ENT · Nose and paranasal sinuses: contents of pterygopalatine fossa
Sample itemA surgeon expects to see the terminal part of the maxillary artery and a parasympathetic ganglion in the pterygopalatine fossa. Which ganglion is it?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Sphenopalatine (pterygopalatine) ganglion
The pterygopalatine fossa contains the third part of the maxillary artery, the maxillary nerve and the sphenopalatine ganglion, which relays parasympathetic fibres from the greater petrosal nerve to the lacrimal and nasal glands. It communicates with the nose through the sphenopalatine foramen. Surgery for posterior epistaxis targets the artery here.
Option by option
A. Ciliary ganglion
The ciliary ganglion is in the orbit.
B. Submandibular ganglion
The submandibular ganglion hangs from the lingual nerve.
C. Sphenopalatine (pterygopalatine) ganglion (correct)
Correct. This ganglion sits in the fossa.
D. Otic ganglion
The otic ganglion lies below the foramen ovale and supplies the parotid.
