Tympanoplasty with or without mastoidectomy: A comparative study for the treatment of chronic suppurative otitis media tubotympanic type

Abstract

Background: A chronic infection confined to the middle ear mucosal cleft that comprises the eustachian tube, mesotympanum, aditus, and mastoid air cells is defined as chronic otitis media (COM). Materials and Methods: 80 patients with chronic suppurative otitis media of both genders were divided into two groups of 40 each. Group I patients underwent tympanoplasty, and group II patients underwent tympanoplasty with cortical mastoidectomy. Results: Group I had 18 males and 22 females and Group II had 17 males and 23 females. Age group 14-30 years had 25 patients in group I and 22 in group II, 31-50 years had 10 patients in group I and 12 in group II and > 50 years had 5 in group I and 6 patients in group II. The difference was non- significant (P= 0.793). Graft acceptance rate was seen in 40 patients in group I and 7 patients in group II. Graft rejection rate was 44 patients in group I and 3 patients in group II respectively. The difference was highly significant (P< 0.001). Hence in our study we have found that there was no significant difference in the graft uptake rates between the two groups. 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.
