Skull Base Surgery at Trustwell Hospital

The skull base basically refers to the floor of the skull. It supports the brain and has openings through which nerves and blood vessels pass. Tumours and other problems here are hard to reach and sit close to critical structures. Modern imaging and endoscopic techniques now allow more precise treatment of many of these conditions. Trustwell Hospital approaches skull base surgery in Bangalore through coordinated, team-based care.

What Is Skull Base Surgery?

Skull base surgery treats abnormalities at the bottom of the skull, between the brain and the structures of the face, nose, and ear. Depending on the location, surgeons reach the area through endoscopic procedures done via the nose, the skull, a point above the eyebrow, or a combination of routes.

Conditions Treated with Skull Base Surgery

Pituitary Tumours

Most are benign growths in the pituitary gland. They can cause hormone imbalance or press on the optic nerves, affecting vision.

Acoustic Neuromas

Also called vestibular schwannomas, these are benign tumours of the hearing and balance nerve. Symptoms typically include hearing loss on one side, tinnitus, and imbalance.

Skull Base Meningiomas

They arise from the membranes surrounding the brain and are mostly harmless. That being said, their location makes removal difficult.

Cranial Nerve Tumours

Benign, slow-growing tumours arising from Schwann cells can affect other cranial nerves, causing numbness, weakness, or pain.

Other Benign and Malignant Skull Base Tumours

These include craniopharyngiomas, chordomas, chondrosarcomas, and certain sinonasal cancers that extend toward the skull base.

Selected Vascular and Structural Skull Base Disorders

Some cerebrospinal fluid (CSF) leaks, encephaloceles, and selected bone or vascular lesions may need skull base surgery. Suitability depends on the specific condition.

Types of Skull Base Surgery

Endoscopic Endonasal Surgery

A slim endoscope and instruments pass through the nostrils, so no facial or scalp incision is needed. It is commonly used for pituitary and some midline skull base lesions.

Minimally Invasive Skull Base Surgery

This covers approaches that use smaller openings, endoscopes, microscopes, and image guidance to limit disturbance to healthy tissue.

Open Skull Base Surgery

A craniotomy, a temporary opening in the skull, provides wider access. It remains important for large, complex, or laterally placed tumours.

Skull Base Tumour Removal

The aim is the safest possible removal, balancing completeness against preserving nerves, vessels, and brain function. Sometimes a planned partial removal is followed by radiation.

Pituitary Tumour Surgery

The usual route is endoscopic transsphenoidal surgery through the nose and sphenoid sinus. Larger or unusually shaped tumours may need other approaches.

Evaluation Before Skull Base Surgery

Before surgery, patients may need to undergo a neurological examination to assess vision, eye movements, facial sensation and strength, hearing, balance, and swallowing. MRI and CT imaging are also performed beforehand. Nasal endoscopy lets the ENT surgeon examine the nasal passages and sinuses if an endonasal route is used. Lastly, pre-surgical planning, such as visual field testing, audiometry, and hormone profiles for pituitary lesions, may be done. Together, these steps help the doctor choose the best path forward.

Multidisciplinary Approach to Skull Base Surgery

Neurosurgery: Neurosurgeons manage the brain, nerves, and the intracranial part of the tumour.
ENT / Head and Neck Surgery: ENT surgeons provide expertise in the nose, sinuses, and ear and often perform the endoscopic access.
Radiology and Imaging: Radiologists define tumour extent and its relationship to nerves and vessels.
Oncology Support When Required: For malignant tumours, or when radiotherapy or other treatment is considered, oncologists join the planning.

Benefits of Advanced Skull Base Surgery

Benefits can include:

Direct access to deep lesions
Reduced visible scarring
Reduced disturbance to normal brain tissue
Relief from pressure on nerves
Improved vision
Hormonal control
Possibly shorter hospital stays

Risks and Complications of Skull Base Surgery

Every operation carries risk. Skull base surgery is a complex procedure, and possible complications can include:

CSF leak
Infection
Bleeding or vascular injury
Cranial nerve injury
Pituitary hormone deficiency (pituitary surgery)
Nasal crusting or congestion (endonasal surgery)
Remaining tumour requiring additional treatment

Your surgeon can explain the risks in more detail based on your specific case. They may also recommend alternative paths such as radiosurgery or simple observation.

Recovery After Skull Base Surgery

Hospital Recovery

Patients are often monitored first in an intensive or high-dependency unit. The length of stay ranges from a few days to longer, depending on the surgery.

Neurological Monitoring

This includes checks for alertness, vision, facial movements, speech, and limb strength. Your fluid balance and hormone levels will be closely monitored after pituitary surgery.

Rehabilitation and Follow-Up

This includes an MRI scan, hormone testing when indicated and nasal care. You may be asked to avoid blowing your nose or straining for a period of time. Some require physical therapy, hearing or vision services, or speech and swallowing therapy.

Frequently Asked Questions (FAQs)

1. What is skull base surgery?

Skull base surgery targets the floor of the skull. Doctors perform it to treat tumours or other disorders in that area using endoscopic, minimally invasive, or open procedures.

2. Which conditions require skull base surgery?

These include pituitary tumours, acoustic neuromas, skull base meningiomas, cranial nerve tumours, some malignant tumours, and CSF leaks.

3. What is endoscopic skull base surgery?

A surgeon uses an endoscope through the nose to reach and remove lesions without an external incision.

4. Can pituitary tumours be treated with skull base surgery?

Yes. Endoscopic transsphenoidal surgery is a common approach for many pituitary tumours. However, doctors may suggest medication or radiation as alternatives.

5. Is skull base surgery minimally invasive?

It can be. Endoscopic procedures are much less invasive. Larger and complex tumours may require open surgery.
