ENT Core Concepts and Principles 5

Question 1

Primary acquired cholesteatoma most commonly starts in which location?

Pars flaccida (Prussak's space)

Answer

Retraction of the pars flaccida into Prussak's space is the classic origin of primary acquired cholesteatoma.

Question 2

Ludwig angina most commonly comes from which source of infection?

Accepted Answer

Mandibular second or third molar

Answer

The roots of the lower molars sit below the mylohyoid line, so infection spreads into the submandibular space.

Question 3

Which semicircular canal is most commonly involved in benign paroxysmal positional vertigo?

Accepted Answer

Posterior

Gravity makes otoconia settle mostly in the posterior canal, which is diagnosed with Dix-Hallpike and treated with the Epley maneuver.

Question 4

An adolescent male with recurrent unilateral epistaxis and nasal obstruction most likely has which lesion?

Accepted Answer

Juvenile nasopharyngeal angiofibroma

JNA is a vascular tumor of adolescent males that arises near the sphenopalatine foramen, so biopsy is avoided.
