Facial tumors affecting the facial nerve, while relatively rare, can have a profound impact on facial function and overall quality of life. Among these tumors, facial nerve schwannomas and geniculate ganglion hemangiomas are the most common.
Facial nerve schwannomas
Facial nerve schwannomas are benign tumors originating from Schwann cells, which provide support to the nerves throughout the body. These tumors tend to develop gradually, causing slow and continuous facial weakness. Patients often notice subtle changes in their facial symmetry, such as difficulty closing the eye or altered smiles, over extended periods.
