What are the types of chronic suppurative otitis media?
Two types of CSOM are recognized, a mucosal disease (safe type) and an epithelial disease (unsafe type) . Worldwide the CSOM is one of the most common infectious diseases in childhood and is a common cause of impaired hearing, in particular, in resource-limited parts of the world [4,5].
What is the treatment for chronic suppurative otitis media?
Treatment. When chronic suppurative otitis media flares up, doctors prescribe antibiotic ear drops. People with severe flare-ups are also given antibiotics by mouth. Except for prescribed ear drops, the ear must be kept dry when a perforation is present.
What causes chronic suppurative otitis media?
Etiology and Risk Factors Frequent upper respiratory tract infections and poor socioeconomic conditions (e.g., overcrowded housing, poor hygiene and nutrition) are often associated with the development of chronic suppurative otitis media.
What is the difference between chronic otitis media and chronic suppurative otitis media?
CSOM is differentiated from chronic otitis media with effusion, in which there is an intact tympanic membrane with fluid in the middle ear but no active infection. CSOM does not include chronic perforations of the eardrum that are dry, or only occasionally discharge, and have no signs of active infection.
Which is the most common complication of chronic suppurative otitis media?
The most common intracranial complication was lateral sinus thrombophlebitis (19.5%), followed by perisigmoid sinus abscess (13.5%), meningitis (9%), brain abscess (6.5%), and extradural abscess (4.5%).
What is the difference between suppurative and Nonsuppurative otitis media?
Suppurative otitis media is a fluid buildup in the ear with pus formation, while nonsuppurative lacks pus formation.
What are the symptoms of chronic suppurative otitis media?
Chronic suppurative otitis media is characterised by recurrent or persistent ear discharge (otorrhoea) over 2-6 weeks through a perforation of the tympanic membrane. Typical findings may also include thickened granular middle ear mucosa, mucosal polyps, and cholesteatoma within the middle ear.
What is acute suppurative otitis media?
DEFINITION Acute otitis media (AOM) is an acute, suppurative infectious process marked by the presence of infected middle ear fluid and inflammation of the mucosa lining the middle ear space (picture 1).
What are the extracranial complications of otitis media?
The complications of otitis media were classified as extracranial and intracranial. Extracranial complications were mastoiditis, mastoid abscess, mastoid fistula, Bezold’s abscess, Luc’s abscess, zygomatic abscess, facial nerve paralysis, labyrinthitis and labyrinthine fistula.
What are suppurative infections?
Suppurative infections are typically caused by pyogenic bacteria, and are characterised by the formation of purulent exudates (pus). These infections may occur anywhere in the body and are particularly life-threatening when pertaining to the central nervous system (CNS).
What is chronic non suppurative otitis media?
Disease Ontology : 12 A otitis media which involves transudation of fluid in the middle ear without pus formation. MalaCards based summary : Non-Suppurative Otitis Media, also known as nonsuppurative otitis media, is related to eustachian tube disease and acute serous otitis media.
