Understanding Skull Base Tumors
Skull base tumors are a group of growths that happen at the skull’s base. They can be either good or bad, making them hard to diagnose and treat.
Types of Skull Base Tumors
Meningioma, craniopharyngioma, and chordoma are common types. Meningiomas are usually not cancerous and come from the meninges, which protect the brain and spinal cord. Craniopharyngiomas are mostly not cancerous but can grow fast and happen in young people. Chordomas are rare and cancerous, coming from notochord leftovers, usually near the spine or clivus.
Pituitary adenomas are also common. They’re usually not cancerous but can mess with hormones.
Symptoms and Diagnosis
Skull base tumors can cause headaches, vision problems, and issues with cranial nerves. The symptoms depend on the tumor’s type and where it is. For example, craniopharyngiomas can cause hormone problems, while meningiomas might lead to seizures or nerve damage.
To diagnose these tumors, doctors use advanced scans. MRI and CT scans are key. MRI shows soft tissues and blood vessels well, while CT scans are great for seeing bones. This helps doctors plan surgeries.

Step-by-Step Procedure of Intranasal Tumor Resection
The first step in removing a nasal tumor is making the patient comfortable. They get general anesthesia so they won’t feel anything during the surgery. This keeps them safe and comfy.
Next, the surgeon puts an endoscope into the nose. This tool lets the surgeon see the area very clearly. It helps them remove the tumor with great accuracy.
Then, the surgeon uses special tools to get to and remove the tumor. They must be very careful not to touch important parts like blood vessels or nerves. They cut, cauterize, and take out the tumor bit by bit.
While removing the tumor, the surgeon keeps the area clean with water and suction. They use different tools through the endoscope to help with the removal.
Once the tumor is gone, the surgeon checks the area carefully. They stop any bleeding and clean the area well. Finally, they close the nose with stitches or special glue.
| Procedure Step | Description |
|---|---|
| Anesthesia | General anesthesia administration to ensure patient comfort. |
| Insertion of Endoscope | Endoscope enters through the nasal cavity, providing visualization. |
| Tumor Dissection | Precise dissection and removal of the tumor with specialized instruments. |
| Hemostasis and Cleaning | Inspection and cleaning of the surgical site, ensuring no residual tumor. |
| Closure | Closing of nasal passage incisions with sutures or hemostatic agents. |
This guide shows how important modern surgery and tools are for removing nasal tumors safely. Using an endoscope is key for precise surgery. Intranasal Access for Skull Base Tumor Resection
Potential Risks and Complications
Skull base surgery has made big steps forward, but risks and complications are still there. It’s important to understand and manage these risks for the best results.
Intraoperative Risks
During skull base surgery, there are risks that can happen during the surgery. Bleeding is a big worry because it can make it hard to see and can make the surgery harder. Damage to important nerves or blood vessels is also a big risk and can lead to serious problems.
Cerebrospinal fluid leaks are another risk. Surgeons must be very careful to avoid this.
Postoperative Complications
After surgery, patients may face challenges as they heal. Infections can happen, which can slow down healing and make it more painful. Nasal stuffiness and blockages can also happen, making it hard to breathe and affecting daily life.
Some patients may take longer to heal, which can mean more doctor visits and treatments.
Studies look at these complications and how to lessen them. By following certain rules for surgery and aftercare, doctors can help patients feel better and recover faster.
| Complication | Frequency | Mitigation Measures |
|---|---|---|
| Bleeding | 20% | Enhanced visualization techniques, blood management protocols |
