Hearing loss, balance problems and other concerns can be caused by tumors that form on the inner or middle ear. Tumors that grow on the middle ear are called glomus tumors. Tumors in the inner ear are called acoustic neuromas.These types of ear tumors are generally benign, but large or growing tumors require surgical treatment to ensure the symptoms are fully resolved.
How are Ear Tumors Treated?
Ear tumors may be treated with Gamma Knife radiosurgery if the tumor is not too large and is not causing severe symptoms. When an ear tumor affects hearing or balance and is causing concern due to size and growth, surgery is required to remove it. Gamma Knife radiosurgery may be combined with surgery to help ensure the tumor does not regrow.
Ear tumor surgery is performed under general anesthesia. The tumor is removed carefully through an incision in the middle ear or through a window incision created in the skull. A surgical microscope may be used for greater visibility and precision. Ear tumor surgery takes between 4-6 hours, depending on the size of the tumor.
During Gamma Knife radiosurgery, no incisions are required. The procedure takes between 20-60 minutes to deliver radiation to the tumor. The entire brain is not dosed, only the tumor. This treatment may be performed alone in certain cases, or in addition to the surgical procedure to help prevent the regrowth of the tumor or to stop or slow the growth of the tumor.
