This is a collection of curated and illustrated 5-minute videos demonstrating common neurosurgical procedures performed by the Division of Neurosurgery. The aim is to stimulate interest, share the knowledge, and provide an opportunity for undergraduate medical students to have a taste of Neurosurgery in Action. We will include general and basic procedures in the beginning, and expand to more advanced operations later in the collection. Enjoy!

Cerebral vascular malformations can be classified by histopathology into 4 major types: Arterio-venous malformations (AVMs) Venous angiomas (developmental venous anomalies) Capillary telangiectasias and Cavernous malformations Arterio-venous malformations (AVMs) are congenital vascular lesions due to dysregulated angiogenesis. They are most often solitary but rarely could be multiple, in which case an underlying syndrome (e.g. hereditary haemorrhagic telangiectasia,…
This patient did not have any recent ocular symptoms but was noted to have significant right eye ophthalmoplegia during examination, whilst the left eye movements were completely normal. There was no double vision upon testing. Whilst one would need to consider a combined third, fourth and sixth nerve palsy in a patient with unilateral opthalmoplegia,…
This is a non-contrast cranial CT from a middle-aged man with multiple cardiovascular risk factors who suffered a severe ischaemic stroke involving the left middle cerebral artery territory. There was significant cytotoxic cerebral oedema as a result of the extensive infarction. The patient was operated on by the Neurosurgeons and a left hemi-craniectomy was performed…
The Parkinson-plus syndromes include 1) multi-system atrophy, 2) progressive supra-nuclear palsy and 3) corticobasal degeneration. Multi-system atrophy Multi-system atrophy (MSA) is a rare adult-onset sporadic neurodegenerative disorder. There are two main subtypes, as identified by its dominating symptomatology. MSA-P is when parkinsonian symptoms predominate, and MSA-C if cerebellar symptoms dominate. These two terms have replaced…
This patient complained of on and off tingling sensation over the lateral 3 ½ fingers of the right hand. There was wasting of the thenar muscles as noted in this photo. Further testing showed that the thumb abduction and opposition was weak. Tinel’s sign and Phalen’s test was positive. A nerve conduction study was performed,…
