SUMMARY
1. LMN CN VII palsy; idiopathic or caused by infection, occasionally results in no taste sensation on the anterior 2/3 of tongue, loss of lacrimation, and hyperacusis.
2. Pregeniculate lesions are associated with the loss of taste, salivation, and lacrimation, while more distal lesions spare these functions.
3. Causes: HSV; VZV which present(s) with vesicles involving the TM & EAC (Ramsay Hunt syndrome); Lyme disease; HIV.
4. Know that if the palsy is preceded by a period of facial twitching, the risk of tumor is higher: urgent imaging required.
5. Patients who begin to improve within 3 weeks will commonly recover completely.
6. A week of prednisone shortens the course and improves function if started within 7 days of clinical onset
