I've been doing facelifts for over 20 years now and have used a head strap on patients for about one year during that time -- way at the beginning of my career. The head strap was annoying, irritating, rubbed areas that were sensitive or delicate and perhaps reduced blood and lymphatic flow from areas that were healing, therefore interfering with the normal healing process. However, the most important point is that I saw absolutely no advantage to wearing one, in terms of healing, swelling or results -- and my results are good enough to be considered some of the best results in the country, as determined by NewBeauty magazine. So I'm not sure what benefit other surgeons find in using them.Regardless of my experience and opinion, your surgeon apparently believes there is benefit, so I would discuss this with him/her and follow their directions.
