Summary
Intraoral L-shaped osteotomy effectively reduces the zygomatic bone, leading to significant changes in maxillary sinus volume. This surgical approach for zygomatic reduction is safe and complication-free.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Anatomical Reconstruction
Context:
- Zygomatic reduction surgery aims to reshape the cheekbones.
- Intraoral approaches minimize external scarring.
- Midface L-shaped osteotomy is a specific surgical technique.
Purpose:
- To evaluate the outcomes of zygomatic reduction using midface L-shaped osteotomy via an intraoral approach.
- To assess changes in maxillary sinus volume post-surgery.
- To identify any complications associated with the procedure.
Summary:
- A study of 67 patients undergoing zygomatic reduction with intraoral L-shaped osteotomy found satisfactory results.
- CT scans of 52 patients showed a significant reduction in maxillary sinus volume 12 months post-operation (P<0.05).
- No instances of infection or dental pulp necrosis were reported.
Impact:
- This study demonstrates the efficacy and safety of the intraoral L-shaped osteotomy technique for zygomatic reduction.
- The findings suggest that maxillary sinus exposure during this procedure does not lead to complications.
- The technique offers a viable option for facial contouring with minimal visible scarring.
