Earache: Medical causes
(Handbook of Signs & Symptoms (Third Edition))

Abscess (extradural)

Severe earache accompanied by a persistent ipsilateral headache, malaise, and a recurrent mild fever characterizes an abscess, which is a serious complication of middle ear infection.

Barotrauma (acute)

Earache associated with barotrauma ranges from mild pressure to severe pain. Tympanic membrane ecchymosis or bleeding into the tympanic cavity may occur, producing a blue drumhead; the eardrum usually isn't perforated.

Cerumen impaction

Impacted cerumen (earwax) may cause a sensation of blockage or fullness in the ear. Additional features include partial hearing loss, itching and, possibly, dizziness.

Herpes zoster oticus (Ramsay Hunt syndrome)

Herpes zoster oticus causes burning or stabbing ear pain, commonly associated with ear vesicles. The patient also complains of hearing loss and vertigo. Associated signs and symptoms include transitory, ipsilateral, facial paralysis; partial loss of taste; tongue vesicles; and nausea and vomiting.

Keratosis obturans

Mild ear pain is common with keratosis obturans, along with otorrhea and tinnitus. Inspection reveals a white glistening plug obstructing the external meatus.

Mastoiditis (acute)

Mastoiditiscauses a dull ache behind the ear accompanied by a low-grade fever (99 to 100 F [37.2 to 37.87 C]). The eardrum appears dull and edematous and may perforate, and soft tissue near the eardrum may sag. A purulent discharge is seen in the external canal.

Ménière's disease

Ménière's disease is an inner ear disorder that can produce a sensation of fullness in the affected ear. Its classic effects, however, include severe vertigo, tinnitus, and sensorineural hearing loss. The patient may also experience nausea and vomiting, diaphoresis, and nystagmus.

Otitis externa

Earache characterizes acute and malignant otitis externa. Acute otitis externa begins with mild to moderate ear pain that occurs with tragus manipulation. The pain may be accompanied by a low-grade fever, sticky yellow or purulent ear discharge, partial hearing loss, and a feeling of blockage. Later, ear pain intensifies, causing the entire side of the head to ache and throb. Fever may reach 104 F (40 C). Examination reveals swelling of the tragus, external meatus, and external canal; eardrum erythema; and lymphadenopathy. The patient also complains of dizziness and malaise.

Malignant otitis externa abruptly causes ear pain that's aggravated by moving the auricle or tragus. The pain is accompanied by intense itching, purulent ear discharge, a fever, parotid gland swelling, and trismus. Examination reveals a swollen external canal with exposed cartilage and temporal bone. Cranial nerve palsy may occur.

Otitis media (acute)

Otitis media is middle ear inflammation that may be serous or suppurative. Acute serous otitis media may cause a feeling of fullness in the ear, hearing loss, and a vague sensation of top-heaviness. The eardrum may be slightly retracted, amber, and marked by air bubbles and a meniscus, or it may be blue-black from hemorrhage.

Severe, deep, throbbing ear pain; hearing loss; and a fever that may reach 102 F (38.9 C) characterize acute suppurative otitis media.

The pain increases steadily over several hours or days and may be aggravated by pressure on the mastoid antrum. Perforation of the eardrum is possible. Before rupture, the eardrum appears bulging and fiery red. Rupture causes purulent drainage and relieves the pain.

Chronic otitis media usually isn't painful except during exacerbations. Persistent pain and discharge from the ear suggest osteomyelitis of the skull base or cancer.

Vertigo: Medical causes
(Handbook of Signs & Symptoms (Third Edition))

Acoustic neuroma

Acoustic neuroma is a tumor of the eighth cranial nerve that causes mild, intermittent vertigo and unilateral sensorineural hearing loss. Other findings include tinnitus, postauricular or suboccipital pain, and — with cranial nerve compression — facial paralysis.

Benign positional vertigo

With benign positional vertigo, debris in a semicircular canal produces vertigo on head position change, which lasts a few minutes. It’s usually temporary and can be effectively treated with positional maneuvers.

Brain stem ischemia

Brain stem ischemia produces sudden, severe vertigo that may become episodic and later persistent. Associated findings include ataxia, nausea, vomiting, increased blood pressure, tachycardia, nystagmus, and lateral deviation of the eyes toward the side of the lesion. Hemiparesis and paresthesia may also occur.

Head trauma

Persistent vertigo, occurring soon after injury, accompanies spontaneous or positional nystagmus and, if the temporal bone is fractured, hearing loss. Associated findings include headache, nausea, vomiting, and decreased (LOC). Behavioral changes, diplopia or visual blurring, seizures, motor or sensory deficits, and signs of increased intracranial pressure may also occur.

