Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthognathic Surgery
  • Surgical Anatomy

Background:

  • Bilateral sagittal split osteotomy (BSSO) is a standard procedure for correcting facial deformities.
  • A known complication of BSSO is mandibular notching, affecting the lower border's contour.
  • This notching can cause aesthetic concerns for patients.

Purpose of the Study:

  • To present a modified surgical technique for BSSO.
  • To address and mitigate the risk of mandibular notching following BSSO.
  • To improve the aesthetic outcomes of orthognathic surgery.

Main Methods:

  • Description of a modified vertical osteotomy cut technique during BSSO.
  • Comparison with standard BSSO procedures (implied).
  • Focus on surgical technique modification to prevent specific complication.

Main Results:

  • The modified vertical osteotomy cut is proposed as a solution to prevent mandibular notching.
  • This technique aims to maintain the smooth contour of the inferior mandibular border.
  • Anticipated reduction in patient-reported aesthetic concerns related to notching.

Conclusions:

  • A modified vertical osteotomy cut during BSSO is recommended.
  • This modification can effectively overcome the complication of mandibular notching.
  • The technique offers a way to enhance patient satisfaction after orthognathic surgery.
