A young and brilliant graduate student came to the neurology department due to headaches and hearing loss. MRI scans revealed a large acoustic neuroma on the left side of her brain. Surgery was inevitable — but a complete resection, or even a slight surgical misstep, could cause facial paralysis. Facial paralysis means a crooked mouth, drooping eyelid, and the inability to close one eye — a devastating outcome for any young woman, both physically and emotionally.

After consultation at Huashan Hospital's Department of Neurosurgery, a multidisciplinary team carefully evaluated all possible treatment options. They finally decided on a strategy to remove most of the tumor while preserving facial nerve function, followed by CyberKnife radiosurgery to control the remaining tumor over the long term.The neurosurgical team at Huashan Hospital performed the operation with remarkable precision — the majority of the tumor was removed, and the facial nerve remained completely intact. Later, Professor Wang Enmin's team carried out fractionated CyberKnife treatment on the residual tumor. Using dose-sculpting techniques, they ensured that the tumor received a high therapeutic dose while minimizing radiation exposure to the facial nerve.

Following treatment, the patient experienced no facial paralysis. Regular MRI follow-ups showed gradual tumor shrinkage and stable neurological function. She regained her confidence, energy, and happiness.

By 2021 — eleven years after CyberKnife treatment — the residual tumor had significantly reduced in size. In April 2025, her MRI showed that the tumor had almost completely disappeared. When she returned to my clinic, her joy was beyond words. This case is a shining example of how multidisciplinary collaboration and the synergistic use of surgery and CyberKnife can provide patients with the most effective and life-changing treatment outcomes.
