title: [Nasal sinus mucoceles after sinus surgery or trauma].
abstract: OBJECTIVE
  To analyse the causes of nasal sinus mucoceles after sinus surgery or trauma and explore operative therapy and methods of avoiding mucoceles recurrence.
  
  
  METHODS
  Retrospective analysis were made in 22 cases of nasal sinus mucoceles after sinus surgery or trauma.
  
  
  RESULTS
  All the cases underwent endoscopic mucosectomy. There is one recurrent frontal mucocele in follow-up one year later after surgery and coherency of the lateral nasal cavity with the middle nasal concha in two cases.
  
  
  CONCLUSIONS
  Sinus surgery or trauma can induce nasal sinus mucoceles. So it is necessary to fix the sinus fracture site and replace the mucosa as possible, keep the the middle nasal concha stability and healthy sinus mucosa in endoscopic surgery,and take long term follow-up for reducing mucoceles recurrence.
