Can FaceTite without liposuction cause Neuropraxia?

Neuropraxia is a first degree nerve injury that interrupts the electrical function of a nerve but does not result in physical disruption of the axon or nerve "tube".  This is a self-limited injury and typically results in temporary weakness when a motor nerve is involved.  Recovery gradually returns over a variable period ranging from a few weeks to several months depending on the degree and location of the nerve injury.  FaceTite can potentially cause injury to a branch of the facial nerve known as the marginal mandibular nerve.  This nerve runs along the lower border of the mandible and signals muscles that pull the lower lip and corner of the mouth down (depressor anguli oris, depressor labii inferiorus) as well as providing tone and tension to the lower lip.  The FaceTite procedure can cause neuropraxia of this nerve either by mechanical trauma ie. the cannula bumping up against the nerve (most likely) or thermal injury (unlikely but not impossible). I understand this can be frustrating but I would encourage you to "hang in there" as the weakness will very very likely improve.Mario J.

Thank you for your question.  If you had the procedure a few days ago, then chances are that you have nerve injury.  This can happen whether or not you had liposuction with your FaceTite procedure.  The vast majority of times, this resolves with time as the nerve recovers.  Depending on the degree of nerve injury, it can take days to months.  I would let your plastic surgeon know what you are experiencing so they can follow along and provide more guidance.  Occasionally, Botox can be used on the other side to help improve symmetry as nerve injury resolves.

Fortunately I have not seen this complication from facetite.  Neuropraxia is a well known complication from any facial surgical procedure and can occur from Facetite.  The nerve injury is either from direct trauma or from heat generated by  the devise.  As Facetite does not involve any cutting of tissue a nerve branch cannot be divided and therefore has a very good chance of full recovery.
