Video Telescope Operating Monitor (VITOM) 3D: preliminary experience in cranial surgery. Technical Case Report.
Optimal vision and ergonomics are important factors contributing to achievement of good results during neurosurgical interventions. The operating microscope and the endoscope have partially filled the gap between the need for good surgical vision and maintenance of a comfortable posture during surgery. Recently, a new technology called video-assisted telescope operating monitor or exoscope has been used in cranial surgery. The main drawback with previous prototypes was lack of stereopsis. We present the first case report of cranial surgery performed using the VITOM 3D, an exoscope conjugating 4K resolution view and three-dimensional technology, and discuss advantages and disadvantages compared with the operating microscope. ⋯ VITOM 3D is a video system that has overcome the lack of stereopsis, a major drawback of previous exoscope models. It has many advantages regarding ergonomics, versatility, and depth of field compared with the operating microscope, but the holder arm and the mechanism of repositioning, refocusing, and magnification need to be ameliorated. Surgeons should continue to use the technology they feel confident with, unless a distinct advantage with newer technologies can be demonstrated.

Intraoperative neuromonitoring (IONM) has been reported to be sensitive and specific in the detection of neurologic injury during spinal surgery. The purpose of this study was to clarify the incidence of C5 palsy using multimodality IONM and to compare the accuracy of multimodality IONM to predict postoperative C5 palsy with isolated transcranial motor evoked potentials (MEPs). ⋯ Incidence of any neurologic deficit, including C5 palsy, during laminoplasty while using multimodality IONM was relatively low. MEP alerts in the deltoids or biceps had 100% sensitivity and 98.4% specificity for predicting a postoperative deficit. Somatosensory evoked potentials did not appear to be helpful in predicting postoperative deficits.

To investigate the baseline patient characteristics, nonoperative modalities, surgical procedures, and complications rates of surgical cervical spondylotic myelopathy (CSM) patients. To evaluate risk factors for developing complications and compare the changes in health-related quality of life (HRQOL) from baseline to 2 years postoperatively. ⋯ The overall complication rate was 7.4% for the cohort. Baseline clinical information, comorbidities, use of nonoperative treatment modalities, and procedure type were not significantly associated with an increased risk of complications. Previous cervical spine surgery increased the risk of complications by 9-fold. The patients showed significantly improved SF-36 PCS, SF-36 MCS, and NDI scores at 2 years after surgery.
