OBJECTIVE: To compare the 3-year outcomes of the modified minimally invasive Ponto surgery (m-MIPS) to both the original MIPS (o-MIPS) and linear incision technique with soft tissue preservation (LIT-TP) for inserting bone-anchored hearing implants (BAHIs).
STUDY DESIGN: Prospective study with three patient groups: m-MIPS, o-MIPS, and LIT-TP.
SETTING: Tertiary referral center.
PATIENTS: In the m-MIPS group, 24 patients with 25 implants were enrolled. The o-MIPS and LIT-TP groups included 25 patients (25 implants) each.
INTERVENTIONS: The patients underwent BAHI surgery using m-MIPS, o-MIPS, or LIT-TP.
MAIN OUTCOME MEASURES: Implant survival and implant stability were compared between all groups. Soft tissue status, skin sensibility, subjective numbness, and hearing-related quality of life (HRQoL) were compared between m-MIPS and LIT-TP and o-MIPS and LIT-TP, respectively.
RESULTS: Implant survival was comparable between m-MIPS and LIT-TP (96 versus 100%), with o-MIPS showing nonsignificant lower survival (88%). Both MIPS groups exhibited fewer (adverse) skin reactions, better skin sensibility, and less subjective numbness than LIT-TP throughout visits. At 3 years, soft tissue status, sensibility, and numbness were comparable between groups. Device use was consistent among groups (83-86% daily users). All groups demonstrated significant improvement in HRQoL post-surgery based on GBI, GHSI, and APHAB total scores.
CONCLUSIONS: Compared with LIT-TP, m-MIPS showed comparable long-term implant survival, fewer (adverse) skin reactions, and earlier sensibility and numbness recovery. M-MIPS resulted in favorable clinical and QoL outcomes with low intra- and postoperative complication rates until 3 years after surgery. It is therefore considered a safe technique for BAHI insertion. Moreover, with a shorter surgery time and the ability to operate under local anesthesia in a controlled outpatient setting, m-MIPS appears to be a more efficient alternative to LIT-TP.
