI:1.33-2.69, p < 0.001). Abscesses over 3.6 mm width were 6.65 times more likely to undergo surgical drainage than those less than 3.6 mm (OR:6.65, 95CI:2.52-17.54, p < 0.001). The average(SD) length of stay was 5.4(3.0) days for patients who underwent surgery and 4.0(0.9) days for patients treated with conservative measures, p < 0.001. CONCLUSION: Medial SPOAs greater than 3.6 mm were more likely to undergo surgical drainage; however there was no difference in the likelihood of drainage between anteriorly and posteriorly based medial abscesses. These findings help further characterize the landscape of pediatric subperiosteal abscesses that are managed with surgical drainage.

Degrees of Inflammation in the Treatment of Subglottic Stenosis in a Rabbit Model: Histopathological Assessment of a Novel Bioabsorbable Ultra-high Ductility Magnesium Alloy Stent.

OBJECTIVE: Utilizing a novel histopathological scoring system and subglottic stenosis (SGS) rabbit model, we aimed to compare degrees of inflammation and severity of narrowing in the subglottis between two minimally invasive therapeutic modalities: endoscopic balloon dilation (EBD) alone versus EBD with placement of a bioabsorbable ultra-high ductility magnesium (UHD-Mg) alloy stent. METHODS: SGS was induced endoscopically via microsuspension laryngoscopy in 23 New Zealand white rabbits. The control group (n = 11) underwent EBD alone, the study arm (n = 12) underwent EBD with implantation of bioabsorbable UHD-Mg alloy stents. Rabbits were euthanized at 2-, 3-, and 6-weeks after SGS induction, coinciding with wound healing stages. Using Optical Coherence Tomography (OCT), cross-sectional areas of airways were compared to calculate the mean percentage of intraluminal area at sequential time points. A novel histopathological scoring system was used to analyze frozen sections of laryngotracheal complexes. The degree of inflammation was quantified by scoring changes in inflammatory cell infiltration, epithelial ulceration/metaplasia, subepithelial edema/fibrosis, and capillary number/dilation. Univariate analysis was utilized to analyze these markers. RESULTS: We found rabbits implanted with the bioabsorbable UHD-Mg alloy stent had statistically significantly higher scores in categories of hyperplastic change (stents vs controls: 1.48 vs 0.46 p < 0.001), squamous metaplasia (22 vs 5 p < 0.001), and neutrophils/fibrin in lumen (31 vs 8, p < 0.001). Rabbits who received EBD alone had higher scores of subepithelial edema and fibrosis (2.70 vs 3.49, p < 0.0256). The stented rabbits demonstrated significantly increased mean percent stenosis by intraluminal mean area compared to controls at 2 weeks (88.56 vs 58.98, p = 0.032), however at all other time points there was no significant difference between intraluminal subglottic stenosis by mean percent stenosis area. DISCUSSION: Rabbits with SGS treated with UHD-Mg alloy stents demonstrated histopathologic findings suggestive of lower levels of tracheal fibrosis. This could indicate a reduced tendency towards the development of stenosis when compared to EBD alone. There was not a difference in luminal size between stent and non-stented rabbits at the six-week end point. Histologically, however, overall the use of bioabsorbable UHD-Mg alloy stenting elicited a greater tissue response at the level of the superficial mucosa rather than fibrosis of the lamina propria seen in the stented rabbits. This suggests more favorable healing and less of a tendency towards fibrosis and stenosis even though there may not be a benefit from a luminal size standpoint during this early healing period. Compared to known complications of currently available non-bioabsorbable metal or silicone-based stents, this proof-of-concept investigation highlights the potential use of a novel biodegradable UHD-Mg stent as a therapeutic modality for pediatric SGS.

Effect of Speaking Valves on Tracheostomy Decannulation.

