Pandemics and pediatric otolaryngology.

The objective is to describe how the COVID pandemic changed the epidemiology and management of pediatric otolaryngologic diseases, which may influence clinical decision-making in the future. Many changes were made to the structure of healthcare delivery to minimize transmission of coronavirus. As a result, there was a widespread adoption of telehealth. Additionally, guidelines were published with new protocols for evaluation and management of common pediatric otolaryngologic conditions, which in many circumstances, delayed or replaced surgical intervention. Now, as we evaluate the impact of these clinical changes, we have gained new understanding about the pathophysiology of certain pediatric conditions, namely otitis media, for which upper respiratory infection exposure may play a larger role than previously thought. As we have altered practice patterns for common pediatric otolaryngologic conditions, we recognize that ongoing research may help us determine if surgical interventions have been overutilized in the past and help guide clinical practice guidelines moving forward.

Genetic Testing Leading to Early Identification of Childhood Ocular Manifestations of Usher Syndrome.

OBJECTIVES: Hearing-loss gene panel testing (HLGPT) is increasingly accessible as a first-line test in determining the etiology of sensorineural hearing loss (SNHL) in children. A major advantage of HLGPT is early identification of syndromic forms of SNHL, especially Usher syndrome, prior to the development of overt syndromic phenotype, which may impact management and counseling. Here, we describe early ocular findings in children with clinically non-syndromic SNHL identified by HLGPT as having two variants associated with Usher Syndrome. METHODS: A total of 184 children, ages 1 month - 15 years of age, evaluated at one tertiary pediatric children's hospital for clinically non-syndromic SNHL, underwent next-generation sequencing of 150 genes involved in hearing loss. Children with two variants in genes associated with Usher syndrome were referred for evaluation by pediatric ophthalmology. RESULTS: A total of 18/184 tested children had two variants in Usher syndrome-associated genes, including MYO7A, GPR98 (ADGRV1), USH2A, and PDZD7. SNHL varied from moderate to profound. 29% of the children who underwent clinical ophthalmology evaluation were found to have previously unidentified retinal abnormalities on retinal imaging or electroretinography consistent with inherited retinal degeneration. CONCLUSION: Among this ethnically and racially diverse pediatric population with apparently non-syndromic SNHL, HLGPT yielded a high proportion (10%) of children with two variants in genes associated with Usher syndrome. Early genetic testing allows early identification of variants conferring a diagnosis of Usher syndrome at a stage prior to visual symptoms. This allows for more informed genetic counseling, reproductive planning, and sensory deficit interventions. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2053-E2059, 2021.

Endoscopic percutaneous suture lateralization for neonatal bilateral vocal fold immobility.

OBJECTIVE: Bilateral vocal-fold immobility (BFVI) is a rare but significant cause of severe respiratory distress in neonates. The primary aim of treatment is to provide an adequate airway while minimizing adverse effects such as aspiration and dysphonia. Our objective here is to describe the outcomes of a series of neonates undergoing percutaneous endoscopic suture lateralization for BVFI using a novel technique. METHODS: In this retrospective case series, we present 6 neonates (mean age: 18 days) with BVFI from three tertiary academic medical centers. The etiologies included 4 idiopathic, 1 unspecified neurodegenerative disorder, and 1 acquired from cardiac surgery. All had stridor and respiratory distress with hypoxemia requiring respiratory support at diagnosis. Endoscopic vocal-fold lateralization was performed under spontaneous-breathing suspension laryngoscopy using a novel technique of percutaneous needle-directed placement of 4-0 prolene suture without use of specialized equipment. RESULTS: All patients had clinical improvement in stridor and respiratory support requirements and avoided tracheostomy. One patient had persistent aspiration after lateralization that resolved after suture removal. One patient required bilateral lateralization procedures. One patient expired of epilepsy due to neurodegenerative disease unrelated to airway pathology. At last follow-up (mean 12.6 months), 5/5 remaining patients were on room air without tracheostomy and feeding orally without aspiration; 4/5 had partial or complete return of vocal-fold function. CONCLUSION: Endoscopic percutaneous suture lateralization may be a safe and effective non-destructive primary treatment modality for neonatal BVFI. All neonates undergoing this procedure avoided tracheotomy.

Risk factors associated with postoperative tympanostomy tube obstruction.

IMPORTANCE: Myringotomy and tympanostomy tube placement for chronic otitis media with effusion is the most common reason for a child to undergo anesthesia in the United States. Postoperative tube obstruction occurs in 1.4% to 36.0% of cases and remains a challenge in achieving middle ear ventilation. OBJECTIVE: To identify risk factors associated with tube obstruction. DESIGN, SETTING, AND PARTICIPANTS: Retrospective medical record review of 248 patients, mean age 2.54 years, seen between March 2007 and June 2011 in a tertiary care pediatric hospital. INTERVENTIONS: Tympanostomy tube placement and postoperative otic drop therapy. MAIN OUTCOMES AND MEASURES: Tube patency at postoperative visit, number of tube removals and revisions, age, sex, body mass index (BMI), middle ear fluid type at time of surgery, and time between surgery and first postoperative visit were examined. Type of surgery (tympanostomy tube placement alone, adenoidectomy + tympanostomy tube placement, tympanostomy tube placement + adenoidectomy + tonsillectomy) and its effect on tube patency were also reviewed. RESULTS: At first follow-up, 10.6% of patients had occlusion of one or both tubes. No significant association was found between tube patency and a patient's BMI percentile, sex, or procedure type. Patients with no middle ear fluid were more likely to have patent tubes than those who had serous fluid (odds ratio [OR], 3.5; 95% CI, 1.2-10.6; P = .02). A significant inverse correlation was found between patency and time between surgery and follow-up in that patients who had longer follow-up after surgery were less likely to have patent tubes (OR per day of follow-up delay, 0.990; 95% CI, 0.981-0.999; P = .01). CONCLUSIONS AND RELEVANCE: Tympanostomy tube obstruction was seen in 10.6% of patients. Serous fluid and increased time to postoperative visit were statistically significant indicators for tube occlusion.

Deep neck infections.

Deep neck space infections are commonly seen and managed across various medical and surgical specialties. Common presentations permit straightforward management but still pose the risk of severe complications sometimes even with appropriate management. This article emphasizes the anatomic and physiologic process to heed when managing children with deep neck infections. The roles of radiography and medical versus surgical management are discussed.
