Usefulness of external anal sphincter EMG recording for intraoperative neuromonitoring of the sacral roots—a prospective study in dorsal rhizotomy

EMG recording of the EAS can be recommended for current intraoperative neuromonitoring and provides—indirectly by extrapolation—information on the sacral motor pathways of the external urethral sphincter (EUS), as the later has the same somatic innervation via the pudendal nerve and related S2, S3, and S4 roots.

Utility of direct stimulation of roots in spinal surgery.

Prevention of postoperative neurological deficits is a major concern of spinal surgeons and has led to the introduction and current development of intraoperative neurophysiological monitoring. We

Intraoperative Neurophysiology in Neurosurgery

As a rule in any scientific discipline, especially in clinical neuroscience, a reliable and simple methodology is the ultimate goal. The same rule can be implemented in the field of intraoperative

Evaluation of Xgene (R) , a Eurycoma longifolia Extract Enriched Penis CareCream, as a Novel Vehicle in Creating Penis Consciousness and Confidence in Keeping and Maintaining Erection for Penetrative Sex

A cream containing a Malaysian herb, Eurycoma longifolia, known to increase cellular cGMP and cAMP, was put to a study to evaluate its efficacy strengthening and maintaining penis tumescence.



Intraoperative motor and sensory monitoring of the cauda equina.

A set of standard techniques to monitor the motor and sensory function of the cauda equina is proposed for surgery in the lumbosacral spinal canal for the release of a tethered cord or the removal of

Use of anal sphincter electromyography during operations on the conus medullaris and sacral nerve roots.

This technique was employed intraoperatively in monitoring operations on the conus medullaris and sacral nerve roots in 10 patients with spinal dysraphism and permitted spinal operations in these 10 patients without changes in neurological or urological function.

The motor nerve supply of the external urethral sphincter muscles: An electrophysiologic study

The results of this study indicate that the pudendal nerve plays an important role in the innervation of the intrinsic external urethral muscle, i.e., somatic, and does not exclude the possibility that the autonomic nervous system also innervates this muscle.

Intraoperative recording of the bulbocavernosus reflex.

It is demonstrated that it is feasible, under certain anesthetic regimes, to intraoperatively monitor the BCR in both children and adults who did not have significantly affected function in sacral nervous structures.

This review documents a 94% baseline BCR acquisition rate among 100 consecutive cases in one institution and illustrates the power of the BCR to predict patient outcome or, much more importantly, reverse incipient patient injury in real time.

Intraoperative neurophysiology in tethered cord surgery: techniques and results

Mapping techniques allow identifying and sparing functional neural tissue and vice versa to cut nonfunctional structures that may contribute to cord tethering, though these may require a higher degree of neuromonitoring expertise.

Pudendal afferents mapping in posterior sacral rhizotomies.

Pudendal afferent mapping identified the sacral rootlets involved with genital and anal sensation and the preservation of such rootlets in sacral rhizotomies is considered to be important for minimizing postoperative bladder and bowel dysfunction.

Intraoperative monitoring of the dorsal sacral roots: minimizing the risk of iatrogenic micturition disorders.

It is proposed that the neurophysiological identification of roots and rootlets carrying afferent activity from the penile or clitoral nerves allows for rhizotomy of the S2 roots with the least possible risk of postoperative micturition and sexual dysfunction.
