Adenotonsillectomy is the most commonly performed surgery in children. To evaluate the effects of pediatric adenotonsillectomy on health care utilization. From 2006 to 2017, age/sex-matched adenotonsillectomy participants (n = 243.396) and controls (n = 730.188) were selected (62% of male and 38% of female. 47% age≦ 6, 16% 7–9years, 8% 10–12years, 29% 13–18years). The changes in outpatient visits, hospitalization days, and drug prescriptions due to a URI, asthma, and rhinitis before and after the surgery date (from 13 months to 1 month) were compared. Outpatient visits decreased more in the surgery group than the control group (mean change, 3.24 ± 8.61 d and 1.16 ± 6.57 d for URI, 2.07 ± 8.63 d and 0.51 ± 6.47 d for rhinitis, and 0.72 ± 4.81 d and 0.42 ± 3.91 d for asthma, p <.001 for all). Hospitalizations also showed greater decreases in the surgery group (mean change, 0.31 ± 2.96 d and 0.04 ± 1.70 d for URI, 0.13 ± 2.40 d and 0.02 ± 1.48 d for rhinitis, 0.11 ± 2.32 d and 0.04 ± 1.83 d for asthma, p <.001 for all). The prescription of antihistamines, leukotriene modulators, oral antibiotics, oral steroids, and expectorants, cough suppressants and oral bronchodilators was also decreased after surgery. The adenotonsillectomy group showed a greater decrease in post-operative outpatients visits, hospital days and drug prescriptions associated with URI, rhinitis and asthma than the control group.

Objectives: This study aimed to compare the characteristics of idiopathic unilateral vocal fold paralysis (IUVFP) in elderly versus younger patients, including the diagnostic yield of computed tomography (CT) scans for identifying the structural causes of IUVFP. Methods: We retrospectively analyzed medical records of the patients initially diagnosed with IUVFP in a single referral tertiary hospital. We compared patients’ baseline characteristics, initial symptoms, laryngoscopic findings, and prevalence of structural causes on CT scans with respect to age (younger, <65 years vs older, ⩾65 years). Results: One hundred forty-two patients were enrolled (90 younger, 52 older). Evident structural causes were more frequently found on CT in older patients than younger patients (40.4% vs 22.2%, P = .034). Among truly idiopathic cases (70 younger, 31 older), recovered vocal fold mobility was identified in 48.6% younger and 41.9% older patients (P = .666). There was no statistically significant difference in the characteristics between unrecovered and recovered subjects of the older patients with true IUVFP (all P > .05). Conclusions: The CT scans provided significantly higher diagnostic yields in older patients than younger patients. The degrees of symptoms and complications and likelihood of natural recovery did not significantly differ between younger and older patients with IUVFP. [ABSTRACT FROM AUTHOR]
