Abstract
The surgical approaches to repairing tympanic membrane perforations and control of middle ear disease have been well documented in the literature. One is the transcanal approach. The experience with this approach in controlling middle ear disease in 242 cases using both homologous dura and autologous temporalis fascia will be discussed. The results of graft taking and closure of air-bone gap to within 10 dB were slightly better using temporalis fascia compared with dura graft (86.7%) and (78.1%), respectively. Complications in the form of graft failure and high frequency sensory neural hearing loss (S.N.H.L.) were found to be greater in revision cases and in cases using dura. Most of our patients had wide external auditory canals, making this approach easy. Post-operative recovery is quick and morbidity is of short duration with no cosmetic derangements. This is important, as the cost-effectiveness is increased by reducing the time in the hospital and allowing more cases to be operated.
