title: [Clinical evaluation of local application of Merogel after endoscopic sinus surgery].
abstract: OBJECTIVE
  To study the auxo-action of Merogel (hyaluronic acid) for operative cavity epithelialization after endoscopic sinus surgery (ESS).
  
  
  METHODS
  Sixteen patients (32 sides) were observed, in which all sinuses(maxillary, frontal, ethmoid and sphenoid) were operated on by ESS. For the purpose of control study, the left nasal side was used as Merogel group, and right side contrast group. The patients were followed-up for 12 weeks.
  
  
  RESULTS
  In Merogel group, the curative rate was 93.75%, improvement rate 6.25%, and average time of epithelialization was 3.4 weeks. In contrast group, the curative rate was 87.50%, improvement rate 12.50%, and average time of epithelialization was 8.3 weeks. It was distinct that in Merogel group, the epithelialization time was shorter than that in contrast group.
  
  
  CONCLUSIONS
  Merogel has auxo-action for operative cavity epithelialization after ESS.
