Measuring the Impact of a Delay in Care on Pediatric Otolaryngologic Surgery Completion.

Objective: To determine if postponement of elective pediatric otorhinolaryngology surgeries results in a change in overall healthcare utilization and if there is any commensurate impact on disease progression. Methods: We identified patients ≤18 years of age whose surgeries were postponed at the onset of the COVID-19 pandemic-related shutdown. We then tracked patients' rate of and patterns of rescheduling surgery. Surveys were also sent to caregivers to better characterize his/her decision regarding moving forward with his/her child's surgery during COVID-19. Results: A total of 1915 pediatric patients had elective surgeries canceled, of which 992 (51.8%) were rescheduled within 4 months. No difference in rates of rescheduling was identified based on race or ethnicity. Patients who were scheduled for tonsillectomies and/or adenoidectomies were 1.22 times more likely to reschedule compared to those patients with other planned procedures (CI: 1.02-1.46). A total of 95 caregivers at two hospitals completed surveys: 44 (47.4%) rescheduled their child's surgery. Most caregivers who rescheduled were concerned their child's disease could impact their future (n = 14, 32%). Conclusions: Just over half of patients who had pediatric otolaryngologic surgery canceled during a period of social distancing went on to have surgery within a 4-month timeframe. This reflects the dependence of pediatric otolaryngologic surgery on environmental exposures and may represent a potential target for prevention and management of some pediatric otolaryngology diseases.

Combined laryngeal cleft injection laryngoplasty and salivary botulinum toxin for saliva aspiration.

Objectives: Children with type I laryngeal clefts and sialorrhea can have posterior drooling, aspiration of oral secretions, and respiratory complications. Laryngeal cleft injection laryngoplasty (LCIL) and salivary botulinum injections (Sal-Bot) have been used separately for short-term treatment of type I laryngeal clefts and sialorrhea. Our goal was to evaluate combined LCIL and Sal-Bot and create recommendations for further treatment based on response to initial treatment. Methods: Retrospective chart review of nine patients who underwent direct laryngoscopy and bronchoscopy with combined LCIL and Sal-Bot from 2012 to 2019. Charts were reviewed for patient characteristics, response to treatment, and pre and post-op hospitalizations. Subsequent procedures were performed depending on efficacy of initial treatments. Results: Nine patients were identified. All had pre-existing neurologic conditions, gastrostomy tubes, and a history of coughing and choking on secretions. Only one patient was able to feed orally (purees). 1 U/kg of botulinum toxin per gland was injected into each parotid and submandibular gland. The average units of botulinum toxin injected was 67 U. The mean laryngeal cleft injection volume was 0.35 cc. Subsequent treatment was based on timing of symptomatic improvement and individual patient factors. Five patients had respiratory-related hospitalizations in year preceding the procedures (median 1.5, range 1-10). Three (60%) had a reduction in respiratory-related hospitalization 1 year post procedure (median 1, range 1-3). One patient died during the follow up period due to continued chronic respiratory failure. Conclusions: This is the first study of combined laryngeal cleft injection laryngoplasty and botulinum toxin injections for patients with posterior laryngeal penetration and aspiration of oropharyngeal secretions. We highlight strategies for choosing subsequent procedures based on response to initial treatment. Level of Evidence: 4.

Differing rates of fungi in sinonasal cultures from pediatric sinusitis patients.

OBJECTIVES: Pediatric chronic rhinosinusitis (PCRS) is a unique clinical entity and the underlying source of inflammation is unknown. Certain subgroups, such as children with nasal polyps and cystic fibrosis (CF) sinusitis are often recalcitrant to standard medical PCRS treatments that target bacterial inflammation. Fungal infection and allergy to fungal proteins drive inflammation in other airway diseases, resulting in chronic inflammation of both the upper and lower airways. However, there is limited understanding of the role of fungi in the pathophysiology of PCRS. The objective of this study is to define the frequency of fungal infection in pediatric CRS patients, hypothesizing that certain subgroups may have more frequent positive fungal sinus cultures than other subgroups of pediatric sinusitis. METHODS: Retrospective study of patients undergoing sinus surgery at a tertiary care pediatric hospital to determine the period prevalence of positive fungal cultures in subgroups of patients. RESULTS: 400 children from 2012 to 2019 were included. 265 patients had surgical culture results available. Of the 52 patients with CF 11 (21%) had positive fungal sinus cultures. Similarly, 28% of the 25 patients with non-CF nasal polyps had positive cultures. Only 8.2% of 110 CRS without polyps patients had positive cultures, significantly fewer than other subgroups (X2 (1, N = 240) = 17.22, p < 0.01). CONCLUSION: Children with CF and children with nasal polyps had more frequent positive fungal cultures than children without nasal polyps having sinus surgery. This confirms that pediatric CF and pediatric CRS with polyps represent unique populations to study the impact of fungal infection in CRS. Further research is required to determine if these fungi represent colonization or contribute to the inflammatory environment of the airways.

