Objective To exploring a new minimally invasive method for the removal of moderate and severe glabellar frown lines. Method The corrugator supercilii muscles were subjected to blunt cutting and vacuum suction by using a self-made modified liposuction needle,and the obtained muscle particles were backfilled subcutaneously into the depression area between eyebrows to expand the wrinkles. Results Seventeen cases were followed up for six to twelve months after the operation.The glabellar wrinkles disappeared or became flatter in all patients. Conclusion The minimally invasive corrugator resection and backfill by using self-made modified liposuction needle can effectively remove the glabellar frown lines without forming scar.
