morphological relationship between the superior Cervical ganglion and Cervical Nerves in japanese cadaver donors
Brain and behavior, 2017Co-Authors: Kazuyuki Mitsuoka, Takeshi Kikutani, Iwao SatoAbstract:Introduction There are various communications between the superior Cervical ganglion (SCG) and the vagus and glossopharyngeal Nerves. However, little information exists concerning the origin of these sympathetic ganglion branches at the superior, middle, and inferior regions of the human SCG. The aim of this study was to describe the human SCG in a morphometric manner with the communication with cranial and Cervical Nerves and supply. Methods This study characterized 72 SCG samples from 54 elderly Japanese human cadavers (30 males, 24 females; 65–100 years old). The SCG size (length, width, and thickness) and location were measured from the jugular foramen. We also defined the communication branches of the SCG to the vagus, glossopharyngeal, Cervical, and accessory Nerves at three regions (superior, middle, and inferior regions) of the SCG. Finally, we examined the arrangement and origin of the branch communications in detail and confirmed our observations, using histological sections of the SCG. Results The SCG in all cadaver donors was detected at the C2 and C3 vertebra levels. The number of SCG branches supplied the communicating branches, such as the carotid branch, communicating branch of the vagus nerve, and glossopharyngeal nerve, were frequently detected in the superior region of the SCG (χ2 = 587.72, df = 26, p < .001). The number of ganglion cells with a large number of neurons per unit area (1 mm2) was most often found in the middle region with shrunken neurons of the SCG compared with other regions. Conclusion The communication branches of the SCG are mainly connected to the vagus and glossopharyngeal Nerves. Characterizing these branches can provide useful data for head and neck ganglion block and surgical treatments.

Spasmodic torticollis: severe compression neuropathy in rami dorsales of Cervical Nerves C1–6
Acta neuropathologica, 1992Co-Authors: J. M. Schröder, B. Huffmann, V. Braun, Hans-peter RichterAbstract:In 28 patients with spasmodic torticollis dorsal branches of the Cervical Nerves C1-6, and in 25 of these patients fascicles of the contralateral accessory nerve were investigated by light and electron microscopy. Significant changes were noted in 15 patients. The alterations were not seen or were less prominent in the 5 control cases studied for comparison. Semiquantitative evaluation of light microscopic findings revealed in 12 cases prominent and numerous Renaut bodies; in 9 cases evidence of regeneration (in 3 of these postoperatively); and in 11 cases disproportionately thin myelin sheaths in relation to axon calibers. In conjunction with endoneurial edema and thickening of the perineurium, these changes were suggestive of compression neuropathy. Whether these changes were the cause, or a side effect of the abnormal muscle contractions in spasmodic torticollis could not be elucidated. Peripheral nerve compression, however, may trigger abnormal activity in the peripheral part of the involved interneuronal circuits and may, thus, be considered as one of the many possible causes of spasmodic torticollis.

Retraction Note: Successful clavicle fracture surgery performed under selective supraclavicular nerve block using the new subclavian approach.
JA clinical reports, 2020Co-Authors: Hironobu Ueshima, Hiroshi OtakeAbstract:Cervical Nerves block cannot be performed on some patients because of the risk of phrenic nerve paralysis. To overcome this limitation, we discovered the site of selective only supraclavicular nerve block at the subclavian site. We present the case of a 62-year-old woman with clavicular fracture. We performed a selective block of the supraclavicular nerve and the fifth and sixth Cervical Nerves for the clavicle fracture surgery. We can perform selective supraclavicular nerve blocks for clavicular fracture surgery of patients who have bilateral pneumothorax.
