Comparative Study of Outcome of Type 1 Tympanoplasty in Dry and Wet Ear in Tertiary Care Hospital.

Abstract

Chronic suppurative otitis media is very common otological disease in general population. Persistent wet ear produces dilemma for ENT surgeons whether to go ahead with tympanoplasty or not. Present study compare outcome of type 1 tympanoplasty in both wet and dry ear. Present study is randomized, prospective, Interventional type of study carried in ENT department of tertiary care hospital over period of 18months. Total 62 cases fulfilling study criteria were included in the study, which were equally divided in dry and wet group. All cases underwent type 1 tympanoplasty. Temporalis fascia was used as graft material in all cases. Most of the patients in both dry and wet group belonged to the age group between 21 to 30 (40.32%). 26 (41.94%) were males and 36 (58.06%) were females. Male: Female ratio was 1:1.38. After 12weeks 27 (87.10%) cases of dry group and 20 (64.52%) cases of wet group had significant hearing improvement and in dry group 28 (90.32%) cases had intact graft while in wet group 23 (74.19%) cases had intact graft. According to the statistical analysis, in current study, there is no significant differences between the success rates of wet and dry ears, either in terms of graft uptake or the hearing improvement, thus it can be concluded that the presence of minimal ear discharge at the time of surgery does not affect the success rate of type 1 tympanoplasty.
