The times varies depending on several factors including the type (e.g., deep plane versus plication) and QUALITY of the facelift being performed, the patient's anatomy, aesthetic goals, previous surgeries of the patient, and if other procedures are being performed at the same time. Also, the time in the operating room is different than the surgical time of the procedure, whereas the former includes positioning the patient, induction of anesthesia, prepping the patient, post-operative facial dressing, emergence from anesthesia and initial recovery before exiting the operating room. Anything less than 4 hours is typically too short a time.The attached link provides more information.I hope this helps.
