title: Free flap reconstruction of the head and neck: analysis of 241 cases.
abstract: OBJECTIVE
  We undertook this study of free flap reconstruction of the head and neck to stratify patients and procedures, to determine how donor site preference changed over time, to assess medical and surgical outcomes, and to identify variables associated with complications.
  
  
  METHODS
  We analyzed computerized medical records from 236 patients who underwent a total of 241 reconstructions at a tertiary academic medical center in St. Louis between 1989 and 1998. We created a more detailed retrospective database of 141 of those patients by using 48 perioperative variables and 7 adverse outcome measures. Multivariate statistical models were used to analyze associations between variables and outcomes.
  
  
  RESULTS
  The fibula became the preferred donor site for mandibular reconstruction, and the radial forearm became the preferred donor site for pharyngoesophageal reconstruction. For the 241 procedures, the mortality rate was 2.1%, the median length of stay was 11 days, and the flap survival rate was 95%. Administration of more than 7 L of crystalloid during surgery and age over 55 were associated with major medical complications. Blood transfusion, prognostic comorbidity, and number of surgeons correlated with length of stay. Cigarette smoking and receipt of more than 7 L of crystalloid during surgery were associated with overall flap complications, and weight loss of more than 10% before surgery, more than one operating surgeon, and cigarette smoking were associated with major flap complications.
  
  
  CONCLUSIONS
  Risk to patients and transferred tissue is low in free flap head and neck reconstruction. Age, smoking history, and weight loss should be considered during patient selection. Fluid balance should be considered during and after surgery. Division of labor for patient care should be carefully delineated among surgeons in a teaching setting.
