Discussion-Cervico-Mental Angle Suspensory Ligament: The Keystone to Understand the Cervico-Mental Angle and the Aging Process of the Neck.

This is a commentary and discussion in response to a cadaveric study entitled, "Cervico-mental angle suspensory ligament: The keystone to understand the cervico-mental angle and the aging process of the neck." While highlighting the cervico-mental angle suspensory ligament has the potential to give rise to new surgical technique in neck rejuvenation surgery, the authors caution readers of the study's major limitation. Without well-documented results aligning with aesthetic ideals or reports of the safety and longevity of the procedure, it seems too early to consider this ligament the keystone to understand the aging neck. An actual surgical technique must be described and further clinical studies need to be performed before this ligament can be included in the armamentarium of neck rejuvenation surgery. As the goal of surgery should be a natural result that restores aesthetic ideals of the youthful neck, regardless of the significance that this ligament will carry, its application should be tailored to the patient to avoid overly aggressive treatment.
