Cranial nerve enhancement in the Guillain-Barre syndrome.
(73/84)
We report a case of Guillain-Barre syndrome with enhancement of multiple cranial nerves seen with postcontrast MR imaging. Clinical symptoms and electrodiagnostic studies reflected abnormalities of some but not all of the enhancing cranial nerves. (+info)
The use of Gore-tex vascular grafts in microvascular decompression for patients with hemifacial spasm--technical note.
(74/84)
Microvascular decompression was performed in 10 hemifacial spasm patients using Gore-tex vascular grafts as a prosthesis. Postoperative complication (transient deafness) occurred only in one patient, and recurrence in none during follow-up of 1-51 months, indicating that Gore-tex is a very effective prosthesis. (+info)
Facial schwannoma spreading into the middle cranial fossa and the cerebellopontine angle--case report.
(75/84)
A 53-year-old male presented with hearing impairment and facial nerve paralysis following tinnitus of the right ear. Neuroimaging revealed a tumor extensively damaging the temporal bone, and extending into the middle cranial fossa and cerebellopontine angle. The tumor was removed in a two-stage operation. The histological diagnosis was facial schwannoma. (+info)
Submandibular gland surgery: an audit of clinical findings, pathology and postoperative morbidity.
(76/84)
A series of 86 patients who underwent submandibular gland surgery were reviewed retrospectively. Of the 92 glands excised, non-neoplastic disease accounted for 96% of cases. Preoperative clinical findings were inconsistent such that early surgery should be considered for an enlarged non-tender submandibular gland. The incidence of temporary paresis of the lower branches of the facial nerve was 36% with full recovery, on average, 4 months after surgery. The low 'non-identification' approach to the submandibular gland appears to be the technique which offers the least likelihood of permanent damage to the lower branches of the facial nerve. (+info)
Primary paraganglioma of the facial nerve canal.
(77/84)
We report two cases of primary paraganglioma of the facial nerve canal. This entity should be considered in patients presenting with facial paresis or pulsatile tinnitus. Paraganglioma should be considered when a lesion appears to arise from the facial nerve canal. (+info)
Turbo spin-echo magnetic resonance imaging depiction of facial nerve compression by a vertebral artery in a patient with hemifacial spasm--technical note.
(78/84)
Turbo spin-echo magnetic resonance (MR) imaging of a patient with hemifacial spasm clearly demonstrated vascular compression of the facial nerve by the vertebral artery. The high resolution images of this method may be an appropriate alternative to preoperative cerebral angiography. Turbo spin-echo MR imaging is a diagnostic procedure of choice for patients with hemifacial spasm and possibly trigeminal neuralgia. (+info)
Greater superficial petrosal nerve: anatomy and MR findings in perineural tumor spread.
(79/84)
We report a case of perineural spread of adenoid cystic carcinoma along the greater superficial petrosal nerve. The anatomy of this nerve also is reviewed. (+info)
Hemifacial spasm due to compression of the facial nerve by vertebral artery-posterior inferior cerebellar artery aneurysm and elongated vertebral artery--case report.
(80/84)
A 62-year-old female presented with rapid aggravation of long-standing facial spasm occurring within a few months. Neuroimaging and angiography demonstrated compression of the root exit zone (REZ) of the facial nerve by an ipsilateral saccular aneurysm at the left vertebral artery (VA)-posterior inferior cerebellar artery bifurcation, in addition to the elongated VA. Neck clipping of the aneurysm and decompression of the REZ from the elongated VA and clipped aneurysm resulted in complete disappearance of the facial spasm. The aneurysm had very thin walls and was apparently about to rupture. Aggravation of long-standing hemifacial spasm may be a warning sign for rapid growth and rupture of a causative aneurysm. (+info)
