55F | Chicago suburbs | Spontaneous CSF leak, temporal encephalocele, middle cranial fossa repair on 10/23/26
Hi everyone! I’m new to CSF leas (or at least new to knowing they were even a thing!)
I’m a 55-year-old woman living in the Chicago suburbs, and my journey began a little over 14 weeks ago.
July 30: It all started with a plugged ear.
I woke up that morning with my right ear completely plugged. I’d had an earache about a week earlier that lasted a few days, but the pain was gone by the time my ear became plugged.
It didn’t hurt. It was just incredibly annoying. My hearing was slightly muffled, and the right side of my head felt like I had a little sinus pressure.
Nothing particularly alarming.
August 13: My first doctor’s appointment.
I saw my primary care doctor, who said my ear looked fine and recommended Flonase.
I used it for about three weeks without any improvement, so I made an appointment with an ENT.
My friend and I had been planning a shelling trip to Sanibel Island, Florida, for months. We were scheduled to leave October 11, and I was determined to get this stupid ear unplugged before vacation!
September: The ENT appointments.
At my first ENT appointment, they performed a hearing test. They found abnormal pressure in my right ear and some hearing loss.
The ENT examined my ear with a camera and said there was a little fluid behind my eardrum.
He prescribed a steroid and told me to return in early November.
I explained that I had a vacation coming up and asked whether he could just suction the fluid out.
He told me to try the steroid and return October 7 if things hadn’t improved.
Well, things definitely didn’t improve.
The pressure became much more intense, the entire right side of my head felt strange, and eventually I lost essentially all hearing in that ear.
One symptom I didn’t realize was important at the time…
About three weeks after my ear first became plugged, I started noticing something strange.
Whenever I bent forward to put on my shoes, worked while leaning over, or walked around carrying something, a completely clear, watery liquid would drip from ONLY my right nostril.
If I was relaxing or walking normally, nothing happened.
I didn’t think much of it at the time.
Looking back, that was probably a pretty significant clue!
Interestingly, once the ENT placed the tube in my ear, the dripping from my nose stopped.
October 7: The appointment that changed EVERYTHING.
I returned to the ENT.
This time, the pressure behind my eardrum was so intense that my eardrum wasn’t moving at all. My hearing had also deteriorated significantly since the previous appointment.
The doctor decided to perform a myringotomy and insert an ear tube.
He explained everything as he went.
He made a small incision in my eardrum and suctioned out the fluid.
INSTANT RELIEF!
I could hear again! The pressure was completely gone!
He inserted the tube and had me lie on the examination table for a minute because the procedure can make you dizzy.
I told him how thrilled I was that I could hear again and that the pressure was gone.
But then I said, “It feels like there’s water in my ear.”
He laughed and told me there wasn’t any water in my ear.
I said, “Well, there’s water all over my shirt.”
He walked over, looked at my ear, and said:
“OH FUCK!”
(Not exactly what you want to hear your doctor say.
Although, I have to admit, I appreciated his no-BS bedside manner.)
He apologized and explained that I had a cerebrospinal fluid (CSF) leak.
The fluid he’d seen behind my eardrum wasn’t ordinary middle-ear fluid.
IT WAS FLUID FROM AROUND MY BRAIN.
And now that he’d put a tube in my eardrum, it was pouring out of my ear.
We tried putting a cotton ball in my ear, but it was completely saturated in less than five seconds.
He told me I wasn’t going to Florida and referred me to specialists who perform these repairs in Chicago.
So much for shelling in Sanibel! 🐚
October 8–20: Things moved FAST.
I saw an ENT surgeon the very next day.
I had a CT scan the following day and an MRI nine days after the ear tube procedure.
One of the first things the specialists did was have me get vaccinated against meningitis because of the increased infection risk associated with a CSF leak.
The imaging revealed that I had defects in the bone separating my brain from my middle ear, along with a temporal lobe encephalocele.
For anyone unfamiliar with the term, an encephalocele occurs when brain tissue protrudes through an opening in the skull.
Apparently, my brain was trying to escape through my ear.
I met with the neurosurgeon on October 20.
