Background:The present study was conducted to compare tympanoplasty with or without mastoidectomy in treatment of chronic suppurative otitis media tubotympanic type.Materials & Methods: The present study was conducted on 82 patients of chronic suppurative otitis media tubotympanic type of both genders. Patients were randomly divided into 2 groups of 41 each. Group I patients underwent tympanoplasty alone and group II patients underwent cortical mastoidectomy with tympanoplasty. Results: Duration of ear discharge was 4-6 years in 23 in group I and 27 in group II, 7-10 years in 12 in group I and 10 in group II and >10 years in 6 in group I and 4 in group II. Degree of hearing loss was mild in 34 in group I and 36 in group II and moderate in 7 in group I and 5 in group II. Size of perforation was medium in 4 in group I and 9 in group II, large in 26 in group I and 22 in group II and subtotal in 11 in group I and 10 in group II. The difference was significant (P< 0.05). The mean audiological assessment before was 38.12, after was 28.46 and benefit was 9.66 in group I and 38.24, 26.4 and 11.84 respectively in group II. The difference was significant (P< 0.05).Conclusion:Authors found that both the methods of treating cases of chronic suppurative otitis media tubotympanic type were equally effective
