title: [Study of surgical techniques of divided nevus of eyelids].
abstract: OBJECTIVE
  To investigate the surgical techniques of divided nevus of the eyelids with different locations and sizes.
  
  
  METHODS
  Retrospective observational case series. Thirty cases (30 eyes) of divided nevus of the eyelids in Zhongshan Ophthalmic Center from July 1997 to November 2006 were retrospectively reviewed. There were three different surgical methods. Excision of the nevus and direct suture after excision in 3 cases. Excision of the nevus and free skin graft transplantation in 5 cases. Excision of the nevus and transfer of skin flap, which included a two stages reconstruction, was performed in 22 cases. The upper or lower eyelid was treated first and another eyelid was treated after three months. Lacrimal punctum and lacrimal canaliculus were excised if they were involved in 8 cases among 22 cases.
  
  
  RESULTS
  The mean follow-up time was 60 months (ranging from 2 years to 11 years). Only one case recurred after two years during follow-up and was excised after five years. Pathologic examination indicated malignant transformation. Excision with histopathological control was performed and the nevus did not recur during follow-up time. Recurrence or malignant transformation did not occur in other cases. Aesthetical results of skin flap transplantation were better than skin graft transplantation.
  
  
  CONCLUSIONS
  The results of two stages reconstruction and transfer of skin flap after excision of the divided nevus are better than free skin graft transplantation. Close observation is required after excision of the divided nevus for early detection of malignant transformation.
