Hearing conservation or gain are important parameters of tympanoplastic surgery. The frequency of this surgical procedure and the difficulty in obtaining tissues due to the increased risk of H.I.V. transfer has made the use of synthetic products somewhat more acceptable in contrast with the use of organic substances (homograft ossicles, bone, cartilage and(More)
Tympanoplasty does not resolve problems such as tympanic reconstruction, pneumatic cavity and ossicular transmission mechanism. With the purpose to solve these problems, we used autografts of tragal cartilage with its perichondrial membrane. In just one surgical procedure, we built a transmission mechanism and a consistent new tympanic membrane. Results(More)

The choice of surgical techniques has gone through a great evolution during the last few years in our service. Closed techniques were formally used in 80 per 100 of our operations (1974-1979) and now this has dropped to 12.5 per 100 (1979-1983) motivated by the failures we obtained with the closed techniques. This is similar to the observations of other(More)
We have carried out a retrospective study of 110 ears in patients affected with otosclerosis who underwent revision of stapedectomy, from 1979 to 1991, because they did not achieve hearing improvement or still presented persistent dizziness after primary stapedectomy. In our series, the most common causes of surgical failure after the first surgery are:(More)
We perform a comparative study on the results obtained through three stapedectomy techniques. The hearing gain was evaluated in 107 ears with total footplate removal, Shea prosthesis and connective tissue graft, in 81 ears with particular footplate removal, the same prosthesis, and no tissue graft, and in 66 ears with stapedectomy. The differences between(More)
A retrospective study of 1035 stapedectomies was performed to assess the incidence of intraoperative complications between 1972-1990. We found 45.89% of complications. We divided this alterations in 6 groups: 1) hemorrhage (20.67%), 2) stapes, foot plate, oval window (8.40%), 3) alterations in the middle ear (6.85%), 4) alterations in the incus (3.76%), 5)(More)
