Abstract
This report provides the first shortterm followup data on the Ponto boneanchored hearing implant from our tertiary referral centre Thirtyone consecutive patients with a mean age of 51 years who received the implant between October 2010 and December 2011 were included retrospectively in this study Implant loss skin reactions around the implant according to Holgers’ grading system revision surgery and abutment replacements were retrospectively gathered from the patients’ files as objective outcome measures To obtain information on subjective patient satisfaction the Glasgow Benefit Inventory GBI was used The mean followup period was 169 months range 121–252 months One implant was lost Over a total of 94 followup visits 21 skin reactions were observed in 16 patients Holgers grade 1 slight redness no need for treatment in 181 of the visitsand grade 2 redness and moist needing conservative treatment in 43 of the visits Four 6mm abutments 129 were replaced for a 9mm abutment during the followup period of which one 32 was in combination with revision surgery In one patient keloid formation around the implant was observed The GBI revealed a moderate subjective benefit The shortterm results with these percutaneous implants demonstrate a clinically stable implant with a low percentage of skin reactions that require treatment Longterm prospective followup data are needed to draw firmer conclusions
