摘要

目的本研究旨在确定枕动脉胸锁乳突肌分支（SBOA）是否可用于可靠预测颈部解剖时脊髓附属神经（SAN）的位置。主要结果是 SBOA 沿轴向和垂直平面插入胸锁乳突肌 (SCM) 距离 SAN 5 毫米以内的频率。对基线特征与这些结果的相关性进行了测试。结果对54名患者的87例颈部解剖进行了评估。在86/87例（98.9%）和85/86例（98.8%）的病例中，SBOA在轴向插入SAN的5毫米范围内，在纵向插入SCM的5毫米范围内。SBOA插入SCM的平均深度为浅表0.6毫米（+/- 1.4），尾部0.6毫米（+/- 2.5）。与深部相比，66/87 例（75.9%）的 SBOA 插入神经浅部；与头侧相比，50/86 例（58.1%）的 SBOA 插入神经尾部。结论 SBOA 与 SAN 关系密切，可作为一个可靠的标志，帮助在颈部解剖时保留神经。

Anatomic relationship of the sternocleidomastoid branch of the occipital artery with the spinal accessory nerve

Purpose

This study was designed to determine if the sternocleidomastoid branch of the occipital artery (SBOA) may be used to reliably predict the location of the spinal accessory nerve (SAN) during neck dissections.

Materials and methods

A retrospective cohort study was performed on patients undergoing neck dissections involving level II. The primary outcome was the frequency in which the SBOA inserted into the sternocleidomastoid muscle (SCM) within 5mm from the SAN along axial and vertical planes. Baseline characteristics were tested for association with these outcomes.

Results

87 neck dissections on 54 patients were evaluated. The SBOA inserted into the SCM within 5mm of the SAN in 86/87 cases (98.9%) axially and 85/86 cases (98.8%) vertically. The SBOA inserted into the SCM and average of 0.6mm (+/- 1.4) superficial and 0.6mm (+/- 2.5) caudal. The SBOA inserted superficial to the nerve in 66/87 cases (75.9%) compared to deep, and caudal to the nerve in 50/86 cases (58.1%) compared to cephalad. There was no association with age, sex, body mass index, laterality, head and neck radiation, or level II nodal disease.

Conclusions

The SBOA is closely associated with the SAN and may serve as a reliable landmark to help preserve the nerve during neck dissections.

期刊介绍： This large-size, atlas-format journal presents detailed illustrations of new surgical procedures and techniques in otology, rhinology, laryngology, reconstructive head and neck surgery, and facial plastic surgery. Feature articles in each issue are related to a central theme by anatomic area or disease process. The journal will also often contain articles on complications, diagnosis, treatment or rehabilitation. New techniques that are non-operative are also featured.
