Overview

Ear pain or otalgia maybe it is the pain that originates outside the ear or the pain that originates from the ear and the etiology can be difficult to establish because of the complex innervation of the ear.otalgia classified as primary which originated from the ear, and secondary which originated outside the ear. When the ear examination is abnormal, the source of the pain from the ear (primary otalgia). When the ear examination is typically normal, the source of the pain is not the ear(secondary otalgia).

Causes

Life Threatening Causes

Otalgia is not life-threatening, but some characteristics make a serious diagnosis more likely in patients with Otalgia. As patients who are 50 years or older, have coronary artery disease, have diabetes, or are immunocompromised are at higher risk. Also, patients who smoke, drink alcohol, or lose weight unintentionally should undergo more scrutiny.Otalgia may also be the first sign of:-

• temporal arteritis
• Myocardial infarction
• Thoracic aneurysms
• subdural hematoma
• lung cancer
• central line placement
• carotid artery aneurysm
• Pott puffy tumor
• malignant neoplasms

Common Causes

Common causes for Primary Otalgia

• Otitis media
• Otitis externa
• Barotrauma
• Eustachian tube dysfunction
• Foreign object
• Cellulitis of auricle
• Cholesteatoma

Common causes for Secondary Otalgia

• Bell palsy
• Carotidynia
• Cervical adenopathy
• Cervical spine arthritis
• Cricoarytenoid arthritis
• Dental infections
• Gastroesophageal reflux
• Head and neck tumors
• Temporomandibular joint syndrome
• Myofascial pain
• Neuralgias (trigeminal, glossopharyngeal, geniculate, sphenopalatine)
• Oral aphthous ulcers
• Pharyngitis or tonsillitis
• Salivary gland disorders
• Sinusitis
• thyroiditis

Diagnosis

Shown below is an algorithm summarizing the diagnosis of Ear pain according to the American Family Physician AFP 2008 guidelines.

patient present with history of ear pain Pain (factors should be considered location, duration, aggravating factors, alleviating factors, associated symptoms, previous episodes, medical history, smoking status, and alcohol abuse.) Symptoms of primary otalgia such as - Otorrhea Tympanic membrane fullness Vertigo Symptoms of secondary otalgia Pain with chewing Sinusitis Dental procedures A history of gastroesophageal reflux. No hearing loss

ear examination include:- inspection of the auricle and periauricular region otoscopic examination, which may require cerumen removal.

abnormal findings with apperant the causes identified( primary otalgia)

normal or equivocal findings

Treat underlying cause

more evaluation and examine nose, throat, neck, chest(consider audiometry,tympanometry,pneumetic otoscopy)

dental etiology

temporomandibular joint syndrome

Dental referral

pain killer as primary care and soft diet if the pain presistent, refer to dental care

HX of smoking, alcohol use, age older than 50 years,

Coronary artery disease risk factors

HX of headache, malaise, wight loss, fever, or anorexia and age older than 50 years

No risk factors of serious diagnosis

more evaluation by nasolaryngoscopy, tympanometry, audiometry,or magnetic resonance imaging,and computed tomography (if there is a history of cancer, positron emission tomography may be performed to provide)

ECG,chest radiography ,troponin maeseurment

ESR reat

Otolaryngology referral

send to emergency department

depends on the rate of patient more than 50mm per hour immedate otolaryngology or ophthalmology consultation

Observe or treat empirically as pain killer, soft diet if pain presistent more evaluation and refer

Treatment

Shown below is an algorithm summarizing the treatment of Ear pain according the the American Family Phsyician guidelines.

patient with ear pain

Infection treat with antibiotics topical or systemic, cleaning of the area, and oral analgesics for comfort

referred ear pain

If no responsed refered to evaluation by otorhinolaryngology, IV antibiotics, and hospital admission.

There is procedural management by a health professional, in addition to antibiotic therapy as:- Removal of impacted desquamated keratin debris in the ear canal in case Keratosis obturans. Surgical debridement, Surgical drainage could be required in case of Chronic perichondritis. When the development of bullae on the tympanic membrane can be punctured to give pain relief. Foreign bodies in the ear canal can cause pain and be treated with careful removal. Infected sebaceous cyst is treated with incision and drainage of the cysts, oral antibiotics, and otorhinolaryngology assessment.
