QUESTION

Auriculopalpebral nerve block results into?

OPTIONS

(A) Loss of sensation of eyelids
(B) Motor Paralysis of eyelids
(C) Blockade of sensory and motor nerve
(D) None of these

ANSWER

(B) Motor Paralysis of eyelids

EXPLANATION

The auriculopalpebral branch of the facial nerve supplies motor function to the eyelid-closing muscle, so its block prevents blinking. Sensation is carried by branches of the trigeminal nerve; accordingly this block is not sensory loss or a combined sensory and motor block.
