These factors make reporting operative outcome difficult to classify and compare. Rates of postoperative facial nerve dysfunction depend not only on surgical expertise but also on tumor size, location, and differentiation. Drs Savvas and Alberty had full access to all the data in the study and take responsibility for the integrity of the data and the accuracy of the data analysis. Monitoring requires an initial expense because a console must be purchased; however, this cost is offset quickly because the console will be used frequently during otological and thyroid surgery. Although it does not improve the facial prognosis in first-line surgery, it does improve the facial prognosis in reoperations. In our PP and TP groups, we found no statistical differences between the subgroups with and without monitoring. Purchase access Subscribe to JN Learning for one year.
Peripheral Nerve Stimulator - Train of Four Monitoring
In a case series study, Beatty et al discussed their experiences with the use of continuous intra-operative EMG recording during spinal surgery. There was at least a non-significant trend towards more frequent perforation of the pedicle in the monitor group. This technique may also be used during otologic procedures in which facial nerve manipulation is anticipated in the management of recurrent cholesteatoma, temporal bone trauma, congenital deformity, or purposeful access for cochlear implantation. Can triggered electromyograph thresholds predict safe thoracic pedicle screw placement. Compared to other neurophysiological methods, EMG is a viable alternative.
Confirmation of surgical activity with the level of the EMG was correlated. Color-coded placement guides are included in the NIM software. Decompression and monitor of facial nerve during cholesteatoma surgery in petrous part of temporal bone. Monitoring During Spinal Surgery:
Alfred Armand Louis Marie Velpeau successfully identified the facial nerve trunk in The entire lateral part of the parotid gland was resected with the tumor. Exclusion criteria consisted of a preoperative facial nerve weakness or paralysis, revision operations, combined operations extending to the neck such as a neck dissection , and cases with facial nerve reconstruction. A main focus of this chapter is a review of several prospective clinical trials that have been performed in recent years that have analyzed the benefit of electrophysiological nerve monitoring during parotid surgery.
