Auditory neuromas or vestibular nerve sheath tumors are benign tumors with an envelope that originate from the vestibular nerve sheath and are caused by the proliferation of Schwann cells. The most common source has been reported to be the inferior vestibular nerve (up to 91%), with the remainder originating from the superior vestibular nerve and occasionally from the cochlear or facial nerves. Auditory neuromas account for approximately 80% of tumors of the pontocerebellar horn of the cerebellum, followed by meningiomas and epidermoid cysts. Trigeminal nerve sheath tumors are second only to auditory neuromas and account for about 5% of intracranial nerve sheath tumors, with facial nerve sheath tumors in third place. The average growth rate of auditory neuromas ranges from 0.9 to 1.2 mm per year. many retrospective reports on the natural course of auditory neuromas have been published, but long-term prospective data are still lacking. Therefore, the exact natural course of auditory neuroma is unclear. Tumors within the internal auditory canal appear to grow much more slowly than tumors outside the internal auditory canal. However, the tumor needs to be ready for surgical treatment at all times as bleeding, cyst formation, or edema may lead to rapid tumor enlargement. In the early internal auditory canal stage, the tumor grows from the base of the external internal auditory canal towards the inner ear door. This may lead to compression of the cochlear nerve. In the cerebral pool stage, the tumor grows 1 to 50 px from the internal auditory meatus toward the brain pool near the brainstem. usually, the tumor grows spherically within the pontocerebellar horn of the cerebellum. Dural irritation may occur, as well as further compression of the cochlear and vestibular nerves. As the tumor approaches 50 px, it usually contacts the lateral aspect of the brainstem. Further growth of the tumor will inevitably lead to compression or displacement of the brainstem. When the tumor reaches approximately 100px, it tends to extend anteriorly and compress the trigeminal and abducens nerves. Although this is rare, tumors can also extend inferiorly into the jugular foramen resulting in deformation of the posterior group of cerebral nerves. In rare cases, the tumor may compress a blood vessel, leading to venous or arterial infarction. Because of these unique characteristics of auditory neuromas, multiple treatment options exist. For each different patient, the tumor size, location and hearing are different, and each patient needs to be tailored to choose the appropriate treatment modality. Therefore, in a sense, it is important to find the right doctor to provide you with the right treatment for you.
