Abstract  Background:  The effect of tonsillectomy with adenoidectomy (T&A) on otitis media has been investigated, but there have been no reports of the relationship between T&A and medical services used in association with otitis media. We investigated the effect of T&A on otitis media with regard to the number and cost of medical services used. Methods:  From the National Health Insurance Service National Sample Cohort data in Korea, we selected patients 7 years old or younger in 2002 who had T&A in 2005 while between the ages of three and ten. A control group was established matching the patient group with similar propensities of demographic characteristics. The number and cost of medical services used in association with otitis media were analyzed for 3 years before T&A through 8 years after T&A. Results:  The total number of patients was 1,338, with 227 in the T&A group and 1,111 in the non-T&A group. The number of medical services used was not significantly different between the T&A and non-T&A groups before and after surgery. The cost of medical services used was significantly higher in the T&A group than in the non-T&A group one year before surgery. The cost of medical services used was not significantly different between the two groups after surgery. Conclusions:  There were no significant differences between the T&A and non-T&A groups in the number and cost of medical services used in association with otitis media after surgery. Keywords:  Tonsillectomy, Adenoidectomy, Otitis media, Medical service, Population-based study Background Tonsillectomy with adenoidectomy (T&A) is a commonly performed surgery for children in otorhinolaryngologic departments [1–5]. Frequent tonsillitis and obstructive sleep apnea are indications for T&A [3–5].

Otitis media is also a common disease in children [6]. Studies that have explored the effect of tonsillectomy or adenoidectomy on otitis media have specifically investigated disease occurrence, the disease-free period, and the rate of ventilation tube insertion [1, 3, 7–10]. Although several studies have reported reductions in health care costs or visits in association with obstructive sleep apnea syndrome or in general after T&A [11, 12], there have been no reports of the relationship between
