title: [Paranasal sinuses mucoceles. Our experience in 72 patients].
abstract: BACKGROUND
  Traditional treatment for paranasal sinuses mucoceles recommended total removal through external approaches. Since the 90s, endoscopic marsupialization has been proposed as optimal surgical treatment. We present our experience in the treatment of this pathology.
  
  
  METHODS
  A retrospective review of 72 patients treated for paranasal sinuses mucoceles between 1980 and 2006 in our ENT department was performed. We describe clinical features, surgical approaches employed and recurrence of disease.
  
  
  RESULTS
  The sample was composed of 72 patients with average follow-up period of 44 months (range 13-214 months). A total of 81 mucoceles were presented, with 44% affecting the frontal sinus or frontoethmoidal cells, followed in frequency by maxillary sinus mucoceles (35%). Twenty-nine percent of the patients did not present predisposing factors; 31% of patients had a history of nasal polyposis, 35% had undergone previous sinus surgery and 14% suffered previous facial fractures; 48 mucoceles patients were treated endoscopically and 33 were treated with external or combined approaches. Recurrence was found in 7 patients, 2 in the endoscopic surgery group and 5 in the external/combined surgery group.
  
  
  CONCLUSIONS
  Endoscopic marsupialization is a safe approach with a low rate of recurrence. The endoscopic approach may be unsuitable for frontal lateral sinus mucoceles or those with significant bone blockage.
