Electrophysiological monitoring during acoustic neuroma and other posterior fossa surgery.
Techniques used to monitor the function of the seventh and eighth cranial nerves during acoustic neuroma and other posterior fossa surgery are reviewed. The auditory brainstem response (ABR), electrocochleogram (ECochG) and direct recording from the auditory nerve (CNAP) were compared. The best technique is the ECochG, although in many cases, the CNAP should be used as a back-up technique. The ...
متن کاملIntraoperative Somatosensory and Motor Evoked Potential Recording and Electroencephalographic Monitoring Usefulness During Aneurysm Surgery
In the last 20 years, there have been advances in techniques and instrumentation for intracranial aneurysm exposure and obliteration [94]. However, it seems that 32% of the patients, who underwent surgery, suffer a fatal outcome or some form of sequelae [20]. Primary brain damage due to subarachnoid haemorrhage (SAH) and to a vasospasm, is the major cause of mortality and morbidity; but surgery...
متن کاملVisual evoked potential monitoring of optic nerve function during surgery.
A study was made with intra-operative flash--visual evoked potentials (VEP) monitored using a fibre-optic/contact lens photo stimulator in 57 patients undergoing intra-orbital surgical procedures with potential risk to the optic nerve. The VEPs recorded under enflurane and nitrous oxide anaesthesia did not differ significantly in latency or amplitude from the pre-operative recordings. Transient...
متن کاملSleep Apnea Syndrome after Posterior Fossa Surgery: A Case of Acquired Ondine's Curse
Introduction: Ondine’s Curse is a catastrophic but rare condition in adults. It is referred to as a congenital or acquired condition, in which the patient cannot breathe automatically while asleep. Acquired causes of this disease can be any cause affecting the ventrolateral part of the medulla, which is considered to be the breathing center in humans. Case Report: A 51-year-old woman, with...
متن کاملComparison of transcranial electric motor and somatosensory evoked potential monitoring during cervical spine surgery.
BACKGROUND There has been little enthusiasm for somatosensory evoked potential monitoring in cervical spine surgery as a result, in part, of the increased risk of motor tract injury at this level, to which somatosensory monitoring may be insensitive. Transcranial electric motor evoked potential monitoring allows assessment of the motor tracts; therefore, we compared transcranial electric motor ...
