 Schwannomas, also known as neurolemomas, are benign tumors that arise from Schwann cells, which are responsible for the formation of myelin around nerves. They typically occur in the head and neck region, but can be found elsewhere in the body. Facial nerve Schwannomas, FNS, are rare tumors that develop in the external auditory canal, parotid glands or other areas of the face. These tumors can cause facial paralysis if they grow large enough to compress the facial nerve. Surgical removal is the preferred treatment option, although radiation therapy may be used in some cases. This article was authored by Daniela Vrensinu, Mihai Demetru, Matei Popachirikinu, and others.
