Minimally Invasive Approaches to Pituitary Tumours:
What is pituitary tumour removal?
Pituitary tumour removal is a surgical procedure designed to eliminate abnormal growths in the pituitary gland. It can affect hormone regulation and overall health.
- The most common method is transsphenoidal surgery, where surgeons access the tumour through the nasal cavity, minimising invasiveness and recovery time.
- In cases of larger or more complex tumours, a craniotomy opening in the skull for direct access may be necessary.
- Advanced techniques, such as neuro-navigation systems, intraoperative MRI, and robotic-assisted surgery, enhance precision and reduce complications.

What symptoms usually lead to the diagnosis of a pituitary tumour?
Symptoms of a pituitary tumour vary depending on its size and whether it affects hormone production. Common signs include vision problems, such as blurred or double vision, and gradual loss of peripheral vision due to pressure on the optic nerves. Frequent headaches may also occur as the tumour grows.
Hormonal imbalances can lead to fatigue, unexplained weight changes, menstrual irregularities, erectile dysfunction, and decreased libido. Some tumours cause excess hormone production, leading to conditions like Cushing’s disease (excess cortisol) or acromegaly (excess growth hormone), which results in enlarged facial features and hands.
In severe cases, large tumours may press on the pituitary gland, causing low blood pressure, dizziness, and loss of consciousness. If the tumour affects vasopressin production, it can lead to diabetes insipidus, causing excessive thirst and frequent urination.
How is the type and size of the pituitary tumour determined before surgery?
Before surgery, neurosurgeons assess the type and size of a pituitary tumour through imaging scans, hormone evaluations, and vision tests to ensure precise diagnosis and treatment planning.
- MRI and CT Scans provide detailed images of the location, size, and impact on surrounding structures.
- Blood and Urine Tests measure hormone levels to identify whether the tumour is producing excess hormones.
- Vision Testing checks for optic nerve compression, which can indicate tumour growth.
What are the different surgical options available for removing pituitary tumours?
Pituitary tumour removal typically involves two main surgical approaches:
- Transsphenoidal Surgery – The most common method where surgeons access the tumour through the nasal cavity. This minimally invasive technique reduces recovery time and avoids external scarring.
- Craniotomy – Used for larger or more complex tumours, requiring an opening in the skull to access the pituitary gland. This approach provides better visibility but involves a lengthy recovery period.
Both techniques aim to preserve brain function while effectively removing the tumour.

What are the key risks or complications involved in pituitary tumour surgery?
Pituitary tumour surgery carries several risks and potential complications, depending on the approach used and the size and location of the tumour. Some key concerns include:
- Damage to Surrounding Structures – The pituitary gland is near critical brain areas, and surgery may affect nearby nerves or blood vessels.
- Hormonal Imbalances – Removing or disturbing the pituitary gland can lead to hormone deficiencies, requiring lifelong hormone replacement therapy.
- Vision Problems – If the tumour is close to the optic nerves, surgery may cause temporary or permanent vision changes.
- Infection or Bleeding – As with any surgery, there is a risk of infection or excessive bleeding, particularly in craniotomy procedures.
- Cerebrospinal Fluid (CSF) Leak – In some cases, surgery may cause a leak of CSF, requiring additional treatment.
What is the typical recovery time after pituitary tumour removal?
Recovery time after pituitary tumour removal depends on the surgical approach and individual health factors.
- Transsphenoidal Surgery – Most patients stay in the hospital for 2 to 5 days and resume normal activities within 2 to 4 weeks.
- Craniotomy recovers longer, with hospital minimum stays of 5 to 10 days and a gradual return to daily activities over several weeks.
Common post-surgery effects include fatigue, nasal congestion, and hormonal adjustments, which may require ongoing monitoring.
Will the patient need hormone replacement therapy after surgery?
Hormone replacement therapy may be necessary after pituitary tumour surgery, depending on how much of the gland is affected. If the surgery disrupts hormone production, patients might need lifelong medication to regulate thyroid, adrenal, or reproductive hormones. Doctors monitor hormone levels post-surgery and adjust treatment accordingly.
How often is follow-up imaging (MRI/CT) required post-surgery?
Follow-up imaging after surgery depends on the type of procedure and individual recovery needs. For lung cancer patients, guidelines suggest imaging every 3, 6, or 12 months post-surgery, but studies indicate that more frequent scans may not necessarily improve survival rates. In oncology, experts recommend standardised follow-up schedules using MRI, CT, and PET-CT to assess treatment success and detect recurrence.

What are the chances of tumour recurrence, and how is it managed?
Tumour recurrence depends on type, stage, and treatment approach. Some cancers have high recurrence rates, such as glioblastoma and ovarian cancer, while others, like early-stage breast cancer, have lower risks.
Managing Recurrence
- Regular Monitoring – Follow-up imaging (MRI, CT) helps detect recurrence early.
- Targeted Therapy & Immunotherapy – Advanced treatments improve outcomes for recurrent tumours.
- Lifestyle & Preventive Care – Healthy habits and medical supervision reduce recurrence risks.
What is life after pituitary tumour removal?
Life after pituitary tumour removal varies depending on the type of surgery, tumour size, and individual health factors. Most patients experience gradual recovery, with some requiring hormone replacement therapy if the pituitary gland’s function is affected.
Key Aspects of Life After Surgery
- Physical Recovery – Fatigue, headaches, and nasal congestion (for transsphenoidal surgery) may persist for a few weeks.
- Hormonal Adjustments – Regular hormone level monitoring ensures proper balance; a few patients may need lifelong medication.
- Vision & Cognitive Changes – If the tumour affects the optic nerves, vision may take time to stabilise. Some patients report mild memory or concentration issues.
- Follow-Up Care – Routine MRI or CT scans help detect recurrence, and endocrinologists monitor hormone function.
Conclusion:
Pituitary tumour removal is a complex yet effective procedure that has advanced significantly with minimally invasive techniques, robotic-assisted surgery, and AI-powered precision tools. While surgery offers a high success rate, careful post-surgical management, including hormone regulation and regular follow-ups, is essential for long-term well-being. With ongoing innovations in neurosurgery and endocrinology, patients benefit from safer procedures, faster recoveries, and improved quality of life after treatment.
