title: Comparison of polyvinyl alcohol coated nasal packing with non-absorbable nasal packing.
abstract: BACKGROUND
  A number of different nasal packing materials are available for prevention of nasal bleeding after endoscopic sinus surgery. Polyvinyl alcohol (PVA) coated nasal packing is an expandable packing for use in rhinological surgery. This innovative surf- ace treatment helps to reduce the possibility of adherence to tissue and of blood clotting within the sponge. The present study investigated the effects of PVA coated packing and non-absorbable packing with respect to pain, healing site and postoperative bleeding following endoscopic sinus surgery.
  
  
  METHODS
  Patients between 18-80 years of age undergoing sinus surgery were enrolled. Each patient`s ethmoid cavities were randomised to receive PVA coated packing material or the standard non-absorbable sinus packs. The remaining nasal packing material was removed on the 2nd day in the clinic. We determined visual analog scale score, bleeding time and wound healing status. A single rhinologist graded postoperative endoscopic appearance. Length of follow-up was 3 months.
  
  
  RESULTS
  Thirty three patients were recruited. There was a significant difference in the bleeding time between the two groups, but pain and wound healing were not significantly different between the two groups.
  
  
  CONCLUSIONS
  PVA-coated nasal packing presents comparable characteristics with traditional nasal packing.
