DEFINITION
Earache (otalgia) is a common complaint in the pediatric population (see table Common Causes of Earache). Primary otalgia refers to pain originating from the ear structures. Secondary otalgia arises from referred pain from other areas of the head and neck. Secondary pain is referred through cranial and cervical nerves that share distributions with the ear.

GENERAL GOALS
Because ear pain arises from a large number of sites, history taking and physical examination should be directed toward assessing symptoms from the entire region, not just the ear (face, oropharynx, larynx, and neck). Preverbal children and children with language delay may present with non-specific symptoms (fever, fussiness, tugging at ears, lethargy, vomiting) that should alert one to consider the possibility of ear pain as the source of the problem.
Phase 1: Each encounter should begin with a careful history and physical examination. The following sections suggest questions that may be helpful, as well as potentially significant physical exam findings. If the examination of the ear does not reveal the cause of pain, thoroughly examine the entire head and neck region.
Phase 2: An abnormal audiogram or tympanogram may help to determine if ear pathology is present in the face of a normal physical exam. Lateral neck films may be helpful in evaluation of a suspected retropharyngeal process. Other laboratory and radiologic evaluations must be guided by your suspicions based on your history and physical.
Phase 3: Referral to an otorhinolaryngologist is indicated in cases of ear pain with no identifiable cause.
| DATA GATHERING | ||
HISTORY
Question: Duration of symptoms?
Significance: Acute onset
more likely suggests recent trauma or infection.
Question: Location?
Significance: If referred pain, will
likely have symptoms at primary site as well.
Question: Fever?
Significance: Suggestive of infectious
etiology.
Question: Trauma?
Significance: Ask about recent ear
cleaning, falls, accidents, etc.
Question: History of recurrent otitis media?
Significance:
Consider serous otitis media, cholesteatoma.
Question: Tinnitus?
Significance: May represent otitis media
with effusion, inner ear abnormalities, vascular lesions or tumors.
Question: Ear drainage?
Significance: Look for primary
source such as otitis media with perforation, cholesteatoma, otitis externa, and
trauma.
Question: Vertigo?
Significance: Again a primary source from
the external, middle, or inner ear is the likely cause, although CNS pathology
must be a consideration.
Question: Hearing loss?
Significance: Suggestive of primary
problem; however, can be associated with intracranial lesion and multiple other
syndromes and diseases.
Question: Hoarseness?
Significance: Suggestive of
oropharyngeal or laryngeal pathology including infections, foreign body, and
GER.
Question: Drooling?
Significance: Suggestive of
oropharyngeal or laryngeal pathology particularly infections, foreign bodies,
and caustic ingestion.
Question: Stridor?
Significance: Suggestive of oropharyngeal
or laryngeal pathology, which causes airway narrowing. Consider infections,
foreign body, mass.
Question: Choking/coughing?
Significance: Consider foreign
body, mass, or GER.
| PHYSICAL EXAMINATION | ||
Finding: Intense pain elicited by traction on
pinna.
Significance: Suggestive of otitis externa
Finding: Areas of trauma
Significance: There may be an
isolated abrasion or laceration; however, inspect carefully for hemotympanum and
associated injuries and evidence of basilar skull fracture.
Finding: Foreign bodies
Significance: May be isolated, or
associated with otitis externa
Finding: Bulging, red, immobile tympanic
membrane
Significance: Consistent with otitis media
Finding: Retracted, immobile tympanic membrane
Significance:
Suggests otitis media with effusion
Finding: Evidence of a mass lesion
Significance: A mass
lesion behind the tympanic membrane may represent a cholesteatoma, although
other benign and malignant lesions must be considered.
Finding: Neck oropharynx, TMJ, lymph nodes, salivary glands, and
neck
Significance: If no findings suggest a primary source, inspect
each area carefully for signs of secondary pathology.
Finding: Dental caries
Significance: Multiple dental caries
should raise the suspicion of a possible dental abscess.
Finding: Tonsillar asymmetry or uvular deviation from
midline
Significance: May represent peritonsillar cellulitis/abscess
or mass.
Finding: Trismus, drooling
Significance: May represent a
mass/abscess
Finding: Assess facial-nerve function and other cranial
nerves
Significance: Bell palsy may be a complication of otitis media.
Other cranial nerve dysfunction suggests possible intracranial
lesion.
| LABORATORY AIDS | ||
The history and physical examination are usually enough to make a diagnosis.
Test: Audiometry
Significance: Assess for hearing loss
suggestive of primary otalgia
Test: Tympanometry
Significance: Useful in assessment of
otitis media with effusion, eustachian-tube dysfunction, and tympanostomy tube
obstruction
Test: Lateral neck x-ray studies
Significance: Helpful for
symptoms suggestive of retropharyngeal mass/abscess.
Test: Imaging of head
Significance: Rarely needed unless
intracranial lesion suspected
Test: Blood screens
Significance: Not routinely
useful
