title: [Laser coagulation in the endoscopic management of fourth branchial pouch sinus].
abstract: OBJECTIVE
  To describe a new method of treatment of the fourth branchial pouch sinuses by laser endoscopic coagulation of the fistula.
  
  
  METHODS
  Retrospective study of two children aged 3 and 12 years with fourth branchial pouch sinuses. Both children presented recurrent cervical abscesses. The diagnosis was established on results of ultrasound, barium study, CT scan and pharyngoscopy. After recovering from infection, the definitive treatment was a laser diode cauterization of the fistulous route and its pharyngeal opening.
  
  
  RESULTS
  Outcome was rapidly favorable in both children without complications or recurrence.
  
  
  CONCLUSIONS
  These two cases and other reports in the literature confirm the role of endoscopic management for the treatment of the fourth branchial pouch sinus. Laser treatment is especially useful because of its convenience, its harmlessness and its reliability.
  
  
  CONCLUSIONS
  Fourth branchial pouch sinuses are rare. Surgery, which can be difficult and not without risks, is the generally accepted treatment. This new laser method combines ease of treatment and efficacy.