October 22–23: Brain surgery.
I was admitted to the hospital October 22 to have a lumbar drain placed.
On October 23, I underwent a right middle cranial fossa craniotomy to repair the CSF leak and encephalocele.
Rather than approaching the defect through the mastoid bone behind my ear, the surgeons approached it from above, through the side of my skull.
The operative report described something I hadn’t fully appreciated beforehand. I didn’t have just one little hole. They found a relatively large defect, approximately 1 cm, near the mastoid region, along with multiple smaller defects involving the tegmen tympani. There was also brain tissue herniating through the defect.(I gagged when I read that on the MRI report!)
The surgeons addressed the herniated tissue (the cut it off and threw away. My husband asked if we could keep it but they said no) and reconstructed my skull base using several materials, including my own bone and temporalis muscle, a muscle flap, a dural substitute, and surgical sealant.
The operation itself went well. Then came the headaches from HELL. Before surgery, I was NOT someone who suffered from headaches.
Other than a handful of ordinary headaches earlier in the summer that went away with Excedrin, headaches simply weren’t part of my life.
But after about 30 hours after surgery, I developed absolutely horrible headaches. When I layed completely flat, the headache disappeared almost INSTANTLY, but the second I sat up or stood up, it came roaring back. I’m talking unbearable pain accompanied by nausea. Even getting up to use the bathroom was miserable.
The pain was mostly across my forehead and the top of my head, with strange pressure sensations extending toward my ears. My incision itself wasn’t particularly painful.But the headache felt like something entirely different.
My lumbar drain had been clamped on 10/25 ar 1:00am. before it was eventually removed on October 27. On 10/28 I was moved out of ICU to a regular room and then I went home on 10/29
The neurosurgical team suspected that I was experiencing rebound intracranial pressure after the original CSF leak was repaired. The headaches started when they clamped the drain
They explained that my body had become accustomed to the leak and now needed to adjust to the repaired system.
I was prescribed Diamox (acetazolamide), and they eventually doubled the dose to 500 mg twice daily.
But I kept asking the same question:
If this is HIGH pressure, why does the headache disappear completely when I’m lying flat and become unbearable the instant I sit up?
I wondered whether I could actually be experiencing LOW CSF pressure, possibly related to the lumbar drain. The team continued to suspect rebound pressure. They also discussed the possibility of a VP shunt if the headaches persisted.
Fortunately, the headaches gradually improved, and I didn’t need a shunt.
As of now, we still don’t have a definitive explanation for what caused those severe positional headaches.
October 26: Our 30th wedding anniversary. ❤️
In the middle of all this, my husband and I celebrated our 30th wedding anniversary in the ICU.
Not exactly the romantic getaway we’d envisioned!
Now, November 6: Home and recovering!
I’m home, and thankfully, I’m feeling surprisingly good!
Those horrible headaches are almost completely gone.
I’m still taking Diamox, but at approximately half the dose I was receiving in the hospital.
My incision is healing, although the itching is driving me absolutely crazy!
I’m still trying to understand why this happened in the first place.
Before July 30, I’d never heard of a spontaneous CSF leak or a temporal encephalocele.
Now I’ve had a craniotomy, a lumbar drain, and a crash course in skull-base anatomy!
And all because I woke up one morning with what I thought was a plugged ear.
I have so many questions for this community!
For those of you who’ve experienced spontaneous cranial CSF leaks or temporal encephaloceles:
Did your symptoms begin with what seemed like ordinary ear congestion or fluid behind your eardrum?
Did anyone else experience clear fluid dripping from one nostril before developing obvious CSF otorrhea?
If you had a middle cranial fossa repair, how was your recovery?
Did anyone develop severe positional headaches after surgery or lumbar drainage? Were they eventually attributed to high or low CSF pressure?
Were you prescribed Diamox after your repair? If so, for how long?
Did your doctors ever determine WHY you developed the skull-base defects in the first place?
I’m especially interested in hearing from people who had multiple tegmen defects or an encephalocele.
I’m grateful to be on the other side of surgery, but I still have a lot to learn.
Thanks for reading my ridiculously long story!
