OBJECTIVE: This study investigated the safety of utilizing further posterior placement than recommended by the manufacturer of a bone conduction implant and compared its auditory performance to that of implants placed in the recommended location.
METHOD: This is a prospective cohort study included children (aged ≤18 years) who received the Osia System implantation between January 2022 and May 2024. We recorded demographics, comorbidities, radiological imaging findings, operative details, pre- and postoperative audiological testing (audiometric measurements, speech discrimination, and sound localization), surgical outcomes, and complications. We compared the outcomes of placing the BI300 at 5.5 cm and 7 cm from the external auditory canal.
RESULTS: This study included 23 children (29 implants) with a median implantation age of 7 years (range 3-17 years). Six patients underwent simultaneous bilateral implantation, and none of the patients experienced serious complications. Group 1 (5.5 cm) had 12 implants, and Group 2 (7 cm) had 17 implants. There was no difference in median pure-tone average postoperatively, 21.67 dB HL for group 1 and 20.83 dB HL for group 2 (p = 0.66). Speech discrimination was comparable between the groups (92 % and 95 %, respectively). Sound localization improved significantly in both groups (Group 1: from 26 % to 90 % and Group 2: from 30 % to 85 %, respectively), without any statistically significant difference between the groups.
CONCLUSION: Placing the BI300 at 7 cm posterior to the external auditory canal yielded an auditory performance similar to the manufacturer's recommendation of 5.5 cm. Postero-inferior incision approach, can be an option for children prior to auricular reconstruction.
LEVEL OF EVIDENCE: Level 2 evidence: prospective cohort study.
