Summary

The sphenoparietal sinus transposition (SPST) technique widens surgical access for deep brain lesions. This method mobilizes superficial sylvian veins, improving exposure for complex cranial operations.

Area of Science:

Neurosurgery
Surgical Anatomy

Background:

Transsylvian approaches are crucial for complex cranial surgeries like cerebrovascular, skull base, and neuro-oncology procedures.
Deep lesions near the basilar apex or midbrain can be challenging due to superficial sylvian veins (SSV) obstructing surgical corridors.
The sphenoparietal sinus transposition (SPST) technique is presented to address these exposure limitations.

Keywords:

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
