Summary
This modified preauricular approach offers direct skull base access by repositioning the zygomatic arch and coronoid process. It simplifies surgery for temporal and infratemporal fossa lesions with minimal morbidity.
Area of Science:
- Neurosurgery
- Otolaryngology
- Head and Neck Surgery
Background:
- The preauricular approach is a standard surgical technique for accessing the skull base.
- Limitations exist in achieving optimal exposure of the temporal and infratemporal fossae.
Observation:
- A modified preauricular approach involves sectioning the zygomatic arch and coronoid process.
- The temporal muscle is retracted superiorly, providing unobstructed access.
- Vascular control of the internal carotid artery is maintained.
Findings:
- This technique was successfully applied in seven patients with skull base lesions.
- No operative mortality was observed.
- Temporary restriction of mandibular opening occurred in two patients.
Implications:
- This modified approach simplifies surgical access to the temporal and infratemporal regions.
- It potentially reduces the need for extensive reconstruction.
- Offers a safe and effective alternative for specific skull base pathologies.
