What is endoscopic endonasal surgery?
In endoscopic endonasal surgery, a scope and instruments pass through the nostril and sphenoid sinus to reach the pituitary gland or selected skull-base lesions. The endoscope provides a close view, but it does not make every tumour suitable for this route or mean that all brain surgery is performed through the nose.
How is the surgical route selected?
The choice depends on the lesion type, size and extension, its relationship to blood vessels and nerves, sinus anatomy and the patient's health. Planning commonly includes review of MRI and other appropriate imaging; hormone and vision assessments may be needed. For selected cases, neurosurgery and ENT or rhinology teams work together.
Benefits, risks and follow-up
For some lesions, the nasal route can provide access without opening the skull, but possible risks include cerebrospinal fluid leak, pituitary hormone problems or visual changes, as well as general surgical risks. Follow-up depends on the operation and may include hormone tests, imaging and vision review.
Does every pituitary tumour need surgery?
No. Options may include observation, medication or surgery depending on tumour type, hormone activity, size, effect on vision and overall health. New or worsening visual symptoms need prompt medical assessment. The clinic provides consultation and medical care; surgery, when indicated, takes place in hospital after discussing alternatives and risks.
Frequently asked questions
Is endoscopic pituitary surgery performed through the nose?
For many selected cases, the surgeon uses a route through the nose and sphenoid sinus. The appropriate route depends on the tumour and its extension.
Does every pituitary tumour need removal?
No. Observation, medicines or surgery may be considered depending on diagnosis, symptoms and test results.
What tests may be needed before pituitary surgery?
Assessment may include MRI, vision and hormone testing, and other investigations based on the tumour and team plan.
Does endoscopy remove the risks of surgery?
No. Risks may include cerebrospinal fluid leak, hormone disturbance or vision changes; the team discusses individual risks before treatment.