Introduction Despite several pediatric tracheostomy decannulation protocols there remains tremendous variability in practice. The effect of tracheostomy capping on decannulation has been studied but the role of speaking valves (SVs) is unknown. Objective Given the positive benefits SVs have on rehabilitation, we hypothesized that SVs would decrease time to tracheostomy decannulation. The purpose of the present study was to evaluate this in a subset of patients with chronic lung disease of prematurity (CLD). Methods A retrospective chart review was performed at a tertiary care children's hospital. A total of 105 patients with tracheostomies and CLD were identified. Data collected included demographics, gestational age, congenital cardiac disease, airway surgeries, granulation tissue excisions, SV and capping trials, tracheitis episodes, and clinic visits. Statistics were performed with logistic and linear regression. Results A total of 75 patients were included. The mean gestational age was 27 weeks (standard deviation [SD] = 3.6) and the average birthweight was 1.1 kg (SD = 0.6). The average age at tracheostomy was 122 days (SD = 63). A total of 70.7% of the patients underwent decannulation and the mean time to decannulation (TTD) was 37 months (SD = 19). A total of 77.3% of the patients had SVs. Those with an SV had a longer TTD compared to those without (52 versus 35 months; p = 0.008). Decannulation was increased by 2 months for every increase in the number of hospital presentations for tracheitis ( p = 0.011). Conclusion The present study is the first, to our knowledge, to assess the effect of SVs on tracheostomy decannulation in patients with CLD showing a longer TTD when SVs are used.

Use of botox for sialorrhea and dysphagia in the neonatal population.

INTRODUCTION: Botox is frequently used for sialorrhea in patients with compromised airways and those with etiologies causing difficulty with secretion management (i.e. strokes, neurologic disorders, etc.). There are no published studies regarding the use of botulinum toxin (BoNT) in the neonate population. We aim to discuss our experience and safety of BoNT use in the neonate population in regards to alleviating secretion management and airway protection. METHODS: Retrospective review of neonates admitted to the neonatal intensive care unit (NICU) ≤12 months of age who received BoNT injection to submandibular (SMG) and parotid (PG) glands for sialorrhea/dysphagia. BoNT was administered under ultrasound (u/s) guidance by interventional radiology. RESULTS: 6 children were examined. 2 (33 %) were male. Avg NICU stay was 87.5 ± 33.1 days. 2 underwent surgical airway intervention prior to injection. Mean age at initial BoNT was 1.5 ± 0.7 months. Avg weight at injection was 4 ± 1.1 kg. Each PG and SMG were injected in 5/6 cases. Bilateral SMG were unidentified on u/s in 1 case and thus not injected. Dose range injected per gland was 5-15u. 100 % required tube feeds, 50 % with tubes distal to stomach (NJT/NDT). 83 % were completely NPO prior to injection and there was no noted clinical improvement in oral skills post injection. All had noted desats/apneas prior to injection and 83 % had reported decreased events post injection. 50 % had reported decrease O2 requirements and frequent suctioning 2wks after injection, however 2 (33 %) required surgical airway intervention after injection (trach, SGP/MDO). 4/6 (67 %) trialed medical therapy, anticholinergics being the most common. 50 % underwent 2nd injection (age = 6.5 ± 0.3 months) avg. 4.7 ± 0.7mo after 1st injection, and the same 3pts underwent 3rd injection (age = 12.5 ± 2.4 months) avg. 6.1 ± 2.5mo after 2nd injection. 1 pt. had a total 6 injections. There were no injection related complications. CONCLUSION: BoNT injection is a safe, non-invasive alterative for management of sialorrhea in neonates. Further extensive study needs to be performed to identify the optimal dose per gland in this population.

Pediatric Tracheostomy Safety: Implementation of an Airway Safety Placard.

BACKGROUND: First health care professionals arriving at the bedside in tracheostomy-related emergencies are rarely the surgical subspecialists who placed the tracheostomy and are unfamiliar with the relevant anatomy and tracheostomy specifications for the individual patient. We hypothesized that implementing a bedside airway safety placard would increase caregiver confidence, understanding of airway anatomy, and management of patients with a tracheostomy. METHODS: A prospective survey study was performed by distributing a tracheostomy airway safety survey before and after implementation of an airway safety placard in a 6-month study period. Placards emphasizing critical airway anomalies as well as emergency management algorithm suggestions designed by the otolaryngology team at the time of tracheostomy were placed at the head of the bed and traveled with the patient during transport around the hospital. RESULTS: Of 377 staff members requested to complete the surveys, 165 (43.8%) responses were obtained, and 31 (8.2% [95% CI 5.7-11.5]) paired pre- and post-implementation responses were recorded. Differences were found in the paired responses, including increases in the domains of confidence (P = .009) and experience (P = .01) post implementation. Less experienced providers (≤ 5 y of experience) (P = .005) and providers from neonatology (P = .049) demonstrated improved confidence post implementation, which was not observed in their more experienced (> 5 y) or respiratory therapy counterparts. CONCLUSIONS: Given the limitations of a low survey response rate, our findings suggest that an educational airway safety placard initiative can be a simple, feasible, and low-cost quality improvement tool to enhance airway safety and possibly decrease potentially life-threating complications among pediatric patients with a tracheostomy. The implementation of the tracheostomy airway safety survey at our single institution warrants a larger multi-center study and validation of the survey.

