The majority of brain tumours treated at our division are brain metastasis, malignant glioma and meningioma. We worked closely with clinical oncologists in the Joint Brain Tumour clinic to offer tailored multi-modality treatment that combined surgery, LINAC-based stereotactic radiosurgery, chemotherapy and targeted therapy. To achieve maximum safety resection, awake craniotomy was employed in glioma surgery.

The majority of skull base tumours treated at our division are meningioma, chordoma and malignant head and neck tumours. We employed both open and expanded endonasal approaches to minimize morbidity while achieving maximal resection. The expanded endonasal approach provides a direct route to attack skull base tumour and avoid brain retraction during open approach.

In addition to the development of endoscopic transsphenoidal surgery for pituitary tumour in the last decade, our division has also pioneered the simultaneous combined transcranial-transsphenoidal approach to giant pituitary adenoma. This approach has enabled us to achieve complete resection of large pituitary tumours safely in a single setting which previously would require two separate procedures.

We work closely with the Division of Head and Neck Surgery, and the Division of Plastic and Reconstruction Surgery in treating skull base tumours and we have acquired extensive experience in craniofacial resection for anterior skull base lesions such as olfactory neuroblastoma and recurrent head and neck cancer.

Movement disorders such as Parkinson's disease, dystonia and Tourette syndrome refractory to medical therapy are treated at our unit with deep brain stimulation (DBS). We are one of the designated centers in Hong Kong performed DBS and performed the first DBS on Tourette syndrome patient in Hong Kong.

We perform various types of surgical procedures for refractory epilepsy including hippocampectomy, resection of epileptic focus, vagal nerve stimulation, as well as microvascular decompression for pain syndrome, such as trigeminal neuralgia.
