title: [Application of mucoperiosteal flap of nasal septum to repair defect of fossa orbitalis, hard palate and the anterior skull base].
abstract: OBJECTIVE
  To investigate the neoplasia of fossa orbitalis, hard palate and the anterior skull base defect by making use of mucoperiosteal flap of nasal septum.
  
  
  METHODS
  A retrospective study was reviewed in 12 patients with tumors in nasal cavity and nasal sinuses. According to tumor character and range, by partial or total maxillectomy and ethmoidectomy, fossa orbitalis, hard palate and the anterior skull base defects were repaired synchronously on the heels of resection of the tumors which damaged fossa orbitalis, hard palate and the anterior skull base.
  
  
  RESULTS
  Among the 12 patients there were 5 patients with the destructions on ethmoidal horizontal plate, 2 patients with the destructions on hanging wall of ethmoid, 1 patient with the destruction on hanging wall of fossa orbitalis, 1 patient with the destruction on medial wall of fossa orbitalis and on floor of orbit respectively, 2 patients with the destructions on hard palate and all the destructions were repaired following detection synchronously. There were no complications of surgical death, cerebrospinal fluid leaks, encephalomeningocele.
  
  
  CONCLUSIONS
  During the operation of tumor in nasal cavity and/or nasal sinuses when defect of fossa orbitalis, hard palate and anterior skull base were found and the defects need repair, we can take advantages of mucoperiosteal flap of nasal septum to perform the transplantation of mucoperiosteal flap in order to avoid forming local defect.
