Objectives: The aim of this study was to assess the impact on implant survival, abutment skin reaction and patient satisfaction in patients implanted with a bone-anchored hearing aid (BAHA), following the introduction of a multidisciplinary team (MDT) in 1997.

Design and methods: Part prospective and retrospective analysis. Implant survival and cause of failures were recorded along with abutment skin reaction (graded as none, mild, moderate and severe, according to the amount of wound care required). Patient satisfaction and quality of life were assessed using a questionnaire enquiring about several aspects of the use and benefits of their BAHA.

Setting and participants: Eighty patients treated at the Bradford Royal Infirmary between 1991 and 2005. The unit is a recognized tertiary referral centre.

Results and conclusions: Twelve out of 80 implants failed, giving an overall failure rate of 15 per cent. Kaplan–Meier survival curves show a steady decrease in implant survival. The MDT had a positive effect on implant survival and adverse skin reactions, with a higher proportion of patients experiencing no reaction after its introduction. There was a 92.5 per cent response rate to the questionnaire. Overall patient satisfaction was high, both before and after the introduction of the MDT.

An improved understanding of the interactions at the nanoscale level between the bioceramics in medical implants and the hard or soft tissues in the human body could contribute significantly to the design of new-generation prostheses and postoperative patient management strategies.Overall, the benefits of advanced ceramic materials in biomedical applications have been universally accepted, specifically in terms of their strength, biocompatibility, hydrophilicity, and wear resistance in articulating joints.The continuous development of new-generation implants utilizing nanocoatings with novel nanosensors and devices is leading to better compatibility with human tissue and improved well-being and longevity for patients. This article gives a short overview of bioceramics and reexamines key issues of concern for processing and applying nanoceramics as biomaterials.

Over a four-year period 72 children with ear abnormalities have been referred for assessment by the extraoral osseointegrated implant team at The Queen Elizabeth Hospital, Birmingham. Thirty-two children have been judged suitable for rehabilitation. Twelve children have completed rehabilitation using bone-anchored hearing aids and/or auricular prostheses. Two fixtures (seven per cent of those loaded) have dislodged and required replacement. Audiological assessment of the bone-anchored hearing aid users shows only small improvements in their aided thresholds, compared to thresholds obtained with their previous aid. However all now have thresholds of 30 dB(A) or better and report a marked improvement in sound quality. When surveyed, hearing aid and prosthesis users report high levels of satisfaction with this form of rehabilitation. The technique adds a new dimension to the management of children with aural anomalies. The approach and results of a multidisciplinary programme are reported.
