The objective of the study was to evaluate postoperative pain following a transcutaneous active conductive hearing implant. 27 patients undergoing Bonebridge (BB) bone conduction implantation were evaluated with two pain-related questionnaires. The Headache Impact Test (HIT-6) was used to measure the degree of disability including none or little impact (aecurrency sign49), mild (50-55), moderate (56-59), and severe (aeyen60). The Brief Pain Inventory (BPI) was used to assess pain severity score and function interference (0 = no pain to 10 = worst pain); meaningful pain was considered to be aeyen3. The impact of surgical factors on postoperative pain was analyzed. Postoperative BB pain results were compared with 11 Vibrant Soundbridge (TM) (VSB) and 103 cochlear implant (CI) users. The mean pre- and postoperative HIT-6 scores for BB implantation were 42.6 and 41.8, respectively and the mean preoperative BPI pain severity score changed from 0.6 to 0.9 postoperatively, whereas the preoperative interference score changed from 0.1 to 0.3. None of the mean postoperative values revealed significant pain. The retrosigmoid approach, the need for dural or sinus compression, and the use of bone conduction implant lifts had no significant impact on pain scores. The mean postoperative HIT-6 pain scores for patients with BB, VSB, and CI were 41.8, 46.4, and 42.8, respectively, with the differences not being significant. BB implantation causes no significant postoperative pain irrespective of sinus or dura compression. Pain scores were similar to those experienced by patients with other transcutaneous auditory implants such as middle ear or CIs.
