Cartilage tympanoplasty.

This chapter describes two techniques for cartilage reconstruction of the tympanic membrane: the perichondrium/cartilage island flap, which uses tragal cartilage, and the palisade technique, which uses cartilage from the tragus or cymba. The perichondrium/cartilage island flap is preferred for management of the atelectatic ear and the high-risk perforation. The palisade technique is preferred in cases of cholesteatoma and when ossicular reconstruction is needed in the malleus-present situation. Descriptions of the modifications that should be taken in response to specific surgical indications are also provided and include the high-risk perforation, the ear requiring ossiculoplasty, the atelectatic ear, cholesteatoma, and pervasive Eustachian tube dysfunction.

[Tympanoplasty using cartilage: 3 years of experience].

We present our results in a timpanoplasty technique using autologous cartilage, in a retrospective study of 71 cases within 3 years. We used this technique in revision surgery, large perforations, severe retractions, and atrophic membranes. 32% of cases needed ossicular chain reconstruction. A complete closing of the membrane was obtained in 86% of cases, while 14% remained re-perforated or discontinued between cartilage pieces. These results are comparable to other studies using cartilage graft with several techniques. These results encourage us to continue using this technique in order to acquire more experience and a better knowledge about the efficacy of this technique.

Cartilage perichondrium composite graft (CPCG) in pediatric tympanoplasty.

Different policies on the treatment of tympanic membrane perforation in the pediatric age group continue to exist. Thirty patients were included in this study over a period of 2 years, where cartilage perichondrium composite graft (CPCG) was used to close the tympanic membrane perforation. Successful drum closure was achieved in 86.6% of cases, regardless of the site of perforation or the status of the operated ear. The graft was taken from the tragus and was placed in an underlay fashion with cartilage towards the promontory and the perichondrium immediately to the tympanic membrane remnants. The postoperative hearing gain although delayed up to 6 months was excellent either subjective or objective. So, CPCG has proved advantageous as a graft material to close perforation in the tympanic membrane in pediatric age group.

Tympanoplasty and recurrent disease: sniff-induced high negative pressure in the middle ear space.

Eustachian tube function was studied in 18 patients who had developed recurrent middle ear disease after middle ear surgery on one ear. The types of recurrent disease included recurrent retraction of the tympanic membrane, recurrent cholesteatoma, columella penetration, postoperative perforation, and infection. Pressures in both of the middle ears, as well as in the nasopharynx, were recorded simultaneously. The ears of patients in this study were found to be able to equalize pressure as well as did normal ears examined previously. However, in 12 of the 18 ears that had been operated on, failure of eustachian tube closing with sniff-induced negative pressure in the middle ear was found. Additionally, in three patients, a similar condition was present in the contralateral ear. It is concluded that postoperative complications of the types described may be correlated with tubal closing failure and sniff-induced high negative pressure in the middle ear space.

Tympanoplasty with reconstruction of soft posterior meatal wall in ears with cholesteatoma.

A surgical technique for the reconstruction of a posterior meatal wall using a soft material (fascia) was developed for ears with cholesteatoma. Both myringoplasty and reconstruction of the posterior meatal wall were simultaneously performed using a large sheet of fascia, after the removal of the posterior meatal bony wall and the lesion. Even if postoperative middle ear aeration is disturbed, a retraction pocket may be expected to occur easily in ears with a soft posterior meatal wall, because of its flexibility compared to ears with a usual hard posterior meatal wall. This method is simple and can be useful in ears in which the posterior bony wall is removed.

Incidence of attic retraction after staged intact canal wall tympanoplasty for middle ear cholesteatoma.

Incidence of retraction pocket and recurrent cholesteatoma in the attic after surgery for middle ear cholesteatoma using the staged intact canal wall technique were investigated in 95 ears of 91 patients, all of which had various degrees of bone defect in the tympanic scutum. Surgical procedures employed in the second stage for prevention of attic retraction were classified into three types: Type I, no scutumplasty; Type II, scutumplasty; Type III, scutumplasty plus mastoid obliteration. In 83 ears followed up for more than 1 year after the second stage, such retraction troubles occurred in 2 of 13 ears (15%) in Type I, 8 of 20 ears (40%) in Type II, and 24 of 50 ears (48%) in Type III. Incidence of retraction troubles was higher in Types II and III, probably because these procedures were indicated in ears with large scutum defects. Dislocation and atrophy of the graft materials, together with bone resorption around the bone defect were the main reasons for failure in scutumplasty. Dysfunction of the eustachian tube and traction of the eardrum by the scar tissue behind it may have also contributed to attic retraction. Mastoid obliteration with small blocks of hydroxyapatite was more effective in prevention of retraction troubles than that with pedicled temporalis muscle flap.
