the objective of the current study was to determine the anatomical features of the auditory ossicles inhamster. twenty temporal bones from 10 adult hamsters, weighing 275-300 g were used. after dissectingthem, the features of the ossicles were assessed with an ocular micrometer and photographed by astereomicroscope. finally, all data were evaluated and analysed using the sigma statt software. t...

Inflammation in the middle ear mucosa, which can be provoked by different primary factors such as bacterial and viral infection, local allergic reactions and reflux, is the crucial event in the pathogenesis of otitis media with effusion (OME). Unresolved acute inflammatory responses or defective immunoregulation of middle inflammation can promote chronic inflammatory processes and stimulate the...

OME, middle ear disease with many denominations, is a subacute or chronic inflammation by multifactorial etiology, characterized by the presence of serous, mucous, or mixed, non-infected secretion, persistent for more than three months in the middle ear. The incidence is higher in children (ratio children / adults = 10/1), particularly pre-school (61%) than school age (22%), occurs mainly in wi...

CONCERTED EFFORTS are being made to reduce the incidence of middle ear disease among American Indians, who experience rates several times those of the general U.S. population (1,2). Hearing loss attributable to ear infections in early life also is considerably higher among Indians. To assure that control programs achieve maximum effectiveness and employ resources to optimum advantage, priority ...

Patient population: Pediatric patients (>2 months old) and adults Objectives: (1) Limit acute symptoms and suppurative complications caused by acute otitis media. (2) Maximize language development and minimize long term damage to middle ear structure associated with otitis media with effusion. (3) Limit complications of antibiotic therapy including the development of antibioticresistant bacteria.

Abstract Introduction Actinomycosis, a rare infection of the middle ear, has less than 50 documented cases worldwide. Actinomyces are an anaerobic, filamentous bacterium causing granuloma formation and suppurative infection. Case We present young male with nine-month history unilateral, yellow coloured otorrhoea hearing loss. Swabs showed no growth, not responding to oral or topical antibiotics...

Otitis media (OM), a middle-ear infection, is the most common childhood illness treated by pediatricians. If inadequately treated, OM can result in long-term chronic problems persisting into adulthood. Children with chronic OM or recurrent OM often have conductive hearing loss and communication difficulties and require surgical treatment. Tympanostomy tube insertion, the placement of a small dr...

Mucormycosis is the common name given to clinical disease caused by fungi of the order Mucoraceae of class zygomycetes. Mucormycosis is a life threatening fungal infection which commonly affects the Immunocompromised hosts almost uniformly in developing as well as industrialised countries. Mucorales are distributed into six families all of which can cause cutaneous and deep fungal infections. O...

Cholesterol granuloma is a pathological lesion affecting the mastoid air cells due to partial obstruction of its aireation. It is commonly unilateral. It is usually associated with glue ear with intact ossicles. Histologically, it is characterized by the presence of large pointed crystals and giant cells. Its treatment is either conservative steroid therapy or surgical removal of the granuloma ...

Development of intracranial complications from middle ear infections might be difficult to diagnose. We compared radiological and surgical findings of 26 patients affected by otogenic meningitis. Results of our analysis showed that surgery is more reliable than imaging in revealing bone defects. Therefore, suggest that surgery be performed for diagnosis and eventual management of all cases of s...
