Congenital malformations of the auricle

From WikiLectures

Classification of deformities according to Roger[edit | edit source]

Classification according to Tanzer[edit | edit source]

  • Anocia (complete absence of pinna)
  • complete hypoplasia (microcia) with / without atresia of the external auditory canal
  • hypoplasia of the middle 1/3 of the ear
  • hypoplasia of the upper 1/3 of the ear: "constricted ear" (overhanging pinna + cone-shaped ear), cryptocia, hypoplasia of the entire upper 1/3
  • removed bolts

Other deformities[edit | edit source]

  • appendices praeauriculares (rudimentary growths around the pinna)
  • fistulas incomplete (lead a short distance) / complete (lead to the mouth or pharynx)

Associated diseases[edit | edit source]

Treatment[edit | edit source]

  • operation changing the shape of the cartilaginous part of the auricle → change of soft tissues.
  • most often surgery for detached auricles
  • in case of non-development of the auricle, we reconstruct the cartilaginous part with cartilage from the rib + soft tissue by tissue expansion and local displacements
