Epidemiology of common otologic surgical procedures in pediatric patients: A population-based birth cohort study. (December 2019) - Wang, Mao-Che
Abstract: Objective: It is generally recognized the most common pediatric otologic surgical procedure is ventilation tube insertion (VTI). Tympanoplasty and mastoidectomy are more frequently performed on adults. In this study we examined the incidence and age distribution of these procedures by use of a population-based birth cohort design, in order to provide an overall view of the role of these procedures in the pediatric population. Materials and methods: We used the national health insurance research database in Taiwan. We retrieved data on all patients born in the years 2000 and 2001, subsequently underwent VTI, tympanoplasty or mastoidectomy from 2000 to 2013. The incidence and age distribution of these procedures were analyzed. Results: The cumulative incidence of VTI, tympanoplasty, and mastoidectomy was 0.41%, 0.02% and 0.025%, respectively. VTI were more often performed on children 4 or 5 years of age. Tympanoplasties are frequently done on children older than 5, and 30.7% of them had earlier VTI. The time interval from VTI to tympanoplasty was 5.18 ± 2.27 years (mean ± SD). Mastoidectomies are more often performed on children from 2 to 9 years of age. Conclusions: VTI was the most frequent otologic surgery for the pediatric population, and was more often performed on children 4–5 years old. Also, tympanoplasty is more frequently performed on children older than 5, and a third of them had prior VTI. Overall, the time interval from VTI to tympanoplasty was 5.18 years. Furthermore, children with cleft palate and congenital metabolic disorder were more prone to otologic surgical procedures.
