Skull Base Surgery Center

Until recently the only option for patients with large, complex tumors in the skull base (the floor of the cranium) was craniotomy — the surgical opening of the skull. Because of the many critical neural and vascular structures in this area, skull base surgery is risky. Although craniotomy has become safer in recent years, it can still cause significant harm.

With the advent of minimally invasive approaches and new discoveries in intra-operative monitoring, Mount Sinai neurosurgeons have become highly adept at treating skull base tumors in ways that eliminate facial scarring, reduce overall surgery times, and avoid some of the complications of traditional open surgery.

Eric Genden, MD, Chair of the Mount Sinai Department of Otolaryngology, and Joshua Bederson, MD, Chair of the Mount Sinai Department of Neurosurgery, are pioneers in minimally invasive skull base surgery.

Mount Sinai's Skull Base Surgery Center treats a variety of skull base conditions, including cerebrospinal leaks, chondrosarcomas, malignant sinonasal tumors, skull base meningiomas, and vascular lesions, as well as:

  • Acoustic Neuromas
    Mount Sinai has made important contributions to the management of these benign tumors, which produce dizziness, tinnitus, and hearing loss. While hearing loss and weakness of the face may result from the operation to remove acoustic neuromas, the majority of patients treated here experience no facial weakness or minimal temporary facial weakness. Similarly, hearing is preserved for a large percentage of patients, depending upon the pre-operative hearing level and tumor size. Early diagnosis and treatment are critical to achieving excellent operative results, which Mount Sinai reports to be on par with few top institutions in the world.

  • Tumors at the Base of the Brain
    Previously, these tumors (most of which are benign) were considered either inoperable or only partially removable because of their location deep beneath the brain. Further complicating the situation, important nerves and blood vessels surround the area. Within the last few years, however, progress in imaging techniques, intraoperative monitoring, microsurgery, and newer surgical approaches has considerably advanced the treatment of such tumors and thereby improved results.

Mount Sinai’s multidisciplinary Clinical Center for Skull Base Surgery has extensive experience in treating such disorders. Its well-known team pioneered work in the reconstruction of the arteries at the base of the brain and in microvascular free tissue transfer. Both techniques are constantly being studied and evaluated in a dedicated laboratory. Innovative approaches and management strategies have been devised by the surgeons to treat these difficult problems.

Minimally invasive approaches are feasible for some patients, and complete excisions are even possible. If minimally invasive techniques are not possible for your condition, our physicians will recommend the best alternative treatment.
