A modified quadrangular osteotomy effectively prevented infraorbital nerve issues in six patients. This surgical refinement yielded excellent functional and aesthetic outcomes.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Plastic Surgery
  • Neurosurgery

Background:

  • Quadrangular osteotomy is a surgical technique used in facial reconstruction.
  • Potential complications include infraorbital nerve dysesthesia, impacting patient quality of life.
  • Minimizing nerve damage is crucial for successful surgical outcomes.

Purpose of the Study:

  • To evaluate a modified quadrangular osteotomy technique.
  • To assess the efficacy of the modification in preventing infraorbital nerve dysesthesia.
  • To determine the functional and aesthetic results of the modified procedure.

Main Methods:

  • A modified quadrangular osteotomy was performed on six patients.
  • The specific modifications aimed at protecting the infraorbital nerve were implemented.

  • Patient outcomes were assessed for nerve function and aesthetic appearance.

    • Main Results:

    • The modified technique successfully avoided dysesthesia of the infraorbital nerve in all patients.
    • Excellent functional recovery was observed post-surgery.
    • High patient satisfaction was reported regarding aesthetic results.

    Conclusions:

    • The modified quadrangular osteotomy is a safe and effective surgical approach.
    • This technique significantly reduces the risk of infraorbital nerve injury.
    • The procedure offers excellent functional and aesthetic benefits for patients.
