Chin skin may become loose due to aging, obesity, bone reduction, liquid silicone injection, or skin elasticity loss and thinning. Mild cases may result in a round chin that loses its original angle, whereas severe cases may cause the point of the chin to droop and taper down, making it look like a typical long witch’s chin from a lateral perspective. Moreover, patients cannot jerk the chin point when speaking or smiling, showing bilayer skin and other unnatural lines. A local chin lift may be considered to improve the above conditions.
This surgery is a regional lift and is performed by directly making an incision of approximately 3–5 cm at the turning point of the skin at the bottom of the chin. Via the incision, the skin peripheral to the chin and subcutaneous fascial layer are separated. Patients with severe sagging may require suspension suturing at the deeper muscular layer to elevate the chin angle to the normal position. Injection fillers or liquid silicone gel, if any, should also be taken out at the same time to lower the load of the chin skin. Finally, loose skin is excised and the wound is closed. This surgery may also be performed in combination with neck lift to shrink the jaw area via neck skin centralized suturing, which will achieve a better V-shaped face effect.
