Where is transsphenoidal?

Where is transsphenoidal?

Transsphenoidal surgery This is the most common way to remove pituitary tumors. Transsphenoidal means that the surgery is done through the sphenoid sinus, a hollow space in the skull behind the nasal passages and below the brain. The back wall of the sinus covers the pituitary gland.

What is the meaning of transsphenoidal?

(TRANS-sfee-NOY-dul SER-juh-ree) A type of surgery in which instruments are inserted through the nose and sphenoid sinus (a hollow space in a bone in the nose) to remove tumors that are in or near the pituitary gland.

Where is the incision for transsphenoidal hypophysectomy?

There are several types of hypophysectomy: Transsphenoidal hypophysectomy: The pituitary gland is taken out through your nose via the sphenoid sinus, a cavity near the back of your nose. This is often done with the assistance of either a surgical microscope or an endoscopic camera.

What is transsphenoidal hypophysectomy?

Transsphenoidal hypophysectomy is an effective surgical technique for removing pituitary and other intrasellar tumors with minimal morbidity and hospital stay.

What causes Macroadenoma?

It is not known exactly what causes a pituitary macroadenoma. Some people inherit gene mutations that increase their risk of developing these tumors. Other cases are sporadic, meaning there is no family history. Gene mutations may still be involved in sporadic cases.

What is transsphenoidal microsurgery?

Transsphenoidal microsurgery is a well-established neurosurgical procedure that has become the standard of care in the management of the majority of pituitary tumors and a select group of other sellar lesions. The safety of the procedure depends on the surgeon’s adherence to certain anatomic concepts.

What are the risks of pituitary tumor surgery?

Risks of endoscopic pituitary surgery

• CSF rhinorrhea. CSF, or cerebrospinal fluid, is the fluid that surrounds the brain, and it may leak from the nose after surgery.
• Meningitis.
• Damage to normal parts of the pituitary gland.
• Diabetes insipidus.
• Severe bleeding.
• Visual problems.

What can you not do after transsphenoidal hypophysectomy?

It is best not to blow your nose immediately after surgery, as this may cause bleeding. After 3 days, you may blow your nose gently. Clear fluid, like water dripping from a faucet, or a lot of bright red blood like a nosebleed is not normal.

What are the complications of transsphenoidal surgery?

Damage to a part of the pituitary gland that helps control urination may lead to frequent urination and thirst. Severe bleeding. Heavy and persistent bleeding into the brain or from the nose may occur if a large blood vessel is damaged during surgery. Visual problems.

Do microadenomas grow?

A microadenoma is less than one centimeter in size; a macroadenoma is one centimeter or greater in size. Aggressiveness. Nearly all pituitary adenomas are benign (noncancerous) and slow growing. An atypical pituitary adenoma, the rarer type, grows more quickly and is more likely to recur.

What is endoscopic endonasal transsphenoidal surgery?

In the last 2 decades, endoscopic endonasal transsphenoidal surgery has become the most popular choice of neurosurgeons and otolaryngologists to treat lesions of the skull base, with minimal invasiveness, lower incidence of complications, and lower morbidity and mortality rates compared with traditional approaches.

What are tendons in the knee?

Tendons are often overlooked as part of knee joint anatomy. They are they soft tissues found at the end of muscles which link the muscle to bone. The main tendon found at the knee is the patellar tendon which links the quads muscles to the shin bone. The knee cap actually sits inside the patellar tendon.

How has transsphenoidal surgery evolved over the years?

Transsphenoidal surgery has evolved much over nearly 100 years. Initially operations were performed often without any input from endocrinology colleagues, and without preoperative imaging, operative magnification and illumination.

What is the difference between transsphenoidal and transcranial procedures?

The transsphenoidal approach is the least traumatic nasal route to the sella turcica, avoids the need for brain retraction, and offers improved visualization of the surgical field. As a result, this approach has lower morbidity and mortality rates when compared with transcranial procedures ( 26 ).
