Acoustic neuroma. A tumour in the cerebellopontine angle can be removed using ENT access.
The complicated medical term acoustic neuroma describes a tumour that develops on the cerebellopontine angle. The cerebellopontine angle is an anatomical niche located halfway between the brainstem and the cerebellum. Even though this is an anatomical niche: the cerebellopontine angle is very important, because several important functional structures including the nervus trigeminus, the nervus facialis and large arteries run across it.
As this type of tumour arises from a specific type of cell, the Schwann cells, it is also known as the vestibular schwannoma. These tumours, depending on their size and precise location and spread, can also affect the ear canal and the internal structures of the ear. Therefore, in many cases, it makes sense to remove them using an ENT access method. Fundamentally, it should always be checked beforehand whether the tumour is growing and whether treatment is necessary. For many patients non-surgical treatment will be a consideration and possibly the preferred treatment option.
