The authors used high-resolution computed tomography (HRCT) for studying 52 congenitally malformed ears in 45 children between five and 10 years of age. In six children the malformations were bilateral. The malformations clinically manifested as microtia, atresia of the external auditory canal and conductive deafness. Analyzing anatomical details and pathological changes on HRCT axial sec...

Introduction  The tone-evoked auditory brainstem responses (tone-ABR) enable the differential diagnosis in the evaluation of children until 12 months of age, including those with external and/or middle ear malformations. The use of auditory stimuli with frequency specificity by air and bone conduction allows characterization of hearing profile. Objective  The objective of our study was to compa...

PURPOSE A recent study suggests that transcranial brain targeted light treatment via ear canals may have physiological effects on brain function studied by functional magnetic resonance imaging (fMRI) techniques in humans. We tested the hypothesis that bright light treatment could improve psychomotor speed in professional ice hockey players. METHODS Psychomotor speed tests with audio and visu...

BACKGROUND Ceruminous glands are modified apocrine glands, situated in the external auditory canal, that, together with sebaceous glands, produce cerumen, better known as ear wax. The neoplastic transformation of these structures is very rare and there have been few cases reported in the literature. CASE REPORT Syringocystadenoma papilliferum is one of the rarest tumors among benign tumors aris...

An incidental post-mortem finding is reported. Its clinical relevance is discussed. It is suggested that some EAC exostoses may have a similar origin and thus an association with IAC exostoses.

We present a case of bilateral otitis externa that did not respond to local treatment. Cutaneous biopsies revealed bilateral amyloid depositions secondary to multiple myeloma. Persistent, identical bilateral canal lesions may be the only manifestation of treatable systemic disease and should be biopsied, even though their bilaterality argues against malignancy.

An 83-year-old woman presented with a 10-year history of a slowly growing, painful mass in the left auricle and bloody otorrhea. We observed a sharply delineated, domelike blackish-brown verrucous nodular elevation with a greasy scaled surface extending from the left cavum concha into the external auditory meatus (Fig. 1). Gentle manipulation of the growth resulted in mild bleeding and caused s...
