How is pituitary adenoma surgery performed without cutting the skull?

Through the Endoscopic Endonasal Approach (EEA), the surgeon navigates directly through the patient's nostrils and sphenoid sinus to reach the pituitary fossa at the skull base. This natural corridor leaves no facial cut or scar and minimizes postoperative brain swelling.

What are the common warning symptoms of a skull base or pituitary tumor?

Common symptoms include progressive loss of peripheral vision (bitemporal hemianopsia), persistent severe headaches, hormonal imbalances (unexplained weight gain, prolactin elevation, acromegaly), one-sided hearing loss, ringing in the ear (tinnitus), or facial numbness.

How is the facial nerve protected during Acoustic Neuroma surgery?

Dr. Agnetia Vinoth utilizes continuous continuous Intraoperative Facial Nerve Electromyography (EMG) monitoring throughout acoustic neuroma resection, meticulously dissecting the tumor capsule away from the paper-thin seventh cranial nerve to preserve normal facial symmetry.

Mastering Complex Skull Base & Pituitary Pathologies

The skull base forms the intricate anatomical floor of the cranial vault, cradling critical neurovascular structures: the carotid arteries, brainstem, optic nerves, and cranial nerves governing facial sensation, eye movement, swallowing, and hearing. Tumors arising here require supreme surgical mastery to resect safely without compromising function.

Recognized for his surgical expertise in managing vascular and skull base pathologies, Dr. Agnetia Vinoth utilizes the Fully Endoscopic Endonasal Approach (EEA). By operating directly through natural nasal corridors, pituitary adenomas and anterior skull base tumors are cleared without visible external incisions, brain retraction, or cosmetic deformity.

Through-the-Nose Corridor

No incisions on the scalp or face. The optic chiasm is decompressed from below, safeguarding eyesight and visual fields.

Facial Nerve Preservation

Continuous intraoperative cranial nerve monitoring during vestibular schwannoma surgery protects facial expression and smile.

Frequently Asked Questions

Will my vision improve after pituitary tumor removal? ▼

In the vast majority of patients with visual loss caused by optic chiasm compression, vision begins improving dramatically within days or weeks following decompression, especially when treated before irreversible optic nerve atrophy sets in.

What is the recovery period after endoscopic endonasal surgery? ▼

Patients are usually out of bed the day after surgery and discharged within 3 to 4 days. Nasal packing is minimal or dissolvable. Normal light daily activities can resume within two weeks.

How do you prevent cerebrospinal fluid (CSF) leaks after surgery? ▼

Dr. Vinoth uses advanced multi-layer skull base reconstruction techniques, including vascularized nasoseptal flaps (Hadad-Bassagasteguy flap), fat grafts, and surgical sealant to ensure a watertight skull base barrier with leak rates under 2%.