Herpes zoster

Infection of the eighth cranial nerve produces sudden onset of vertigo accompanied by facial paralysis, hearing loss in the affected ear, and herpetic vesicular lesions in the auditory canal.

Labyrinthitis

Severe vertigo begins abruptly with labyrinthitis, an inner ear infection. Vertigo may occur in a single episode or may recur over months or years. Associated findings include nausea, vomiting, progressive sensorineural hearing loss, and nystagmus.

Ménière’s disease

With Ménière’s disease, labyrinthine dysfunction causes abrupt onset of vertigo, lasting minutes, hours, or days. Unpredictable episodes of severe vertigo and unsteady gait may cause the patient to fall. During an attack, any sudden motion of the head or eyes can precipitate nausea and vomiting.

Multiple sclerosis (MS)

Episodic vertigo may occur early and become persistent. Other early findings include diplopia, visual blurring, and paresthesia. MS may also produce nystagmus, constipation, muscle weakness, paralysis, spasticity, hyperreflexia, intention tremor, and ataxia.

Seizures

Temporal lobe seizures may produce vertigo, usually associated with other symptoms of partial complex seizures.

Vestibular neuritis

With vestibular neuritis, severe vertigo usually begins abruptly and lasts several days, without tinnitus or hearing loss. Other findings include nausea, vomiting, and nystagmus.

Other causes

Diagnostic tests

Caloric testing (irrigating the ears with warm or cold water) can induce vertigo.

Drugs and alcohol

High or toxic doses of certain drugs or alcohol may produce vertigo. These drugs include salicylates, aminoglycosides, antibiotics, quinine, and hormonal contraceptives.

Surgery and other procedures

Ear surgery may cause vertigo that lasts for several days. Also, administration of overly warm or cold eardrops or irrigating solutions can cause vertigo.

Ménière's disease: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

The exact cause of Ménière’s disease is unknown. It may result from overproduction or decreased absorption of endolymph, which causes endolymphatic hydrops or endolymphatic hypertension, with consequent degeneration of the vestibular and cochlear hair cells. This condition may also stem from autonomic nervous system dysfunction that produces a temporary constriction of blood vessels supplying the inner ear. In some cases, Ménière’s disease may be related to otitis media, syphilis, or head injury. Risk factors include recent viral illness, respiratory infection, stress, fatigue, use of prescription or nonprescription drugs (such as aspirin), and a history of allergies, smoking, and alcohol use. There also may be genetic risk factors: In some women, premenstrual edema may precipitate attacks of Ménière’s disease.

In the United States, about 100,000 people per year develop Ménière’s disease.

Barotrauma (acute)

Earache associated with barotrauma ranges from mild pressure to severe pain. Tympanic membrane ecchymosis or bleeding into the tympanic cavity may occur, producing a blue drumhead; the eardrum usually isn’t perforated.

Cerumen impaction

Impacted cerumen (earwax) may cause a sensation of blockage or fullness in the ear. Additional features include partial hearing loss, itching and, possibly, dizziness.

Chondrodermatitis nodularis chronica

Chondrodermatitis nodularis chronica produces small, painful, indurated areas along the auricle’s upper rim.

Ear canal obstruction by an insect

An insect lodged in the ear canal may cause severe pain and distressing noise.

Frostbite

Prolonged exposure to cold may cause burning or tingling pain in the ear, followed by numbness. The ear appears mottled and gray or white; it turns purplish blue as it’s warmed.

Furunculosis

Infected hair follicles in the outer ear canal may produce severe, localized ear pain associated with a pus-filled furuncle (boil). The pain is aggravated by jaw movement and relieved by rupture or incision of the furuncle. Pinna tenderness, swelling of the auditory meatus, partial hearing loss, and a feeling of fullness in the ear canal may also occur.

Herpes zoster oticus (Ramsay Hunt syndrome)

Herpes zoster oticus causes burning or stabbing ear pain that’s commonly associated with ear vesicles. The patient also complains of hearing loss and vertigo. Associated signs and symptoms include transient ipsilateral facial paralysis, partial loss of taste, tongue vesicles, and nausea and vomiting.

Keratosis obturans

Mild ear pain, otorrhea, and tinnitus are common in keratosis obturans. Inspection reveals a white glistening plug obstructing the external meatus.

Mastoiditis (acute)

Mastoiditis causes a dull ache behind the ear accompanied by low-grade fever (99° F to 100° F [37.2° C to 37.8° C]). The eardrum appears dull and edematous and may perforate, and soft tissue near the eardrum may sag. A purulent discharge is seen in the external canal.

