“…This connection was subsequently mentioned in articles by Gasser (1967), Baumel (1974), Shimada et al (1994), May (2000), and Hwang et al (2007a,b). Hwang et al (2007a,b) reported interconnections between the marginal mandibular branch of the facial nerve and mental nerve in 100% of cases. Similarly, Shimada et al (1994) found the same communication as well as an additional one between the mental nerve and the buccal branch of the facial nerve.…”

The facial nerve (CN VII) nerve follows a torturous and complex path from its emergence at the pontomedullary junction to its various destinations. It exhibits a highly variable and complicated branching pattern and forms communications with several other cranial nerves. The facial nerve forms most of these neural intercommunications with branches of all three divisions of the trigeminal nerve (CN V), including branches of the auriculotemporal, buccal, mental, lingual, infraorbital, zygomatic, and ophthalmic nerves. Furthermore, CN VII also communicates with branches of the vestibulocochlear nerve (CN VIII), glossopharyngeal nerve (CN IX), and vagus nerve (CN X) as well as with branches of the cervical plexus such as the great auricular, greater, and lesser occipital, and transverse cervical nerves. This review intends to explore the many communications between the facial nerve and other nerves along its course from the brainstem to its peripheral branches on the human face. Such connections may have importance during clinical examination and surgical procedures of the facial nerve. Knowledge of the anatomy of these neural connections may be particularly important in facial reconstructive surgery, neck dissection, and various nerve transfer procedures as well as for understanding the pathophysiology of various cranial, skull base, and neck disorders.

“…The afferent activity would be conducted by fibres in the trigeminal nerve for the former, and in Ruffini‐like afferent fibres in the facial nerve that cross into the trigeminal nerve at the many distal anastomoses that have been described (Hwang et al . ; Cattaneo & Pavesi, ). This was sufficient to produce LAI and PAS.…”

“…Previously Pilurzi et al (2013) argued that stimulation of the facial nerve (a pure motor nerve) generated afferent activity by evoking muscle twitches that were detected by mechanoreceptors in the overlying skin (Edin & Johansson, 1995) and/or by activation of Ruffini-like receptors that have recently been described in human facial muscles (Cobo et al 2017a,b). The afferent activity would be conducted by fibres in the trigeminal nerve for the former, and in Ruffini-like afferent fibres in the facial nerve that cross into the trigeminal nerve at the many distal anastomoses that have been described (Hwang et al 2007;Cattaneo & Pavesi, 2014). This was sufficient to produce LAI and PAS.…”

Key pointsr Previous studies investigating the effects of somatosensory afferent inputs on cortical excitability and neural plasticity often used transcranial magnetic stimulation (TMS) of hand motor cortex (M1) as a model, but in this model it is difficult to separate out the relative contribution of cutaneous and muscle afferent input to each effect. r In the face, cutaneous and muscle afferents are segregated in the trigeminal and facial nerves, respectively. We studied their relative contribution to corticobulbar excitability and neural plasticity in the depressor anguli oris M1.r Stimulation of trigeminal afferents induced short-latency (SAI) but not long-latency (LAI) afferent inhibition of face M1, while facial nerve stimulation evoked LAI but not SAI. Plasticity induction was observed only after a paired associative stimulation protocol using the facial nerve.r Physiological differences in effects of cutaneous and muscle afferent inputs on face M1 excitability suggest they play separate functional roles in behaviour. AbstractThe lack of conventional muscle spindles in face muscles raises the question of how sensory input from the face is used to control muscle activation. In 16 healthy volunteers, we probed sensorimotor interactions in face motor cortex (fM1) using short-afferent inhibition (SAI), long-afferent inhibition (LAI) and LTP-like plasticity following paired associative stimulation (PAS) in the depressor anguli oris muscle (DAO). Stimulation of low threshold afferents in the trigeminal nerve produced a clear SAI (P < 0.05) when the interval between trigeminal stimulation and transcranial magnetic stimulation (TMS) of fM1 was 15-30 ms. However, there was no evidence for LAI at longer intervals of 100-200 ms, nor was there any Giovanna Pilurzi (on the left) obtained her PhD in neurophysiology at the University of Sassari. She did her residency fellowship in Neurology at the University of Sassari. She works as neurologist at Fidenza Hospital, where she is mainly involved in the clinical neurophysiology lab. Her research activity was focused on the study of corticobulbar motor control and plasticity in healthy humans and cranial dystonia. Francesca Ginatempo (on the right) obtained her PhD in neuroscience at the University of Sassari. She is now a post-doc at University of Sassari. Since the beginning of her research activity she has investigated the voluntary and emotional control of facial muscles both in physiological conditions as well as in neurological patients G. Pilurzi and F. Ginatempo contributed equally to this work. effect of PAS. In contrast, facial nerve stimulation produced significant LAI (P < 0.05) as well as significant facilitation 10-30 minutes after PAS (P < 0.05). Given that the facial nerve is a pure motor nerve, we presume that the afferent fibres responsible were those activated by the evoked muscle twitch. The F-wave in DAO was unaffected during both LAI and SAI, consistent with their presumed cortical origin. We hypothesize that, in fM1, SAI is evoked by activity in low th...

Anastomoses between lower cranial and upper cervical nerves

Descriptions of the anatomy of the neural communications among the cranial nerves and their branches is lacking in the literature. Knowledge of the possible neural interconnections found among these nerves may prove useful to surgeons who operate in these regions to avoid inadvertent traction or transection. We review the literature regarding the anatomy, function, and clinical implications of the complex neural networks formed by interconnections among the lower cranial and upper cervical nerves. A review of germane anatomic and clinical literature was performed. The review is organized in two parts. Part I concerns the anastomoses between the trigeminal, facial, and vestibulocochlear nerves or their branches with any other nerve trunk or branch in the vicinity. Part II concerns the anastomoses among the glossopharyngeal, vagus, accessory and hypoglossal nerves and their branches or among these nerves and the first four cervical spinal nerves; the contribution of the autonomic nervous system to these neural plexuses is also briefly reviewed. Part I is presented in this article. An extensive anastomotic network exists among the lower cranial nerves. Knowledge of such neural intercommunications is important in diagnosing and treating patients with pathology of the skull base.
