Abstract
Background
The soft tissue dissection for the middle fossa approach requires adequate management of the neuro, vascular, and muscular structures in order to maximize exposure and diminish morbidities.
Methods
An incision anterior to the tragus is performed, extending from the zygomatic process to the superior temporal line. The superior temporal artery is exposed, followed by a subfascial dissection of the frontalis nerve. The temporal muscle is dissected and released from the zygoma. All cranial landmarks are exposed for the 5 × 5 cm temporal fossa craniotomy.
Conclusion
This novel approach provides a safe and adequate access to perform an extended middle fossa craniotomy.

Key points
1. Supine position with the head turned to the contralateral side and parallel to the floor.
2. Linear incision 1 cm anterior to the tragus, extending from 1 cm below the zygomatic process to 1 cm above the superior temporal line.
3. Exposure of STA with coagulation and cutting of the parietal branch.
4. Subgaleal dissection exposes the junction between the superior orbital rim and the superior temporal line at its anterosuperior limit, and the root of the zygomatic process posteroinferiorly.
5. Subfascial dissection.
6. Superficial temporalis fascia and associated fat pad are reflected anteriorly.
7. Temporal muscle subperiosteal dissection from posterior to anterior and from inferior to superior.
8. Anterior dissection of the temporal muscle.
9. Identify all cranial landmarks exposed.
10. Perform a 5 × 5 cm temporal fossa craniotomy.
