Outcome of malleo-stapedotomy using the malleus relocation technique during revision stapes surgery.
OBJECTIVE
This study aimed to use a new otological technique, malleus relocation, to solve the problems of ossicular reconstruction undertaken during revision stapes surgery for incus necrosis.


METHODS
Prospective study of 12 patients undergoing revision stapedectomy for incus necrosis, in the otolaryngology department of Mansoura University, Egypt.


METHODS
Twelve patients underwent ossiculoplasty between June 2004 and June 2007, as part of revision surgery for otosclerosis with incus necrosis. All patients underwent ossiculoplasty using the malleus relocation technique. Ossiculoplasty used the patient's own, necrosed incus between the relocated malleus and the footplate.


RESULTS
Post-operative air-bone gap closure to within 10 dB was achieved in seven patients (58.3 per cent). An air-bone gap of less than 20 dB was obtained in 10 patients (83.3 per cent). Deterioration of bone conduction by 10 dB occurred in one case. No patients were left with a 'dead ear'. Patients' hearing was stable throughout the follow-up period (range six to 40 months; mean ± standard deviation 23.5 ± 12.8 months).


CONCLUSIONS
These findings indicate that malleus relocation, performed during revision stapes surgery, is a safe and efficient technique for the treatment of incus necrosis.
