ENT · Nose: nasal valve

Sample item

The narrowest part of the nasal airway, forming the main site of resistance to airflow, is which area?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Internal nasal valve

The internal nasal valve lies between the caudal edge of the upper lateral cartilage and the septum with an angle of about 10 to 15 degrees. Collapse causes obstruction on inspiration, and the Cottle manoeuvre tests it.

Option by option

  • A. Choana

    The choana is a posterior opening and not the narrowest segment.

  • B. External nasal valve

    The external valve is the nostril aperture and is wider.

  • C. Internal nasal valve (correct)

    Correct. The internal valve is the narrowest part.

  • D. Inferior meatus

    The inferior meatus is a space under the turbinate.
