Dr Ngo performs facial cosmetic surgery. In particular, his frequent dealing with the facial skeleton drives his interest in bone-reshaping work such as jaw or cheek contouring and chin reduction or advancement (genioplasty). Facial bones form the foundation of the face on which drapes the soft tissue envelope. While much of facial cosmetic surgery focuses on the soft tissue element such as face lift, brow lift etc., changing the soft tissue alone without changing the underlying hard skeleton has limitations in terms of how much the appearance can be enhanced. Shaping of the underlying skeletal structures can at times bring about dramatic facial feature changes that cannot occur through soft tissue manipulation.
