• Bio

    Dr Matthias Jaeger is a dually qualified Neurosurgeon, having trained in both Germany and Australia. He is a member of the Royal Australasian College of Surgeons.

    Dr Jaeger completed neurosurgical training in Germany in 2007, part of which was with Professor Madjid Samii, one of the most prominent and recognised Neurosurgeons worldwide. He then did further advanced training in Sydney, where he worked as a Specialist from 2010 - 2013. He has been practising in the Illawarra since 2013.

    Dr Jaeger has a comprehensive neurosurgical practice, covering all aspects of cranial, spinal and peripheral nerve conditions. He aims to provide the highest standard of neurosurgical care in line with the best medical evidence available.

    He has a specific interest in the management of cervical and lumbar spinal disease. His specific surgical cranial interests are brain tumour operations (including base of skull conditions), as well as the management of cerebrovascular disease and hydrocephalus, where he is providing ‘cutting edge’ diagnostic methods. He treats trigeminal neuralgia with microvascular decompression and percutaneous techniques.

    Dr Jaeger has been doing extensive research in the field of Neurosurgery (see publications). He is a conjoint Associate Professor at the University of New South Wales and actively maintains his academic and teaching interests with ongoing projects in the field of cerebral blood flow regulation, neuro-oncology, neuro-epidemiology and hydrocephalus.

    He has received research funding from the NHMRC and the University of New South Wales.
