A new device for treating fluid in the middle ear
The presence
of fluid in the middle ear without signs or symptoms of acute ear infection is
called middle ear effusion (MEE). It is also one of the most
common reasons why children visit the doctor. In approximately 90 percent of cases,
the fluid disappears spontaneously within a few months. But when the fluid persists,
it can adversely affect a child's hearing.
Current treatments, including antibiotics,
decongestants and antihistamines, have not always been very successful in eliminating the
fluid. If the MEE persists, or if there is a conductive hearing loss, an incision
on the ear drum, with or without placement of an ear ventilation tube, may
be indicated.
A new device that might help
There might be another option, however, a device known as an
EarPopper.™ Developed by Daniel Arick, MD, an otolaryngologist at New York Eye
and Ear Infirmary in Brooklyn, and Shlomo Silman, PhD, an audiologist, the
device involves forcing air under pressure through the nose into a naturally
occurring passage at the back of the nose (the eustachian tube) and into the
middle ear system. Theoretically, this allows opening of the eustachian tube,
normalization of pressure in the ear and elimination of MEE.
Here's how it works: the device delivers a constant flow
of air into the nose. The patient then swallows while the device is running.
During the act of swallowing the air is diverted up the eustachian tube,
clearing and ventilating the middle ear. The EarPopper™ may be used with
patients ages four and up. However, it should not
be used during acute ear infections.
One study shows good results thus far
In a four-year study sponsored by the National Institutes of
Health, Arick and Silman tested the device in a total of 47 children and
compared the results to 47 children who were observed without any medical
intervention. Seventy-four percent of children who were treated twice a day for
seven weeks with the EarPopper™ had restoration of their hearing compared to 27
percent of children who received no treatment. After extending the treatment for
four weeks in patients who did not recover within the first seven weeks, the
total recovery for the study group was 85 percent. According to Dr. Arick, there
were no complications during the study involving ear drum rupture or acute ear
infections.
Dr. John
Maddalozzo was among the physicians in
Children's Memorial Hospital's Division
of Otolaryngology who tested the device, which
is available by prescription only, and found it simple to use. Treatment only
took seconds to perform and was not painful. In their view, the EarPopper™
appears promising, however, long-term effects and efficacy in larger groups have
yet to be studied.
