Feasibility of Minimal Inverted-J Incision for Bone-Anchored Hearing Aid Attract Implantation

Area of Science:

• Otolaryngology
• Surgical Innovation
• Medical Devices

Background:

• Classical bone-anchored hearing aid (BAHA) incisions can lead to prolonged surgery and wound complications.
• Linear incisions for BAHA Attract may cause scar overlap, wound issues, and device instability.
• A novel minimal inverted-J incision aims to mitigate these limitations.

Purpose of the Study:

• To evaluate the feasibility of a minimal inverted-J incision for BAHA Attract implantation.
• To compare surgical outcomes between the novel incision and classical approaches.

Main Methods:

• Retrospective analysis of patients undergoing BAHA Attract implantation.
• Comparison of surgical duration, wound healing, and implant stability between minimal inverted-J and classical incisions.
• Assessment of hearing outcomes in both groups.

Main Results:

• No significant differences in surgical time (32.7±6.3 min vs. 36.9±5.4 min, p=0.056).
• Postoperative major wound complications were comparable (6.3% vs. 20%, p=0.176).
• Hearing outcomes showed no significant difference (51.8±31.1 dB vs. 49.3±27.8 dB, p=0.585), with trends favoring the novel incision.

Conclusions:

• The minimal inverted-J incision is a viable alternative for BAHA Attract implantation.
• This technique effectively addresses limitations of classical and linear incisions.
• The novel approach offers comparable or superior outcomes in surgical time, wound healing, and hearing results.
