(b) Contrast showing an enhancing lesion in the internal auditory meatus involving the 7th-8th nerve complex most likely acoustic neuroma (red circle).
This correlates well with the study by Cosnard G et al 1992[7] who reported that acoustic neuromas represent 75% of all tumours of the cerebellopontine angle.
Compared with men in manual roles, professional and managerial roles (intermediate and high non-manual jobs) were associated with a 20% heightened risk of glioma and a 50% heightened risk of acoustic neuroma.
Their topics include the surgical anatomy of the cerebellopontine angle, nerve monitoring for cerebellopontine angle surgery, vestibular neurotomy by minimally invasive retrosigmoid approach, hearing preservation surgery for acoustic neuroma, and auditory brainstem implants.
