• Skull Base Tumors

    The treatment of tumors at the base of the skull, which include acoustic neuromas and meningiomas, requires special expertise and a collaborative effort. At the skull base are important structures, nerves and blood vessels that are vital to our function and appearance. Lahey Hospital & Medical Center is one of only a handful of medical institutions in the United States to offer comprehensive diagnostic, surgical and medical care across the full spectrum of cranial base disorders. 

    Types of Tumors

    Getting to the skull base surgically requires special exposure and closure techniques to prevent the leakage of cerebrospinal fluid. Tumors that demand this type of expertise include skull base meningiomas, glomus jugulare tumors, malignant nasopharyngeal tumors and acoustic neuromas. 


    Early symptoms of skull base tumors are very subtle, and they may progress without the patient's awareness. Depending on the tumor location, symptoms may include: hearing loss; ringing in the ear; facial pain; difficulty swallowing; loss of smell; visual loss; double vision; weakness or paralysis; seizures; and unsteadiness of gait. The diagnosis is made using a combination of state-of-the-art imaging techniques, including MRI scanning with gadolinium contrast, and other tests recommended by an otologist (such as hearing tests), and angiography. 


    For patients with acoustic neuromas who are in good health but show evidence of an active tumor, state-of-the-art microsurgery is advisable. Frequently,OR nurses preparing a patient for neurosurgery hearing can be saved if the facial nerve is preserved in tumor removal. Hearing and facial nerve function are generally monitored interoperatively.

    In certain circumstances, stereotactic radiosurgery is advisable. This treatment can slow the growth of a tumor, but it does not result in its complete removal. We prefer the use of radiosurgery in patients who are in poor health and who have progressive symptoms, particularly in the advanced age group. MRI scanning makes it possible to do serial evaluations of patients and determine whether surgery is necessary. Our team approach at Lahey Hospital & Medical Center allows us to provide optimal care for patients with acoustic neuromas.

    Our neurosurgery team works in collaboration with surgeons from the Department of Otolaryngology/Head and Neck Surgery, and plastic surgeons are often involved in complicated closures.
