Study Notes

Causes of Otalgia

Primary otalgia is most commonly caused by ear infections or conditions affecting the ear.
Secondary causes may include dental issues, throat infections, and referred pain from other regions like the neck.
Common causes of referred otalgia include cervical disc disease and throat disorders.

Frequency and Consultation

A notable percentage of general practitioner encounters are solely focused on ear-related issues.
Outpatient specialist referral for otalgia is indicated when symptoms persist despite standard treatment.

Ear Anatomy and Function

Major anatomical structures of the external ear include the pinna, auditory canal, and tympanic membrane.
The eustachian tube functions to equalize pressure between the middle ear and the atmosphere.

Pain and Diagnostics

Pain referred to the ear via cranial nerves is known as referred otalgia.
Key finding in acute otitis media (AOM) includes bulging or redness of the tympanic membrane.
Pain on insertion of the otoscope indicates potential ear infections or inflammation.

Oropharyngeal Examination

Examining the oropharynx in patients with otalgia is crucial since it may reveal underlying neoplasms or infections.
Risk factors for cancers in the oropharyngeal region include smoking and HPV infection.
A symptom NOT typically associated with oropharyngeal neoplasms should be identified for accurate assessment.

Red Flags and Complications

Red flag history points for otalgia include severe pain, persistent symptoms, or otorrhea.
Key findings in acute mastoiditis may involve fever and postauricular swelling, indicating a more severe complication.

Investigations and Management

Ear swabs should be performed when there are clear signs of infection or when cultures are necessary for diagnosis.
Recommended investigation for patients with hearing loss includes audiometry testing.
If a diagnosis is unclear or the condition does not improve, further imaging or specialist referral may be warranted.

Other Conditions

Symptoms of Herpes zoster oticus (Ramsay Hunt syndrome) include ear pain, rash in the ear canal, and facial paralysis.
In atypical cases, referral to a dental or maxillofacial specialist may be necessary to rule out odontogenic sources of pain.

Treatment Approach

Management of otalgia often includes analgesia to relieve pain and enhance patient comfort during evaluation and treatment.
A straightforward algorithm exists for assessing otalgia, incorporating history taking, physical examination, and targeted investigations.

Key Findings for Clinician Assessment

Cranial nerves supplying sensation to the ear include the trigeminal and facial nerves.
Differentiating between severe otalgia with a history of otitis externa involves considering other possible complications or associated conditions.
