ABSTRACT
INTRODUCTION: Vagal nerve stimulator (VNS) implantation is a vital therapy for epilepsy refractory to other treatments; however, it is associated with a very high rate of voice changes. Relatively few of these patients are evaluated for vocal fold motion impairments. In this series, we evaluate 5 such patients with a novel phenotype of forced abduction with VNS stimulation. METHODS: Retrospective case series. RESULTS: Five patients with a VNS implant who underwent operative direct or in-office rigid laryngoscopy and had vocal fold motion impairment associated with VNS activation are included. All 5 patients had vocal fold mobility with VNS off and a fixed with activation. All patients exhibited vocal fold abduction with VNS activation. Patient 2 has since undergone laryngeal reinnervation, which helped her intermittent dysphonia but left a small glottic gap. A type 1 thyroplasty corrected this gap and improved her voice further. Patient 3 has undergone laryngeal reinnervation for which early results show improvement in perceptual and patient reported outcomes. Patients 4 and 5 have both undergone laryngeal reinnervation with improvement in voice. CONCLUSION: Previous reported cases of stimulated immobility associated with VNS use describe only adduction of the vocal fold. This series expands the previous work showing the VNS activation can also cause stimulated immobility in an abducted position, for which reinnervation and other medialization procedures offer promising treatment.
ABSTRACT
OBJECTIVE: The purpose of this study was to identify risk factors for perioperative complications and long-term morbidity in infants from the neonatal intensive care unit (NICU) presenting for a tracheostomy. METHODS: This single-center retrospective cohort study included infants in the NICU presenting for a tracheostomy from August 2011 to December 2019. Primary outcomes were categorized as either a perioperative complication or long-term morbidity. A severe perioperative complication was defined as having either (1) an intraoperative cardiopulmonary arrest, (2) an intraoperative death, (3) a postoperative cardiopulmonary arrest within 30 days of the procedure, or (4) a postoperative death within 30 days of the procedure. Long-term morbidities included (1) the need for gastrostomy tube placement within the tracheostomy hospitalization and (2) the need for diuretic therapy, pulmonary hypertensive therapy, oxygen, or mechanical ventilation at 12 and 24 months following the tracheostomy. RESULTS: One-hundred eighty-three children underwent a tracheostomy. The mean age at tracheostomy was 16.9 weeks while the mean post-conceptual age at tracheostomy was 49.7 weeks. The incidence of severe perioperative complications was 4.4% (n = 8) with the number of pulmonary hypertension medication classes preoperatively (OR: 3.64, 95% CI: (1.44-8.94), p = 0.005) as a significant risk factor. Approximately 81% of children additionally had a gastrostomy tube placed at the time of the tracheostomy, and 62% were ventilator-dependent 2 years following their tracheostomy. CONCLUSION: Our study provides critical perioperative complications and long-term morbidity data to neonatologists, pediatricians, surgeons, anesthesiologists, and families in the expected course of infants from the NICU presenting for a tracheostomy.

INTRODUCTION: Sialorrhea or drooling can result in physical and psychosocial complications, such as aspiration and social isolation. Treatment options include botulinum toxin into the salivary glands and 4-duct ligation (i.e., simultaneous ligation of the bilateral parotid and submandibular ducts). This systematic review aimed to compare the efficacy and complication rates of botulinum toxin and 4-duct ligation for the treatment of drooling in children. METHODS: Following PRISMA guidelines, PubMed, Embase, Web of Science, and Cochrane Library were searched from inception through June 17, 2021 for studies examining the efficacy of botulinum toxin or 4-duct ligation for drooling in children. Data were summarized by pooled counts, percentages, and means. Complication rates were compared by a chi-squared test. RESULTS: A total of 22 studies (n = 606) examining botulinum toxin and 5 studies (n = 124) examining 4-duct ligation were included. From 12 botulinum toxin studies (n = 211), mean drooling frequency and severity scores was 7.5 at baseline. Mean difference from baseline was -2.6 (n = 92) at 4 weeks follow-up, -2.1 at 8 weeks (n = 41), -2.1 at 12 weeks (n = 56), and - 2.1 at 16 weeks (n = 58). From 4 4-duct ligation studies (n = 103), mean baseline drooling frequency and severity score was 8.4. Mean difference was -3.7 at mean follow-up of 35.6 months (n = 103). Eighteen botulinum studies (n = 343) recorded 53 (15.5 %) complications, including thickened saliva (n = 9), dysphagia (n = 4), and cheek abscesses (n = 4). Four 4-duct ligation studies (n = 108) recorded 25 (23.1 %) complications, including parotid gland swelling (n = 4), aspiration pneumonia (n = 3), and oxygen desaturation (n = 3). There was no statistically significant difference in complication rates between botulinum toxin and four-duct ligation (p = 0.065). CONCLUSION: Botulinum toxin injection and 4-duct ligation are both effective in improving sialorrhea in children and have comparable complication rates.

