Living with Aplasia of the nose

An extremely rare condition present from birth in which the nose is missing or underdeveloped.

Understanding Aplasia of the nose

Aplasia of the nose is an extremely rare condition present from birth in which part or all of the nose is missing.

It ranges from missing outer nose structures (hyporrhinia) to a missing outer nose, nasal airways, and smell nerves (arrhinia). It can affect one or both sides. It often causes trouble breathing and may need surgery. Related differences can include wide-set or small eyes, eyelid gaps, facial clefts, and small ears. It is seen during pregnancy and in newborns.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Trouble breathing (respiratory distress)
  • Missing or underdeveloped nasal bone and septum
  • Wide-set eyes (hypertelorism)
  • Very small eyes (microphthalmia)
  • Gaps in the eyelid (coloboma)
  • Small ears (microtia)

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

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include ear, nose, and throat specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