Extracapsular versus intracapsular tonsillectomy: Outcomes in children with a focus on developmental delay.

INTRODUCTION: Outcomes following intracapsular tonsillectomy (IT) have not been well established in children with developmental delays. The objective of this study was to compare outcomes and complications between intracapsular and extracapsular tonsillectomy (TT) in pediatric patients with developmental delay (DD) in comparison to non-developmentally delayed children. METHODS: This is a retrospective study of pediatric patients with DD undergoing tonsillectomy between 2016 and 2019 at a tertiary care hospital. This group included patients with Down Syndrome, Autism Spectrum Disorder, other genetic syndromes, and patients with a diagnosis of global developmental delay. Outcomes and complications were analyzed for IT and TT. RESULTS: 2267 charts were reviewed, and 320 patients were identified with DD. Of those, 72 patients underwent IT and 248 underwent TT. In the DD cohort, the IT group had a shorter length of stay (0.97 vs 1.7 days, p < .0001) and was less likely to receive post-operative narcotic medication (2.8% vs 35%, p < .0001) and corticosteroids (9.7% vs 64%, p < .0001) during their hospital stay. Reductions in emergency room (ER) visits (5.6% vs 10%, p = .21) and post-op bleeding (PTH) (1.4% vs 4.8%, p = .31) for IT vs TT were not statistically significant in the DD group. In the NDD group, fewer patients undergoing IT returned to the ER (11% vs 2.3%, p < .0001) or had PTH (4.8% vs 0.25%, p, 0.0001) as compared to those children undergoing TT. There was no difference between parental report of symptom improvement between the groups (39% vs 33%, p = .39). Analysis of 180 patients with preoperative and postoperative sleep study data revealed post-op Apnea Hypopnea Index (AHI) improved with both techniques (74% TT vs 79% IT, p = .7). There were no differences noted for persistent obstructive sleep apnea (OSA) among the two techniques for both study groups (p = .63). CONCLUSION: Children with DD undergoing IT have reduced length of stay and reduced inpatient administration of post-operative opioids and steroids. IT has comparable efficacy to TT in treating symptoms of pediatric sleep apnea with a better safety profile. Overall, children undergoing IT return to the operating room less frequently than those undergoing TT. Longer follow-up studies will be needed to evaluate rate of tonsil regrowth, risk of revision surgery and persistence of OSA in these patients.

Volumetric brain magnetic resonance imaging analysis in children with obstructive sleep apnea.