Pediatric peanut aspirations before and after 2015 recommendation for early peanut exposure.

OBJECTIVES: To investigate if there has been an increase in peanut foreign body aspirations (FBA) in children since the publication of the Learning Early About Peanut Allergy (LEAP) trial, which revealed that early exposure to peanut-containing foods prevented peanut allergies in children at risk of atopic disease. METHODS: Retrospective chart reviews were conducted separately at two pediatric institutions. Institutions One and Two reviewed children less than 7 years old who underwent bronchoscopy for FBA over ten-year periods between January 2007 and September 2017 and November 2008 and May 2018, respectively. The proportion of FBAs attributed to peanuts was compared before and after the publication LEAP. RESULTS: Out of 515 reviewed cases, there was no change in pediatric peanut aspirations prior to and following the LEAP trial and AAP guideline change (33.5% vs 31.4%, p = 0.70). At Institution One, 317 patients met inclusion criteria. When comparing FBAs before and after LEAP, there were no significant changes in the rate of peanut aspiration (53.5% vs. 45.1%, p = 0.17). Institution Two also found no significant increase in the rate of peanut aspirations before and after the Addendum Guidelines (41.4% vs. 28.6%, p = 0.65) upon review of 198 cases. CONCLUSIONS: Multiple institutions demonstrated a non-significant change in the rate of peanut FBAs following the AAP recommendation. Given that peanuts comprise a large proportion of FBAs, it is important to continue to track peanut aspirations. Longer term data tracking is needed from more institutions to further understand how recommendations from other specialties and the media impacts pediatric aspiration outcomes.

Prevalence and Management of Laryngomalacia in Patients With Pierre Robin Sequence.

OBJECTIVE: To characterize the prevalence and presentation of laryngomalacia and efficacy of supraglottoplasty (SGP) in a cohort of patients with Pierre Robin Sequence (PRS). DESIGN: Retrospective cohort study. SETTING: Tertiary-care children's hospital. PATIENTS, PARTICIPANTS: Consecutive patients with PRS born between January 2010 and June 2018. MAIN OUTCOME MEASURES: Chart review included demographics, comorbid airway obstruction including laryngomalacia, timing of surgical interventions, clinical symptoms, sleep study data, and modified barium swallow study data.126 patients with PRS were included; 54% had an associated syndrome, 64% had an overt cleft palate, and 22% had a submucous cleft palate. 64/126 were noted to have laryngomalacia (51%). Patients with concurrent PRS and laryngomalacia were significantly more likely to have submucous cleft palate (P = .005) and present with aspiration with cough (P = .01) compared to patients with PRS without laryngomalacia. Patients with concurrent laryngomalacia and PRS showed a significant decrease in apnea-hypopnea index (AHI) and obstructive AHI (OAHI) after mandibular distraction, with a median AHI and OAHI improvement of 22.3 (P = .001) and 19.8 (P = .002), respectively. Patients who underwent only SGP did not show significant improvement in these parameters (P = .112 for AHI, P = .064 for OAHI).The prevalence of laryngomalacia in our PRS cohort was 51%. Patients with PRS and laryngomalacia are more likely to present with overt aspiration compared to patients with PRS without laryngomalacia. These data support that laryngomalacia does not appear to be a contraindication to pursuing MDO.

Evaluation of Upper Airway Stimulation for Adolescents With Down Syndrome and Obstructive Sleep Apnea.

