While standard or laser Assisted liposuction is safe in the neck area, great care must be exercised when attempting liposuction in the jowl area.
The Marginal Mandibular Branch of the Facial Nerve runs near the surface of the skin unprotected by the SMAS or Platysma Muscle just below the corner of the mouth in the Pre-Jowl Sulchus just in front of the jowl.
If the Margiunal Mandibular Nerve is injured muscles which hold the corner of the mouth in position are paralyzed creating a very visible and catastrophic deformity of the mouth. The smile can be grossly distorted following this nerve injury and the deformity is usually permanent.
Board Certified Plastic Surgeons are trained to understand the location of this nerve and avoid it during facelift procedures.
Liposuction in the jowl area subjects this nerve to risk of injury.
Unfortunately many doctors who are attempting facial liposuction are not board certified plastic surgeons and many are unaware of facial nerve anatomy and the risk of Marginal Mandibular Nerve Injury.
If you are considering liposuction in the Jowl area be certain to see a Board Certified Plastic Surgeon and ask him/her what streps they will take to avoid injury to the Marginal Mandibular Nerve.
Detailed anatomic drawings of this nerve are available in my Book Facial Danger Zones.
