Excision of Scarpa's Ganglion

Neural connections between the nervus intermedius and the facial and vestibulocochlear nerves in the cerebellopontine angle: an anatomic study

“…Regarding deep connections between the facial and vestibulocochlear nerves, Paturet [18] found connections between the genu of the facial nerve and Scarpa's ganglion. Cruveilhier [5] also described nerve connections between the facial and vestibulocochlear nerves and this was confirmed by later reports [8][9][10]. Hovelacque [11] cited Arnold two connections at the level of the porus acousticus, 1 lateral (from the facial nerve to the vestibular ganglion, with containing sympathetic fibers, 1 medial that might belong to the nervus.…”

Electrical stimulation of cranial nerves in cognition and disease

“…These connections form at different points along the fiber pathways. For instance, the vestibular end-organ has been shown to respond to acoustic stimulation in guinea pigs [581] while the nervus intermedus of the facial nerve shows connections to the vestibular nerve at the Scarpa's ganglion [582]. Depending on where along cranial nerves these connections are formed, the effect that anastomoses will have on the outcome of electrical stimulation will differ.…”

Three‐dimensional imaging of the human internal acoustic canal and arachnoid cistern: a synchrotron study with clinical implications

“…Anastomoses between the facial and vestibular nerves are known to exist in the IAC (Paturet, ; House, ; Fisch, ; Silverstein, ; Rubinstein et al. ; Ryu et al.…”