Ménière’s disease

Ménière’s disease is an inner ear disorder that can produce a sensation of fullness in the affected ear. Its classic effects, however, include severe vertigo, tinnitus, and sensorineural hearing loss. The patient may also experience nausea and vomiting, diaphoresis, and nystagmus.

Middle ear tumor

Deep, boring ear pain and facial paralysis are late signs of a malignant tumor.

Myringitis bullosa

Myringitis bullosa is a rare bacterial infection that causes sudden, severe ear pain that radiates over the mastoid and lasts for up to 48 hours. Small serous or blood-filled vesicles may dot the reddened tympanic membrane. Transient hearing loss and a serosanguineous discharge may also occur.

Otitis externa

Earache characterizes both acute and malignant otitis externa. Acute otitis externa begins with mild to moderate ear pain that occurs with tragus manipulation. The pain may be accompanied by low-grade fever, sticky yellow or purulent ear discharge, partial hearing loss, and a feeling of blockage. Later, ear pain intensifies, causing the entire side of the head to ache and throb. Fever may reach 104° F (40° C). Examination reveals swelling of the tragus, external meatus, and external canal; eardrum erythema; and lymphadenopathy. The patient also complains of dizziness and malaise.

Malignant otitis externa causes sudden ear pain that’s aggravated by moving the auricle or tragus. The pain is accompanied by intense itching, purulent ear discharge, fever, parotid gland swelling, and trismus. Examination reveals a swollen external canal with exposed cartilage and temporal bone. Cranial nerve palsy may occur.

Otitis media (acute)

Otitis media is a middle ear inflammation that can be serous or suppurative. Acute serous otitis media may cause a feeling of fullness in the ear, hearing loss, and a vague sensation of top-heaviness. The eardrum may be slightly retracted, amber colored, and marked by air bubbles and a meniscus, or it may be blue-black from hemorrhage.

Acute suppurative otitis media is characterized by severe deep, throbbing ear pain; hearing loss; and fever that may reach 102° F (38.9° C).The pain increases steadily over several hours or days and may be aggravated by pressure on the mastoid antrum. Perforation of the eardrum is possible. Before rupture, the eardrum appears bulging and fiery red. Rupture causes purulent drainage and relieves the pain.

Chronic otitis media usually isn’t painful except during exacerbations. Persistent pain and discharge from the ear suggest cancer or osteomyelitis of the skull base.

Perichondritis

Perichondritis can cause ear pain accompanied by warmth and tenderness in the outer ear and a reddened, doughlike auricle.

Petrositis

The result of acute otitis media, this infection produces deep ear pain with headache and pain behind the eye. Other findings are diplopia, loss of lateral gaze, vomiting, sensorineural hearing loss, vertigo and, possibly, nuchal rigidity.

Temporomandibular joint infection

Typically unilateral, temporomandibular joint infection produces ear pain that’s referred from the jaw joint. The pain is aggravated by pressure on the joint with jaw movement; it commonly radiates to the temporal area or the entire side of the head.

Earache [Otalgia]: Medical causes
(Nursing: Interpreting Signs and Symptoms)

Abscess (extradural).Severe earache accompanied by a persistent ipsilateral headache, malaise, and a recurrent mild fever characterizes an abscess, which is a serious complication of middle ear infection.

Barotrauma (acute).Earache associated with barotrauma ranges from mild pressure to severe pain. Tympanic membrane ecchymosis or bleeding into the tympanic cavity may occur, producing a blue drumhead; the eardrum usually isn't perforated.

Cerumen impaction.Impacted cerumen (earwax) may cause a sensation of blockage or fullness in the ear. Additional features include partial hearing loss, itching and, possibly, dizziness.

Herpes zoster oticus (Ramsay Hunt syndrome).Herpes zoster oticus causes burning or stabbing ear pain, commonly associated with ear vesicles. The patient also complains of hearing loss and vertigo. Associated signs and symptoms include transitory, ipsilateral, facial paralysis; partial loss of taste; tongue vesicles; and nausea and vomiting.

Keratosis obturans.Mild ear pain is common with keratosis obturans, along with otorrhea and tinnitus. Inspection reveals a white glistening plug obstructing the external meatus.

Mastoiditis (acute).Mastoiditis causes a dull ache behind the ear accompanied by a low-grade fever (99° to 100° F [37.2° to 37.8° C]). The eardrum appears dull and edematous and may perforate, and soft tissue near the eardrum may sag. A purulent discharge is seen in the external canal.

Ménière's disease.Ménière's disease is an inner ear disorder that can produce a sensation of fullness in the affected ear. Its classic effects, however, include severe vertigo, tinnitus, and sensorineural hearing loss. The patient may also experience nausea and vomiting, diaphoresis, and nystagmus.

