Summary
This study compares the Minimally Invasive Ponto Surgery (MIPS) technique to the linear incision technique for bone conduction hearing implants (BCHI). It evaluates outcomes like peri-abutment dermatitis (PAD), skin sensibility, and esthetics to determine the superior BCHI surgical approach.
Area of Science:
- Otolaryngology
- Neurosurgery
- Biomedical Engineering
Background:
- Less invasive surgical techniques for bone conduction hearing implants (BCHI) with soft tissue preservation are gaining traction.
- The linear incision technique has shown promising results regarding peri-abutment dermatitis (PAD), esthetics, and skin sensibility.
- The Minimally Invasive Ponto Surgery (MIPS) technique is a novel, standardized approach for BCHI placement designed to minimize soft tissue trauma.
Purpose of the Study:
- To compare the efficacy and safety of the MIPS technique against the linear incision technique for BCHI surgery.
- To evaluate and quantify factors including skin sensibility, dehiscence, skin overgrowth, and cosmetic outcomes.
- To assess the incidence of peri-abutment dermatitis (PAD) within the first 3 months post-implantation.
Main Methods:
- A multicenter randomized controlled trial involving 62 participants with a 2-year follow-up period.
- Comparison of MIPS technique versus linear incision technique for BCHI placement.
- Collection of swabs and skin biopsies for bacterial profiling and inflammatory cytokine expression to understand PAD.
Main Results:
- The study is designed to compare the incidence of PAD between the two surgical techniques.
- Secondary objectives include assessing wound healing, pain, implant stability, extrusion rates, and esthetic appeal.
- Tertiary objectives focus on other PAD-related factors and a health economic evaluation.
Conclusions:
- This trial represents the first direct comparison of the MIPS technique with the established linear incision technique for BCHI.
- Novel parameters and sampling methods will provide insights into predicting outcomes and complications associated with BCHI surgery.
