New computed tomography (CT) and magnetic resonance (MR) techniques allow more detailed anatomic studies of the inner ear. CT is still the best technique to study patients with fractures, congenital malformations and otodystrophies involving the inner ear. During recent years MR imaging has emerged as an excellent method to detect pathology in the internal… (More)
The purpose of this prospective study was to assess the impact of Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) in the surgical management of carcinomas with mandibular bone invasion. Thirty-five patients with squamous cell carcinoma of oral cavity or oropharynx, with mandibular spread, were studied with both imaging methods before surgical… (More)
Choanal stenosis is usually a congenital anomaly in children. Acquired choanal stenosis after radiotherapy for nasopharyngeal carcinoma is a very rare pathology; only two publications report seven cases in the literature. We describe the clinical history, preoperative evaluation, surgical treatment and outcome of a case of acquired choanal stenosis after… (More)
The techniques of free tissue transfers are mainly used for mandibular reconstruction by specialized surgical teams. This type of reconstruction is mostly realized in matters of head and neck cancers affecting mandibular bone and requiring a wide surgical resection and interruption of the mandible. To decrease the duration of the operation, surgical… (More)
We encountered a case of acquired perilymphatic fistula in which the origin of the disease, namely, the stapes begin medially displaced into the vestibule, was shown by thin-section CT. Accordingly, we recommend that every patient with suspected perilymphatic fistula of traumatic origin undergo high-resolution CT of the petrous bone.
Acoustic neurinomas must be diagnosed as early as possible for the tumour to be removed while it is still small and the facial and, sometimes, auditory functions to be preserved. Since 89% of neurinomas lie on the vestibular nerve, enhancing the sensitivity of test exploring this nerve is important. Bilateral bithermal caloric stimulation is more sensitive… (More)
The authors have used CT scans and MRI to study pathology in anatomical and radiological correlations of brain slices. The CT scan was particularly useful for studying structures at the skull base, although at the level of the posterior fossa such scans could visualize only those tumors that were larger than 8 mm. even after injection. The CT scan was found… (More)
