The other main type is otitis media with effusion (OME), typically not associated with symptoms, [1] although occasionally a feeling of fullness is described; [4] it is defined as the presence of non-infectious fluid in the middle ear which may persist for weeks or months often after an episode of acute otitis media. [4] Chronic suppurative ...
The most common aetiology of acute otitis externa is bacterial infection, [5] while chronic cases are often associated with underlying skin diseases such as eczema or psoriasis. [6] A third form, malignant otitis externa, or necrotising otitis externa, is a potentially life-threatening, invasive infection of the external auditory canal and ...
Otitis media. Acute otitis media is an infection of the middle ear. More than 80% of children experience at least one episode of otitis media by age 3 years. [23] Acute otitis media is also most common in these first 3 years of life, though older children may also experience it. [19]
S. pneumoniae (sometimes called pneumococcus), is a leading cause of bacterial pneumonia and the occasional etiology of otitis media, sinusitis, meningitis, and peritonitis. Inflammation is thought to be the major cause of how pneumococci cause disease, hence the tendency of diagnoses associated with them to involve inflammation.
[2] [3] Mastoiditis is usually caused by untreated acute otitis media (middle ear infection) and used to be a leading cause of child mortality. With the development of antibiotics , however, mastoiditis has become quite rare in developed countries where surgical treatment is now much less frequent and more conservative, unlike former times.
Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position.. The eardrum comprises two parts: the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa.
[1] [2] Otologic surgery generally refers to surgery of the middle ear and mastoid related to chronic otitis media, such as tympanoplasty (ear drum surgery), ossiculoplasty (surgery of the hearing bones) and mastoidectomy. Otology also includes surgical treatment of conductive hearing loss, such as stapedectomy surgery for otosclerosis.
Conductive hearing loss developing during childhood is usually due to otitis media with effusion and may present with speech and language delay or difficulty hearing. Later onset of conductive hearing loss may have an obvious cause such as an ear infection, trauma or upper respiratory tract infection or may have an insidious onset related to ...
