Anaesthesia · Regional anaesthesia: scalp block
Sample itemA scalp block for an awake craniotomy includes which of the following nerves?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Greater occipital nerve
The scalp block targets the supraorbital, supratrochlear, zygomaticotemporal, auriculotemporal, lesser occipital and greater occipital nerves. These cover the sensory supply of the scalp and are blocked at the sites where they emerge. Cranial nerves such as the facial, glossopharyngeal and vagus are not involved.
Option by option
A. Greater occipital nerve (correct)
Correct. The greater occipital nerve supplies the posterior scalp.
B. Vagus nerve
The vagus nerve has no role in scalp sensation.
C. Facial nerve
The facial nerve is mainly motor to the face.
D. Glossopharyngeal nerve
The glossopharyngeal nerve supplies the pharynx.
