Abstract: | Two hundred twenty cases of unilateral chronic suppurative otitis media (CSOM) with dry central perforation were chosen for
this study and myringoplasty were done. Age group ranged from 13 to 48 years. Four types of autogenous tissues were used as
graft material. Grafting was done by underlay technique when temporalis fascia, tragal perichondrium, areolar tissue were
used as graft material and when fat graft was used the ear lobule fat was placed directly into perforation through transcanal
route. Postoperative follow-up was carried out up to 6 months. In this study, it was found that the younger age group has
less impairment of hearing and better chance of tympanic membrane perforation closure than the older age group in CSOM with
central perforation. Anterior perforations has less impairment of hearing and better result in successful closure of tympanic
membrane than posterior perforation group. It was also observed that larger the size of perforation greater is the hearing
impairment preoperatively and postoperative hearing gain is also less compared to small perforation. Best hearing improvement
occurred using temporalis fascia. Failure occurred may be due to postoperative infection, respiratory tract infection, neglected
post-operative advice etc. |
