CSF Leak Repair

CSF or cerebrospinal fluid leak is when the protective fluid (CSF) encircling the brain leaks into the ears or the sinuses.

Generally, the brain is a sterile compartment separated from the ear and the sinuses by a bony separation known as the skull base. CSF cushions and surrounds the brain.

A leathery, thick tissue called dura lines the inside of the skull, providing a seal that prevents the spinal fluid from escaping. Cerebrospinal fluid leaks occur when there is a breakdown in the barrier.

The dura can be damaged by head trauma, tumors, and certain surgeries. CSF left untreated can lead to life-threatening brain infections, meningitis, or stroke.

What are the Symptoms of CSF Leak:

Common symptoms of a CSF leak include:

  • A headache that gets worse upon sitting up and eases upon lying down.
  • Clear drainage from the nose or the ear when straining or leaning forward.

How is CSF Leak Diagnosed?

Our doctor might use a variety of tests to diagnose a cerebrospinal fluid leak, which includes:

  • MRI scan
  • CT scan
  • Nasal endoscopy
  • Testing of nasal secretions

Treatment for CSF leak:

Depending on the location of the leak, the treatment of CSF leak may vary. Leaks into the sinuses can be repaired through minimally invasive endoscopic procedures. Cerebrospinal fluid leak from the ear typically requires open surgery.

Endoscopic Repair of Cerebrospinal Fluid Leak Rhinorrhea (Drainage from the Nose):

In this procedure, our doctor accesses the leak through the patient's nose, avoiding any external incision. Small tissue from the nasal lining is placed on the site after the location of the leak has been precisely located.

This procedure carries far less risk than an open approach.

Repair of Cerebrospinal Fluid Leak Otorrhea (Drainage from the Ear):

A cerebrospinal fluid leak into the ear requires traditional surgical incisions. The options for surgery depends upon the location of the leak.

If the leak is toward the back of the skull, outpatient surgery can usually correct the problem. In case the leak is near the center of the skull, it requires a craniotomy.

What can you Expect After CSF Leak Repair?

To ensure the surgery is successful and the recovery is complete, each patient's recovery plan is tailored.

Patients are placed on bed rest for typically two to three days to help facilitate the healing process and closely monitor leak recurrence.

It can take up to four to six weeks to heal completely. During this time, the patient's activity will be restricted to avoid heavy lifting, straining, and nose blowing.
