■尚未揭示肌内神经的整体分布模式以及深颈肌肉中纺锤体丰度最高的区域。这项研究旨在揭示神经肌肉区室化,并定位深层颈部肌肉中最高肌肉纺锤体丰度(CRHMSA)区域中心的体表位置和深度。
■这项研究包括36名成年尸体(57.7±11.5年)。连接颈静脉凹口和下巴尖端的最低点的曲线被指定为纵向参考线(线L),将颈静脉切迹最低点与肩峰相连的曲线指定为水平基准线(H线)。改良的Sihler染色,采用苏木精-伊红染色和计算机断层扫描来确定CRHMSA在颈部前表面上的投影点(P)。点P投影到H和L线上的位置(PH和PL),以及每个CRHMSA的深度,使用Syngo系统确定穿刺角度。
■将后半角质层和长角质层分为两个神经肌肉区室,而前肌和颈长肌分为三个神经肌肉区。中斜角肌可以分为五个神经肌肉区室。斜角肌CRHMSA的PH(前,Medius,和后部),长头骨炎和颈长肌,位于H线的36.27、39.18、47.31、35.67和42.71%,分别。PL位置分别为L线的26.53、32.65、32.73、68.32和51.15%,分别。CRHMSA的深度为2.47厘米,2.96厘米,2.99厘米,3.93cm,和3.17厘米,分别,穿刺角度为87.13°,85.92°,88.21°,58.08°,和77.75°,分别。
■目前的研究表明,深颈肌可以分为神经肌肉区;我们建议将这些CRHMSA的位置作为注射肉毒杆菌毒素A治疗深颈肌张力障碍的最佳目标。
UNASSIGNED: The overall distribution pattern of intramuscular nerves and the regions with the highest spindle abundance in deep cervical muscles have not been revealed. This study aimed to reveal neuromuscular compartmentalization and localize the body surface position and depth of the center of the region of highest muscle spindle abundance (CRHMSA) in the deep cervical muscles.
UNASSIGNED: This study included 36 adult cadavers (57.7 ± 11.5 years). The curved line joining the lowest point of the jugular notch and chin tip was designated as the longitudinal reference line (line L), and the curved line connecting the lowest point of the jugular notch and acromion was designated as the horizontal reference line (line H). Modified Sihler\'s staining, hematoxylin-eosin staining and computed tomography scanning were employed to determine the projection points (P) of the CRHMSAs on the anterior surfaces of the neck. The positions (PH and PL) of point P projected onto the H and L lines, and the depth of each CRHMSA, and puncture angle were determined using the Syngo system.
UNASSIGNED: The scalenus posterior and longus capitis muscles were divided into two neuromuscular compartments, while the scalenus anterior and longus colli muscles were divided into three neuromuscular compartments. The scalenus medius muscle can be divided into five neuromuscular compartments. The PH of the CRHMSA of the scalenus muscles (anterior, medius, and posterior), and longus capitis and longus colli muscles, were located at 36.27, 39.18, 47.31, 35.67, and 42.71% of the H line, respectively. The PL positions were at 26.53, 32.65, 32.73, 68.32, and 51.15% of the L line, respectively. The depths of the CRHMSAs were 2.47 cm, 2.96 cm, 2.99 cm, 3.93 cm, and 3.17 cm, respectively, and the puncture angles were 87.13°, 85.92°, 88.21°, 58.08°, and 77.75°, respectively.
UNASSIGNED: Present research suggests that the deep cervical muscles can be divided into neuromuscular compartments; we recommend the locations of these CRHMSA as the optimal target for administering botulinum toxin A injections to treat deep cervical muscle dystonia.
