The Three Ps Of Ear Disease
> Primary cause of ear disease needs to be identified and can
include:
 Parasites
 Allergies (most common cause)
 Foreign bodies
 Scaling disorders
 Other dermatological diseases
> Predisposing factors are those that directly change the
microclimate of the ear canal
> Perpetuating factors that prevent normal resolution of ear
disease, e.g.
 Bacteria
 Yeasts
 Secretions from otitis media
 Contact allergies from drugs

The 4 Step Approach To Otitis Externa
1. Examine the skin and ears

Check the skin to identify potential primary causes of
the ear disease
 Exam the ear canal
for exudates,
growths or other
pathological changes
 Always evaluate the
the integrity of the
eardrum as this
impacts the choices
of medications &
flushing agents

2. Cytological Evaluation
of the otic exudate of
every infected ear to
determine potential
etiology

3. Flush and suction the ears to remove
dried medications and exudates so that
the canal epithelium can be evaluated.

Be sure the flushing
agent is not ototoxic
when the eardrum is
not intact.

4. Develop a treatment plan for otitis
externa after the skin and ears are
evaluated, the cytology is done and the
ear canal is cleansed
