facial nerve palsy
Also found in: Dictionary, Thesaurus, Encyclopedia.
Bell’s palsyAcute peripheral paralysis of the face due to a herpes simplex immune-mediated condition, often characterised by severe pain arising in the trigeminal nerve, the chief sensory nerve of the face, which arises in cranial nerve VII.
Abrupt onset, drooping mouth, unblinking eye, twisted nose, uneven smile, distorted expressions; paralysis hits maximum in 1 to 14 days; retroauricular pain, facial numbness, epiphora, parageusia, decreased tearing, hyperacusis, hypoesthesia or dysesthesia of cranial nerves (CN V and IX), motor paresis of CN IX and X, papillitis of tongue.
Risk of Bell’s palsy increases with age; age 10 to 19, 2:1 female:male ratio; age 40, 3:2 men:women ratio; pregnant women have 3.3 times increased risk than nonpregnant; DM = 4.5 times increased risk of BP; 10% of patients have positive family Hx of BP.
Tumours or masses, otitis media, sarcoid, Lyme disease, skull fracture, facial injury.
Guillain-Barré syndrome, Melkersson-Rosenthal syndrome, Möbius syndrome, motor neuron disease, myasthenia gravis.
Trauma, Bell’s palsy, stroke, parotid tumours, intracranial tumours.
Microvascular and micro-neurosurgical tissue transfers allow restoration of functional, unconscious, symmetrical facial movements; acyclovir; steroids (uncertain efficacy); artificial tears; neuromuscular retraining—e.g., mirror/visual feedback, biofeedback or electromyography feedback.
60 to 80% recover, especially if incomplete paralysis, and patient is young.

A chronic progressive degenerative disease of the central nervous system that has its onset in middle age. Common symptoms include difficulty walking (with frequent falls), impairments in speech and in swallowing, and an inability to gaze upward.
Saturday night palsy
Paralysis due to prolonged ischemia of the musculospiral nerve incident to compressing an arm against a hard edge. It occurs if the patient has been comatose or in a stupor or has fallen asleep with the arm hanging over the edge of a bed or chair. In some cultures individuals traditionally become intoxicated on Saturday night; while stuporous, they may remain in a position that allows nerve compression.Synonym: musculospiral paralysis; radial paralysis; Saturday night paralysisSunday morning paralysis