Importance: Patients with Down syndrome have a high incidence of persistent obstructive sleep apnea (OSA) and limited treatment options. Upper airway hypoglossal stimulation has been shown to be effective for adults with OSA but has not yet been evaluated for pediatric populations. Objective: To evaluate the safety and effectiveness of upper airway stimulation for adolescent patients with Down syndrome and severe OSA. Design, Setting, and Participants: This prospective single-group multicenter cohort study with 1-year follow-up was conducted between April 1, 2015, and July 31, 2021, among a referred sample of 42 consecutive adolescent patients with Down syndrome and persistent severe OSA after adenotonsillectomy. Intervention: Upper airway stimulation. Main Outcomes and Measures: The prespecified primary outcomes were safety and the change in apnea-hypopnea index (AHI) from baseline to 12 months postoperatively. Polysomnographic and quality of life outcomes were assessed at 1, 2, 6, and 12 months postoperatively. Results: Among the 42 patients (28 male patients [66.7%]; mean [SD] age, 15.1 [3.0] years), there was a mean (SD) decrease in AHI of 12.9 (13.2) events/h (95% CI, -17.0 to -8.7 events/h). With the use of a therapy response definition of a 50% decrease in AHI, the 12-month response rate was 65.9% (27 of 41), and 73.2% of patients (30 of 41) had a 12-month AHI of less than 10 events/h. The most common complication was temporary tongue or oral discomfort, which occurred in 5 patients (11.9%). The reoperation rate was 4.8% (n = 2). The mean (SD) improvement in the OSA-18 total score was 34.8 (20.3) (95% CI, -42.1 to -27.5), and the mean (SD) improvement in the Epworth Sleepiness Scale score was 5.1 (6.9) (95% CI, -7.4 to -2.8). The mean (SD) duration of nightly therapy was 9.0 (1.8) hours, with 40 patients (95.2%) using the device at least 4 hours a night. Conclusions and Relevance: Upper airway stimulation was able to be safely performed for 42 adolescents who had Down syndrome and persistent severe OSA after adenotonsillectomy with positive airway pressure intolerance. There was an acceptable adverse event profile with high rates of therapy response and quality of life improvement. Trial Registration: ClinicalTrials.gov Identifier: NCT02344108.

Initiation of acid suppression therapy for laryngomalacia.

OBJECTIVE: Evidence supporting the use of acid suppression therapy (AST) for laryngomalacia (LM) is limited. The objective of this study was to determine if outpatient-initiated AST for LM was associated with symptom improvement, weight gain, and/or avoidance of surgery. METHODS: A retrospective cohort was reviewed at a tertiary-care children's hospital. Patients were included if they were diagnosed with LM at ≤6 months of age, seen in an outpatient otolaryngology clinic between 2012 and 2018, and started on AST. Primary outcomes were improvement of airway and dysphagia symptoms, weight gain, and need for surgery. Severity was assessed by symptom severity. RESULTS: Of 2693 patients reviewed, 199 met inclusion criteria. Median age of diagnosis was 4 weeks (range: 0-29 weeks). LM was classified as mild/moderate (71.4%) and severe (28.6%) based on symptom severity. Severity on flexible fiberoptic laryngoscopy (FFL) was not associated with clinical severity. Weight percentile, airway symptoms, and dysphagia symptoms improved within the cohort. In total, 26.1% underwent supraglottoplasty (SGP). In multivariate analysis, only severe LM on FFL was predictive of SGP (OR: 7.28, 95%CI: 1.91-27.67, p = .004). CONCLUSION: Clinical symptom severity did not predict response to AST raising the question of utility of AST in LM. Severity of LM based on FFL, not clinical severity, was associated with decision to pursue SGP. Prospective randomized trials are needed to better understand the role of AST in LM. LEVEL OF EVIDENCE: Level 3.

Pediatric Tracheostomy Care Simulation: Real-Life Scenarios in a Safe Learning Environment.

