Classified as : Otogenic or Primary otalgia: is the pain that originates by a disease within the ear. Referred or secondary otalgia: is the pain that originates by a disease outside the ear.

ACUTE OTITIS MEDIA
OTITIC BAROTRAUMA Pain onset during descent of airplane or while diving Non suppurative condition due to failure of Eustachian tube to maintain middle ear pressure at ambient atmospheric level Mechanism When atmospheric pressure is higher than middle ear pressure Eustachian tube gets locked.- - ve pressure in middle ear - retraction of tympanic membrane- hyperaemia,transudation and haemorrhage in the middle ear.
Clinical features Severe earache ,hearing loss,tinnitus Tm retracted ,congested or ruptured Hemotympanum Treatment Nasal decongestants Antihistamines Myringotomy Prevention Swallow during descent Do not sleep during descent Auto inflation of tube by valsalva during descent. OTITIC BAROTRAUMA
MYRINGITIS BULLOSA Painful condition occurring spontaneously and resolving within several days . Vesicular eruption is seen on the tympanic membrane which maybe associated with bleeding or serous discharge . Probably caused by virus or mycoplasma pneumonia
Inflammation of mucosal lining of antrum and mastoid air cell system. Follow acute suppurative otitis media Clinical Features: Pain behind the ear Fever Ear Discharge Mastoid tenderness Sagging of posterosuperior meatal wall Swelling over the mastoid Deafness ACUTE MASTOIDITIS
Management : Hospitalization Antibiotics Myringotomy Pus under tension not resolving with medical therapy Cortical Mastoidectomy Subpreiosteal abscess Positive reservoir sign No change in symptoms after 48 hrs of medical management Complications Facial palsy, labrynthitis,intracranial complications. ACUTE MASTOIDITIS
REFERRED PAIN is an unpleasant sensation localized to an area separate from the site of the causative injury or other noxious stimulus
REFERRED PAIN Often, referred pain is caused by nerve compression or irritation. In this circumstance, the sensation of pain will generally be felt in the territory that the nerve serves ( ie,somatic dermatome) even though the damage originates elsewhere ( ie,visceral tissue).
When to label as referred otalgia ? CLINICALLY NORMAL Pinna External auditory meatus Tympanic membrane Mastoid process
WARNING Referred earache may be a presenting symptom of head and neck cancer
Referred otalgia Common causes : Dental causes(caries ,abscess ,impacted teeth) TMJ dysfunction Tonsillitis and pharyngitis Cervical spine arthritis
Referred otalgia Uncommon cause : Tumors (hypopharynx ,larynx ,base of the tongue ,nassopharynx ,parotid ,esophagus ) Neuralgias (trigeminal ,glossopharyngeal ,geniculate ) Temporal arteritis Oral ulcers Eagles syndrome
Referred otalgia Uncommon cause : Sinusitis /Nasal polyps Thyroiditis Parotid gland disorders(mumps ,stone ) GERD Myocardial ischemia Psychogenic otalgia
Referred otalgia Ear pain can be referred to the ears in five main ways.
TMJ dysfunction Caused by : (joint dislocation ,arthritis ) clinical features : pain around the TMJ Trismus Joint sound or crepitus Tenderness of the joint or associated muscle Management : Rest Soft diet Moist heat and massage NSAIDS Muscle relaxant Consultation with oral surgeon
Oral ulcers Recurrent aphthous ulcer is commonest oral ulcer Other causes include trauma ,nutritional deficiency ,Behcets syndrome and autoimmune disorders Painful locally ,earache
Throat infection Tonsillitis is one of the commonest cause of referred otalgia . Post-tonsillectomy referred pain less severe in children than adult . Peritonsiller ,retropharyngeal ,Parapharyngeal abscess will cause earache too Sore throat ,fever ,trismus ,odynophagia are associated symptoms with ear ache
Tumors Parotid ,hypopharynx ,nassophayrynx ,base of tongue ,larynx and cervical spine Risk factors include smoking ,alcohol use ,age older than 50 years,radiation exposure Associated symptom ( hoarsness, dysphagia,nasal blockage ,weight loss )
NEURALGIAS Trigeminal ,glossopharyngeal and geniculate (intermedius) neuralgia Pain usually brief (seconds) in their sensory distribution area Severe, lancing ,electric – shock- like pain May have trigger point
Eagles syndrome It is an elongation of the styloid process Cause deep ,unremitting pain exacerbated by swallowing ,yawning ,foreign body sensation in throat . Treated by surgical excision via trans-oral approach or lateral approach .
Cervical spine arthritis Cause crepitus or neck and ear pain with neck movements Decreased neck range of motion ,tender spinous processes or Para-spinal muscles Pain referred to ear from C2,C3 cervical nerve root
PSYCHOGENIC OTALGIA when no cause to the pain in ears can be found, it suggest a functional origin. The patient in such cases should be kept under observation with periodic re-evaluation.
EVALUATION OF OTALGIA History Ear symptoms Nasal symptoms swallowing disorders recent trauma General Symptoms Examination General physical examination Complete ENT examination Rhinoscopy , nasopharyngoscopy , and indirect laryngoscopy. Palpation of the neck is important to look for thyroid disease and 1lymphadenopathy
DIAGNOSTIC TEST CBC ,ESR PTA TYMPANOMETRY Pneumatic otoscopy X- ray FIBEROPTIC NASOPHARYNGOSCOP Barium swallow Indirect laryngoscopy CT scan MRI with gadolinium Biopsy Diagnostic anesthetic blocks and pharyngeal cocainization
