Malleus-stapes assembly: experience with two prostheses.

Tympanoplasty is often a necessary part of middle-ear surgery, the most common defect being that between an intact, mobile stapes and the malleus handle. The most readily available tissue is the patient's incus, reshaped to bridge the space between an intact stapes and the malleus. When the incus cannot be used, the hydroxyapatite Wehrs incus prosthesis can be used as an alternative.Twenty-six patients had an autograft incus ossiculoplasty and 20 patients underwent modified Wehrs incus prosthesis ossiculoplasty. The average post-operative air-bone gaps (ABGs) were 16.2 dB hearing loss (dBHL) and 17.2 dBHL, respectively. Air-bone gap closure to within 15 dBHL was achieved for 48 per cent of incus autografts and for 57 per cent of Wehrs prostheses, and to within 20 dBHL for 77 per cent and 62 per cent, respectively. Over four years follow up, the reconstruction was stable for each group, the ABGs being 17.7 dBHL and 17.1 dBHL, respectively.

How we do it: modified Wehrs incus ossiculoplasty.

Keypoints * Ossiculoplasty is commonly performed as part of tympanoplasty. Hydroxyapatite is a favoured material for ossicular protheses. * A modification to the Wehrs incus prosthesis is described. * Twenty-one procedures were performed on 20 patients and the results are reported. * On average there was a 4-5 dB closure of the air-bone gap (ABG), with patients having a hearing gain procedure averaging 11 dB closure. Air-bone gap closure to <or=20 dB was achieved between 78% (0.5, 1, 2 kHz average) and 60% (0.5, 1, 2, 4 kHz average) of patients and this was stable during long-term follow-up of the ABG. * Wehrs incus prosthesis ossiculoplasty provides a reliable result following ossiculoplasty when autograft incus is not available.

Risk indicators associated with tooth loss in Jordanian adults.

OBJECTIVES: The purpose of this study was to evaluate the risk indicators of tooth loss in Jordanian adults. METHODS: A sample of 509 Jordanian adults was randomly selected. The subjects were interviewed regarding demographics, social economic status, smoking habits, and oral hygiene practices and then clinically examined by a single examiner. Multiple regression analysis was performed to estimate the simultaneous impact of risk indicators on tooth loss. RESULTS: The subjects' mean age was 42.6 years with an average of 20.9 teeth remaining per person. The overall educational level of the subjects was low. More than 40% reported not brushing their teeth regularly and 56% had had no professional teeth cleaning during the last year. Monthly family income averaged JOD 231, and about a third of the subjects were smokers. The mean number of remaining teeth decreased significantly with age. Smokers, those who brushed irregularly, and those who had not had professional teeth cleaning in the last year had significantly fewer remaining teeth. Men also had significantly fewer remaining teeth. Education and income were also significantly associated with the number of remaining teeth. Age, income, brushing, prophylaxis, and gender collectively explain 75.1% of the variance in the number of remaining teeth. CONCLUSION: Modification of non-disease independent factors could reduce tooth loss and improve oral health in Jordanians.
