Synonym(s): TECA


Introduction

  • Removal of the entire external ear canal, ie vertical and horizontal ear canals.
  • To remove chronic pain and inflammation associated with chronic ear disease, establish temporary drainage of tympanic bullae and peri-auricular tissues in case of infection.
  • Prevent future episodes of otitis externa.

Uses

  • Chronic proliferative changes in the ear canal Skin: otitis externa.
  • Complete horizontal ear canal stenosis Otitis externa chronic - stenosis (hyperplastic changes).
  • Para-aural abscessation (eg after trauma or severe infections).
  • Unremitting external and/or middle ear disease Otitis media.
  • Neoplastic diseases of the ear canal or bulla.
  • Failed lateral or vertical resection (TECA as a salvage procedure).
  • Cholesteatoma.

Advantages

Disadvantages

  • Higher degree of complications compared with other surgical procedures of the ear canal.
  • Reduction in hearing capacity, near complete conductive hearing loss after the procedure.
