Living with Anotia

A condition present from birth in which the outer ear and ear canal are missing.

Understanding Anotia

Anotia is a condition present from birth in which the outer ear and ear canal are completely absent.

It is the most extreme form of microtia, which means a very small outer ear. It can come with hearing loss caused by sound not reaching the inner ear (conductive hearing loss), attention difficulties, and delayed language development. It is noticed in newborns and infants.

Signs & symptoms

GARD doesn't list specific symptoms for this condition, but its summary describes these features:

  • Complete absence of the outer ear
  • Absent ear canal
  • Hearing loss from sound not reaching the inner ear
  • Attention difficulties
  • Delayed language development

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 and genetic specialists.

  3. Ask which tests can help

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