Resolution of hemifacial spasm after successful treatment of posterior fossa arteriovenous malformation by gamma knife radiosurgery

There is limited literature about direct gamma knife irradiation of facial nerve for HFS but there are lots of publications about gamma knife treatment of trigeminal neuralgia, which is another cranial nerve hyperactive dysfunction syndrome (HDS). [...]there is one case report about direct gamma kni...

Description
Summary:There is limited literature about direct gamma knife irradiation of facial nerve for HFS but there are lots of publications about gamma knife treatment of trigeminal neuralgia, which is another cranial nerve hyperactive dysfunction syndrome (HDS). [...]there is one case report about direct gamma knife irradiation of VII-VIII nerve bundle for idiopathic HFS in a patient with severe hypoacusia and there are two cases of idiopathic HFS with no auditory problems which were treated with hypofractioned stereotactic radiotherapy, with 15Gy in 5 fractions of 3Gy each, and all of three patients had improvement of their symptoms with no auditory complications [11]. [...]in light of these preliminary findings about gamma knife irradiation of facial nerve for HFS, low dose radiation also may help improvement of symptoms in our patient.
