Incidental finding of dysgeusia relieved by injections of botulinum toxin A.
OBJECTIVE
We report the unique finding of hemifacial spasm and associated dysgeusia that resolved after treatment with botulinum toxin A (BTX-A).


METHODS
Case report.


METHODS
Three years after undergoing resection of an acoustic neuroma and subsequent resolution of postoperative left-sided facial nerve palsy, a 38-year-old woman presented with new onset of facial spasm and dysgeusia.


RESULTS
After three courses of BTX-A injections during a 2-year period, symptoms of both facial spasm and dysgeusia resolved after treatments and returned between treatments.


CONCLUSIONS
These findings, which have not been reported previously in the literature, indicate a potential role for BTX-A in the treatment of surgically associated dysgeusia.
