Osseointegrated implants in children: Experience from our first 100 patients

This study was undertaken on 100 children aged 16 years or under intended f or installation of osseointegrated implants. Of these, 76 had implants inst alled for bone-anchored hearing aids or prostheses. The main indication for implant installation was a bilateral ear malformation. Surgery was general ly performed as a two-stage procedure with a healing time of 3 to 4 months in between. Available bone thickness was on average 2.5 mm, and lack of bon e necessitated bone augmentation in 12 patients, Thirty-nine percent of imp lants were installed in contact with the dura, sigmoid sinus, or an air cel l, Implant failures were 5.8% of 170 inserted fixtures. Adverse skin reacti ons appeared in 9.1% of patients over a 21-year follow-up period, Revision surgery was undertaken in 22% of patients because of appositional growth of the temporal bone, Of the 24 children considered but not found suitable fo r osseointegration surgery, plastic surgery was considered a better option, or growth of the temporal bone was awaited, It is concluded that the rate of implant failure is lower in children; the frequency of skin reactions is the same as in adults, but revision surgery is more common in young patien ts because of new bone formation. Our clinical experience supported by the data presented in this article suggests that the concept could be used with good functional and aesthetic results in children.
