Is Gamma Knife Surgery effective for intracanalicular vestibular schwannomas?

Vestibular schwannomas (VSs) are rare, occurring in approximately five per 100,000 adults a year. In circa 8% of cases, the VS is contained within the internal auditory canal, i.e. intracanalicular (iVS). Although radiosurgery is a recognised treatment modality for VSs,...

Global incidence of sporadic vestibular schwannoma

The incidence rate of sporadic vestibular schwannoma (VS) has commonly been quoted as one in 100,000. However, since the advent of screening for asymmetrical hearing loss and increased availability of modern MRI scanning, more recent studies have shown the incidence...

Impaired vestibulo-ocular reflex (VOR) gain correlates with hearing loss in vestibular schwannoma

The lack of correlation between the size of vestibular schwannoma (VS) and degree of hearing loss and vestibular function tests is well known. In this retrospective study, the focus was on the correlation between VOR gain of semicircular canal function,...

Preserving hearing in NF2 patients

Neurofibromatosis type 2 (NF2) is known to result in bilateral hearing loss, even when there is no significant tumour growth. The cause is postulated to be multifactorial: stretching and compression of the cochlear nerve by the tumour, impairment of labyrinthine...
