title: [Anterior craniofacial resection: oncologic outcome and complications in a series of 111 cases].
abstract: BACKGROUND
  Anterior craniofacial resection is a standardized procedure for the treatment of ethmoid and frontal orbital tumors with intracranial invasion.
  
  
  METHODS
  A retrospective review of 111 patients with sinonasal tumors involving the anterior skull base who underwent combined craniofacial surgery.
  
  
  RESULTS
  The most frequent pathological entity was adenocarcinoma (54 cases) and other epithelial tumors (29 cases). Five year actuarial survival according to the Kaplan-Meier method was 40%. Survival was affected by the histology of the tumor, brain involvement, and deep soft tissue involvement of the orbit. The UICC staging system did not show statistical prognostic significance. Complications occurred in 39 (35.1%) patients, resulting in 4 (3.6%) postoperative deaths. Major complications included cerebrospinal fluid leak in 18 patients, meningitis in 10, infection in 9, stroke in 4, and pneumocephalus in 4. The extent of the craniofacial resection was the most important factor associated with major complications.
  
  
  CONCLUSIONS
  Despite the advanced stage of most of the patients, anterior craniofacial resection succeeded in terms of an acceptable survival rate. Nevertheless, significant complications were observed although in most patients were not life-threatening and had no negative impact on the quality of life.
