Endoscopic Myringoplasty for Pediatric Tympanic Membrane Perforations: Is It Worth It?

Background/Objectives: The endoscopic repair of the tympanic membrane is an established method for addressing perforations in the tympanic membrane. However, there are limited studies in the literature examining the success rate of this procedure in the pediatric population. Methods: This study retrospectively analyzed data from the tertiary referral center at the University Hospital of Verona, Italy. This medical record contains data from 84 type 1 transcanal endoscopic tympanoplasties performed in pediatric patients between November 2014 and February 2022. Seventy-seven pediatric patients aged 4 to 16 years who underwent type 1 transcanal endoscopic tympanoplasty (seven of whom underwent bilateral surgery at different time points) were included in the study. Our study did not include more extensive procedures than type 1 endoscopic tympanoplasty. Only patients with tympanic membrane perforation due to simple chronic otitis media, trauma or when no apparent cause was found were included. Chronic otitis with cholesteatoma and other pathologies of the external or middle ear were exclusion criteria. Patients with a follow-up of less than 12 months were excluded from this study. The technique was based on the endoscopic placement of an underlay graft of temporal fascia or tragal cartilage to repair a tympanic membrane perforation. Demographic, clinical, audiologic, and surgical data were collected from each patient. In the study, we considered the reduction of the air-bone gap (ABG) as a functional outcome and the integrity of the reconstruction as an anatomic outcome of success. Results: The primary surgery had a closure rate of 92.9% (78 of 84). All patients underwent audiological evaluation 4-6 months post-surgery, with 84 ears tested. The mean preoperative ABG was 17.13 dB HL, reduced to 9.16 dB HL postoperatively, showing a mean reduction of 7.97 dB HL. No significant complications occurred. Conclusions: Transcanal endoscopic type 1 tympanoplasty should be considered a safe procedure with a high success rate for the repair of tympanic membrane perforations, even in pediatric patients.
