Chin And Malar Aesthetics
What is chin aesthetic (mentoplasty – chin augmentation – chin reduction)?
When doing an operation is aesthetic surgery, first it is important to know what the normal appearance is. In the procedures directed to chin, first, it should be determined that the chin is whether big/small or protruded/retruded. As a simple method to understand; an imaginary line passing through the lips ahould also pass through the tip of the chin in men, but the chin of the women should be 2-3 mm behind this line. Besides, measurements related to the length of the face are helpful in determining whether the chin is long or short. Face is divided into three regions horizontally; hair line – eyebrow, eyebrow – nose tip, nose tip – chin tip. The distance between the nose tip and the chin tip is also divided into three; nose tip to upper lip ahould be 1/3, and lower lip to chin tip should be 2/3 of this distance. Besides, the angle between the chin and the neck should be around 90 degrees. Another thing to be determined is the relation between the upper and lower chins and the contact of the teeth.
The purpose is to restore these ratios. To decide what to do is the most important parameter to affect the result, and it is directly related with the aesthetic vision of the surgeon.
Is it going to be a scar in chin aesthetic?
In chin aesthetic, as the surgical interventions are generally made through the oral cavity, there won’t be any scars on the visible areas. Synthetic materials as well as the patient’s own tissues can be used to augment small chins. In the wide and/or protruded chins, procedures directed to the bone are essential.
CHIN IMPLANTS
A long sweeping elegant jawline is a most desirable feature in an attractive face and neck Retrognathia, manifested by bony mandibular deficiency and/or loss of muscular skin pad posture, creates facial disharmony and proportion imbalance. Inadequate chin projection is commonly encountered in patients seeking aesthetic facial surgery. Although chin augmentation may be performed as an isolated procedure, it is frequently performed as an adjunct to rhinoplasty or rhytidectomy. Submental lipectomy associated with chin augmentation adds a further refinement to the mandibulocervical definition.
Malocclusion and significant facial skeletal abnormalities are of course not corrected by chin augmentation alone. Patients with major mandibular deficiencies and asymmetries are best treated by orthognathic and orthodontic correction.
In the rhinoplasty patient, augmentation of the chin brings the lower third of the face into improved alignment and harmony with the middle third. The degree of apparent nasal projection is often dramatically changed in appearance by relative changes in chin projection.
The rhytidectomy patient, as a consequence of aging, commonly exhibits poor chin projection associated with an obtuse cervicomandibular angle. Conservative augmentation with a chin implant establishes better projection and increased differentiation of the mandibular horizontal and cervical vertical planes. The implant may also serve to augment the ptotic chin softtissue structures frequently found in the aging chin; significant chin pad sagging, however, requires cephalic repositioning of the ptotic muscle pad to correct an inferior malposition of these tissues.
Chin implants can be placed through an intraoral or a small external incision. External incision is placed under the chin and is not visible. Silicon and polyethylene (porex) implants are available in market for chin augmentation. We prefer polyethylene implants in majority of our applications.
MALAR IMPLANTS
Augmentation of cheek bones plays a significant role in facial contouring. The patients who present with a generally flat appearance of the midface will benefit from malar augmentation. The results of midface augmentation in the appropiate patient has been very gratifying. It can produce a nice contour to a flat or poorly defined face. Silicon or polyethylene (porex) implants can be used for augmentation of cheek bones. We prefer polyethylene implants in most of our cases. Our preffered way of implantation through the intraoral way. Malar augmentation is usually combined with face lift procedures.
