In this paper, we introduce a new approach for modeling closed surfaces. After working with several methods, we think that none really takes into account both the local and global characteristics of an object within a single coherent model. For instance, parametric surfaces endure changes of topology with difficulty and can mainly be used for local modifications of an object’s surface. On the o...

Subacute otitis media is a well-known pathology of ENT practice which is easily diagnosed and subsequently treated in the outpatient clinic. The rate of complications in acute otitis media is lower than in chronic otitis media. We present here the history of a young patient with subacute otitis media who developed both localized labyrinthitis and facial palsy requiring surgical treatment. We co...

Otitis media (OM) is an infection localized in the middle ear: mastoid, middle ear cavity, Eustachian tube. The classification of OM includes otitis media with effusion, otitis media without effusion, and chronic otitis media. A rare complication of chronic otitis is cholesterol granuloma of the petrous apex. It may develop in any aerated portion of the temporal bone but most commonly develops ...

BACKGROUND Chronic otitis media is a chronic inflammatory disease of the middle ear cleft which is manifested as deafness and ear discharge. It is a common condition affecting 0.5 - 30% of any community worldwide, and most common in developing countries. The prevalence mainly depends on age, low socio-economic status, overcrowding and limited medical facilities. OBJECTIVE To compare the clini...

A nation-wide survey was conducted to estimate the prevalence of otitis media and allied diseases through physical examination by otolaryngologic doctors from July to October, 1991. A sample study population was selected from a panel to be representative of the Korean population by multistage clustered and stratified random sampling method based on the National Census Data, 1990. Total number o...

OBJECTIVE To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. METHODS Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was b...

Otitis media is one of the most common infectious diseases of infancy; a reduction in its incidence would have a significant economic and social impact. Vaccines may play a role in the prevention of otitis media. This report discusses vaccines against pneumococci and influenza viruses. We reviewed the literature for results of studies examining the role of these vaccines in the prevention of ot...

Acute otitis media and otitis media with effusion are common childhood disorders, a source of significant morbidity, and a leading cause of antibiotic prescription in primary health care. Although effective treatments are available, some shortcomings remain, and thus better treatments would be welcome. Recent discoveries within the field of otitis media research relating to its etiology and pat...

Acute otitis media (AOM) is a common complication of upper respiratory tract infection whose pathogenesis involves both viruses and bacteria. We examined risks of acute otitis media associated with specific combinations of respiratory viruses and acute otitis media bacterial pathogens. Data were from a prospective study of children ages 6 to 36 months and included viral and bacterial culture an...

While both acute and chronic otitis externa represent conditions that are encountered commonly by primary care physicians, malignant otitis externa can be a diagnostic and therapeutic challenge to generalists and subspecialists alike. Malignant otitis eXterna is a devastating infection of the external auditory canal, which begins as a pseudomonas dermatitis but can progress to an invasive vascu...
