Ear carcinoma constitutes 0.5% of all cancers of the head and neck hardly, however with poor prognosis. In the study we use University of Pittsburgh Staging System. This study is retrospective analysis of the surgical treatment outcomes of the patients with external and middle ear carcinomas in the ENT Department at the Medical University of Warsaw in years from 2004 to 2008. Histopatologicalll...

Intracochlear schwannoma may cause progressive or sudden sensorineural hearing loss. Radiologic findings can be overlooked especially when attention is focused on the internal auditory canal. Otolaryngologists should be familiar with the diagnosis and treatment of this important but uncommon lesion.

Cochlear nerve (CN) aplasia refers to the absence of a visible CN on oblique sagittal magnetic resonance images of the lateral aspect of the inner auditory canal (IAC). Magnetic resonance (MR) is the preferred technique in patients with sensorineural hearing loss and/or vertigo; however, computed tomography (CT) is used to evaluate the IAC or facial nerve canal. Three types of aplasia or hypopl...

In most series, 90% of cerebellopontine angle tumors are vestibular schwannomas. Meningiomas and epidermoid tumors follow with decreased frequency. Ganglioneuroma is a benign tumor usually found in the retroperitoneum and posterior mediastinum. We report a case of a 21-year-old man with gradual sensorineural hearing loss and a minimally enhancing lesion of the internal auditory canal, which was...

The external auditory canal contains ceruminous glands, which are modified apocrine sweat glands, along with sebaceous glands. Tumors that originate from ceruminous glands are very rare; thus, the classification, clinical behavior, and management of these tumors remain debatable. Here we present a case of ceruminous adenocarcinoma arising from the external auditory canal. Although most authors ...

Ependymomas are relatively rare glial neoplasms that arise from ependymal cells. The majority of cases (>75%) arise from the fourth ventricle in the posterior fossa. These tumours may expand locally, extend along subarachnoid spaces, and disseminate through the cerebrospinal fluid. Sometimes, they may extend into the cerebellopontine angle and mimic the clinicoradiological appearance of an extr...

OBJECTIVES To determine the relationship in detail between the tympanic and the labyrinthine segments of the facial nerve and the relationship between the bony structures and the neighboring nerve. MATERIALS AND METHODS Measurement of the length of the segment of the facial nerve within the internal auditory canal and the lengths of the labyrinthine and tympanic segments were made on fourteen...

Hearing conservation in acoustic neuroma surgery via the retrosigmoid approach depends upon a good exposure of the internal auditory canal from behind avoiding labyrinthine injury. The accessibility is influenced largely by the individual characteristics of the temporal bone and the variability of the surgical landmarks is the result of different skull base shapes among different races. The aim...
