Tympanoplasty: TORPS and PORPS.

We reviewed 106 cases in which PlastiPoreTM prostheses were used for ossicular reconstruction. In all cases a piece of cartilage was interposed between the prosthesis and the tympanic membrane graft to prevent the potential problem of prosthesis extrusion. With total ossicular replacement prostheses (TORPs) 55% closed to within 10 db and 85% closed to within 20 db of the bone conduction level. Closure to within 10 db of the bone conduction level was accomplished in 64% of partial ossicular replacement prostheses (PORPs) cases. These results are better than obtained previously with either ossicles or cartilage alone.

A decade of tympanoplasty: progress or regress?

The surgery of chronic ear disease has continued to be a popular topic during the seventies. The literature for this period has been collected and organized by both surgical topics and disease topics. The changes in technique, particularly for ossiculoplasty, are discussed in the light of the author's experiences. The surgical approaches to a particular disease process are likewise reviewed. Changes in surgical philosophy are discussed both for particular authors as well as for the overall trends.

Solving ossicular problems in tympanoplasty.

Four troublesome problems encountered in ossicular reconstruction are: low profile stapes, lateral tympanic membrane, remaining stapes crura, and absent stapes capitulum. The design advantages and modifications of the semibiological ossicle cup and ossicle columella prostheses are given to solve these problems. The hearing results are completely satisfactory.

Comparative study in tympanoplasties with nitrous oxide anesthesia.

A number of intra and postoperative accidents in close cavity surgery when using nitrous oxide have been reported. In order to check the influence of nitrous oxide anesthesia in tympanic surgery, 38 patients were operated on by the usual techniques in middle ear surgery. Half the patients received continuous nitrous oxide inhalation throughout the procedure while, in the remaining cases, the anesthetic gas was suspended 30 minutes before applying the tympanic graft. Audiological differences in both groups, as controlled at 6 and 12 months, were negligible.

Reconstruction of the Eustachian tube and the anterior tympanum: planned staged tubo-tympanoplasty.

A new technique is demonstrated in the management of chronic otitis media with inflammatory stenosis of the Eustachian tube. Bone exposure of the Eustachian tubal orifice and peritubal air cells was followed by placement of a long T-shaped solid silicone plate in this area. Postoperative care was taken to ensure wound healing in the same way as after radical mastoidectomy. At the second stage surgery the Eustachian tube and pretympanum were found to have developed with an intact mucous membrane. A middle ear space with or without reconstruction of the posterior meatal wall and obliteration of mastoidectomy cavity could easily be rebuilt. A sound pressure transformer mechanism could be established at the second stage surgery.

A review of 925 cases of tympanoplasty using formaldehyde-formed-fascia grafts.

In this review of 925 cases of total and anterior perforations of the tympanic membrane reconstructed through the use of formaldehyde-formed-fascia (3-F) grafts, the postoperative nonperforation rate is 97.6%; blunting and/or lateralization of the graft was avoided in 93.5% of cases. Closure of the postoperative air-bone gap within 20 dB was achieved in 70% of cases. This update of a previously reported paper reinforces our opinion that the 3-F graft is an effective tool for the closure of tympanic membrane perforation with or without ossicular chain reconstruction.

Intact canal wall tympanoplasty with mastoidectomy for cholesteatoma: long-term follow-up.

One hundred four ears operated for cholesteatoma using the intact wall technique were studied in 1981. In the 1981 study, there was a 7% recurrence rate in adults and a 25% recurrence rate in children after a 5-year follow-up. Recognizing that chronic otitis media is often not controlled by surgery, long-term follow-up is necessary to evaluate a particular operative approach to control the disease and restore function. The purpose of this study is to reexamine the series of patients studied in 1981 and evaluate the status of the ear, as well as long-term functional results.

Cartilage tympanoplasty for management of retraction pockets and cholesteatomas.

Retraction pockets of the tympanic membrane, often associated with dysfunction of the eustachian tube, can be destructive, leading to loss of hearing, ossicular erosion, and development of cholesteatomas. This retrospective study reviews results from 35 patients (38 ears) operated on from January 1988 to June 1991 whose composite cartilage-perichondrial grafts harvested from the tragus were used to reconstruct the tympanic membrane. Early grafts reinforcing the posterosuperior quadrant of the pars tensa showed some failures, with recurrent retraction in the attic. In later grafts, additional placing of cartilage under the pars flaccida prevented failures in the attic. Our indications, initial technique and refinements to the present form, and hearing results are discussed.
