Changing patterns of hospital length of stay after orthognathic surgery.

Purpose: The purpose of this study was to estimate the hospital length of stay (LOS) and identify factors associated with LOS in orthognathic surgery patients.

Materials And Methods: Using a retrospective cohort study design, we enrolled a sample composed of patients who underwent orthognathic surgery at Massachusetts General Hospital between January 1994 and July 2006. The primary predictor variables were fixation type (rigid/nonrigid), anesthesia technique (hypotensive/normotensive), and perioperative steroid use (yes/no).
