Name of the Procedure:

Craniotomy for Repair of Dural/Cerebrospinal Fluid Leak, Including Surgery for Rhinorrhea/Otorrhea

Summary

A craniotomy for the repair of a dural or cerebrospinal fluid (CSF) leak involves surgically opening the skull to access the brain and repair leaks in the dura mater, the outer membrane covering the brain. These leaks can cause CSF to escape, leading to conditions like rhinorrhea (CSF leakage through the nose) or otorrhea (CSF leakage through the ear).

Purpose

This procedure is intended to address and repair dural and CSF leaks that may result from trauma, surgery, or certain medical conditions. The primary goal is to stop the leakage of CSF to prevent infection, relieve symptoms, and improve the patient’s quality of life.

Indications

• Persistent headaches or neck pain
• Clear fluid drainage from the nose or ear
• History of head trauma or previous brain surgery
• Signs of meningitis without a clear source
• Radiological evidence of a dural or CSF leak

Preparation

• Fasting for at least 8 hours before the procedure
• Discontinuation of certain medications as advised by the doctor
• Preoperative imaging studies (e.g., MRI, CT scan) to identify the leak source
• Preoperative blood tests and medical clearance

Procedure Description

1. The patient is placed under general anesthesia.
2. An incision is made in the scalp to expose the skull.
3. A portion of the skull (bone flap) is removed to access the dura mater.
4. The surgeon identifies and repairs the leak using sutures or a patch.
5. The bone flap is replaced, and the scalp incision is closed with sutures or staples.
6. The area is dressed, and the patient is moved to the recovery area.

Duration

The procedure typically takes 2 to 4 hours, depending on the complexity of the leak and surgical access.

Setting

This surgery is performed in a hospital's operating room, often under the neurosurgical team’s guidance.

Personnel

• Neurosurgeon
• Anesthesiologist
• Operating room nurses
• Surgical techs
• Recovery room staff

Risks and Complications

• Infection
• Bleeding
• Brain swelling
• Neurological deficits (e.g., speech, movement disorders)
• Recurrence of the leak
• Adverse reactions to anesthesia

Benefits

• Elimination of CSF leaks
• Relief from associated symptoms, such as headaches and infections
• Prevention of potential complications, like meningitis
• Improved overall quality of life

Recovery

• Hospital stay of 3-7 days for monitoring
• Gradual resumption of normal activities over several weeks
• Follow-up visits with the neurosurgeon
• Temporary restrictions on physical activities
• Pain management with prescribed medications

Alternatives

• Conservative management: Bed rest, hydration, and caffeine to reduce CSF pressure
• Less invasive endoscopic repair approaches
• Identification and treatment of underlying causes, such as infection or structural abnormalities

Patient Experience

During the procedure, the patient will be unconscious under general anesthesia. Post-operatively, the patient may experience headaches, incision site pain, and fatigue. Pain management and rest are crucial components of the recovery process, and close follow-up with the healthcare team ensures optimal healing and detection of any early complications.
