What Is the Skull Base?

The skull base is the bony floor on which the brain rests. It contains openings for nerves and blood vessels and lies directly above the nasal cavity, sinuses and ears. Conditions arising here can press on the brain, eyes or major nerves.

Conditions That May Need Skull-Base Surgery

Skull-base surgery may be recommended for conditions such as:

  • Tumours of the pituitary region and nearby areas
  • Tumours of the nose and sinuses that extend toward the skull base
  • Some meningiomas and other benign or malignant growths
  • Cerebrospinal fluid (CSF) leaks from the nose

Endoscopic Endonasal Surgery

In many cases the skull base can be reached through the nostrils using a thin endoscope with a camera, avoiding any cut on the face or skull. This approach gives a magnified, close view and is often associated with less pain and a quicker recovery than traditional open surgery. It is only suitable for lesions in certain locations and of certain sizes.

A Team Approach

Skull-base surgery is usually done by a team of an ENT/head-neck surgeon and a neurosurgeon, working together with radiology, anaesthesia and oncology specialists.

Recovery

Recovery depends on the condition treated and the type of surgery. After endoscopic surgery patients commonly have nasal crusting and congestion for some weeks and need regular nasal cleaning and follow-up endoscopy. Your team will explain activity restrictions, medicines and warning signs such as clear fluid dripping from the nose or severe headache.

When to Seek an Opinion

Persistent one-sided nasal blockage, repeated nosebleeds, vision changes, double vision or unexplained headaches should be evaluated. Dr. Khan’s training includes skull-base surgery (Pittsburgh, USA).
