  "term": "Anotia",
  "field": "Chemistry",
  "definition": "A congenital malformation characterized by the complete absence of the external ear, also known as the pinna. In developmental toxicology, this condition is studied as a severe structural birth defect that results from a disruption of embryonic development. Anotia is a rare condition, often occurring as part of a broader syndrome affecting craniofacial structures, and is distinct from microtia, which is the underdevelopment of the external ear.",