OBJECTIVE: To determine the utility of triple endoscopy (combined direct laryngoscopy, bronchoscopy (DLB), flexible bronchoscopy with bronchoalveolar lavage (FB + BAL), and esophagogastroduodenoscopy (EGD)) in the diagnosis and management of patients with recurrent croup (RC), and to identify predictors of endoscopic findings METHODS: A retrospective chart review was performed of pediatric patients (age <18 years) with RC evaluated by triple endoscopy at a tertiary care pediatric hospital from 2010 to 2021. Data including presenting symptoms, airway findings, BAL and EGD with biopsy findings were collected. RESULTS: 42 patients with RC underwent triple endoscopy were included. The mean age was 4.55±2.84 years old. The most common symptom was chronic cough among 19 (45%) patients, while 23 (55%) patients had gastrointestinal (GI) symptoms. Airway findings included tracheomalacia in 19, laryngeal cleft in 17, and subglottic stenosis in 11 patients. On EGD with biopsy, abnormal gross findings were present in 6 and abnormal microscopic findings in 18 patients, including 6 with histologic findings suggestive of gastroesophageal reflux and 5 with eosinophilic esophagitis. Seventeen (40%) patients had positive culture on BAL. No findings in patient histories significantly predicted presence of lower airway malacia, subglottic stenosis, or abnormal EGD findings. CONCLUSIONS: Children with recurrent croup presenting to aerodigestive centers may not have any pertinent presenting symptoms that correlate with significant findings on triple endoscopy. Further work is needed to determine which children with recurrent croup may benefit from aerodigestive evaluation. LEVEL OF EVIDENCE: Level 3.

OBJECTIVE: To provide recommendations for a comprehensive management approach for infants and children presenting with symptoms or signs of aspiration. METHODS: Three rounds of surveys were sent to authors from 23 institutions worldwide. The threshold for the critical level of agreement among respondents was set at 80 %. To develop the definition of "intractable aspiration," each author was first asked to define the condition. Second, each author was asked to complete a 5-point Likert scale to specify the level of agreement with the definition derived in the first step. RESULTS: Recommendations by the authors regarding the clinical presentation, diagnostic considerations, and medical and surgical management options for aspiration in children. CONCLUSION: Approach to pediatric aspiration is best achieved by implementing a multidisciplinary approach with a comprehensive investigation strategy and different treatment options.

OBJECTIVE: Children with tracheostomies have complex medical issues that require long-term technology dependence and continuous medical care at home. Parents of tracheostomy-dependent children often assume the majority of their child's home care leading to a shift in family dynamics and a decrease in caregiver quality of life. This systematic review sought to identify instruments to measure caregiver psychosocial outcomes after their child's tracheostomy and report on the findings. DATA SOURCES: A systematic review was performed using Medline, CINAHL, and EMBASE. REVIEW METHODS: Studies that evaluated psychosocial outcomes in caregivers of tracheostomy-dependent children were included. RESULTS: We screened a total of 1286 nonduplicate records to include a total of 12 studies assessing the psychosocial outcomes of parents of tracheostomy-dependent children. Fourteen instruments were identified. Caregivers reported lower quality of life when compared to other chronic caregiver groups. They experienced high degrees of stress, struggled to cope individually and as a family unit, and experienced decision regret and conflict. CONCLUSION: Findings from this review suggest a significant impact on caregiver psychosocial well-being, but few quantitative studies investigated this dynamic with measures validated in this caregiver population. This review demonstrates the need for longitudinal studies using validated tools to assess the long-term impacts and outcomes of caregivers of the tracheostomy-dependent child.

OBJECTIVE: To provide guidance for the comprehensive management of children referred for anterior drooling. The mission of the International Pediatric Otolaryngology Group (IPOG) is to develop expertise-based recommendations for the management of pediatric otolaryngologic disorders with the goal of improving patient care. METHODS: Survey of expert opinion by the members of the International Pediatric Otolaryngology Group (IPOG). The recommendations are derived from current expert consensus and critical review of the literature. RESULTS: Consensus recommendations include initial care and approach recommendations for health care providers who commonly evaluate children with drooling. This includes evaluation and treatment considerations for commonly debated issues in drooling management, initial work-up of children referred for anterior drooling, treatment recommendations, indications and contra-indications for rehabilitation, medical, and surgical management, as well as pros and cons of different surgical procedures in the hands of drooling management experts. CONCLUSION: Anterior drooling consensus recommendations are aimed at improving patient-centered care in children referred for sialorrhea.

