Otolaryngologic conditions in children with neonatal abstinence syndrome: A descriptive study

Literature on otolaryngologic sequelae of children with neonatal abstinence syndrome (NAS) has been scarce to date. Prior reports suggest some otologic conditions associated with long-term NAS outcomes, but no comprehensive exploration of these relationships currently exists. This study aims to characterize the breadth of otolaryngologic conditions diagnosed in children with NAS.

This is a retrospective descriptive study conducted at a tertiary care hospital. We identified 524 children with NAS born between 1/1/2014 and 12/31/2019 who were evaluated by the otolaryngology department. Diagnoses were categorized as otologic, oropharyngeal, sinonasal, and laryngeal. Additional diagnoses of obstructive sleep apnea (OSA) and congenital abnormalities of head and neck were noted separately. Descriptive statistics were calculated, and ANCOVA testing analyzed for differences in mean number of diagnoses.

680 total otolaryngologic diagnoses were analyzed across 524 patients. Otologic conditions comprised 39.7 % of total diagnoses, oropharyngeal conditions 26.8 %, sinonasal conditions 18.4 %, laryngeal conditions 5.3 %, OSA 1.5 %, and congenital abnormalities 8.3 %. After adjusting for covariates, there were a significantly higher number of otologic diagnoses compared to the other subcategories with mean (standard deviation) of 0.46 (0.83), followed by oropharyngeal 0.35 (0.55), sinonasal 0.24 (0.49), and laryngeal 0.07 (0.29). Thirty total otolaryngology-related procedures were performed in our sample, with myringotomy with tube insertion as the most common.

Understanding the otolaryngologic sequelae of children with NAS is important as these conditions impact children's early development. Our study also highlights various socioeconomic factors that may impact pediatric ENT care and the follow-up of patients born with NAS.
