Insights

Endoscopic diathermy effectively treats congenital third and fourth branchial pouch sinuses (recurrent neck abscesses) by closing the internal opening. This minimally invasive approach offers a safe and successful alternative or adjunct to traditional surgery.

Area of Science:

  • Otolaryngology
  • Pediatric Surgery
  • Endoscopic Surgery

Background:

  • Congenital third and fourth branchial pouch sinuses are rare causes of recurrent neck abscesses in children.
  • These sinuses feature an internal opening within the piriform fossa.
  • Conventional treatment involves complete surgical excision of the sinus tract.

Observation:

  • A retrospective review of four pediatric cases with piriform fossa sinus was conducted.
  • Monopolar diathermy was applied endoscopically to the internal sinus opening.
  • Three patients underwent diathermy for recurrent abscesses post-excision; one had simultaneous excision and diathermy.

Findings:

  • Endoscopic diathermy of the piriform fossa sinus opening resulted in no serious complications.
  • No recurrence was observed during follow-up periods ranging from 9 to 27 months.
  • This technique proved effective in obliterating the internal sinus opening.

Implications:

  • Endoscopic diathermy is a safe and effective management option for piriform fossa sinuses.
  • It can be used as an alternative to or adjunct with external surgical tract excision.
  • This approach offers a minimally invasive solution for recurrent neck abscesses in children.
