Description

The Choanae are the posterior nasal aperture, separated by the vomer.

It is the opening between the nasal cavity and the nasopharynx.

It is therefore not a structure but a space bounded as follows:

  • anteriorly and inferiorly by the horizontal plate of palatine bone,
  • superiorly and posteriorly by the sphenoid bone
  • laterally by the medial pterygoid plates.
