This study evaluated a new endoscopic Le Fort I osteotomy technique, showing it preserves the descending palatal artery and reduces swelling. Further refinement may improve this minimally invasive surgical approach.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Minimally Invasive Surgical Techniques
  • Endoscopic Surgical Procedures

Background:

  • The Le Fort I osteotomy is a common surgical procedure for correcting midface deformities.
  • Conventional techniques can involve significant bleeding and postoperative swelling.
  • Limited access approaches may improve patient outcomes.

Purpose of the Study:

  • To evaluate a novel endoscopic technique for performing the Le Fort I osteotomy.
  • To assess the safety and efficacy of limited approach endoscopic Le Fort I osteotomy.
  • To compare outcomes with conventional open techniques.

Main Methods:

  • The technique was initially tested on cadavers, followed by application in two human patients.
  • Four small vertical incisions were utilized for endoscopic access.

  • Endoscopic visualization facilitated precise osteotomies of the maxilla, including the pterygomaxillary junction.

    • Main Results:

    • The endoscopic Le Fort I osteotomy was successfully performed in all cases.
    • Preservation of the descending palatal artery was achieved in all procedures due to endoscopic control.
    • Postoperative edema and swelling were reduced compared to conventional methods.

    Conclusions:

    • Endoscopic visualization enables safe osteotomy and preservation of the descending palatal artery, minimizing bleeding.
    • The endoscopic approach resulted in reduced postoperative edema and swelling.
    • While initial clinical cases took slightly longer, further development is expected to optimize the procedure.
