(Continued from page 28.) 8 and 9. Brain abscess.?The importance of middle-ear disease as a cause of brain abscess is very great; for it is estimated that from 40% to 50% (Gowers, 42 % ; Barker, 50%) of all brain abscesses which occur without external wound are due to suppurative otitis media. As to the position which an abscess in the brain from ear disease may occupy, statistics have been com...

Acquired medial canal fibrosis is a discrete clinicopathologicalentity characterized by formation ol fibrous tissue in the bony external auditory meatus. Over a seven-year period, a total of 14 operative procedures were performed on 12 ears involving 10 patients. Four cases had followed otitis externa, two were complications of suppurative otitis media, and three cases were iatrogenic. The caus...

The purpose of this study was to review our experience with a single case of mastoiditis associated with sigmoid sinus thrombosis and increased intracranial pressure, and to review the experience of others through prior publications. We reviewed a case of a 6-year-old boy with an acute otitis media and mastoiditis, with associated ipsilateral sigmoid sinus and contralateral distal transverse si...

IMPORTANCE In the limited number of Crohn disease cases involving the head and neck, there is a predilection for mucosal surfaces and rare reports of involvement in the postauricular region. To our knowledge, in all previously reported cases involving the head and neck, the patients had a known diagnosis of Crohn disease. OBSERVATIONS This case describes a 10-year-old boy with a history of ps...

The indigenous microbial flora of the middle ear cavity of Mongolian gerbils, Meriones unguiculatus, was isolated, characterized, and identified, showing it to be sparse and transitory. Organisms, when found in the middle ear cavity, were most likely to be Staphylococcus epidermidis-like organisms. Cerumen from the external auditory canal of these animals yielded mostly staphylococci, corynefor...

The antifungal activity and the chemical composition of essential oils (EOs) from some Mediterranean autochthonous plants were investigated against Malassezia pachydermatis, a fastidious opportunistic yeast usually involved in canine external otitis. Minimum inhibitory concentrations (MICs) of Anthemis nobilis, Citrus limon, Citrus paradisi, Illicium verum, Lavandula hybrida, Mentha piperita, O...

Abstract Background External auditory canal (EAC) masses can arise secondary to a multitude of ear pathologies like congenital, inflammatory, infective, or malignancy. The most common causes external are due otitis media—squamous and mucosal types, tubercular media, malignant externa, benign tumors osteomas, exostosis, pleomorphic adenoma, from the ceruminous sebaceous glands; squamous cell car...

Most necrotizing (malignant) external otitis (NEO) occurs in diabetic patients and is commonly caused by Pseudomonas aeruginosa. We report an acquired immunodeficiency syndrome (AIDS) patient with NEO caused by Aspergillus fumigatus in which computed tomography (CT) showed destructive petrous bone involvement and magnetic resonance imaging (MRI) of the ear discovered extensive soft tissue and f...

Chronic suppurative otitis media (CSOM) is a clinical condition where a patient suffers from external and middle ear infection caused mostly by bacteria or by fungi resulting in ear discharge. Identification of the causative microorganism and initiation of appropriate antimicrobial chemotherapy is needed in patients suffering from CSOM. Infections of the ear if happen to be chronic in nature ha...
