Pus is an exudate, typically white-yellow, yellow, or yellow-brown, formed at the site of inflammation during bacterial or fungal infection. An accumulation of pus in an enclosed tissue space is known as an abscess, whereas a visible collection of pus within or beneath the epidermis is known as a pustule, pimple, or spot.

OTITIS MEDIA WITH EFFUSION • Also called serous otitis media, secretory otitis media, mucoid otitis media, glue ear. • An insidious condition characterized by accumulation of non-purulent effusion in the middle ear cleft. • Effusion often thick and viscid but thin and serous at times. The fluid is nearly sterile. • Most common in school ...
Otitis serosa Serous otitis media with effusion (OME) is a chronic inflammatory disease of the mucoperiosteal lining of the Eustachian tube, middle ear, and mastoid air cells. The hearing impairment related to this disorder is caused by recurrent accumulation of fluid behind the tympanic membrane.
OTITIS MEDIA WITH EFFUSION • Fluid in the middle ear once considered sterile but disputed by several studies. • Symptoms include CHL and aural fullness in the young child. • Can be asymptomatic with eventual language and speech development • 85-90% resolve at 3 months and this reduces to 20-30% there after • High prevalence has been associated with adenoid …
Chronic otitis media with effusion (OME) is differentiated from acute otitis media (AOM) because it is usually characterized by which of the following? a. fever as high as 40 degrees C (104 degrees F) b. severe pain in the ear c. nausea and vomiting d. a feeling of fullness in the ear. d. a feeling of fullness in the ear. 32.
Chronic suppurative otitis media is a persistent drainage (discharge) of the middle ear that lasts longer than 6-12 weeks, accompanied by a perforated eardrum. Chronic aspiration may occur with cholesteatoma or cholesteatoma, and both cases may have a very similar clinical history (cholestetaom or cholesteatoma, a tumor of the epithelial cells containing bone epithelial cells that can dissolve bone tissue by acting as a tumor. In chronic suppurative otitis media, it may be difficult to treat the hole in the tympanic membrane, in which the discharge of the chronic infection.
Causes of Chronic Suppurative Otitis Media (CSOM) Disease. CSOM occurs as a result of a chronic inflammatory process that develops after permanent hole formation in the eardrum due to traumatic causes, acute infection or surgical procedure (iatrogenic).
Chronic suppurative otitis media (CSOM) is a chronic otitis media and inflammation of the mastoid bone, which is accompanied by a persistent ear canal hole, in which the inflammatory discharge from the middle ear is discharged, manifested by the symptoms of hearing loss and ear discharge. Usually, chronic ear discharge lasts for more ...
Usually, chronic ear discharge lasts for more than 6-12 weeks. There are two different forms accompanied by cholesteatoma (inflammation foci arising from skin cells behind the eardrum, middle ear) and without cholesteatoma. The clinical history of both conditions can be very similar.
Pseudomonas aeruginosa, Staphylococcus aureus, Proteus species, Klebsiella pneumoniae and diphthroids are the most common bacteria found in examinations of chronic ear discharge. Anaerobic (breeding in the presence of oxygen) bacteria and fungi can develop simultaneously with aerobic bacteria (that grow in the presence of oxygen) in a symbiotic relationship. P aeruginosa is the most common organism detected in chronic ear discharge. In the last few years, various researchers have identified Pseudomonas in 48-98% of CSOM patients. These mixed microbial factors that can be seen in the disease reduce the effectiveness of medical treatment.
Antibiotic treatment can be changed according to the culture and antibiogram results. Chronic labyrinthitis is characterized by dizziness, tinnitus, and hearing loss. Most often, the infection reaches the inner ear through the lateral canal (outer semicircular canal).
Chronic mastoiditis is mostly associated with chronic suppurative otitis media and especially cholesteatoma formation . Cholesteatomas are benign populations of the squamous epithelium that can alter and alter the normal structure and function of the surrounding soft tissue and bone. This destructive process is accelerated in the presence of active infection by secretion of osteolytic enzymes by epithelial tissue. As seen in the above photo and at the end of the link, in the patient with chronic otitis media, the ear tomography (temporal bone CT) of the patient revealed a soft tissue mass filling the left mastoid bone cells, and the middle ear destroyed the ossicular chain.
Acute otitis media is usually a complication of eustachian tube dysfunction that occurs during a viral upper respiratory tract infection.
Antibiotic therapy can be deferred in children two years or older with mild symptoms. High-dose amoxicillin (80 to 90 mg per kg per day) is the antibiotic of choice for treating acute otitis media in patients who are not allergic to penicillin.
Otitis media is among the most common issues faced by physicians caring for children. Approximately 80% of children will have at least one episode of acute otitis media (AOM), and between 80% and 90% will have at least one episode of otitis media with effusion (OME) before school age. 1, 2 This review of diagnosis and treatment ...
Children two years or older without severe signs or symptoms: observation or antibiotic therapy for five to seven days. Persistent symptoms (48 to 72 hours) Repeat ear examination for signs of otitis media. If otitis media is present, initiate or change antibiotic therapy.
Otitis media with effusion is defined as middle ear effusion in the absence of acute symptoms. Antibiotics, decongestants, or nasal steroids do not hasten the clearance of middle ear fluid and are not recommended. Children with evidence of anatomic damage, hearing loss, or language delay should be referred to an otolaryngologist.
An AOM diagnosis requires moderate to severe bulging of the tympanic membrane, new onset of otorrhea not caused by otitis externa, or mild bulging of the tympanic membrane associated with recent onset of ear pain (less than 48 hours) or erythema. C.
Usually, AOM is a complication of eustachian tube dysfunction that occurred during an acute viral upper respiratory tract infection. Bacteria can be isolated from middle ear fluid cultures in 50% to 90% of cases of AOM and OME. Streptococcus pneumoniae, Haemophilus influenzae (nontypable), and Moraxella catarrhalis are the most common organisms. 3, 4 H. influenzae has become the most prevalent organism among children with severe or refractory AOM following the introduction of the pneumococcal conjugate vaccine. 5 – 7 Risk factors for AOM are listed in Table 1. 8, 9
Causes of otitis media. Otitis media is caused by a virus or by bacteria that lead to an accumulation of fluid behind the eardrum. This condition can result from a cold, allergy or respiratory infection.
If your child often suffers from otitis media (several times each year), then you must talk to your family doctor about it. An operation called myringotomy - a minor surgical incision - can be necessary. During the operation the eardrum is opened to remove the fluid.
The accumulation of fluid in the middle ear during otitis media causes earache, swelling and redness - which is called acute otitis media and also prevents the eardrum from vibrating properly, which typically results in (temporary) hearing problems.
Otitis media is the most common cause of hearing loss among children, and it occurs typically during winter or spring. Otitis media is an inflammation of the middle ear and can occur in either one or both ears at the same time. In general, otitis media is not serious and does not normally cause permanent hearing problems if treated properly.
