Abstract

Objective: We sought to study adenoidectomy rates in children with adenoid hypertrophy (AH) who were either treated with medical therapy or not during a 2-year follow-up period in a longitudinal population-based study. Methods: We retrospectively identified healthy children aged 1–18 years between 2014 and 2020 with AH diagnosis from the Clalit Health Services database, the largest healthcare maintenance organization in Israel. The main outcome was adenoidectomy alone or in combination with other procedures performed within 2 years after diagnosis. The treatment group consisted of children who received medical therapy, defined as a pharmacy purchase of montelukast, nasal steroid sprays and/or antihistamines (medical therapy aimed to reduce AH) for ≥2 consecutive months, while the control group consisted of untreated children. Results: We identified 68,356 unique children with AH, of them 56 % were boys, with a mean age of 4.9 ± 3.3 years. Of them, 5310 (7.7 %) received medical therapy. Overall, 6633 (9.7 %) underwent adenoidectomy within 2 years following diagnosis. There was no significant difference in surgery referral rates between the treatment and the control groups, 10 % vs. 9.7 %, respectively (p = 0.3). When adjusted for age and sex, the likelihood of undergoing adenoidectomy was similar in both groups (HR = 0.98, 95 % CI = 0.90–1.07, p = 0.6). Among operated children, the average time from diagnosis to surgery was statistically significantly longer in the treatment group than in the control group, 346 ± 180 vs 311 ± 175 days (p < 0.001). Conclusion: Prescribing montelukast, nasal steroids and/or oral antihistamines was not associated with a reduction in adenoidectomy rates and was associated with an average surgery delay of 35 days.