OBJECTIVES: Pediatric Obstructive Sleep Apnea (OSA) is associated with neurocognitive deficits. Cerebral structural alterations in the frontal cortex, cerebellum, and hippocampus have been reported in adult OSA patients. These brain areas are important for executive functioning, motor regulation of breathing, and memory function, respectively. Corresponding evidence comparing cerebral structures in pediatric OSA patients is limited. The objective of this study is to investigate MRI differences in cortical thickness and cortical volume in children with and without OSA. STUDY DESIGN: Prospective, single institutional case-control study. METHODS: Forty-five children were recruited at a pediatric tertiary care center (27 with OSA; mean age 9.9 ± 1.9 years, and 18 controls; mean age 10.5 ± 1.0 years). The OSA group underwent magnetic resonance imaging (MRI), polysomnography (PSG) and completed the Pediatric Daytime Sleepiness Scale (PDSS) and the Child's Sleep Habits Questionnaire (CSHQ). High-resolution T1-weighted MRI was utilized to examine cortical thickness and gray and white matter volume in children with OSA compared to a healthy group of demographically-comparable children without OSA selected from a pre-existing MRI dataset. RESULTS: Children with OSA showed multiple regions of cortical thinning primarily in the left hemisphere. Reduced gray matter (GM) volume was noted in the OSA group in multiple frontal regions of the left hemisphere (superior frontal, rostral medial frontal, and caudal medial frontal regions). Reduced white matter (WM) volume in both the left and right hemisphere was observed in regions of the frontal, parietal, and occipital lobes in children with OSA. CONCLUSION: This study noted differences in cortical thickness and GM and WM regional brain volumes in children with OSA. These findings are consistent with other pediatric studies, which also report differences between healthy children and those with OSA. We found that the severity of OSA does not correlate with the extent of MRI alterations.

The importance of sublingual gland removal in treatment of ranulas: A large retrospective study.

PURPOSE: Investigate the efficacy of sublingual gland removal for the treatment of simple and plunging ranulas. MATERIALS AND METHODS: After IRB approval, a retrospective review was performed on patients treated for a ranula from February 2013 to May 2018 at Texas Children's Hospital in Houston, TX. Clinical data was collected from medical records and patients were contacted in November 2018 to obtain additional information about recurrences or complications. RESULTS: This study included 52 patients with ranulas (10 plunging, 42 simple; M:F 21:31) with a mean age of 9.68 years. Eighteen patients provided information in the extended follow-up period. Simple ranulas were treated with intraoral excision of the cyst and the sublingual gland (27 cases), marsupialization (7 cases), intraoral excision of the cyst alone (7 cases), and intraoral excision of the cystic component and subsequent marsupialization after recurrence (1 case); intraoral excision of the sublingual gland was not associated with any recurrence. Plunging ranulas were treated with intraoral excision of the cyst and/or sublingual gland (7 cases) or with a transcervical approach (3 cases). One patient was initially treated with sclerotherapy before undergoing intraoral excision of the sublingual gland. Two patients treated with transcervical excision of the cyst experienced recurrence compared to no recurrence with intraoral excision of the sublingual gland. CONCLUSION: Intraoral removal of the sublingual gland is the most effective treatment for both simple and plunging ranulas. Plunging ranulas must be considered in patients presenting with a submandibular and submental cystic mass given intraoral extension may not be apparent.

Screening for undiagnosed bleeding disorders in post-tonsillectomy bleed patients: Retrospective review and systematic review of the literature.

OBJECTIVES: There is currently no standard for screening children with post-tonsillectomy bleeds (PTB) for coagulopathy disorders. This study aims to identify children with occult coagulopathy diagnosed at PTB and to identify factors associated with diagnosis. A systematic review of the literature further identified trends in this topic. METHODS: A retrospective chart review of patients returning to the operating room for PTB at a tertiary children's hospital was undertaken from 2012 to 2016. A systematic review using Medline OVID was subsequently performed. RESULTS: Of 12,503 tonsillectomies, 311 children (52% male, mean age 8 years) required surgery for PTB (2.5% rate). Twenty-one patients (7%) had multiple episodes. Only two patients (0.6%) (both with known coagulopathy) underwent pre-tonsillectomy labs and 260 (84%) had labs at PTB. Six patients (2%) were diagnosed with a new coagulopathy, most commonly von Willebrand's Disease (vWD) in five (2%). Three patients (1%) were diagnosed at first PTB and three (1%) at second PTB. Of the three diagnosed at second PTB, two had normal partial thromboplastin time (PTT). In systematic review, 1243 manuscripts were reviewed and 8 papers discussing this topic are presented. CONCLUSION: Occult coagulopathy was rarely diagnosed at PTB, but this may be limited by inconsistent screening. PT and PTT are not sensitive tests for vWD, and normal coagulation labs may lead to delayed diagnosis. The literature reveals occult coagulopathy is rare but often diagnosed after severe or recurrent hemorrhage. In order to provide efficient care and medical management, a standardized algorithm and sensitive labs for screening PTB patients are needed.
