otitis media

decreased mobility of the eardrum. Children with OME may have up to a
30- to 40-decibel (dB) conductive hearing loss, which in some studies
affected speech development and learning
. Antibiotic therapy is not usu-
ally indicated for children with OME. Patients with OME are sometimes
treated with a short course of oral or topical nasal steroids, to
decrease the
swelling
in the eustachian tube and
allow ventilation of the middle ear
space
. Referral to an otolaryngologist should be considered for children
with at least three months of persistent middle ear effusion. Placement of
PE tubes is often entertained for such children whose effusions are associ-
ated with hearing loss.
An
adenoidectomy,
or removal of the adenoid tissue in the nasopharynx,
has been shown to reduce the need for PE tubes in children, presumably
by removing a focus of eustachian tube inflammation. Adenoidectomy is
often recommended if a child requires a second set of PE tubes, or with
the first set of tubes if the child has significant nasal symptoms. Children
usually grow out of the need for the tubes as they get older, as the eusta-
chian tube assumes a longer and more downward-slanted course with
time. However, there are certain subsets of patients, such as children with
a history of cleft palate or trisomy 21, who can have long-term problems
with otitis
media
and eustachian tube dysfunction.
OME in an adult
, especially if it is
of recent origin and unilateral
, should
prompt an examination of the nasopharynx for a disease process affecting
the eustachian tube
. Early nasopharyngeal carcinoma
is well known for
its silent nature—often the only sign is unilateral OME. Later in the disease
process, the tumor
metastasizes
to the cervical lymph nodes and extends
into the skull base, causing
cranial neuropathies
. In the past, nasopharyn-
geal examination was performed with mirrors, but most otolaryngologists
now routinely use rigid or flexible endoscopic instrumentation.
Complications of Acute Otitis Media
Complications of acute otitis media were common in the pre-antibiotic
era. It is largely because of those complications that otolaryngology devel-
oped as a specialty more than 100 years ago. With advances in the diagno-
sis and treatment of otitis media, such complications as
mastoiditis
and
meningitis
have decreased in incidence. However,
as the prevalence of
resistant organisms increases
, especially
Streptococcus pneumoniae
, there
is a chance that
these complications may again become more common
.
Therefore, even if you never see a case during your medical school years,
you must know about these complications and be able to recognize them
if you encounter them in your practice. If untreated, acute otitis media can
