Anterior Skull Base Surgery (Pituitary Surgery)

Anterior Skull Base Surgery (Pituitary Surgery): Precision Treatment for Complex Conditions

Anterior Skull Base Surgery is a highly specialized surgical technique used to treat complex conditions involving the skull base, particularly those that affect the pituitary gland. The pituitary gland is a small but vital structure located at the base of the brain, behind the bridge of the nose, and it plays a crucial role in regulating important bodily functions such as growth, metabolism, and reproduction.

At MicroCare ENT, we offer advanced pituitary surgery techniques, including transsphenoidal surgery and endonasal approaches, which allow for precise, minimally invasive removal of tumours located at the skull base.

What is Anterior Skull Base Surgery?

Anterior Skull Base Surgery involves accessing the skull base to treat a variety of conditions, including pituitary tumours, cysts, cranial nerve disorders, and vascular anomalies. The procedure is most commonly used to remove tumours located near the pituitary gland or surrounding structures, such as the optic nerves, sinuses, and cavernous sinuses.

There are two primary approaches to anterior skull base surgery:

Transsphenoidal Approach: The most commonly used method for pituitary surgery, this technique involves accessing the pituitary gland through the nasal cavity and sphenoidsinus. The surgeon makes a small incision inside the nose or under the upper lip, allowing access to the pituitary gland with minimal disruption to surrounding tissues.
Endonasal Approach: A variation of the transsphenoidal approach, this technique utilizes a rigid endoscopeto visualize the tumour and surrounding structures. The surgeon navigates the nasal cavity and sinus passages to reach the tumour, providing greater precision and minimizing incisions.

Both techniques allow for the removal of tumours with minimal scarring, reduced recovery time, and lower risk of complications compared to traditional open surgery.

Symptoms of a CSF Leak

The primary symptom of a CSF leak is a severe headache that is usually worse when standing and improves when lying down. Other symptoms may include:

Neck stiffness
Nausea and vomiting
Dizziness or vertigo
Tinnitus (ringing in the ears)
Visual disturbances
Clear fluid draining from the nose or ear

If left untreated, a CSF leak can lead to meningitis, an infection of the membranes surrounding the brain and spinal cord.

Conditions Treated by Anterior Skull Base Surgery

The most common condition treated with anterior skull base surgery is pituitary tumours, which can cause a range of symptoms due to the disruption of normal pituitary function, such as:

Hormonal imbalances (e.g., Cushing’s disease, acromegaly)
Vision problems, including visual field loss or optic nerve compression
Headaches, fatigue, and nausea
Infertility or irregular menstrual cycles

Additionally, anterior skull base surgery may be used to treat cranial nerve disorders, sinus tumours, vascular malformations, and other conditions affecting the skull base.

Benefits of Anterior Skull Base Surgery

Minimally Invasive: The transsphenoidal and endonasal approaches involve small incisions, which result in less pain, shorter recovery times, and a lower risk of infection compared to traditional open surgery.
Precision: The ability to use endoscopic technology allows surgeons to access delicate and hard-to-reach areas of the skull base with precision, minimizing the risk of damage to surrounding tissues such as the optic nerves and brain structures.
Quick Recovery: Most patients experience a faster recovery, with many returning to normal activities within a few weeks.
Reduced Risk of Complications: The minimally invasive nature of the surgery reduces the risk of complications such as infection, nerve damage, or scarring.
