TAIPEI (Taiwan News) — A team at Taipei Medical University Hospital removed a large brain tumor from a 40-year-old man surnamed Liu (劉) using minimally invasive surgery, avoiding the risks of a traditional open brain procedure, CNA reported. 

At a press conference on Friday, Chen Shu-mei (陳淑美), a neurosurgeon at the hospital, said that Liu’s tumor at the base of his brain was causing hormonal imbalances and increased brain pressure, leading to persistent headaches and sudden mood changes. Liu was diagnosed with the 2.5-cm tumor after experiencing heavy nosebleeds, along with facial nerve pain.

Chen noted the tumor near the base of the brain could affect vision and balance. Tumors in this area may also disrupt female hormone levels, potentially causing irregular periods and infertility.

Lin Che-hsuan (林哲玄), an ear, nose, and throat doctor at the hospital, said the team used a nasal endoscope to assess Liu’s nasal structure and plan the most suitable surgical approach before the surgery.

During the operation, the team guided a surgical tube through Liu’s nose to reach the brain and used a piece of tissue from the nasal septum to seal the base of the skull, reducing the risk of fluid leaks. Following the procedure, they monitored his recovery with an endoscope to prevent complications.

Lin noted the hospital’s operating room uses high-definition endoscopes, navigation technology, and real-time imaging, which help doctors precisely locate the tumor as well as nearby optic nerves, blood vessels, and brain tissue.

The hospital added that Lin’s tumor was not suitable for traditional open brain surgery. The minimally invasive procedure greatly reduced surgical risks and sped up recovery without affecting the man’s vision.

Liu has made a smooth recovery following the surgery, and his sudden mood swings have disappeared, the hospital said. MRI scans showed that his tumor had been completely removed.
