neurapraxia
Pronunciation: NOOR-ah-prak-see-ah
Temporary nerve dysfunction causing numbness or weakness without structural damage, often occurring after facial surgery.
Full Definition
Neurapraxia is the mildest form of peripheral nerve injury characterized by temporary dysfunction due to local ischemia or compression without structural damage to the nerve fiber. In cosmetic surgery, neurapraxia commonly affects the marginal mandibular branch of the facial nerve during facelifts or neck procedures, causing temporary weakness of the lower lip. The condition is reversible, with function typically returning within days to months as the nerve recovers. Unlike more severe nerve injuries (axonotmesis or neurotmesis), neurapraxia involves only disruption of nerve conduction without damage to the nerve structure itself. Recovery is generally complete without surgical intervention.
Usage
Usage note: Distinguish from more severe nerve injuries; emphasize temporary nature in patient communications.
