Sagittal split osteotomy with virtual surgical planning offers an effective, tissue-saving method for removing benign mandibular lesions. This approach preserves bone and neurovascular structures, avoiding extensive reconstruction and restoring full jaw function.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Surgical Oncology
  • Biomedical Engineering

Background:

  • Benign intramandibular lesions often necessitate extensive surgical removal, including resection and reconstruction.
  • Traditional methods carry risks of significant bone loss and functional deficits.

Observation:

  • A protocol utilizing sagittal split osteotomy (SSO) combined with virtual surgical planning (VSP) was implemented for benign mandibular lesions.
  • Computed tomographic data were used for precise virtual delineation of lesions and the inferior alveolar nerve canal.

Findings:

  • SSO with VSP enabled precise lesion access while preserving mandibular cortical bone and the inferior alveolar neurovascular bundle in all patients.
  • Post-surgery, patients experienced no pathologic fractures, malocclusion, or significant paresthesia, and avoided bone grafting.

Implications:

  • SSO with VSP presents a viable, less invasive alternative to traditional resection for benign mandibular lesions.
  • This technique minimizes morbidity, preserves jaw integrity, and restores masticatory function, potentially reducing the need for complex reconstructive procedures.
