Pituitary tumor surgery process

The pituitary gland is an important organ in the human brain. It plays a very important role in our daily life and work. Once the pituitary gland has a disease, such as a pituitary tumor, it will not only seriously affect daily life, but also have a great impact on physical health. In addition to conservative treatment, the most common method for treating pituitary tumors is surgical treatment. However, most people do not know much about the surgical process. What is the surgical process of pituitary tumors like?

What is pituitary tumor surgery like?

Pituitary tumors are a group of tumors that arise from the residual cells of the craniopharyngeal epithelium in the anterior and posterior pituitary gland. Pituitary tumors account for about 10% of intracranial tumors. Small tumors without symptoms are often discovered during autopsy. Preoperative preparation includes endocrine examination, imaging examination, drug preparation, and nasal drops and gargle with antibiotic solution one week before the operation. Nasal hair should be examined one day before the operation.

1. Peel off the nasal septum mucosa, approach through the nasal sphenoidal region, and perform routine disinfection and drape laying. The left nasal septum mucosa was incised and separated, and the upper edge of the nasal septum cartilage was separated and placed under a microscope for operation. At the same time, the nasal septum cartilage periosteum and nasal septum mucosa were separated to expose the left nasal septum cartilage until the anterior wall of the sphenoid sinus.

2. Remove the anterior wall of the sphenoid sinus, incise and peel off the sphenoid sinus mucosa, and use bipolar to shrink it to avoid unnecessary bleeding.

3. Cut the sella serrata. The window of the sella serrata bone should not exceed the inner edge of the carotid artery bulge.

4. Cut the dura mater at the sella turcica base. The range of the dura mater incision should be smaller than the bone window at the sella turcica base to avoid damaging the intercavernous sinus and causing bleeding.

5. Remove the tumor. Find the tumor and use specimen forceps to remove the tumor or use an aspirator to remove the tumor. There is no obvious boundary between microadenoma and normal pituitary gland, so the pituitary tissue surrounding the tumor should be removed at the same time to prevent tumor recurrence. Large adenomas can be removed using a scraper or suction device, while also preventing damage to the arachnoid membrane.

It is not difficult to see from the above that pituitary surgery is a complicated process. Therefore, after a patient develops a pituitary tumor, conservative treatment is best based on his or her own situation. After all, this type of surgery is very risky. At the same time, patients should also pay attention to follow-up treatment and protection after treatment, and strive for early physical recovery and normal work and life.
