Bilateral sagittal split ramus osteotomy combined with mandibular angle resection effectively corrects facial deformities. This surgical approach safely reshapes the jaw angle, improving patient outcomes without complications.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthognathic Surgery
- Facial Plastic Surgery
Background:
- Mandibular prognathism and retrognathism often present with a prominent mandibular angle.
- Bilateral sagittal split ramus osteotomy (BSSRO) is a standard procedure for correcting these jaw discrepancies.
- A prominent mandibular angle can negatively impact facial aesthetics.
Purpose of the Study:
- To evaluate the efficacy and safety of BSSRO combined with mandibular angle resection.
- To assess the impact of this combined surgical technique on mandibular angle dimensions.
- To report clinical experience with this modified surgical approach.
Main Methods:
- Retrospective review of eleven patients treated between July 2014 and December 2016.
- Bilateral sagittal split ramus osteotomy (BSSRO) followed by mandibular angle ostectomy via a medial approach.
- Pre- and post-operative measurements of mandibular angle dimensions were analyzed.
Main Results:
- Significant reduction in mandibular angle measurements was observed post-surgery (p < 0.05).
- No instances of unanticipated fractures or mandibular hematoma were reported.
- The combined procedure demonstrated effective correction of facial deformities.
Conclusions:
- Bilateral sagittal split ramus osteotomy (BSSRO) with medial mandibular angle ostectomy is a safe and effective technique.
- This combined approach successfully corrects facial deformities associated with mandibular prognathism/retrognathism and prominent mandibular angles.
- The procedure offers predictable aesthetic and functional improvements.
