    Abstract:
    OBJECTIVE: The purpose of this study was to evaluate the functional duration and survival rate of tympanostomy ventilation tubes and the complications associated with their use in pediatric patients who underwent tube insertion for otitis media with effusion (OME). Complications were analyzed including recurrence and tympanic membrane perforation after the tube removal or extrusion. METHODS: Altogether, 447 ears from 234 pediatric patients younger than 15 years of age were studied retrospectively. All patients had undergone long-term tympanostomy ventilation tube: the Goode T-tube insertion for OME at the Osaka Women's and Children's Hospital, which is the pediatrics specialty hospital between April 2014 and March 2016. They were typically followed up every 3-4 months or more frequently if necessary due to otorrhea or tube infection. Subsequently, the tube duration, survival rates of the tube especially at 22 months after insertion defined as "full-term placement", and the rates of recurrence and perforation were calculated and statistically evaluated. RESULTS: Of 447 ears, 335 ears from 184 patients underwent their first tube insertion, and 112 ears from 64 patients underwent their second or subsequent tube insertion within the targeted period. Two hundred ears from 106 patients were associated with a cleft palate. The survival rate at full-term placement was 51.7%. The recurrence rate was 56.3%, and the rate of the tympanic perforation was 8.5%. CONCLUSIONS: Approximately half of the tubes survived for 22 months. The perforation rate was relatively low; however, recurrence of OME was seen in more than half the ears.
