Summary
Computer-assisted navigation for rhinoplasty osteotomies is feasible and effective, improving precision and patient outcomes. This innovative approach enhances surgical accuracy in nasal bone modification with minimal complications.
Area of Science:
- Plastic Surgery
- Medical Technology
- Surgical Innovation
Background:
- Rhinoplasty is a common aesthetic surgery globally, with osteotomies crucial for nasal bone structure modification.
- Precision and minimal complications are paramount in osteotomy procedures.
- Computer-assisted navigation systems are advancing but their application in rhinoplasty is still evolving.
Purpose of the Study:
- To assess the feasibility of computer-assisted planning and navigation for osteotomies in primary rhinoplasty.
- To evaluate the safety and efficacy of this novel approach.
- To follow the IDEAL Phase 2a framework for study design.
Main Methods:
- A retrospective study involving 20 patients undergoing primary rhinoplasty at a tertiary center.
- Utilized navigation systems for planning and executing lateral, medial, and transverse osteotomies.
- Employed real-time guidance with a tracked piezoelectric instrument.
Main Results:
- All 20 procedures were successfully completed using navigation without reverting to traditional methods.
- Osteotomy execution became progressively easier, though transverse osteotomies remained more challenging.
- Preoperative planning time decreased significantly, and patient-reported outcomes (FACE-Q, NOSE, MiRa scales) showed marked improvement. Minor device-related blisters occurred in two cases.
Conclusions:
- Computer-assisted navigation for nasal osteotomies is a feasible, safe, and effective technique.
- This method enhances surgical precision and improves patient outcomes in primary rhinoplasty.
- Further large-scale prospective studies are recommended to validate findings and compare with traditional techniques.