Otitis externa.An earache characterizes acute and malignant otitis externa. Acute otitis externa begins with mild to moderate ear pain that occurs with tragus manipulation. The pain may be accompanied by a low-grade fever, sticky yellow or purulent ear discharge, partial hearing loss, and a feeling of blockage. Later, ear pain intensifies, causing the entire side of the head to ache and throb. Fever may reach 104° F (40° C). Examination reveals swelling of the tragus, external meatus, and external canal; eardrum erythema; and lymphadenopathy. The patient also complains of dizziness and malaise.

Malignant otitis externa abruptly causes ear pain that's aggravated by moving the auricle or tragus. The pain is accompanied by intense itching, purulent ear discharge, a fever, parotid gland swelling, and trismus. Examination reveals a swollen external canal with exposed cartilage and temporal bone. Cranial nerve palsy may occur.

Otitis media (acute).Otitis media is middle ear inflammation that may be serous or suppurative. Acute serous otitis media may cause a feeling of fullness in the ear, hearing loss, and a vague sensation of top-heaviness. The eardrum may be slightly retracted, amber, and marked by air bubbles and a meniscus, or it may be blue-black from hemorrhage.

Severe, deep, throbbing ear pain; hearing loss; and a fever that may reach 102° F (38.9° C) characterize acute suppurative otitis media. The pain increases steadily over several hours or days and may be aggravated by pressure on the mastoid antrum. Perforation of the eardrum is possible. Before rupture, the eardrum appears bulging and fiery red. Rupture causes purulent drainage and relieves the pain.

Chronic otitis media usually isn't painful except during exacerbations. Persistent pain and discharge from the ear suggest osteomyelitis of the skull base or cancer.

Vertigo: Medical causes
(Nursing: Interpreting Signs and Symptoms)

Acoustic neuroma.Acoustic neuroma causes mild, intermittent vertigo and unilateral sensorineural hearing loss. Other findings include tinnitus, postauricular or suboccipital pain, and—with cranial nerve compression—facial paralysis.

Benign positional vertigo.With benign positional vertigo, debris in a semicircular canal produces vertigo with head position change, which lasts a few minutes. It's usually temporary and can be effectively treated with positional maneuvers.

Brain stem ischemia.Brain stem ischemia produces sudden, severe vertigo that may become episodic and later persistent. Associated findings include ataxia, nausea, vomiting, increased blood pressure, tachycardia, nystagmus, and lateral deviation of the eyes toward the side of the lesion. Hemiparesis and paresthesia may also occur.

Head trauma.Persistent vertigo, occurring soon after head injury, accompanies spontaneous or positional nystagmus and, if the temporal bone is fractured, hearing loss. Associated findings include headache, nausea, vomiting, and decreased (LOC). Behavioral changes, diplopia or visual blurring, seizures, motor or sensory deficits, and signs of increased intracranial pressure may also occur.

Herpes zoster.Herpes infection of the eighth cranial nerve produces sudden onset of vertigo accompanied by facial paralysis, hearing loss in the affected ear, and herpetic vesicular lesions in the auditory canal.

Labyrinthitis.Severe vertigo begins abruptly with labyrinthitis. Vertigo may occur in a single episode or may recur over months or years. Associated findings include nausea, vomiting, progressive sensorineural hearing loss, and nystagmus.

Ménière's disease.With Ménière's disease, labyrinthine dysfunction causes abrupt onset of vertigo, lasting minutes, hours, or days. Unpredictable episodes of severe vertigo and unsteady gait may cause the patient to fall. During an attack, a sudden motion of the head or eyes can precipitate nausea and vomiting.

Multiple sclerosis (MS).With MS, episodic vertigo may occur early and become persistent. Other early findings include diplopia, visual blurring, and paresthesia. MS may also produce nystagmus, constipation, muscle weakness, paralysis, spasticity, hyperreflexia, intention tremor, and ataxia.

Seizures.Temporal lobe seizures may produce vertigo, usually associated with other symptoms of partial complex seizures.

Vestibular neuritis.With vestibular neuritis, severe vertigo usually begins abruptly and lasts several days, without tinnitus or hearing loss. Other findings include nausea, vomiting, and nystagmus.

Other causes

Diagnostic tests.Caloric testing (irrigating the ears with warm or cold water) can induce vertigo.

Drugs and alcohol.High or toxic doses of certain drugs or alcohol may produce vertigo. These drugs include salicylates, aminoglycosides, antibiotics, quinine, and hormonal contraceptives.

Surgery and other procedures.Ear surgery may cause vertigo that lasts for several days. Administration of overly warm or cold eardrops or irrigating solutions can also cause vertigo.
