Otitis externa. A moderate case of otitis externa. There is narrowing of the ear channel, with a small amount of exudate and swelling of the outer ear. Otitis externa, also called swimmer's ear, [ 1] is inflammation of the ear canal. [ 2] It often presents with ear pain, swelling of the ear canal, and occasionally decreased hearing. [ 2]
Otitis media is a group of inflammatory diseases of the middle ear. [ 2] One of the two main types is acute otitis media ( AOM ), [ 3] an infection of rapid onset that usually presents with ear pain. [ 1] In young children this may result in pulling at the ear, increased crying, and poor sleep. [ 1]
Eustachian tube dysfunction can be caused by a number of factors. Some common causes include the flu, allergies, a cold, and sinus infections. [ 6] In patients with chronic ear disease such as cholesteatoma and chronic discharge, studies showed that they have obstructive pathology at the ear side of the Eustachian tube. [ 7][ 5] Given that ...
Conductive hearing loss (CHL) occurs when there is a problem transferring sound waves anywhere along the pathway through the outer ear, tympanic membrane (eardrum), or middle ear . If a conductive hearing loss occurs in conjunction with a sensorineural hearing loss, it is referred to as a mixed hearing loss. Depending upon the severity and ...
Sensorineural hearing loss ( SNHL) is a type of hearing loss in which the root cause lies in the inner ear, sensory organ ( cochlea and associated structures), or the vestibulocochlear nerve ( cranial nerve VIII). SNHL accounts for about 90% of reported hearing loss. [citation needed] SNHL is usually permanent and can be mild, moderate, severe ...
Tympanoplasty is the surgical technique of removal of the retracted area from the middle ear and reconstruction of the tympanic membrane. Some surgeons use cartilage (taken from the outer ear) to stiffen the eardrum with the aim of preventing further retraction. [ 9] Surgical removal is required once a cholesteatoma has formed.
Otitis media, or middle ear infection, involves the middle ear. In otitis media, the ear is infected or clogged with fluid behind the ear drum, in the normally air-filled middle-ear space. This is the most common infection and very common in babies younger than 6 months. This condition sometimes requires a surgical procedure called myringotomy ...
Specialty. Otorhinolaryngology. Otosclerosis is a condition of the middle ear where portions of the dense enchondral layer of the bony labyrinth remodel into one or more lesions of irregularly-laid spongy bone. As the lesions reach the stapes the bone is resorbed, then hardened ( sclerotized ), which limits its movement and results in hearing ...
