Skull Base Surgery

Advanced ENT and Multidisciplinary Care in Sydney

Skull base surgery is a highly specialised field that involves treating complex conditions located at the junction of the brain, face, and neck. These surgeries are often performed to remove tumours, repair defects, or manage abnormalities at the base of the skull – a region that contains critical nerves, blood vessels, and the brainstem.

At Central Sydney ENT, Dr Arjuna Ananda works closely with neurosurgeons and other specialists to deliver advanced care using minimally invasive endoscopic techniques whenever possible. As Head of ENT at Royal Prince Alfred Hospital, Dr Ananda is experienced in managing both routine and rare skull base conditions.

Conditions Treated with Skull Base Surgery

Dr Ananda treats a range of conditions affecting the skull base, including:

  • Pituitary adenomas
  • Meningiomas
  • Acoustic neuromas (vestibular schwannomas)
  • Chordomas and esthesioneuroblastomas
  • Sinonasal tumours
  • Cerebrospinal fluid (CSF) leaks
  • Congenital defects or cysts

These conditions require careful evaluation and planning to ensure treatment is effective and safe, particularly given the proximity to vital brain and nerve structures.

Surgical Approaches

Endoscopic Skull Base Surgery
This is a minimally invasive technique performed through the nasal passages. It avoids external incisions and is often used for tumours like pituitary adenomas, sinonasal cancers, and CSF leak repairs.

Open Skull Base Surgery
This traditional approach may be required for larger or more invasive tumours that cannot be accessed endoscopically. It involves external incisions and is performed collaboratively with a neurosurgical team.

Combined/Multi-Team Approach
Some cases require a hybrid approach that combines endoscopic and open techniques, involving specialties such as ENT, neurosurgery, and occasionally ophthalmology. Dr Ananda performs most skull base surgeries endoscopically, with fewer than 20% needing combined access.

What to Expect Before Surgery

Before undergoing surgery, patients will typically have:

This process ensures that the surgical plan is safe, thorough, and tailored to preserve key functions such as vision, smell, and neurological health.

Frequently Asked Questions About Skull Base Surgery

Skull base surgery is used to treat conditions such as pituitary tumours, meningiomas, acoustic neuromas, CSF leaks, sinonasal cancers, and other benign or malignant growths near the base of the brain. It may also address congenital defects and vascular abnormalities.

No. While many procedures can be performed using endoscopic techniques through the nose, some complex cases require a combined or open surgical approach, particularly for large or invasive tumours. The chosen method depends on the location and extent of the condition.

Endoscopic surgery is minimally invasive, performed through the nasal passages without external incisions. Benefits include less visible scarring, shorter hospital stays, faster recovery, and a reduced risk of complications, when suitable for the condition.

Recovery varies based on the procedure. Most patients stay in hospital for a few days and return to normal activities within a few weeks. Ongoing care often includes follow-up imaging, nasal rinses, and multidisciplinary monitoring to support long-term outcomes.

Yes. Skull base surgery is often managed through a multidisciplinary team, including ENT surgeons, neurosurgeons, and sometimes ophthalmologists or oncologists. Dr Ananda works closely with these teams to provide coordinated, comprehensive care.
