title: Posterior canal wall reconstruction tympanoplasty for operated ears with open mastoid.
abstract: We investigated the postoperative conditions of ears and the hearing acuity of patients who underwent posterior canal wall reconstruction tympanoplasty for operated ears with open mastoid. The study included 118 ears of 105 patients (57 males, 48 females; age range 5-75 years) and the patients were followed for > 1 year after the final operation. Although 114 ears (97%) were dry after the final operation, retraction pockets and eardrums in a lateral position were observed in 5 ears and in 1 ear, respectively. Ossicular reconstruction was performed in 83 ears and in these the mean air conduction hearing levels were significantly improved after the final operation in those that were subjected to type III and IV tympanoplasty. These results indicate that posterior canal wall reconstruction tympanoplasty can be considered to be an effective procedure.
