Abstract

Primary objective of this study was to compare the role of canalplasty in tympanoplasty, with that of only tympanoplasty, in patients of chronic suppurative otitis media with narrow external auditory canal and moderate to large central perforation, in terms of hearing improvement, graft uptake, intra operative ease. This study included 60 patients with chronic mucosal otitis media with narrow external auditory canal, with moderate to large central perforation, presenting to our institution from September 2019 to August 2021. Group A consisted of 30 patients, who underwent tympanoplasty with canalplasty and Group B consisted of 30 patients, who underwent tympanoplasty without canalplasty. Both the groups were followed up for 3 months, compared and analysed for hearing improvement and graft uptake. The results of our study indicated that Group A achieved 93.3% graft uptake rates compared to group B which achieved 80%. In Group A gain in air bone gap was 12.43 dB, whereas in Group B it was about 9.50 dB. Group A had significant hearing improvement and better graft uptake compared to Group B. It is advantageous to perform canalplasty prior to tympanoplasty in patients with narrow external auditory canal in whom the entire rim of annulus is not visible in one microscopic view. It yields better hearing improvement and graft uptake and prevents lateralization of the graft.
