An under projected chin is a genetically inherited facial feature, and generally causes patients to have a chin that looks too set-back or not prominent enough. One of the most important components for a beautiful face is to have symmetry, and this is one reason a Houston patient may consider having chin augmentation surgery. This cosmetic procedure is designed to balance the patient's facial features so that she/he has a more proportional face, a stronger jaw line, and a better defined chin. Chin augmentation may require a silastic chin implant, or another form of augmentation depending on the patient's circumstances. Besides cosmetic reasons, chin surgery can also be done for medical purposes because a receding chin can cause obstructive sleep apnea if left uncorrected.
