title: Lessons from 28 cases of reconstruction by lenticular island pedicle flap at a single institution.
abstract: BACKGROUND
  Lenticular island pedicle flap (LIPF) has been reported to be one of the most useful techniques for reconstructing middle cheek skin defects. LIPF may have been used all over the world on a daily basis; however, no reports have examined a large number of LIPF cases at a single institution.
  
  
  METHODS
  A total of 28 cases of reconstruction by LIPF at the Hokkaido University Hospital from 2005 to 2013 were analysed. We examined the tumour type, location, area of defect and presence/absence of antithrombotic treatment and complications, including transient circulatory impairment, damage to facial nerves and eyelid ectropion.
  
  
  RESULTS
  We found that nine patients had transiently impaired circulation. This complication was statistically more frequent in the patients without antithrombotic treatment than in the patients with antithrombotic treatment (0/8 vs. 10/20, P = 0.0292; Fisher's exact test).
  
  
  CONCLUSIONS
  We revelled that LIPF have been safely performed even under antithrombotic treatment, so, when patients are taking antithrombotic agents, we should choose LIPF rather than conventional flap including cheek flap, island pedicle flap and so on.
