Pituitary Tumor
The pituitary gland, often called the master gland, plays a crucial role in regulating hormones that control growth, metabolism, and other vital body functions. A pituitary tumor occurs when abnormal cells grow in this small but important gland located at the base of the brain. While most pituitary tumors are benign (non-cancerous), they can cause significant hormonal imbalances and compress nearby structures, particularly the optic nerves, leading to vision problems, fatigue, or unexplained weight and mood changes.
Traditional surgery to access the pituitary gland required a craniotomy (opening the skull). However, with the advancement of endoscopic transnasal surgery, this procedure can now be performed through the natural nasal passage — avoiding any external incisions.
Endoscopic transnasal surgery is a minimally invasive approach used to access pituitary and certain skull base tumours through the nasal passages. The procedure uses an endoscope to provide visual access to the surgical area without requiring an external incision in the skull.
This approach not only preserves normal pituitary function but also reduces hospital stay, postoperative pain, and cosmetic concerns. It represents the cutting-edge evolution of pituitary surgery in modern neurosurgery — offering hope to patients with both functional and non-functional pituitary adenomas.
Clinical Management
The management of pituitary tumors begins with a detailed clinical and hormonal evaluation. Patients often present with symptoms like persistent headaches, visual disturbances (especially loss of peripheral vision), unexplained fatigue, infertility, or hormonal excess such as in Cushing’s disease or acromegaly. Advanced MRI imaging of the brain and pituitary region helps determine the size, extent, and direction of the tumor.
Once diagnosed, Dr. Rahul Gupta and his multidisciplinary team — including endocrinologists and neuro-ophthalmologists — create a personalized treatment plan. For many pituitary tumours, endoscopic transnasal surgery may be considered depending on the tumour’s size, location, and relationship to surrounding structures. The appropriate surgical approach is determined through clinical assessment and imaging.
Through one of the nostrils, a thin endoscope equipped with a high-definition camera provides a magnified view of the tumor area. Using specialized microsurgical instruments, the tumor is carefully removed through this corridor without disturbing surrounding brain tissue.
This technique allows for excellent tumor clearance while minimizing trauma. In some cases, where the tumor is very large or extends into the cavernous sinus, a staged or combined approach may be used. If the tumor produces excess hormones, medical therapy may be prescribed post-surgery to stabilize hormonal balance.
Recovery is typically rapid, with patients often resuming normal activities within a few days. Dr. Gupta’s patients benefit from an integrated postoperative care program involving endocrinological follow-up, nasal care, and regular MRI surveillance to ensure complete recovery and monitor for recurrence.
Endoscopic transnasal pituitary surgery involves accessing the pituitary gland through the nasal passages and a natural opening in the skull base. Potential benefits include avoiding a large external incision and reducing disruption to surrounding tissues. Possible risks, suitability, and recovery vary according to the individual case and should be discussed with the treating specialist.
