For more than four months, a clear, tasteless liquid leaked out of Aundrea Aragon's nose whenever she bent over, but doctors reassured her that it was only allergies."It wasn't even dripping, it was pouring out of my nose," said Aragon, a
35-year-old mother from Tucson, Ariz. "If I looked down or bent over,
it would literally pore out of the left side of my nose. I had no
control at all."
Even though doctors "blew off" her concerns, Aragon said that "deep down," she knew something was seriously wrong, It was. Her brain was leaking cerebrospinal fluid through two cracks in
the back of her sphenoid sinus, a condition that could have killed her.
"I am still kind of in shock," said Aragon, who had surgery at the
University of Arizona Medical Center in October. "I was very fortunate.
They said I could get meningitis and go into a coma and die." Aragon's condition -- a cerebrospinal fluid leak -- is rare, occurring in only 1 in 100,000 or 1 in 200,000 patients, according to her surgeon, Dr. Alexander G. Chiu, chief of the division of otolaryngology. Most often it is seen in overweight patients who have high cranial
pressure, and the sinus "pops open." Sometimes a car accident or head
trauma can cause a tear.
"In her case, it was more of a freak thing," said Chiu, who has treated only about 100 cases.
The danger isn't the loss of fluid, according to Chiu, rather infection.
"You are constantly making brain fluid," he said. "It can be fatal when
there is a connection between the cleanest part of the body, the brain,
and the dirtiest part, the nose."
Chiu and his colleague, neurosurgeon Dr. G. Michael Lemole, used an
endoscopic method to access the sinus and patch up the two sinus cracks.
They entered the sinus through the nose and grafted skin over the leaky
spots.
University of Arizona is the only medical center to routinely perform
this procedure and and has the largest volume of endoscopic skull base
cases in the state.
In many other hospitals, surgeons repair these sinus cracks with a
craniotomy, which can cause a painful recovery, extensive scarring and
possible side effects.
