Background And Objectives:
This study aimed to evaluate the feasibility of a minimal inverted-J incision for bone-anchored hearing aid (BAHA) Attract implantation. Classical large incisions often result in prolonged surgical time and wound-related complications. A linear incision can lead to an incision scar overlapping the implanted magnet, resulting in wound complications, magnet instability, and problems with external device attachment. Our novel incision method overcomes the limitations of both incision methods.
Subjects And Methods:
We assessed the outcomes of patients who underwent BAHA Attract implantation using a minimal inverted-J incision, which was designed to provide adequate exposure while avoiding excessive incision. The total surgery duration, wound healing, and implant stability were evaluated based on hearing outcomes and compared with those of patients who underwent a classical incision.
Results:
The minimal inverted-J incision and classical incision groups demonstrated no significant differences in surgical time (32.7±6.3 min vs. 36.9±5.4 min, p=0.056), postoperative major wound complications (6.3% vs. 20%, p=0.176), and hearing outcomes (51.8±31.1 dB vs. 49.3±27.8 dB, p=0.585); however, the trends consistently showed that the minimal inverted-J incision group was either superior or comparable to the other groups.
Conclusions:
Our novel incision technique for BAHA Attract implantation addresses the limitations associated with both the classical and minimal linear incision approaches.
