Generally speaking, combination surgical procedures are done routinely. However, you are wise in being concerned about the safety of combination surgery; risks/possible complications do increase with increased length of surgery… In my practice, I would recommend that you not undergo all these procedures at the same time. It is best to evaluate each patient's suitability for combination surgery on an individualized basis. During this consultation process, after a complete history and physical, the SAFETY of combining these surgical procedures becomes of paramount importance. Plastic surgeon, anesthesia provider, duration of surgery, surgery facility all important considerations. Your best bet: choose your plastic surgeon very carefully; everything else including good judgment/advice/planning, anesthesia provider and safe surgery facility will follow. Best wishes.
