Hi, based upon the attached photos, you are correct that your face is flat and also round. Women's faces appear the most attractive when the face is heart-shaped. The photos reveal very flat cheeks anteriorly (in the front) with excess fatty tissue in front and below the cheeks as well as lax facial tissues and jowls. The chin is weak and there is excess fat and skin below the chin. IMHO the following procedures would make your face more heart-shaped, feminine and naturally attractive. Pushing the mandible back will only accentuate the weak lower face and would not be aesthetically pleasing.Cheek augmentation with a dermal filler (I prefer Perlane) or using cheek implants for a more permanent enhancement. Micro-liposuction of the excess fat to further shape and define the cheeks. This will shape the cheeks and feminize the entire face.Chin augmentation with a chin implant to add harmony and balance to the lower face.Facelift to remove excess loose skin.If you have "jowls" this is sagging facial tissues and an indication for some form of a facelift, not Cheek Augmentation. I have performed many Cheek Augmentations over the past 25 years and the notion that Cheek Implants or dermal fillers to the cheeks will lift tissues is an urban myth. Filler to the cheeks or cheek implants will not lift up the jowls. The underlying SMAS layer, of the face, must be dissected, lifted, trimmed and re-sutured (not merely folded or suspended with threads or sutures that will not last). The excess skin is then removed and the facelift incisions closed.My most popular facelift is the minimally invasive, short incision facelift that has all the benefits of more invasive facelifts (traditional, mid-face and subperiosteal facelifts) but with these added benefits:very small incisionsminimal tissue dissection = less bruising and swelling = rapid recoverycan be performed in 90 minutes or less, with or without general anesthesiano incisions within the hair = no hair lossexcess fat can be removedexcess skin removedcheeks, chin and jaw line can be augmented with dermal fillers (I prefer Perlane) or facial implantsmost patients fly back home to parts all over the world in as little as 3 days post-opHope this helps.
