Summary
Endoscopic vertical ramus osteotomy offers a feasible minimally invasive approach for correcting mandibular deformities. This technique demonstrates effective outcomes for prognathism and malocclusion with minimal complications.
Area of Science:
- Oral and Maxillofacial Surgery
- Minimally Invasive Surgical Techniques
- Orthognathic Surgery
Background:
- Minimally invasive surgery offers significant patient benefits.
- Endoscopic techniques are increasingly being applied to complex surgical procedures.
- Mandibular deformities require effective surgical correction.
Purpose of the Study:
- To present early outcomes of endoscopic mandibular orthognathic surgery.
- To evaluate the feasibility of endoscopic vertical ramus osteotomy.
- To assess the efficacy in treating mandibular prognathism and malocclusion.
Main Methods:
- Retrospective evaluation of 14 patients undergoing endoscopic vertical ramus osteotomy and rigid fixation.
- Procedures included treatment for mandibular prognathism, post-traumatic malocclusion, and other pathologies.
- Evaluation involved clinical examinations, lateral cephalograms, and panoramic radiographs.
Main Results:
- Mean operative time was 37 minutes per side.
- All cases achieved the planned occlusal results.
- Radiographic imaging confirmed correct ramus/condyle and mandibular positioning.
Conclusions:
- Endoscopic vertical ramus osteotomy with rigid fixation is a viable surgical option.
- The technique is effective for correcting various mandibular deformities.
- Early results suggest feasibility and positive outcomes.
