Introduction :
Tympanoplasty is a commonly performed surgical procedure aimed at repairing perforations of the tympanic membrane, primarily to restore hearing and prevent recurrent infections. Over the years, various modifications to the technique have been introduced to improve outcomes, particularly for patients with central perforations. This study examines the outcomes of a modified tympanoplasty technique in a cohort of 375 patients.
Methods :
This retrospective case series evaluated the outcomes of a modified tympanoplasty technique in 375 patients (ages 10?60) with central perforations. The study was conducted from January 2010 to July 2016 at the National Institute of ENT, Tejgaon, Dhaka, Shaheed Suhrawardy Medical College Hospital, Dhaka, and various private hospitals equipped with micro ear surgery facilities.
Preoperative and postoperative audiological testing, clinical examinations, and radiological assessments were performed. Data analysis was carried out using SPSS with descriptive statistics to summarize demographics and surgical outcomes.
Results :
In this study of 375 patients undergoing modified tympanoplasty, the largest group was aged 21?30 years (29.33%). A high success rate of tympanic membrane closure was observed, with 96% achieving closure.
Most patients (73.6%) underwent tympanoplasty alone, while 26.4% had additional cortical mastoidectomy. The majority experienced mild hearing improvement (75% with 10 dB gain).
Complications included otomycosis (69.7%) and graft failure (15.15%).
Conclusion :
The inlay technique produces early healing of tympanic membrane perforation and is effective in both adults and children. The modification reduced operative time and provided minimal scarring for all types of perforation in tubotympanic or mucosal-type chronic otitis media, making it suitable as a routine procedure in day-to-day practice.