BACKGROUND: Pediatric patients require tracheostomy tube placement as a last resort for critical airway management. Around-the-clock care is needed at discharge because of the high risk of morbidity and mortality associated with a tracheostomy. The potential for catastrophic sequalae can create a high stress home environment. A simulation program that used a high-fidelity manikin was implemented to reduce complications, morbidity and mortality, and improve skills for real-life medical scenarios. METHODS: A tracheostomy care simulation program was implemented at a large tertiary care children's hospital from October 2019 to October 2020. Caregivers participated in a pre-post program survey and rated 9 statements on a 5-point scale with regard to knowledge, confidence, and comfort level of taking care of their child at home. Emergency scenarios included accidental tracheostomy tube dislodgement, tracheostomy tube plugging, cardiac arrest, and ventilator failure. Classes were recorded for objective start-to-finish scenario time stamps and prompt rates. A medical chart review was performed 90 d after discharge. RESULTS: Eighteen caregivers for 10 children participated. For the 10 children, there was a 9.1% increase in the average total score agreement from pre to post survey, with scores going from "agree" to "strongly agree" (P = .001). Each subset of questions had a significant increase in scores after participation: knowledge, P = .002; confidence, P = .006; and comfort, P = .01. The caregivers required an average 20% prompt rate for the next step in the scenario. Children were 70% female, 80% white, and 60% had public insurance and had their tracheostomy tube placed at a median age of 4 months (range, 0 months to 24 years). Three children (n = 3/9 [33.3%]) were readmitted for tracheitis within 90 d after being discharged to home. CONCLUSIONS: Caregiver knowledge, confidence, and comfort levels were increased after participation. Pediatric patients with a tracheostomy are medically fragile, therefore, it is important for caregivers to be aware of and prepared for common tracheostomy emergencies and to "experience" emergency situations firsthand.

Dysphagia in Pediatric Patients with Tracheostomy.

OBJECTIVE: Post-tracheotomy swallowing function has not been well described in the pediatric population. This study aims to (1) determine differences in swallowing functioning pre- and post-tracheotomy and (2) examine the association between postoperative dysphagia and indication for tracheotomy, age at the time of tracheotomy, and time between tracheotomy and modified barium swallow (MBS). METHODS: A retrospective chart review was performed on 752 patients who underwent a tracheotomy from 2003 to 2018 and had adequate documentation for review. Patients were included if they received a post-operative MBS. Descriptive statistics, logistic regression, and Fisher's exact test were used to analyze the data. RESULTS: The cohort included 233 patients. The mean age at the time of tracheotomy was 25 months (±50.5). The indications for the tracheotomy were upper airway obstruction (110/233, 47.2%), chronic respiratory failure (104/233, 44.6%), and neurologic disease (19/233, 8.2%). The mean time from tracheotomy to post-operative MBS was 224 days (±297.7). Of the patients who had documented pre- and post-tracheotomy diets, nearly half of patients had improvement in their swallowing function after tracheotomy placement (82/195; 42.1%). Post-tracheotomy MBS recommended thickened liquids in 30.9% of the patients (72/233) and 42.5% (99/233) were recommended thin liquids. The remainder (62/233, 26.6%) remained nothing by mouth (NPO). Patients with neurological disease as the indication for the tracheotomy were more likely to remain NPO (P = .039). CONCLUSION: A tracheotomy can functionally and anatomically affect swallowing in pediatric patients. The majority of our studied cohort was able to resume some form of an oral diet postoperatively based on MBS. This study highlights the need for objective measurements of swallowing in the postoperative tracheotomy patient to allow for safe and timely commencement of an oral diet. LEVEL OF EVIDENCE: Level 3.

Primary versus secondary closure of tracheocutaneous fistula in pediatric patients.

OBJECTIVE: Up to 50% of pediatric patients have a persistent tracheocutaneous fistula (TCF) after tracheostomy decannulation. Classically these fistula tracts were excised and completely closed in a multilayered fashion, but recently closure by secondary intention has become the standard of care. However, variations in postoperative care still exist. The primary objectives of this study were to compare outcomes between patients who had a primary closure versus closure by secondary intention after excision of a TCF in children with a tracheostomy placement at one year old or less and to determine if closure by secondary intention will be equally efficacious compared to traditional primary closure. METHODS: Patients ages 0-21 years who had a primary or secondary closure of a TCF at a tertiary care children's hospital following decannulation of a tracheostomy tube were reviewed and those with a tracheostomy placement ≤1 year old were included. Demographic information, comorbidities, and surgical information were extracted from inpatient and outpatient charts. Mann-Whitney U test, Fisher's Exact test, and logistic regression to compare outcomes across the two TCF surgical groups. RESULTS: A total of 64 patients met inclusion with primary closures in 25 (39.1%) patients and secondary closures in 39(60.9%) patients. Patients who underwent secondary closure had a significantly shorter surgery duration (p < .001), shorter ICU length of stay (p < .001), and shorter postop LOS (p < .001). There were no differences in cardiac complications, respiratory complications, and the need for additional closure surgery between the two techniques, p > .05. Time from decannulation to TCF in months increased with primary closure, p = .010. CONCLUSION: Closure of tracheocutaneous fistula by secondary intention is safe and effective and can allow for shorter hospital stays in children with a tracheostomy placement at a year old or less.

