Aundrea Aragon, 35, had a different experience for more than four months during which time a clear liquid leaked out of her nose whenever she bent over, but doctors kept telling her that it was just allergies and really nothing to worry. She knew something was terribly wrong because when she looked down or bent over, it would pour out of the left side of her nose. Doctors discovered much to their dismay that through two cracks in the back of her sphenoid sinus, her brain was leaking cerebrospinal fluid. This was indeed an extremely rare condition and a serious life threatening one at that. She underwent a surgery at the University of Arizona Medical Center in October. Doctors were not concerned about the loss of fluid they were more concerned about the prospect of infection setting in. Dr. Alexander G. Chiu, chief of the division of otolaryngology and his colleague, neurosurgeon Dr. G. Michael Lemole, used an endoscopic method to reach the sinus to patch up the cracks. They made an entry to the sinus through the nose and the leaky areas were covered with grafted skin. Doctors feel that the scar tissue would eventually grow over the graft and offer a life time of protection. Of course, she will need to be monitored for the rest of her life to make sure there are no fresh leaks cropping up.
