SR‐PCI of the vestibulo‐facial anastomosis. (a) Cross‐sectioned right IAC near the transverse crest (TC). The arachnoid folds are seen (arrows). (b) More lateral, anastomosing fibers exist (large arrow) between the SVN and the FN. Framed area is magnified in (c). (c) Framed area shows the nerve anastomosis (large arrow) and the arachnoid (thin arrows). There is no separation of arachnoid between the two nerves above the TC. (d) Connecting fibers (arrow) between the SVN and FN at the vertical crest running toward the FN. A similar arrangement can be seen in the colored inset.
