Incidental finding of dysgeusia relieved by injections of botulinum toxin A.

AbstractOBJECTIVE:
We report the unique finding of hemifacial spasm and associated dysgeusia that resolved after treatment with botulinum toxin A (BTX-A).
STUDY DESIGN:
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.
