The Impact of Obstructive Sleep Apnea on the Development of Refractory Nasal Symptoms After Adenoidectomy

Objectives: Chronic rhinitis may contribute to a persistently decreased quality of life in patients undergoing surgical treatment for obstructive sleep apnea (OSA). This study aimed to characterize the role of OSA in pediatric patients with refractory chronic rhinitis after adenoidectomy.Methods: We reviewed the charts of patients <18 years of age with a history of OSA who underwent adenoidectomy at an academic medical center from October 2012 to December 2018 and that were seen in the clinic for follow-up. They were identified through the Current Procedural Terminology (CPT) codes 42830 and 42831 with the exclusion of CPT 42820 for tonsillectomy and adenoidectomy. Patients with a prior diagnosis of OSA who had refractory symptoms were compared with those who had symptoms resolution using chi-square analysis and t-tests.Results: Thirty-six (35.0%) patients with refractory symptoms following adenoidectomy and 52 (37.4%) patients without refractory symptoms had a history of OSA before surgery (p=0.80). In patients with refractory symptoms, the average age (3.8 years) and male sex (n=24, 66.7%) did not differ significantly from the age (4.42 years) and male sex (n=36, 69.2%) percentages of patients without refractory symptoms. The mean apnea/hypopnea-index (AHI) (p=0.91), completion of the sleep study (p=0.41), history of snoring (p=0.92), and tonsil size (p=0.42) did not differ significantly between the groups. However, patients with refractory symptoms had a significantly higher mean body mass index (BMI) (19.58) than those who did not (17.77, p=0.04) and completed a higher number of allergy evaluations (p=0.02).Conclusions: While the history and severity of OSA did not differ significantly in patients with refractory nasal symptoms after adenoidectomy, these patients had a significantly higher BMI and completion of allergy evaluation.
