This report defines the C2 and C3 pain dermatomes by the distribution of: the hypalgesia clearing after surgical root decompression; the dysaesthesias produced by electrical root stimulation; and the hypalgesia produced by anaesthetic root block. The C2 pain dermatome, so defined, consists of an occipital parietal area 6-8 cm wide, ascending paramedially from the subocciput to the vertex. The C3 pain dermatome is a craniofacial area including the scalp around the ear, the pinna, the lateral cheek over the angle of the jaw, the submental region and the lateral and anterior aspects of the upper neck. These C2 and C3 pain dermatomes do not overlap and are smaller than the C2 and C3 tactile dermatomes described in the literature.
本报告通过以下分布情况定义了C2和C3疼痛皮节：手术神经根减压后痛觉减退消失的区域；神经根电刺激产生的感觉异常区域；以及麻醉性神经根阻滞产生的痛觉减退区域。如此定义的C2疼痛皮节由一个宽6 - 8厘米的枕顶区域组成，从枕下向内侧上升至头顶。C3疼痛皮节是一个颅面部区域，包括耳周头皮、耳廓、下颌角上方的外侧脸颊、颏下区域以及上颈部的外侧和前侧。这些C2和C3疼痛皮节不重叠，且比文献中描述的C2和C3触觉皮节小。