Rosai-Dorfman disease (RDD) is a rare benign systemic histiocytic proliferation characterized by massive lymph node enlargement and sometimes associated with extranodal involvement. Even though it is considered to be benign, death can occur depending on the extent and location. Our case highlights a primary extranodal site of the right pinna with extension through the Eustachian tube to the subglottis. A previously healthy 15-year-old female presented with 1-year right pinna swelling, slowly enlarging and becoming more bothersome. An incisional biopsy was performed on the ear along with S100 staining yielding a diagnosis. After multidisciplinary case discussion, clofarabine monotherapy and systemic therapy for Langerhans cell histiocytosis has started. Rosai-Dorfman disease can be a general disorder, often affecting the lymph nodes. Unlike a nodal disease, extranodal disease could involve any site on the patient's anatomy. Head and neck lesions are the most common extranodal lesions. Rosai-Dorfman disease is self-limited in more than 20% of the cases with spontaneous regression without intervention; 70% of the patients have noticeable symptoms and vital organ involvement requiring treatments such as surgery, steroids, radiation, and chemotherapy. In our case, the patient had wide involvement and presented without any serious breathing difficulties; we decided to start with monotherapy with chemotherapy and systematic glucocorticoid treatment.

Drooling and aspiration of saliva can affect the quality of life and morbidity of patients with neuromuscular diseases. Practitioners must differentiate between drooling with and without aspiration of saliva, as the presence of aspiration affects respiratory health. There are several validated drooling scales, but validated assessments for aspiration of saliva are lacking. Once diagnosed, drooling can be treated with rehabilitative therapy, anticholinergics, botulinum toxin to the salivary glands, and surgery. Drooling with aspiration of saliva often requires multidisciplinary engagement to decrease the risk of respiratory complications.

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.
ABSTRACT
BACKGROUND: Pediatric cavernous sinus thrombosis (CST) is a rare condition with limited data regarding its clinical characteristics and long-term outcomes. The objective of this study was to describe the clinical and radiologic features, diagnostic evaluation, management, and long-term prognosis and to identify clinical variables associated with long-term outcomes in pediatric CST. METHODS: A retrospective chart review of patients younger than 18 years diagnosed with a CST between 2004 and 2018 at a single center was conducted. RESULTS: We identified 16 (M:F = 10:6) children with CST with a mean age of 7.6 years (10 days to 15 years) and average follow-up duration of 29 months (3 weeks to 144 months). The most common symptom and examination finding at presentation was eyelid swelling (n = 8). Six patients had bilateral CST. The most common etiologies were sinusitis (n = 5) and orbital cellulitis (n = 5). Treatments included antibiotics (n = 14), anticoagulation (n = 11), and surgery (n = 5). Only one patient died due to intracranial complications. Twelve patients had a normal examination at follow-up. None of the clinical variables including age (P = 0.14), gender (P = 0.09), use of antibiotics (P = 1.00) or anticoagulation (P = 1.00), surgery (P = 0.28), parenchymal abnormalities (P = 0.30), additional cerebral venous thrombosis (P = 0.28), and early versus late commencing of anticoagulation (P = 1.00) were significant when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging. CONCLUSIONS: Our study is one of the largest cohorts with the longest follow-up data for the pediatric CST. Most of our patients had favorable outcomes at follow-up. We found no statistical difference between clinical variables when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging.

OBJECTIVES/HYPOTHESIS: To analyze tracheostomy-related complications in pediatric patients with scoliosis. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective chart review of all patients with tracheostomy and scoliosis was performed at a single institution. The charts were reviewed for variables including difficulties with tracheostomy tube changes, poor positioning of tube, abnormal appearance of trachea, and emergency room visits and admissions for complications. Decannulation rates were also identified. RESULTS: About 102 patients met inclusion criteria, 96 (94.1%) had scoliosis involving the thoracic spine, and 4 had scoliosis involving the cervical spine; 13 (12.8%) patients had documented poor positioning on tracheoscopy; 31 patients (30.3%) had at least one emergency room visit or admission for complications, such as accidental decannulation or bleeding from the tracheostomy; 19 (18.6%) patients required at least one tube change due to poor positioning, with 7 (6.9%) requiring multiple changes; 18 (17.7%) had reported difficulties with home tube changes. Custom length tubes were required in 9 patients (8.8%). The level of scoliosis was not associated with any of these complications. Abnormalities of the trachea, such as tortuosity, obstructive granulomas, or tracheomalacia, were seen in 35 patients (34.3%) on bronchoscopy. Scoliosis repair was performed in 18 patients (17.65%), of which two achieved decannulation. Ten patients (9.8%) overall were decannulated. CONCLUSION: A portion of patients with scoliosis who are tracheostomy-dependent have anatomical abnormalities of the trachea and poor positioning of the tracheostomy tube. Decannulation rates are also lower in this population compared to the literature. Further work is required to elucidate if scoliosis predisposes patients toward tracheostomy-related complications.

