Journal Title: IJAR-Indian Journal of Applied Research - Year 2017, Vol 7, Issue 1
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 membrane and to improve the hearing. Canalplasty is done to widen the bony external auditory canal as a part of Tympanoplasty. This study was conducted to compare the hearing 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 erforation. 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: Hearing improvement in two groups was assessed by clinical and audiological examination, pre and post operative audiograms compared. Average hearing improvement in group 1 is 16.3db and Average hearing 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 hearing improvement than Tympanoplasty alone.
