title: [Complications of scalp coronal incision: analysis, prevention, and treatment].
abstract: OBJECTIVE
  The aim of this study was to analyze the complications of coronal incision and investigate the methods of prevention.
  
  
  METHODS
  The retrospective analysis was based on 149 cases, who have had operations since 1997 for congenital craniofacial malformation, second deformation of craniomaxillofacial trauma, maxillofacial tumor or cosmetic purposes.
  
  
  RESULTS
  Of them, there were injury of unilateral frontal branch of the facial nerve in 3 cases, subcutaneous hematoma in 9 cases, alopecia in 12 cases, incision scar in 14 cases, obvious strip scar in 2 cases, pains, numbness and paraesthesia in 23 cases, ptosis of facial soft tissue in 8 cases and infection in 4 cases.
  
  
  CONCLUSIONS
  The coronal incision has the merits of distinct exposure, hidden incision scar, but its complications can not be neglected. During the operation, care should be taken to anatomical layers, protecting the blood vessel and nerve bundle in order to reduce complications.
