The objectives of the study were to determine the incidence of skin reactions and complications associated with bone-anchored hearing aid (BAHA) implantation. The study is a retrospective case review done in a tertiary referral center. One hundred thirty-eight consecutive patients between 1998 and 2008 underwent implantation of a BAHA and were regularly seen for follow-up. Indications included conductive or mixed hearing loss where a hearing aid cannot be used and since 2000 also had contralateral single-sided perceptive hearing loss. BAHA implantation was done by creating a pedicled flap using the skin flap dermatome technique. Postoperative incidence of skin reactions and complications were measured. Significant postoperative complications requiring revision surgery occurred 37 times in 30 patients. Normal skin healing was seen in 52 patients (63.4%), while abnormal skin healing occurred in 30 patients (36.6%). This study showed that skin problems occur more often than expected. Because of the skin problems with the skin flap technique, the authors have switched to the linear incision technique, hoping to decrease the incidence of skin problems.
