Microvascular Decompression for Glossopharyngeal Neuralgia in the Semi-Sitting Position: A Report of Two Cases.

The semi-sitting position is well known to neurosurgeons. However, there are few reports of microvascular decompression surgery for glossopharyngeal neuralgia performed using the semi-sitting position. The semi-sitting position is not widely adopted in Japan, but it is considered to be a very useful neurosurgical position.

Limitations of median nerve somatosensory evoked potential monitoring during carotid endarterectomy.

Objective: Hypoperfusion during carotid artery cross-clamping (CC) for carotid endarterectomy (CEA) may result in the major complication of perioperative stroke. Median nerve somatosensory evoked potential (MNSSEP) monitoring, which is an established method for the prediction of cerebral ischemia, has low sensitivity in detecting such hypoperfusion. In this study the authors sought to explore the limitations of MNSSEP monitoring compared to tibial nerve somatosensory evoked potential (TNSSEP) monitoring for the detection of CC-related hypoperfusion.

Delayed Postoperative Spinal Epidural Hematoma after Cervical Laminoplasty.

A 56-year-old man underwent cervical laminoplasty for cervical spondylosis. On the 7th postoperative day, he suddenly felt severe neck pain, and tetraplegia developed rapidly over 1.5 hrs.

Clinical Characteristics and Management of C3-4 Degenerative Cervical Myelopathy.

Single-level anterior cervical discectomy and fusion (ACDF) was performed at C3-4; non-C3-4 ACDF patients of the authors' random sample of ACDF patients were compared with C3-4 ACDF patients. The radiological study of C3-4 ACDF patients shows that they had significant cervical lordosis, and cervical motion was dependent on the C3-4 segment, which accounted for 39.8% of C2-7 range of intervertebral motion (total motion).

Radiological study of C3-C4 level surgical cases of cervical spondylosis.

Objective: The purpose of this study was to elucidate the pathological characteristics of C3-C4 cervical spondylotic myelopathy (CSM) from the radiological study.

Materials And Methods: A total of 31 patients with single level anterior cervical discectomy and fusion (ACDF) at C3-C4 and 46 patients with single level ACDF at C5-C6 were included in this study. We selected C5-C6 level as a representative of the lower cervical level.
