Allograft tympanoplasty.

Tympano-ossicular allografts are human transplants of the tympanic membrane alone or with the ossicles included. The authors review its use in their department since the introduction of the technique 40 years ago by J. Marquet. The advantages of the technique (near normal anatomical and physiological reconstruction) are discussed, as well as its disadvantages (time consuming harvesting, risk of disease transmission). Some technical modifications for specific indications have been adapted in our department and are described in detail. The authors believe that the tympano-ossicular allograft is the material of choice in extensively diseased middle ears destroyed by chronic otitis media with or without cholesteatoma.

[Tympanoplasty decision making in a child with HIV contamination--case report].

Otologic problems are infrequent in HIV patients. Authors present the case of chronic otitis media in the HIV infected child. The patient with significant hearing loss, and prolonged aural discharge, resistant to local and systemic antibiotic treatment was treated surgically. Mastoidectomy with myringoplasty was performed. The substantial hearing improvement has been obtained, ear discharge never returned. However due to episodes of chronic otitis media with effusion ear drainage with tympanostomy tubes, after initial surgery have been performed two times. The controversies regarding surgery decision-making in this group of patients are discussed.

[Circumferential subannular grafting technique in tympanoplasty: preliminary results].

OBJECTIVES: We evaluated the preliminary results of the circumferential subannular grafting technique, which has been proposed as a modification of the standard underlay method. PATIENTS AND METHODS: Twenty patients (15 females, 5 males; mean age 32.4 years; range 13 to 65 years) with chronic otitis media were operated on with the use of the circumferential subannular grafting technique. The mean follow-up was 13.6 months (range 1 to 36). RESULTS: No complications were encountered related to graft survival or the external ear canal. The mean air-bone gap was 25.2+/-8.6 dB preoperatively and 15.8+/-7.4 dB postoperatively, with a mean decrease of 10+/-7.9 dB. CONCLUSION: Circumferential subannular grafting was found to be effective in restoring tympanic membrane perforations in all the quadrands. The main limitations of the technique are the need for surgical skills and the necessity of an intact or remnant manubrium mallei.

Tympanoplasty type-1. Endaural or postaural approach. Should the patient decide?

OBJECTIVE: To examine the preferred patient approach to chronic suppurative otitis media (CSOM) of the safe type. METHODS: We designed a prospective study to note the variables in the patient's initial choice for approach to CSOM of the safe type at Buraidah Central Hospital, Al-Qassim, Saudi Arabia from January 2003 to December 2004. RESULTS: During the 24-month study period, we included 63 consecutive patients diagnosed with CSOM of the safe type. We excluded patients with perforations associated with cholesteatomata, polyps, and acute infections. We administered a questionnaire discussing the options for the operation, and found most males preferred the endaural approach, and most females preferred the postaural approach. CONCLUSION: There was a significant preference by younger age groups for the postaural approach, especially younger females. They were more concerned about the site, visibility, and cosmetic result from the scar, and could camouflage the scar behind the pinna by hair or a traditional headscarf.

[Value of collagen type IV in tympanoplasties. Animal experimentation in rats].

The authors recall the importance of collagen in the ultrastructure of the lamina propria and the properties of the type IV collagen concerning epidermic healing. Tympanomeatic graft composed of reticulated type IV collagen was used as a graft in rats. This experimental study demonstrated a good stability of the graft 40 days after operating. A new non toxic cross linking technique has been developed to stabilise of the biomaterial. The type IV collagen film shows good properties for the growth and the differentiation of epithelial cell like keratinocytes.

Tympano-ossicular allograft tympanoplasty. Physiocompatibility.

The aim of the work is to point out some physiological aspects of the tympano-ossicular allograft as well of its receptor site. The typical fibrous weft of the membrane which closely sticks to the handle of the malleus, on one side, and in the sulcus, on the other side, gives an optimal layout and ensures the stability of the graft. The presence and flexibility of the joints enable the ossicular chain of the allograft to provide protection for the inner ear.

Eustachian tube function and tympanoplasty.

104 ears with preoperative poor Eustachian tube (ET) function were analyzed 1-2 years after surgery in order to find out whether or not the ET function improves as a result of the surgical procedure. The majority of ears with poor preoperative ET function (77%) continue to have poor ET function after surgery as judged by tympanometry and ET function testings.

[Fibrin glue in tympanoplasty].

In order to achieve more favourable anatomic and functionally more permanent position of the transmission materials, fibrin glue was applied in 68 patients undergoing different microsurgical interventions for the cure of inflammatory processes in the middle ear or improvement of conductive deafness of inflammatory or traumatic origin. Fibrin glue has shown to be equally suitable both in fixation of the biological materials - homografts and autografts and in fixation of alloplastic prostheses. The efficacy of preservation of the best position was demonstrated in all forms of direct collumelas, ossicular graft interposition, closure of the labyrinthine fistulas and reconstruction of the external attic wall.
