As a guy, where can I hide scars from a neck tightening surgery?

While a direct neck lift is a minimally invasive and effective option, I would not normally recommend it because it will leave a visible scar on the neck. Instead, I would most likely recommend a regular neck lift or lower face lift. There are more incisions, but the scarring is much less visible and the results are dramatic. When performing a face or neck lift, I use the most minimally invasive techniques and prioritize patient comfort and satisfaction while still performing the most thorough and effective surgery possible. I always tighten the deeper underlying tissues as well as redraping the skin to create long-lasting results, and patients find that they look much more youthful with practically invisible scars.
I hope this helps!

Incisions in male patients heal wonderfully when performed correctly. I have done plenty of face and neck procedures (some on actors) and the incisions have healed fantastic. The incisions line in the natural creases around the ears. I would review your surgeons before and after pictures, especially of his male patients, and have him show on you how the incisions would be performed. 

Thank you for your question. With the Laser Assisted Weekend Necklift, there is only a small incision that is made under the chin and a tiny incision behind each of the ears. The procedure also avoids the extensive incisions that are made around the hairline and ears during a conventional facelift. I suggest that you move forward and consult with a board certified facial plastic surgeon.
Best wishes,

  The face lift Incisions are well camouflaged in front and behind the ears for a male facelift procedure.  A lower face and neck lift is performed to tighten loose facial and neck skin, tighten loose facial and neck muscles, remove fatty deposits in the neck, a platysma plasty and lift the jowls.  For more information and many  before and after examples of male facelifts, please see the link and the video below

 Hi, I have performed facelifts and neck lifts for over 30 years and have performed many minimally, invasive type facelifts.  Non smiling photos of your face from the front and side would help in the evaluation.  When looking at the profile, degree of chin projection as well as excess fat and skin should be evaluated.
 I have performed many Chin Augmentations using chin implants for over 30 years.  When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy and the lower face look short that de-emphasizes the lips and allows early formation of a double chin.  Chin augmentation using a chin implant will add projection to the chin creating harmony and balance to the lower face. 
 I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty.  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  In my opinion, you are a good candidate for chin implant surgery.
 Liposuction can reduce excess fat and skin can be reduced using two options.  The first reduces some but not all of the excess, using a curved incision under the chin.  This is the least invasive and has the smallest scar which can be hidden under the chin.  The next option requires a "full neck lift" which is performed using a curved incision around the front (explained later) of the ear that continues in the crease behind the ear and then 3 inches into the posterior hairline.  The tissue is dissected from that point all the way across the entire neck to the same position on the other side of the head in a dissection that is as long vertically as the entire neck.  The Platysma muscles are tightened using a curved incision under the chin and each side is pulled upward and back again being tightened at a line behind each ear (under the tissues).  Since the skin flap pull is up and back, this will pick up any tissue laxity along the jaw line or "jowls" which must be dissected and flattened out using a lower facelift (incision around the front of the ears).  If this isn't done, pleats of excess skin will appear below each ear.
This is an extensive surgery taking 4 1/2 to 5 hours with large incisions, possible hair loss and months of recovery.  In my experience, most men opt not to have the telltale signs of this type of surgery since they can't cover them with long hair.
Hope this helps.

I typically place a small incision under the chin and in the crease behind the the ear which may be extended into the hair. Even in a man the short hair the resulting scars are not a cosmetic problem. Consult with a facial rejuvenation surgeon to discuss your options, explain risks, and establish reasonable expectations.
