Summary

Chronic otitis externa (COE) is often caused by moisture. A new surgical technique, lateral conchomeatoplasty, effectively treats narrow ear canals unresponsive to traditional therapies, improving patient outcomes.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Infectious Disease

Background:

  • Chronic moisture is a primary cause of chronic otitis externa (COE).
  • Inadequate lubrication and keratin debris retention promote microbial growth in the ear canal.
  • Conventional medical treatments aim to dry and clean the ear canal but may fail in cases with anatomical variations.

Purpose of the Study:

  • To present a novel surgical technique, lateral conchomeatoplasty, for treating chronic otitis externa.
  • To address anatomical variations, specifically narrow external auditory meatus, that impede ventilation and response to conventional therapy.
  • To evaluate the efficacy of lateral conchomeatoplasty in managing refractory COE.

Main Methods:

  • A simple lateral conchomeatoplasty technique is described, designed to correct both conchal cartilage projection and meatal skin circumference.
  • The procedure addresses the combined factors contributing to a narrow external auditory meatus.
  • The technique has been utilized by the author for over two decades.

Main Results:

  • The lateral conchomeatoplasty procedure was performed on 35 ears.
  • All patients who underwent the procedure demonstrated improvement in their condition.
  • A majority of the patients achieved complete resolution of chronic otitis externa symptoms.

Conclusions:

  • Lateral conchomeatoplasty is an effective surgical solution for chronic otitis externa associated with narrow ear canals.
  • This meatoplasty technique uniquely addresses the anatomical issues causing meatal stenosis.
  • The long-term success observed in a significant number of patients supports its clinical utility.
