Endoscopic endonasal surgery

Surgical procedure accessing the skull base through the nasal cavity

Endoscopic endonasal surgery is a minimally invasive surgical technique that allows surgeons to access the skull base, sinuses, and certain parts of the brain through the nasal cavity. This approach utilizes an endoscope, a thin, flexible tube equipped with a camera and light, to provide a clear view of the surgical area.

Procedure

The procedure begins with the insertion of the endoscope into the nasal cavity. Surgeons use specialized instruments alongside the endoscope to navigate through the nasal passages and reach the target area. This technique avoids the need for external incisions, reducing recovery time and minimizing complications.

Indications

Endoscopic endonasal surgery is commonly used to treat:

• Pituitary tumors
• Cerebrospinal fluid leaks
• Sinusitis
• Skull base tumors

Advantages

The primary advantages of endoscopic endonasal surgery include:

• Reduced trauma to surrounding tissues
• Shorter recovery time
• Less postoperative pain
• Minimal scarring

Anatomy of the Nasal Cavity

Illustration of the nasal cavities

Understanding the anatomy of the nasal cavity is crucial for performing endoscopic endonasal surgery. The nasal cavity is divided into two passages by the nasal septum and is lined with mucous membranes. It connects to the paranasal sinuses and provides a pathway to the skull base.

Surgical Instruments

The instruments used in endoscopic endonasal surgery include:

• Endoscopes of various angles
• Microdebriders
• Suction devices
• Specialized forceps and scissors

Postoperative Care

After the surgery, patients typically experience nasal congestion and mild discomfort. Postoperative care includes:

• Nasal saline irrigations
• Avoidance of nose blowing
• Follow-up visits for endoscopic examination

Complications

While generally safe, potential complications of endoscopic endonasal surgery may include:

• Bleeding
• Infection
• Damage to surrounding structures
• Cerebrospinal fluid leak