Readmissions and mortality in pediatric tracheostomy patients: Are we doing enough?

OBJECTIVES: Pediatric patients who undergo tracheostomy tube placement are medically complex with a high risk of morbidity and mortality. They are often premature with multiple cardiopulmonary comorbidities. This study reviews the demographics and outcomes within this population to identify at-risk patient groups at our hospital. METHODS: A retrospective chart review of those with pediatric tracheostomy placement from 2015 to 2016 at our hospital was performed (n = 92). Demographic and post-discharge data were collected at 30, 60, and 90-days during the global period. RESULTS: Ventilator dependence was the most common reason for placement. 79.3% of patients had two or more major comorbidities. 44% had an emergency department (ED) visit and subsequent hospital admission within the first 90 days post-discharge, with 36% being trach/respiratory-related. The 90-day mortality was 19.6%; however, at the time of chart review, mortality was 35% with only 1 (1.1%) being from trach-related complications. Patients with longer admissions were more likely to die prior to discharge, p = .001. Lastly, patients who died were 3 times more likely to have > 25% no-shows to their outpatient appointments compared to those living throughout the study period. CONCLUSION: Our population had a high incidence of ED visits, readmission rates, and mortality; however, trach-related causes remained low. Mortality risk increased with more no-show appointments and residing a further distance from our hospital. Furthermore, multiple co-morbidities, with longer hospital stays also increased risk of mortality. Identifying those with the highest risk for complications will enable us to target families for increased home-care education to decrease readmissions and mortality. LEVEL OF EVIDENCE: 4.

Exploring caregiver burden and financial toxicity in caregivers of tracheostomy-dependent children.

OBJECTIVE: Measure the prevalence of and factors associated with financial toxicity (FT) and caregiver burden in families of tracheostomy-dependent children. FT is defined as the objective and subjective patient-level impact of the costs of medical care and has been associated with lower quality of life, decreased compliance with treatment, and increased mortality. METHODS: A medical record review was performed on all children with a tracheostomy tube placed from 2009 to 2018 at a tertiary children's hospital to identify and include children younger than 18 years old, not deceased, and not decannulated at the time of review. Eligible children's caregivers were contacted to fill out a 36-item questionnaire and three validated instruments: The Comprehensive Score for Financial Toxicity (COST) and the Financial Distress Questionnaire (FDQ), both addressed to the parent/primary caregiver, and the Burden Scale for Family Caregivers - short version (BSFC-s). RESULTS: Of the 140 eligible tracheostomy patients identified, 45 caregivers (32.1%) returned the survey. The average COST score was 18 ± 1.7 with 73.3% of caregivers reporting high toxicity based on FDQ, and 75.6% having severe-to-very severe caregiver burden. Significant increase in FT was seen in households where an adult had to leave a paid position (p = 0.047) or work less (p = 0.002) because of their child's condition; or needed to omit some of the child's medical services or medications due to cost-prohibitive reasons (p<0.001). Financial toxicity was associated with caregiver burden (by BSFC-s) [r = -596; beta coefficient = -0.95, t(43) = -4.87, p<0.001] and financial distress (by FDQ; p<0.001). CONCLUSION: Caregivers of children with medically complex, tracheostomy-dependent conditions suffer from FT and caregiver burden. As a result, harmful financial coping mechanisms such as missing necessary care components or forgoing prescribed treatments, may be adopted for cost-prohibitive reasons.

Pediatric subperiosteal orbital abscess characterization and prediction of size, location, and management.

