This article elucidates the anatomical details of the course and territory of the supraorbital (SO) and supratrochlear (ST) nerves. Possible applications of the SO and ST nerves for sensory nerve transfer are also examined.
The dissection of 3 fresh cadaver heads (6 hemifaces) was performed. In each hemiface, the ST and SO nerves were identified. The following data were recorded: 1) number of branches, 2) skin boundaries, 3) communicative branches, and 4) branch length. The feasibility of specific nerve-transfer procedures was also examined.
In 4 hemifaces the SO nerve exited from the SO notch and in 2 hemifaces from the SO foramen. The position was lateral to the midline, with a mean distance of 1.93 cm. In all dissections, a maximum of 4 SO branches (range 2-4) were identified. The ST nerve exited the orbital rim medial to the SO nerve, and lateral to the midline with a mean distance of 0.866 cm. The mean distance between the SO and ST nerves at the level of the SO rim was 1.06 cm. In 5 of 6 hemifaces, several sub-branches emerged from the main trunk of the ST nerve. In 1 hemiface the ST nerve was divided in 2 main branches.
The data presented in the current study are in agreement with previous anatomical studies. Both ST and SO nerves can be used as sensory nerve donors in the head and neck area for numerous expanding applications.
本文阐述了眶上（SO）和滑车上（ST）神经的解剖细节。还研究了 SO 和 ST 神经用于感觉神经转移的可能应用。
对 3 具新鲜尸体头颅（6 个半面）进行解剖。在每个半面中，识别出 ST 和 SO 神经。记录以下数据：1）分支数量，2）皮肤边界，3）通讯分支，4）分支长度。还检查了特定神经转移程序的可行性。
在 4 个半面中，SO 神经从 SO 切迹中穿出，在 2 个半面中从 SO 孔中穿出。位置在中线外侧，平均距离为 1.93cm。在所有解剖中，最多可识别出 4 个 SO 分支（范围 2-4）。ST 神经从 SO 神经的眶缘内侧穿出，位于中线外侧，平均距离为 0.866cm。SO 神经和 ST 神经在 SO 缘水平的平均距离为 1.06cm。在 6 个半面中的 5 个中，ST 神经的主干上出现了几个分支。在 1 个半面中，ST 神经分为 2 个主要分支。
目前研究的数据与先前的解剖学研究一致。ST 和 SO 神经都可以作为头颈部的感觉神经供体，用于许多扩展的应用。
