Skull Base TumorsJuly 31st, 2012 | Posted by in Benign Tumor Types
Many different tumor types originate from or extend into the base or bottom of the skull, upon which the brain rests. Because the front of the skull base slopes down behind the eyes and nasal cavities, skull base tumors require considerable surgical skill to avoid damage vital nerves and tissues. Skull base tumors may be benign or malignant and produce few symptoms until they grow large enough. Symptoms vary depending of the location and size of the tumor and may include facial pain or numbness, headache, recurrent sinusitis, cranial nerve palsies, nasal obstruction, shortness of breath, hoarseness, hearing loss or tinnitus (ringing in the ears). Increasingly, skull base tumors may be excised using endoscopic surgery through the nasal passages, but many still require open surgery. The tumor may be excised through traditional open surgery or endoscopic microsurgery through the nasal passages. In some causes, particularly when the entire tumor cannot be safely removed, surgery is followed by radiation therapy, which can be traditional or gamma knife surgery.
