Chin augmentation with silicone implants has long been considered as a simple and effective
operation to increase chin projection. However, insertion and subsequent removal of silicone chin
implant are not a reversible procedure, as commonly believed. Removal of silicone chin implant is
usually associated with mentalis displacement, chin ptosis, and abnormal contraction of mentalis
muscle, leading to \\\\\\\"bizarre chin configurations\\\\\\\" that are refractory to surgical treatment. I also
experienced a patient who developed bizarre ball-like appearance on her chin pad after the removal
of chin implant because of pain, which was inserted subperiosteally through an intraoral approach 6
months ago. In order to improve the chin deformity and decrease bizarre chin configuration
aggravated by an abnormal overactivity of underlying mentalis muscle, fusiform skin with underlying
soft tissue was excised vertically and chin pad was tightened. Postoperative 2 months photograph
showed improvement of chin disfigurement, and vertical scar was acceptable.
