ENT · Complications of otitis media
Sample itemA child with chronic ear discharge develops deep retro-orbital pain on the same side and diplopia on looking toward that side. Which complication is this?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Petrous apicitis (Gradenigo's syndrome)
Infection of the petrous apex involves the trigeminal ganglion, causing deep facial or retro-orbital pain, and the abducens nerve, causing lateral rectus palsy. Together with ear discharge this is Gradenigo's triad. Treatment is antibiotics and mastoid surgery to drain the apex when needed.
Option by option
A. Otitic hydrocephalus
Otitic hydrocephalus presents with raised intracranial pressure and papilloedema rather than pain with sixth nerve palsy.
B. Bezold's abscess
Bezold's abscess is a neck collection deep to sternocleidomastoid from mastoid tip pus.
C. Petrous apicitis (Gradenigo's syndrome) (correct)
Correct. Ear discharge, trigeminal pain and abducens palsy are the triad.
D. Lateral sinus thrombophlebitis
Lateral sinus thrombophlebitis causes spiking fever and a positive Griesinger sign, not an abducens palsy.
