BACKGROUND Schwannomas are uncommon benign tumors of the external auditory canal. The clinical features, the differential diagnosis, and the surgical treatment of these lesions are discussed. CASE PRESENTATION A 51-year-old patient presented with a mass obliterating the external auditory meatus. Excisional biopsy was performed. Diagnosis was reported to be schwannoma by histopathologic examin...

Congenital external auditory canal atresia is a disorder with a prevalence of one in 10 000-20 000 live births and is bilateral in one third of the patients. With a conductive hearing loss of 60 dB, even unilateral atresia restricts hearing related social skills. The degree of middle ear deformity may make reconstruction surgery impossible or too hazardous, thus bone-conduction hearing aids hav...

OBJECTIVE To present a case in which diffuse cystic bronchiectasis was associated with left microtia/external auditory canal atresia. CLINICAL PRESENTATION A 10-year-old girl suffering from cough, fever, dyspnea and sputum for 6 months was transferred to our clinic due to the diagnosis of bronchopneumonia. She had recurrent episodes of bronchopneumonia. On examination, left microtia and left ...

Melanoma of the ear canal is extremely rare; due to its hidden area, most would present late in their history. We present the first case reported, of a black pigment foreign body mimicking a melanoma in the external auditory canal. A 14 year old Chinese male presented with right sided otalgia and itch. Otoscopic examination revealed an irregular black naevus in the right auditory canal. An intr...

OBJECTIVES Measuring core body temperature is crucial for preventing heat stress disorders in workers. We developed a method for measuring auditory canal temperatures based on a thermocouple inserted into a sponge-type earplug. We verified that the tip of this thermocouple is positioned safely, allowing the wearer to engage in normal physical tasks; this position averaged 6.6 mm from the tympan...

We present the first case report of a labyrinthine artery aneurysm masquerading as an internal auditory canal tumor. A 72-year-old woman presented with sudden onset right facial paralysis, facial pain, hearing loss, and vertigo. She demonstrated dense right-sided facial paralysis involving all branches of the facial nerve, left beating horizontal nystagmus, and anacusis of the right ear. Magnet...

PURPOSE First aim of the study was to define normal shape and diameter of the internal auditory canal (IAC). In the second part the clinical relevance of IAC-enlargement was analyzed, considering also lesions of the subtle structures at the fundus of the internal auditory canal. MATERIALS AND METHODS 440 high resolution CT-scans of the temporal bone were used for retrospective analysis of the...

BACKGROUND The fissures of Santorini have long been known as a gateway for disease to pass from the external auditory canal to the periparotid and neck spaces. Although anatomically understandable, description of disease that originates in the parotid gland and extends through the fissures to the external auditory canal is rare. This is, in fact,the first presentation of such a patient at our i...
