The aesthetic aspects of the chin necessitate its evaluation in the context of the nose, mouth, and, to a lesser extent, the neck. Functional consideration must be given to the dental occlusion and the perioral muscular sphincter, and planning should acknowledge the sociologic implications of a strong versus a weak chin. After thorough skeletal and soft-tissue examination, the appropriate type of surgical intervention can be selected. Among the various procedures, chin implant remains the most commonly used, but the osteotomy offers the greatest flexibility, reliability, and potential for significant modification of chin form.
