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.

APPROACH TO THE PATIENT

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

EMERGENCY CARE

Disorders with potential to cause airway compromise (mass lesions, foreign bodies, abscess, etc.):

Trauma resulting in hearing loss, significant bleeding, or fractures:

Infectious etiologies that cause toxic-appearing or “septic” child:

Issues for Referral

Factors that may alert you to make a referral to an ORL include:
