Indian Perspectives on Graft Materials Used for Repair of Tympanic Membrane.

INTRODUCTION: Repair of Tympanic Membrane (TM) is one of the most common surgeries performed by the otologists. Literature reveals that Indian surgeons have contributed substantially in the research on techniques and graft materials used for the repair of tympanic membrane, though no review has been written so far highlighting their contributions.

AIM: To summarize and analyse the contributions of Indian authors who have used different graft materials for repair of TM and their studies listed in Medline search.

MATERIALS AND METHODS: A literature review was conducted using a Medline search using keywords of 'myringoplasty' and 'tympanoplasty' with 'India' on 30th June 2016. A total of 243 articles were found listed onwards from year 1998. Out of these 50 articles in which type 1 tympanoplasty or myringoplasty was performed using different graft materials were selected. The content of each abstract was studied in order to identify studies related to topic.

RESULTS: Authors have experimented with a variety of tissues as graft materials. Temporalis Fascia (TF) has been most widely used in 58.6% studies as graft material. The next popular graft is tragal perichondrium. The graft take up rates varied from 68.5% to 100%, while method of reporting of hearing gain in most studies was inconsistent amongst studies, though most studies have reported achievement of serviceable hearing of < 25 dB in most patients.

CONCLUSION: TF was the most prefered material due to anatomic proximity, light material and strength. It was followed in popularity by tragal perichondrium and tragal cartilage. All graft materials have given satisfactory hearing results.
