Abstract

Background: To assess cases of tympanic membrane perforation.
Materials and Methods: One hundred ten patients with dry perforations of tympanic membrane with no history of active middle ear disease were enrolled and the type, degree and frequency of hearing loss was determined by tuning fork test and pure tone audiometry. Clinical parameters such as cause of injury, side, site, complaints and type was recorded. The duration of disease was also recorded.
Results: Out of 110 patients, males were 65 (59.0%) and females were 45 (41%). Cause of perforation was RTA in 52, domestic assault in 38 and armed robbery in 20. Type was penetrating in 66 and non- penetrating in 44. The difference was significant (P< 0.05). Side involved was left in 46 and right side in 64. Site was anterior in 53, posterior in 41 and undefined in 16. Complaint was otalgia in 62, otorrhoea in 75, vertigo in 27 and tinnitus in 27. The difference was non- significant (P> 0.05). The mean hearing loss in 0-9 mm³ perforation was 24.1 dB, in 9-30 mm³was 36.7 dB and >30 mm³was 47.5 mm³. The difference was significant (P< 0.05).
Conclusion: Commoncause of perforation was RTA, domestic assault and armed robbery. Type was penetrating and non- penetrating. Complaint was otalgia, otorrhoea, vertigo and tinnitus.
