Abstract :

Background and objectives: Tympanoplasty is the most common surgical procedure performed for middle ear pathology. It is done to clear the disease from the middle ear cleft, to close the perforation of tympanic memane and to improve the heå. Canalplasty is done to widen the bony external auditory canal as a part of Tympanoplasty. This study was conducted to compare the heå improvement following Tympanoplasty alone and Tympanoplasty along with Canalplasty. MATERIALS AND METHODS: This is a comparative, retrospective, longitudinal and double blind study with 200 patients. All are having chronic suppurative otitis media(CSOM), inactive, mucosal type with central perforation. All the patients were divided into 2 groups, 100 patients in each group. Preoperative and postoperative assessment done both clinically and audiologically. All patients underwent surgery under general or local anaesthesia, postauricular approach, temporalis fascia graft and underlay technique. Group 1 patients underwent Tympanoplasty alone and group 2 patients underwent Tympanoplasty along with Canalplasty. RESULTS: Heå improvement in two groups was assessed by clinical and audiological examination, pre and post operative audiograms compared. Average heå improvement in group 1 is 16.3db and Average heå improvement in group 2 is 21.9db. CONCLUSION: Analysis of results revealed that Tympanoplasty along with Canalplasty is more beneficial to the patient as it resulted in more heå improvement than Tympanoplasty alone.
