Background: Chronic otitis media (COM) is a persistent inflammation of the middle ear, often characterised by repeated infections and ear discharge. The present study was conducted to compare tympanoplasty and tympanomastoidectomy for the surgical outcome in tubotympanic type CSOM. Materials and Methods: 94 patients with chronic suppurative otitis media of both genders were divided into two groups of 47 each. Group I patients underwent tympanoplasty, and group II patients underwent tympanoplasty with cortical mastoidectomy. Results: Group I had 20 males and 27 females, and Group II had 22 males and 25 females. Age group 20–40 years had 35 patients in group I and 30 in group II; 40–60 years had 12 patients in group I and 14 in group II; and >60 years had 2 patients in group I and 3 patients in group II. The difference was non-significant (P > 0.05). Graft acceptance was seen in 40 patients and graft rejection in 44 patients in group I and 7 patients and 3 patients in group II, respectively. The difference was significant (P < 0.05). Conclusion: When treating CSOM tubotympanic type with dry ear, cortical mastoidectomy does not provide a statistically significant advantage over simple tympanoplasty in terms of graft acceptance rate and disease elimination.
