From a series of 2335 cases of ear surgery over a five-year period, the author reports on 550 cases where perichondrium cartilage from the tragus or concha was used as transplant material. Two different surgical techniques were employed. The postoperative gain in hearing and the overall incorporation rate are presented.
This article analyses the advantages of the autogenous cartilage from the tragus split into multiple parallel pieces for the closure of big tympanic perforations and for the reconstruction of the middle ear after treatment of ventilation diseases like tympanic retraction or atelectasis. The cartilage is more stable than any other material and gives a better protection against recurrent retraction process. Dispersion into fractioned pieces produces very good functional results, as has been shown in this study.
OBJECTIVE: Because of continued eustachian tube abnormalities, the presence of a cleft palate repair has been thought to be associated with poor outcomes after tympanoplastic surgery. However, little published data exist regarding the results of major otologic surgery in patients with cleft palate. The objective of this study was to review our results of otologic surgery in these patients and compare results with those of age- and procedure-matched controls. METHODS: Our otologic database was used to identify patients with a repaired cleft palate who underwent otologic surgery between March 1994 and December 1999. Two control patients were identified for each cleft palate patient. Results of hearing, graft take, and need for postoperative pressure-equalizing tubes were compared. RESULTS: No significant difference existed between patients with a repaired cleft palate and control patients with regard to postoperative air-bone gap (P = 0.6805), graft survival rate (P = 1.00), and need for postoperative intubation (P = 0.457). CONCLUSION: Results in patients with cleft palate appear to be similar to those in patients without cleft palate.

The history of otology is the history of the successful treatment of infections of the middle ear and the eardrum. Otologists have sought to restore hearing lost to infections of the eardrum since the 1600s. The development of instruments, techniques, and materials to treat infection is fascinating because of the serendipitous nature of the discoveries and the insight of the discoverers. This historical review describes the history of the treatment of infections of the ear and the development of modern techniques of ear surgery. Two contemporary methods of tympanic membrane repair are then described.
For closure of a nonmarginal tympanic membrane perforation, currently popular techniques utilize either an underlay or an onlay approach. However, both procedures require incising canal skin. A transcanal inlay procedure could provide theoretical advantages of ease, speed, and comfort. Specifically designed cartilage that could facilitate the transcanal approach similar to placement of a solid tube was employed and evaluated. A transcanal cartilage butterfly inlay technique was found to be efficient and effective to close a subgroup of small-to-medium-sized tympanic membrane perforations including cases in which the condition of the tympanic membrane was somewhat hostile. Postoperative patient comfort was an additional benefit.
