  • Look Inside

 A new surgical technique of tympanoplasty is presented for the treatment of continuously discharging ear with postoperatively opened mastoid cavity. This technique aims at the reconstruction of the middle ear cleft after complete eradication of the affected parts. The prime goal is to have a dry ear, free from infection. The tympanic cavity is restored by a newly created tympanic membrane of lamellar cartilage and perichondrium. In case of absence of the superstructure of the stapes, the sound vibrations are transmitted from this new ear drum by an autogenous cartilage strut to the footplate. Fascioperiosteal pedicle flap with lower hinge is used to create the new posterior canal wall. Old mastoid cavity exposed to the ear canal and external environment is closed, but aerated from the tympanic cavity through the attic.

 In twelve cases for whom this technique has been used, dry ears were obtained with conditions close to the normal contour. Hearing was not much improved three months after the surgery.
