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''' (EES) is a minimally invasive surgical technique that allows surgeons to access the skull base and certain regions of the brain through the nasal passages. This approach utilizes an [[endoscope]], a thin, flexible tube equipped with a camera and light, to provide visualization 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.
-==Overview==
+=== Indications ===
-Endoscopic endonasal surgery is primarily used to treat conditions affecting the [[skull base]], [[sinuses]], and certain brain regions. It is a preferred method for removing [[pituitary tumors]], repairing [[cerebrospinal fluid]] leaks, and addressing other abnormalities located at the base of the skull.
+Endoscopic endonasal surgery is commonly used to treat:
+* [[Pituitary tumors]]
+* [[Cerebrospinal fluid leaks]]
+* [[Sinusitis]]
+* [[Skull base tumors]]
-==Procedure==
+=== Advantages ===
-The procedure involves inserting an endoscope through the nostrils to reach the target area. The endoscope provides a magnified view of the surgical field, allowing the surgeon to operate with precision. Specialized instruments are used alongside the endoscope to perform the surgery.
+The primary advantages of endoscopic endonasal surgery include:
+* Reduced trauma to surrounding tissues
+* Shorter recovery time
+* Less postoperative pain
+* Minimal scarring
-===Steps===
+== Anatomy of the Nasal Cavity ==
-. '''Anesthesia''': The patient is placed under general anesthesia.
+[[File:Illu_nasal_cavities.jpg|thumb|left|Illustration of the nasal cavities]]
-. '''Endoscope Insertion''': The endoscope is carefully inserted through the nasal cavity.
+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.
-. '''Navigation''': Surgeons use image guidance systems to navigate to the surgical site.
-. '''Surgical Intervention''': Using endoscopic tools, the surgeon performs the necessary intervention, such as tumor removal or leak repair.
-. '''Closure''': The surgical site is closed, often using tissue grafts to ensure proper healing.
-==Advantages==
+== Surgical Instruments ==
-Endoscopic endonasal surgery offers several advantages over traditional open surgery:
+The instruments used in endoscopic endonasal surgery include:
-* '''Minimally Invasive''': Reduced trauma to surrounding tissues and faster recovery times.
+* Endoscopes of various angles
-* '''No External Incisions''': The procedure is performed entirely through the nostrils, leaving no visible scars.
+* Microdebriders
-* '''Improved Visualization''': The endoscope provides enhanced visualization of the surgical area.
+* Suction devices
+* Specialized forceps and scissors
-==Applications==
-EES is used to treat a variety of conditions, including:
-* [[Pituitary adenomas]]
-* [[Craniopharyngiomas]]
-* [[Meningiomas]]
-* [[Chordomas]]
-* [[Cerebrospinal fluid leaks]]
-==Risks and Complications==
+== Postoperative Care ==
-While EES is generally safe, it carries potential risks and complications, such as:
+After the surgery, patients typically experience nasal congestion and mild discomfort. Postoperative care includes:
-* [[Infection]]
+* Nasal saline irrigations
-* [[Bleeding]]
+* Avoidance of nose blowing
-* [[Cerebrospinal fluid leak]]
+* Follow-up visits for endoscopic examination
-* [[Vision problems]]
-==Postoperative Care==
+== Complications ==
-After surgery, patients may experience nasal congestion and mild discomfort. Follow-up care includes:
+While generally safe, potential complications of endoscopic endonasal surgery may include:
-* Regular check-ups to monitor healing
+* Bleeding
-* Nasal irrigation to keep the nasal passages clear
+* Infection
-* Avoidance of strenuous activities for a specified period
+* Damage to surrounding structures
+* Cerebrospinal fluid leak
