Tympanoplasty is a surgery done to repair a perforation (hole) in the eardrum. A perforation in the eardrum can result in recurrent ear infections. Thus, the aim of the tympanoplasty is to prevent the recurrent infection. It often helps to improve your hearing as well.
This surgery is done under general anaesthesia. The repair is done by means of a graft placed to cover the perforation. The graft may either be harvested from your own fascia or made of a synthetic material.
