Summary
A modified sagittal split osteotomy provides safe access to central mandibular pathologies, avoiding inferior alveolar nerve damage and bone loss. This technique offers a promising alternative for treating osteomas, cysts, and impacted teeth.
Area of Science:
- Oral and Maxillofacial Surgery
- Surgical Innovation
- Mandibular Reconstruction
Background:
- Central mandibular pathologies pose surgical access challenges due to the inferior alveolar nerve (IAN) and extensive bone removal requirements.
- Traditional approaches often involve bone grafting, leading to potential resorption, graft rejection, and mandibular defects.
- Damage to the IAN is a significant complication, causing profound neurological deficits.
Purpose of the Study:
- To present a modified sagittal split osteotomy technique for accessing central mandibular pathologies.
- To evaluate the efficacy and safety of this modified approach in preventing complications associated with IAN and bone structure.
Main Methods:
- Modification of the traditional sagittal split osteotomy.
- Surgical intervention for a central osteoma impinging on the IAN.
- Assessment of surgical outcomes, focusing on IAN function and bone integrity.
Main Results:
- Successful removal of a central mandibular osteoma using the modified technique.
- Absence of comorbidities such as paraesthesia or loss of bone structure.
- Preservation of IAN integrity and mandibular structural integrity.
Conclusions:
- The modified sagittal split osteotomy is a viable and safe technique for accessing central mandibular pathologies.
- This approach effectively mitigates risks of IAN damage and bone resorption associated with traditional methods.
- The technique holds potential for treating benign cysts and complex impacted teeth in the central mandible.
