Our Experience in Endoscopic Button Tympanoplasty Providing High Success Rate in Varying Sizes of Perforation : A Case Series.

Abstract

Cartilage tympanoplasty is a fast growing technique used to restore hearing in chronic suppurative otitis media. The technique has misnomers such as limited applicability in only small size perforations, interference with sound conducting mechanism and durability. Our experience in out tertiary care Institution with over 100 retrospective study cases prove that there is a scope of proving it to be well established technique. That could be used in par with other tympanoplasty techniques. Our retrospective case series of 100 operated between 2021 and 2024 were taken, having unilateral perforation convenience data collection purpose. The overall success rates of cartilage / button tympanoplasty of varying perforation sizes, having a wide range of pure tone audiometry statuses having successful results were discussed, which is indicated as a percentage format. In our retrospective case series, out of our 100 cases we had 90 successful graft uptake cases. The 10% cases were later followed up in our study. It was analysed and concluded that the technique was not the inhibiting factor but the post operative care had prevented the patients from having the desired results. Our results are in accordance with previous case studies for support. Pure tone audiometry were taken pre operatively and post operatively that support cartilage / button tympanoplasty. Cartilage tympanoplasty is a commonly misunderstood technique which if corrected has a wide scope to be used a s a common treatment modality. Data collected and inference were in concordance with previous studies conducted. Tragal cartilage due to its durability, low inflammatory reaction to tympanic membrane, lesser chances of retraction and long term assurance of withstanding environmental conditions has proven to be technique which can be used in regular basis. Cartilage / button tympanoplasty is a technique that has a shorter learning curve for surgeons. With a high demand of cases in chronic suppurative otitis media-Tubotympanic type, button tympanoplasty technique is an assest.
