Summary
Guide plate-assisted surgery precisely corrects mandibular asymmetry in Asian women, significantly improving facial symmetry and patient satisfaction. This safe and effective method enhances the desired mandibular appearance.
Area of Science:
- Plastic Surgery
- Craniofacial Surgery
- Aesthetic Surgery
Background:
- Asian women often desire a more refined mandibular contour.
- Mandibular angle hypertrophy (MAH) can cause facial asymmetry.
- Correction of MAH aims to improve facial aesthetics and symmetry.
Purpose of the Study:
- To evaluate the effectiveness of guide plate-assisted mandibular angle ostectomy (MAO) in improving mandibular symmetry.
- To assess the precision of the surgical technique in Asian female patients with MAH.
- To determine patient satisfaction with the surgical outcomes.
Main Methods:
- Retrospective cohort study of 11 patients with MAH and asymmetry.
- Preoperative planning using CT data and intraoperative guide plate assistance.
- Postoperative CT analysis to measure symmetry and surgical precision (osteotomy distance, angle, volume).
- Patient satisfaction assessed using a Likert Scale at 6-month follow-up.
Main Results:
- Surgical precision was within 2 mm of the preoperative plan.
- Mandibular asymmetry was significantly reduced from 15.09% to 2.74%.
- Patient satisfaction was high, averaging 4.5 out of 5.
Conclusions:
- Guide plate-assisted MAO is an effective and precise surgical technique.
- This method offers a safe option for correcting mandibular asymmetry.
- The procedure leads to high levels of patient satisfaction.
