Summary

Ectopic adenoid tissue in the choanae causes long-lasting nasal stenosis unresponsive to standard treatments. Transnasal removal via forceps offers a successful treatment for this rare condition, improving nasal airway obstruction.

Area of Science:

  • Otolaryngology
  • Rhinology
  • Pediatric Surgery

Background:

  • Nasal stenosis can be a debilitating condition, often requiring multiple treatments.
  • Ectopic adenoid tissue in the choanae is an underdiagnosed cause of persistent nasal obstruction.

Purpose of the Study:

  • To identify and describe ectopic adenoid tissue in the choanae as a cause of nasal stenosis.
  • To evaluate the efficacy of transnasal forceps removal for this condition.

Main Methods:

  • Diagnosis was established using anterior rhinoscopy with a flexible rhinopharyngo-laryngoscope.
  • Treatment involved transnasal removal of ectopic adenoid tissue using forceps.
  • A series of 19 patients with persistent nasal stenosis were studied.

Main Results:

  • Ectopic adenoid tissue was successfully removed transnasally in all 19 patients.
  • All patients experienced relief from long-lasting nasal stenosis symptoms.
  • This condition is estimated to affect approximately 2% of patients with adenoid-related symptoms.

Conclusions:

  • Ectopic choanal adenoid tissue is a treatable cause of chronic nasal stenosis.
  • Transnasal endoscopic examination is crucial for diagnosing this condition.
  • Prompt diagnosis and treatment can resolve prolonged nasal airway obstruction.
