Summary
This study presents a novel guided transoral approach for inferior alveolar nerve (IAN) repair, utilizing computer-assisted surgical guides. This technique offers precise and conservative access for IAN neurofibroma excision and reconstruction.
Area of Science:
- Oral and Maxillofacial Surgery
- Neurosurgery
- Medical Technology
Background:
- Traditional inferior alveolar nerve (IAN) surgeries present technical challenges and risk nerve damage.
- Computer-assisted virtual surgical planning and guides improve precision in craniomaxillofacial procedures.
Purpose of the Study:
- To describe a novel guided transoral approach for precise IAN access and repair.
- To evaluate the efficacy of a depth-controlled surgical guide for IAN procedures.
Main Methods:
- Utilized computer-assisted virtual surgical planning and a custom surgical guide with a depth control feature.
- Performed a guided transoral approach for inferior alveolar nerve neurofibroma excision.
- Reconstructed the IAN using an immediate peripheral nerve allograft.
Main Results:
- The novel guided approach provided safe and efficient access to the inferior alveolar nerve.
- The technique allowed for a conservative approach, minimizing damage to healthy nerve tissue.
- Successful excision of the neurofibroma and immediate nerve reconstruction were achieved.
Conclusions:
- A guided transoral approach with depth-controlled surgical guides is a precise and effective method for IAN repair.
- This technique minimizes iatrogenic damage and facilitates complex IAN reconstructions.
- This innovative method advances the surgical management of IAN pathologies.
