Living with Paramedian nasal cleft

A rare difference in how the nose formed before birth, with a notch or split in the side of the nose.

Understanding Paramedian nasal cleft

Paramedian nasal cleft is a rare developmental difference in which the nose has a notch or split on one or both sides.

It can range from a small notch to larger clefts of the nostril wing, and sometimes small cysts or sinuses (tiny channels) in the middle of the nose. It may occur alone or with a cleft lip or other facial differences. The top and tip of the nose are usually well formed.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. The summary describes:

  • Notch or split in the nostril
  • Slightly bent wall inside the nose
  • Small cysts or channels in the middle of the nose
  • Cleft lip (sometimes)
  • Wide-set eyes (sometimes)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
