High age at the time of implant installation is correlated with increased loss of osseointegrated implants in the temporal bone.

Background: The implant failure rate in temporal bone has been reported to be about 5 to 10% over a 10-year period. A number of our elderly patients have shown increased failure rates over a long time period, which is the reason for the present study.

Purpose: The aim of the present study was to find out if age is correlated with implant failure and to measure blood flow in implant sites.

Facial palsy and Wegener's granulomatosis.

Facial palsy can occur as a result of various pathological processes, which are not always amenable to early diagnosis. This article is a case presentation of a patient with facial palsy, after an acute otitis media manifestation, as a first symptom of Wegener's granulomatosis. The clues leading to diagnosis consist of the practitioner's clinical suspicion of the disease, the use of the appropriate serological measurements (c-antineutrophil cytoplasmic autoantibody), and the histological confirmation.
