Dentistry · Oral anatomy: parotid and facial nerve
Sample itemIn parotid surgery, which structure serves as the surgical plane separating the superficial and deep lobes of the gland?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. The facial nerve and its branches
The facial nerve enters the gland and divides within it, lying between the superficial and deep lobes. Surgeons identify it first to avoid facial paralysis during parotidectomy.
Option by option
A. The auriculotemporal nerve
The auriculotemporal nerve passes behind the joint and is not the dividing plane.
B. The masseteric fascia
The fascia lies over the gland and masseter.
C. Stensen's duct
The duct drains the gland but does not divide the lobes.
D. The facial nerve and its branches (correct)
Correct. The nerve plane separates the lobes.
