Congenital deformities of the auricle

From WikiLectures

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

Classification according to Tanzer[edit | edit source]

  • Anotia (complete absence of the auricle)
  • complete hypoplasia (mikrotia) with / without outer ear canal atrophy
  • hypoplasia of middle 1/3 of the ear
  • hypoplasia of upper 1/3 of the ear: „constricted ear“ (overhanging earlobe + cone-shaped ear), cryptotia, hypoplasia of entire upper 1/3
  • sticking out auricle

Other deformities[edit | edit source]

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

Associated disorders[edit | edit source]

Treatment[edit | edit source]

  • surgery changing the shape of the cartilage of the pinna → soft tissue change
  • most common are operations of sticking out auricles
  • in case of non-development of the auricle we reconstruct the cartilage part with cartilage from the rib + soft tissues by tissue expansion and local shifts
