My preferred treatment for excess fat in the neck region involves the use of the Precision Tx laser combined with liposuction. This allows for tightening of the skin in addition to fat removal. This can be performed through a small incision in the chin crease on the neck and two small incisions behind each ear.The round face in women is sometimes attributable to hypertrophy of the masseter (enlargement of the jaw muscles). This contributes to fullness at the jawline. Botox can be used to weaken this muscle and create a more oval shape to the lower face.Many women complain of fullness in the cheeks, and some plastic surgeons will remove fat from the cheek (buccal) fat pad. I do not perform this procedure, and I caution against removing fat from the face. A round face is a youthful face; a face without fat is an aged face. Over time, the excess fat in the cheeks will keep you looking younger and younger!
Thanks for your question. Liposuction of he neck, underneath the chin and mandible does not change the basic structure of your face. If you have round cheeks you will have round cheeks despite lipo of the chin. However, it will streamline your neck giving a more appealing profile and front view. Unfortunately you did not post profile photos and so the assessment is incomplete. Consult with a plastic surgeon certified by the American Board of Plastic Surgery. Good luck