OBJECTIVES: Implanted vagal nerve stimulators (VNS) are an accepted therapy for refractory seizures. However, VNS have been shown to affect vocal fold function, leading to voice complaints of hoarseness. We present a case of intermittent VNS-related vocal fold paralysis leading to dysphonia and dysphagia with aspiration in a pediatric patient. METHODS: This is a case report of a patient at a tertiary hospital evaluated in pediatric swallow and voice clinics. Patient and mother gave verbal consent to be included in this case report. RESULTS: Indirect laryngeal stroboscopy was performed demonstrating full vocal fold mobility with VNS off and left vocal fold paralysis in lateral position and glottic gap with VNS on. Voice measures were performed demonstrating decreased phonation time, lower pitch, and decreased intensity of voice with VNS on. Flexible endoscopic evaluation of swallowing demonstrated deep penetration alone with VNS off and deep penetration with concern for aspiration with VNS on. CONCLUSIONS: While the majority of cases of vocal fold movement impairment associated with VNS have been noted to have a medialized vocal fold with VNS activation, we describe a case of intermittent vocal fold lateralization associated with VNS activation with resultant voice changes and aspiration.

Elevated immunoglobulin E (IgE) levels can be associated with infectious, allergic and inflammatory disorders, and rarely as a manifestation of an inborn error of immunity. Here we report the case of an adolescent female who presented with a gradually enlarging neck mass, lymphadenopathy, eosinophilia and highly elevated IgE levels. Laboratory and histopathologic evaluation revealed an unlikely diagnosis of Kimura Disease. We discuss the differential diagnosis of a neck mass with prominent eosinophils on histology, and review support for T-helper type 2 (Th2) cell activation and hyper-IgE in Kimura Disease.
ABSTRACT
IMPORTANCE: Persistent velopharyngeal insufficiency (VPI) is a rare but well-recognized complication of adenoidectomy. VPI can have a significant impact on the communication of a child. OBJECTIVE: To describe the pathophysiology of post-adenoidectomy VPI, identify its associated risk factors, and illustrate the techniques used to treat the entity. EVIDENCE REVIEW: A search of English or translated English articles concerning adenoidectomy, partial adenoidectomy, superior adenoidectomy; and velopharyngeal insufficiency, speech and voice from 1980 to 2021 was performed using Pubmed and Embase. Data from prospective and retrospective studies and their relevant references were pooled. RESULTS: By objective measures, hypernasality is noted in many pediatric patients post-adenoidectomy, but this typically resolves in 3-6 months. Risk factors for the development of post-adenoidectomy VPI include low birth weight, family history of hypernasality, and history of speech problems or nasal regurgitation. The cleft palate, submucous cleft palate, poor palate mobility, and a deep pharynx may indicate susceptibility to VPI. Speech therapy is successful in up to 50% of patients, while surgical intervention may be tailored based on the diagnostic evaluation of the velopharynx with videofluoroscopy or nasoendoscopy. CONCLUSION: We present a comprehensive review of the literature on the pathophysiology, risk factors, and treatment of post-adenoidectomy VPI. We hope to bring awareness to the factors that can lead to a rare but potentially devastating complication in one of the most common procedures performed by Otolaryngologists.

