Key result
Minimally Invasive Ponto Surgery (MIPS) reduced the mean cost per patient by €77.83 compared to the linear incision technique with tissue preservation after 22 months of follow-up.
Why the study?
Differences in mean cost per patient between Minimally Invasive Ponto Surgery and the linear incision technique with tissue preservation had not been identified.
Does Minimally Invasive Ponto Surgery (MIPS) reduce perioperative and postoperative costs compared to linear incision technique with tissue preservation in adult patients eligible for unilateral bone conduction device surgery?

Yes
Does Minimally Invasive Ponto Surgery (MIPS) reduce perioperative and postoperative costs compared to linear incision technique with tissue preservation in adult patients eligible for unilateral bone conduction device surgery?
Mean Difference: 77.83
MIPS is an economically responsible technique that reduces mean cost per patient compared to LITT-P for bone conduction device implantation.
Supports MIPS adoption for cost efficiency in bone conduction implantation; extends RCT evidence to include economic outcomes.
OBJECTIVES: To identify differences in mean cost per patient between the Minimally Invasive Ponto Surgery (MIPS) and the linear incision technique with tissue preservation (LITT-P). STUDY DESIGN: Health economic cost analysis. SETTING: The analysis was performed in a randomized multicenter controlled trial cohort. PATIENTS: Adult patients eligible for unilateral bone conduction device surgery. INTERVENTIONS: MIPS versus LITT-P surgery for bone conduction device implantation. MAIN OUTCOME MEASURES: Perioperative and postoperative costs were identified and compared. RESULTS: The difference in mean cost per patient between both techniques was €77.83 in favor of the MIPS after 22 months follow-up. The mean costs per patient were lower in the MIPS cohort for surgery (€145.68), outpatient visits (€24.27), systemic antibiotic therapy with amoxicillin/clavulanic acid (€0.30) or clindamycin (€0.40), abutment change (€0.36), and abutment removal (€0.18). The mean costs per patient were higher for implant and abutment set (€18.00), topical treatment with hydrocortison/oxytetracycline/polymyxine B (€0.43), systemic therapy with azithromycin (€0.09) or erythromycin (€1.15), local revision surgery (€1.45), elective explantation (€1.82), and implant extrusion (€70.42). Additional analysis of scenarios in which all patients were operated under general or local anesthesia or with recalculation when using current implant survival rates showed that differences in mean cost per patient were also in favor of the MIPS. CONCLUSION: The difference between the MIPS and the LITT-P in mean cost per patient was €77.83 in favor of the MIPS after 22 months of follow-up. The MIPS is an economically responsible technique and could be promising for the future.

Strijbos et al. (2023) conducted an RCT in unilateral bone conduction device surgery. Minimally Invasive Ponto Surgery (MIPS) vs. Linear incision technique with tissue preservation (LITT-P) was evaluated on Mean cost per patient (MD €77.83). Minimally Invasive Ponto Surgery (MIPS) reduced the mean cost per patient by €77.83 compared to the linear incision technique with tissue preservation after 22 months of follow-up.
