63
Q

Refers to any object or substance that has entered and become lodged in the ear canal. Common in children who may insert small objects like beads, buttons, or small toys into their ears. It can also accidentally enter the ear canal in adults, such as through accidents, falls, other activities, or even insects that may enter and get stuck in the ears. It may cause otalgia (ear pain), hearing loss, inflammation, discharge, tinnitus, and etc.,

A

External ear blockages–foreign bodies

64
Q

Occurs when an excessive amount of earwax (cerumen) builds up in the ear canal and becomes impacted or obstructed. Can cause a conductive hearing loss if there is a total occlusion and may also lead to otalgia, tinnitus, or vertigo. Can be caused by several factors, including the use of cotton swabs or other objects that push earwax deeper into the ear canal, naturally occurring ear canal shapes that make it more prone to impaction, or overproduction of earwax.

A

External ear blockages–Cerumen impaction (impacted cerumen)

65
Q

A

Otitis externa–bacterial or fungal infection

67
Q

Also known as necrotizing otitis externa. A severe and potentially life-threatening infection that primarily affects the external ear canal and the surrounding tissues. Characterized by the spread of infection beyond the ear canal into the adjacent structures, including the bones of the skull (osteomyelitis–bone inflammation). Typically occurs in older adults with weakened immune systems or underlying health conditions like diabetes. The infection can lead to severe complication, including cranial nerve palsies, meningitis, and bone destruction.

A

Otitis externa–malignant otitis externa

68
Q

What is dermatitis?

A

Could be included under otitis externa as it is sometimes called eczematous otitis externa. Condition characterized by inflammation and irritation of the skin lining the external ear canal. It may also be the result of eczema or psoriasis. Common symptoms of aural dermatitis include itching, redness, swelling, and flaking or scaling of the skin within the ear canal. In some cases, it may also lead to pain or discomfort.
Treatment typically involves identifying and addressing the underlying cause, which may include avoiding irritants or allergens, keeping the ear dry, and using topical corticosteroid creams or ear drops.

69
Q

___________________ is a medical term used to describe the formation of one or multiple boils or abscesses in the skin. A boil, also known as a furuncle, is a painful, pus-filled bump that forms when a hair follicle or oil gland becomes infected with bacteria.

A

Furunculosis

70

A

Perichondritis

71
Q

These are benign bony growths that can develop in the ear canal itself or on the surface of the bony portion of the ear canal. These growths are composed of mature bone tissue and are typically solitary, slow-growing, pedunculated, and non-cancerous.

A

Osteomas

72
Q

This is also a bony growth that develops on the surface of a bone but differs with osteomas from its histopathologic features. These are also typically benign and often covered by a layer of cartilage, exhibiting broad based elevations of bone involving the tympanic bone. They are usually multiple, bilaterally symmetrical. It can be triggered by prolonged exposure to cold water as a protective response to repeated exposure to cold water. Treatment is typically considered when these growths cause significant symptoms or complications, such as repeated ear infections or canal blockage. Surgical removal may be necessary in some cases to alleviate symptoms or improve hearing.

A

Exostosis

73
Q

These are abnormal growths of scar tissue that can form in response to an injury or trauma to the ear, including ear piercings, surgery, or other forms of ear trauma. This is a type of hypertrophic scar, but they differ from typical scars in that they tend to grow beyond the boundaries of the original wound and can become raised, thick, and firm.

A

Keloids

74
Q

These are fluid-filled or semi-solid sacs that can develop in or around the ear. They are typically non-cancerous and can vary in size from small to relatively large.

A

Ear cysts

75
Q

There are several types of cysts that can affect the ear but the most common one would be ________________________.

A

Sebaceous cysts

76
Q

These are openings or tears in the tympanic membrane which separates the external ear canal from the middle ear. Hearing loss may occur as the eardrum is unable to effectively transmit sound vibrations from the external ear to the middle ear and ossicular chain. Other symptoms could include ear pain, discharge (clear, bloody or pus-filled), tinnitus, or vertigo.

A

Eardrum perforations

77
Q

This is a condition characterized by the presence of white, chalky calcium deposits of scar tissue that can form on the tympanic membrane. These deposits can affect the normal functioning of the middle ear and hearing. Common characteristics may include: reduced hearing, calcium deposits, scar tissue, no pain or infection. Hearing aids may be recommended or surgical interventions, such as a tympanoplasty (eardrum repair surgery), may be considered

A

Tympanosclerosis

78
Q

This is a condition characterized by an imbalance in the pressure between the middle ear and the outside environment.

A

Negative middle ear pressure

79
Q

Common symptoms of negative middle ear pressure may include

A

Ear fullness or a plugged feeling, reduced hearing or muffled sounds, ear pain or discomfort and tinnitus.

80
Q

A condition characterized by the eustachian tube remaining open in the resting state (when it is normally closed). This is also a type of eustachian tube dysfunction. In some cases, it may lead to recurrent ear infections. Major symptoms include autophony (hearing one’s own voice, breathing, or heartbeat), echoing which may interfere with speech production, wave-like sounds, and a sensation of fullness in the ear. Pregnancy, weight loss, and some neurologic disorders (such as stroke) are thought to be amongst the most common predisposing factors.

A

Patulous eustachian tube

81
Q

What is otitis media?

A

Essentially mean an inflammation of the middle ear–it is a spectrum of diseases and one of the most common diseases in children. It can resolve spontaneously but may lead to permanent hearing impairment and life-long consequences.

82
Q

This is a condition in which there is fluid in the middle ear but no signs of acute infection. As fluid builds up in the middle ear and eustachian tube, it places pressure on the tympanic membrane.

A

Otitis media with effusion (OME)

83
Q

This is a progressive ear condition that affects the small bones (ossicles) in the middle ear, usually the stapes bone. It typically affects both ears, although one ear may be more affected than the other. Abnormal bone growth occurs around the ossicles, and the ossicular chain becomes remodeled. Commonly, the stapes bone becomes fixed or immobilized. Symptoms include unilateral gradual decline in hearing on one side followed by the other ear. Tinnitus and dizziness are also common,

A

Otosclerosis

84
Q

What is ossicular chain discontinuity?

A

This is the separation of the ME bones that results into a hearing loss. It can be caused by bone fractures (following a traumatic incident) and temporal bone or head trauma, eardrum perforation and trauma, complications from severe otitis media and cholesteatoma

85
Q

This is an inflammation of the membranous labyrinth of the inner ear and typically presents with vertigo, nausea, vomiting, tinnitus, and/or hearing loss. It is normally caused by a bacterial or viral infection; however, it can be a manifestation of systemic autoimmune disease or human immunodeficiency virus in some cases. Swelling of both branches of vestibulocochlear nerve

A

Labyrinthitis

86
Q

What is vestibular neuritis?

A

This refers to swelling of one branch of the vestibulocochlear nerve (the vestibular portion), which affects balance. The condition is also thought to be viral in origin, in contrast with labyrinthitis that could also be bacterial.
When this nerve becomes inflamed or swollen, the signal is interrupted causing the brain to read the information incorrectly. This results in dizziness, vertigo and other balance-related symptoms.

87
Q

This is a condition involving the otosclerosis located in the otic capsule, leading to sensorineural or mixed hearing loss. It typically arises from stapes fixation.

A

Cochlear otosclerosis