INTRODUCTION: Subperiosteal orbital abscess (SPOA) is a serious suppurative complication of pediatric sinusitis. The objective of this study is to stratify patient selection into those best treated medically versus surgically based on clinical outcomes. METHODS: This is a retrospective review of patients diagnosed with SPOA complicating sinusitis treated at a tertiary care pediatric hospital from 2002 through 2016. SPOA was diagnosed by CT scan. Characteristics evaluated include demographics, abscess size, location, and measurements, length of hospital stay, medical and surgical interventions, presenting symptoms, and complications. RESULTS: A total of 108 total SPOA secondary to sinusitis patients were included. A majority, 72.2%, were male with an average age at presentation of 6.8 years. The mean ± standard deviation abscess cubic volume was 0.98 ± 1.27 cm3 (median(range) = 0.44(0.01-7.34 cmcm3)). With an abscess volume of 0.510 cm3, there was a sensitivity of 71.2% and a specificity of 84.4% for needing surgical drainage. Those with large abscesses at our volume threshold were 13 times more likely to require surgery than those with small abscesses, OR: 13.41, 95%CI: 5.02-35.86, p < .001. Patients that required surgery had an abscess closer to the orbital apex with the majority, 25 (61.0%), being the most proximal to the apex, p = .004. The likelihood of surgery decreased with increased distance from the orbital apex in medial abscesses (OR:.92, 95%CI: 0.86-0.98, p = .009). CONCLUSION: In the pediatric population, SPOA is a serious consequence of sinusitis. This study provides evidence supporting that larger abscess size is a significant risk factor for requiring surgery. The appeal of our study is that it provides evidence and support that employ clinical parameters already assessed as standard practice in evaluating these patients. In summarizing the clinical translational relevance of our study, when determining whether to treat a patient with surgery and antimicrobial/medical therapy vs. non-surgical medical therapy alone, the clinician should focus on size of 0.510 cm3 or larger for abscesses in any location as a relative indication for surgery.

Lesion-Mapping Software for the Measurement of Subperiosteal Abscess Volume for Pediatric Orbital Cellulitis: A Retrospective Chart Review.

INTRODUCTION: Our objective was to assess the utility of using lesion-mapping software to calculate precise orbital volumes to predict patients who would benefit from early surgical intervention. METHODS: We retrospectively reviewed patients diagnosed with subperiosteal orbital abscess (SPOA) secondary to sinusitis at a tertiary pediatric hospital from 2005 to 2016. Diagnoses were confirmed by CT scans. Lesion-mapping software was used to measure SPOA volume using initial CT images. Data collected included patient demographics, length of hospital stay, and subsequent medical or surgical treatment. RESULTS: Thirty-three (52%) patients ultimately underwent surgical intervention, while 30 (48%) were managed medically. Between the surgical and medical groups, there were no differences in gender, age, or comorbidities. The surgical group had larger abscess volumes than the medically managed group (0.94 mL vs. 0.31 mL, p < 0.01). Overall, increased SPOA volume was associated with increased age (Pearson's coefficient = 0.374, p ≤ 0.01) and increased total days of intravenous (IV) antibiotic administration (Pearson's coefficient = 0.260, p = 0.039). Patients who underwent surgery on the day of admission had 25% shorter hospital stay than patients who had delayed surgery (p < 0.01). Our calculated sensitivity-optimized SPOA volume cutoff of 0.231 mL yielded sensitivity of 90.9% and specificity of 70.0%. CONCLUSIONS: This is the first study to use lesion-mapping software for precise calculation of SPOA volumes, which can help refine indications for early surgical intervention and help decrease length of hospital stay.

Redefining Success by Focusing on Failures After Pediatric Hypoglossal Stimulation in Down Syndrome.

