Facial palsy after pre-operative embolization of glomus tumours is a rare c
omplication. In our case, complete facial palsy occurred within four hours
after embolization with polyvinyl alcohol foam. Three days later, embolizat
ion material was found in the perineural vessels of the facial nerve in its
mastoidal segment. Six months after complete tumour removal. facial decomp
ression with perineural incision, and steroid therapy, facial function reco
vered completely. Ln cases of embolization of both stylomastoid and branche
s of the middle meningeal artery with resorbable material, temporary facial
palsy can occur.
