John Y. K. Lee MD, MSCE

Dr. Lee has a passion for minimally invasive ways to treat brain and skull base tumors. This passion is expressed as a commitment to endoscopic approaches to remove pituitary, clival, acoustic neuromas, and other skull-base tumors. Another expression of his interest in minimally invasive methods is his devotion to stereotactic radiosurgery, eg. "incision-less" brain surgery. 

In addition to brain tumors, Dr. Lee is committed to the comprehensive treatment of patients with craniofacial neuralgias, including trigeminal neuralgia, glossopharyngeal neuralgia, and hemifacial spasm. Dr. Lee uses minimally invasive, fully endoscopic surgical procedures including microvascular decompression (Jannetta procedure) and stereotactic radiosurgery to cure these disorders.

Dr. Lee continues to pioneer novel surgical techniques, most recently employing novel, near-infrared dyes to localize brain tumors in real time. This technique holds great promise for patients by capitalizing on fluorescent-guided tumor resection. He serves as a co-director of the Penn Center for Precision Surgery.
