ENT · Ear and audiology: foramen of Huschke
Sample itemA 3-year-old child has a normal canal, and a defect is noted in the anteroinferior bony canal wall at the tympanic plate. Which statement about the foramen of Huschke is correct?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. It is a developmental defect that normally closes by about 5 years of age
The tympanic plate ossifies from several centres, and a deficiency may persist in early childhood as the foramen of Huschke. It normally closes by 4 to 5 years. If it persists it allows spread of infection or a tumour between the canal and parotid and may cause herniation of the gland into the canal.
Option by option
A. It transmits the chorda tympani
The chorda tympani passes through the iter chordae anterius and posterius.
B. It is a developmental defect that normally closes by about 5 years of age (correct)
Correct. It is a normal childhood defect that closes by about 5 years.
C. It is a defect that normally appears at 40 years
It is a persistent childhood defect, not an adult one.
D. It lies in the pars flaccida of the drum
It is part of the tympanic plate of the bony canal, not the drum.