OBJECTIVES/HYPOTHESIS: Patients with Down syndrome have a high incidence of obstructive sleep apnea (OSA) and limited treatment options. Hypoglossal stimulation has shown efficacy but has not yet been approved for pediatric populations. Our objective is to characterize the therapy response of adolescent patients with down syndrome and severe OSA who underwent hypoglossal stimulation. STUDY DESIGN: Prospective longitudinal trial. METHODS: We are conducting a multicenter single-arm trial of hypoglossal stimulation for adolescent patients with Down syndrome and severe OSA. Interim analysis was performed to compare objective sleep and quality of life outcomes at 12 months postoperatively for the first 20 patients. RESULTS: The mean age was 15.5 and baseline AHI 24.2. Of the 20 patients, two patients (10.0%) had an AHI under 1.5 at 12 months; nine patients of 20 (45.0%) under five; and 15 patients of 20 (75.0%) under 10. The mean decrease in AHI was 15.1 (P < .001). Patients with postoperative AHI over five had an average baseline OSA-18 survey score of 3.5 with an average improvement of 1.7 (P = .002); in addition, six of these patients had a relative decrease of apneas compared to hypopneas and seven had an improvement in percentage of time with oxygen saturation below 90%. CONCLUSIONS: Patients with persistently elevated AHI 12 months after hypoglossal implantation experienced improvement in polysomnographic and quality of life outcomes. These results suggest the need for a closer look at physiologic markers for success beyond reporting AHI as the gold standard. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:1663-1669, 2021.

Predictive Utility of the Penetration-Aspiration Scale in Inter-Arytenoid Injection Augmentation.

OBJECTIVES/HYPOTHESIS: To determine the utility of preoperative penetration-aspiration scale (PAS) scores and clinical findings on modified barium swallow (MBS) in predicting advancement of diet after interarytenoid injection augmentation (IAIA). STUDY DESIGN: Retrospective review. METHODS: In this retrospective cohort study, 372 consecutive patients who underwent IAIA for pharyngeal dysphagia between 2009 and 2019 were initially identified. Patients were excluded from the study if they had insufficient preop MBS, no postop MBS within 3 months of injection, supraglottoplasty, or underlying neurological condition. Ninety-three patients were included in the study. Pre- and postoperative PAS scores were recorded, as were pre and postop diets. PAS scores were calculated by a single pediatric speech and language pathologist. RESULTS: Average PAS score on MBS was 5.87 (standard deviation [SD] 2.74); median (range) = 8 (1-8). Postop average was 4.29 (SD 3.02); median (range) = 2 (1-8), P < .001. Those with worse preop PAS scores had increased odds of improvement in diet (odds ratio 1.24, 95% confidence interval [CI] 1.02-1.49, P = .029). An improvement in PAS score of 3.0 or greater predicted an improvement in diet with a sensitivity of 76.7% and a specificity of 85.7%. CONCLUSIONS: PAS score on MBS can be a useful tool when assessing pediatric patients who may be candidates for IAIA. Prospectively comparing PAS score in patients post-IAIA to patients solely undergoing diet modification can help to better objectively assess differences in outcomes and understand the full utility of PAS score.

Cost benefit of coblation versus electrocautery adenotonsillectomy for pediatric patients.

INTRODUCTION: Coblation and electrocautery are two common techniques used for adenotonsillectomy (T&A). Numerous studies have assessed surgical outcomes of coblation versus electrocautery and overall, postoperative complications are similar with the exception of a decrease in patient reported postoperative pain for coblation. Instrumentation required for coblation is significantly more expensive than that required for electrocautery. With minimal outcome differences, justification for the additional instrumentation costs is difficult. We performed this study to assess if there is a difference between operative & postoperative costs of electrocautery and coblation. METHODS: 300 patient medical records were reviewed from 2015 to 2017 with equal numbers of electrocautery and coblation surgeries. Outcome measures included finance information, duration and cost of OR and Phase I and Phase II post-anesthesia care unit (PACU), in-hospital pharmacy costs, and postoperative complications. Logistic regression was used for analysis. RESULTS: The median patient age for each surgical technique was 6 years old. Electrocautery resulted in more time in the OR compared to coblation, (OR:1.11,95%CI:1.07-1.15, p < .001), with greater associated costs, p < .001. Electrocautery patients were under anesthesia longer and had a longer surgical duration, p < .001. These same patients had longer duration in Phase II PACU, p = .028, and were given pain medications an increased number of times, p < .001. Total costs including operative expense, physician charges, OR and anesthesia times, pharmacy, and instrument were significantly higher for electrocautery patients, p = .003. There were no differences in ED visits, post-tonsillectomy bleed, or additional surgery between techniques, p > .05. CONCLUSION: T&A electrocautery technique was found to have increased overall indirect costs. Costs of instrumentation in addition to increased operative time, use of analgesics and post-operative care contribute to costs associated with electrocautery and coblation should be used when assessing surgical costs.
