is a salty fluid leaking from the nose, especially with exertion
Nasal or sinus surgery
can rarely cause the problem of Cerebrospinal Fluid Leak.
Commonly known as CSF
rhinorrhea, a condition involving a defect in the bone and soft
tissue barrier between the brain and the sinuses.
Fluid that surrounds
the brain called cerebrospinal fluid (CSF) can then leak into the
nose. What results is a watery, salty fluid leaking from the nose,
especially with exertion or straining.
This condition is considered
dangerous because the opening between the brain and the sinuses
gives bacteria from the nose access into the critical brain area.
This can result in meningitis, or infection of the lining of the
leaks can occur spontaneously or can be the result of trauma, most
often car accidents.
Formerly, closure of
such leaks involved a craniotomy, or surgical operation involving
opening of the skull and brain cavity.
The recent advances
that have been made in endoscopic sinus techniques now allow repair
of this problem through the nose without the need for facial or
surgical operation involving opening of the skull and brain cavity.
of Cerebrospinal Fluid leaks can be achieved in greater than 90%
of cases using this approach.