OBJECTIVE: To compare measurements of the pediatric subglottis obtained by surgeon-performed ultrasound and endoscopy. STUDY DESIGN: Prospective observational comparison-of-methods study. SETTING: Tertiary care pediatric hospital. SUBJECTS AND METHODS: Thirty-one patients who underwent direct laryngoscopy from May 2017 to July 2018 were recruited. Transcervical ultrasound was used to visualize the vocal folds, subglottis, and cervical trachea. The anterior-posterior (AP) and transverse (TV) diameter of the subglottic space were measured endoscopically and via ultrasound by 2 independent evaluators. Measurements were compared for correlation, bias, and agreement. A clinically acceptable bias for subglottic diameter was assumed to be 0.5 mm or less. RESULTS: The median age of enrolled patients was 2.6 years (range, 4 months-13.3 years). Endoscopic subglottic AP and TV measurements ranged from 3.33 mm to 14.81 mm and from 4.44 mm to 11.65 mm, respectively, while ultrasonographic AP and TV measurements ranged from 4.57 mm to 9.85 mm and from 3.77 mm to 8.96 mm. Pearson coefficient showed strong a correlation for both endoscopic and ultrasound AP (R = 0.8081, P < .0001) and TV (R = 0.8796, P < .001) measurements of the subglottis. Bland-Altman plots revealed a bias (average discrepancy) for AP measurements of 0.22 mm and 0.11 mm for TV measurements. CONCLUSION: Endoscopic and ultrasonography measurements of the pediatric subglottic airway were strongly correlated. The discrepancy between AP and TV measurements was less than 0.5 mm. Ultrasound of the subglottis may be an alternative to endoscopic assessment of the airway for measurement of the subglottic airway in children in select cases.

BACKGROUND: Mandibular distraction osteogenesis (MDO) is the primary surgical intervention to treat airway obstruction in Pierre Robin sequence (PRS). Current morphologic studies of PRS mandibles do not translate into providing airway management decisions. We compare mandibles of infants with nonsyndromic PRS to controls characterizing morphological variances relevant to distraction. We also examine how morphologic measurements and airway grades correlate with airway management. METHODS: Patients with PRS under 2 months old were age and sex matched to controls. Demographic and perioperative data, and Cormack-Lehane airway grades were recorded. Computed tomography scans were used to generate mandibular models. Bilateral condylions, gonions, and the menton were identified. Linear and angular measurements were made. Wilcoxon rank sum and 2-sample t tests were performed. RESULTS: Twenty-four patients with PRS and 24 controls were included. Seventeen patients with PRS required MDO. PRS patients had shorter ramus heights (16.7 vs 17.3 mm; P = .346) and mandibular body lengths (35.3 vs 39.3 mm; P < .001), more acute gonial angles (125.3° vs 131.3°; P < .001), and more obtuse intergonial angles (94.2° vs 80.4°; P < .001) compared to controls. No significant differences were found among patients requiring MDO versus conservative management nor among distracted patients with high versus low airway grades. CONCLUSION: Our study examines the largest and youngest PRS population to date regarding management of early airway obstruction with MDO. Our findings indicate that univector mandibular body distraction allows for normalization in nonsyndromic patients with PRS, and airway obstruction management decisions should remain clinical.

INTRODUCTION: Vocal fold movement impairment (VFMI) is a well-known sequela of cervical and thoracic procedures performed in the vicinity of the recurrent laryngeal nerve. Interpretation of flexible nasolaryngoscopy (FNL) can be difficult in young children due to crying, secretions, and obstructing supraglottic structures. We have previously published on the use of radiologist performed and interpreted, laryngeal ultrasound (LUS) to evaluate vocal fold mobility with substantial agreement with FNL in infants in the cardiovascular intensive care unit. The purpose of this study was to evaluate point of care, clinician performed, LUS for vocal fold mobility in a pediatric voice clinic. METHODS: LUS and FNL were performed and recorded on 30 consecutive patients (11 with a clinical diagnosis of VFMI and 19 with clinically normal mobility) in a pediatric voice clinic. All LUS was performed by a single clinician (reviewer 1) with a GE logiq P9 and 12â¯MHz linear probe. Deidentified recordings of the LUS and FNL (without sound) were reviewed in random order by 2 fellowship trained pediatric otolaryngologists who were blinded to the vocal fold mobility. Cohen's kappa was used to determine agreement. RESULTS: There was substantial agreement (κ â¯=â¯0.7) between the reviewers regarding interpretation of LUS as well as regarding interpretation of FNL κ â¯=â¯0.7802. In addition, each reviewer had near perfect to substantial agreement between their interpretation of the LUS and FNL (reviewer 1 κ â¯=â¯0.9294 and reviewer 2 κ â¯=â¯0.8413). CONCLUSION: Point of care, clinician performed, LUS can be used for the identification of VFMI with substantial agreement with FNL with good inter-rater reliability. This provides clinicians with another tool in their armamentarium for the evaluation of challenging larynges.

The presence of a bilobed tongue is a rare congenital malformation. There are multiple reports of a bifid anterior lobe; however, a case with complete separation of isolated anterior and posterior lobes has not been previously described. We report the case of a 2-year-old male, who presented with a V-shaped mandible and glossoptosis in the setting of respiratory distress and difficulty feeding, incidentally found to have a bilobed tongue with independent anterior and posterior lobes.
