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[edit]

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[edit]

Endoscopic endonasal surgery is commonly used to treat:

Advantages[edit]

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[edit]

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[edit]

The instruments used in endoscopic endonasal surgery include:

Endoscopes of various angles
Microdebriders
Suction devices
Specialized forceps and scissors

Postoperative Care[edit]

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[edit]

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

Bleeding
Infection
Damage to surrounding structures
Cerebrospinal fluid leak

-'''Endoscopic endonasal surgery''' is a minimally invasive [[surgical procedure]] used to remove growths and correct abnormalities within the nasal passages and skull base. This technique utilizes an [[endoscope]], a thin, flexible tube with a light and camera at the end, allowing surgeons to navigate and operate through the nasal passages without making external incisions.

-==Overview==
+== Procedure ==
-Endoscopic endonasal surgery is primarily used for treating conditions such as [[pituitary tumors]], [[sinusitis]], [[skull base tumors]], and [[cerebrospinal fluid (CSF) leaks]]. By using the natural nasal passages as access points, this approach minimizes damage to surrounding tissues, leading to shorter recovery times and less postoperative discomfort compared to traditional open surgery.

-==Procedure==
+=== Indications ===
-During the procedure, the surgeon inserts the endoscope into the nostril to gain a detailed view of the surgical site. Specialized instruments are then passed through the same or another nostril to perform the surgery. The high-definition video from the endoscope allows for precise manipulation of tissues and structures. Depending on the condition being treated, parts of the nasal septum or skull base may be removed to access the target area.

-==Risks and Complications==
+== Surgical Instruments ==
-As with any surgical procedure, endoscopic endonasal surgery carries risks, such as infection, bleeding, and CSF leaks. However, the risk of complications is generally lower compared to open surgical approaches. It is crucial for patients to discuss the potential risks and benefits with their surgeon.
+The instruments used in endoscopic endonasal surgery include:

+* Specialized forceps and scissors
-==Recovery==
+== Postoperative Care ==
-Recovery times vary depending on the complexity of the surgery and the individual patient. Most patients can expect to spend a few days in the hospital for monitoring. Postoperative care typically involves nasal irrigation and avoiding strenuous activities for several weeks.
+After the surgery, patients typically experience nasal congestion and mild discomfort. Postoperative care includes:
