Summary

An anterior neopharyngeal pseudodiverticulum, a rare pouch after total laryngectomy, frequently causes swallowing difficulties (dysphagia). Endoscopic CO2-laser treatment effectively resolves symptoms in most patients.

Area of Science:

  • Otolaryngology
  • Surgical Oncology
  • Gastroenterology

Context:

  • Anterior neopharyngeal pseudodiverticulum is a rare condition following total laryngectomy.
  • It presents as a mucosal pouch between the tongue and hypopharynx, often due to a posterior tissue band.
  • This study investigates its incidence, symptoms, and treatment in post-laryngectomy patients.

Purpose:

  • To examine the incidence, symptoms, and etiologic factors of anterior neopharyngeal pseudodiverticulum.
  • To evaluate the effectiveness of endoscopic CO2-laser treatment for dysphagia caused by this condition.

Summary:

  • Eleven of twenty post-laryngectomy patients developed an anterior neopharyngeal pseudodiverticulum.
  • Nine of these patients experienced dysphagia, with no correlation to radiotherapy or other complications.
  • Endoscopic dissection of the posterior tissue band using a CO2-laser provided complete symptom relief in 8 out of 9 patients.

Impact:

  • Anterior neopharyngeal pseudodiverticulum is a significant, often overlooked, cause of post-laryngectomy dysphagia.
  • Clinical and radiological diagnosis is straightforward.
  • Endoscopic CO2-laser treatment offers a simple and highly effective therapeutic solution.
