One could argue drugs, materials, or devices described in this article. that the facial nerve grafting performed as part of this procedure has some advantages in the long run as it provides some degree of facial nerve COMMENT recovery, albeit incomplete. Whether the technique utilized provides measurable facial nerve improvement from a functional and cosmetic he authors present a video demonstrating surgical management of perspective over less aggressive strategies could be debated. An alternative a glomus jugular tumor (GJT). The case is nicely presented with strategy perhaps at least worthy of mention would be SRS followed by less appropriate imaging, clinical history, surgical videos, relevant cadaveric invasive facial reanimation procedures. All this issues aside, the authors anatomical dissections, and video of the patient including facial nerve are to be congratulated on excellent technique, and a “how to do it” video function before, immediately after, and at 6-month follow-up.
