颈淋巴结清扫术（ND）是治疗头颈部恶性肿瘤颈淋巴结转移的重要手段。自功能性ND（FND）的引入以来，已经进行了各种修改，以减少自由基ND的不利影响。最近，许多研究者记录了保留脊髓副神经（SAN）和/或胸锁乳突肌的FND病例，这有助于改善ND后的生活质量。对于这种类型的ND，必须特别注意识别SAN和颈内静脉（IJV）。我们在科比大学医院耳鼻咽喉头颈外科进行了123例ND。通过回顾性分析相关的医院病历和手术记录，收集了所有接受ND的患者的数据。（3.3%），观察到SAN通过有窗IJV的异常，虽然这种异常很少见，头颈外科医生应该注意到SAN和IJV之间的这种异常关系，以避免对这些结构的意外损伤在ND期间。
Neck dissection (ND) is an important technique for the treatment of cervical lymph node metastasis in patients with head and neck cancer. Since the introduction of functional ND (FND), various modifications have been made to reduce the adverse effects of radical ND. Recently, many investigators have documented cases of FND with preservation of the spinal accessory nerve (SAN) and/or the sternocleidomastoid muscle, which have contributed to improve the quality of life following ND. For this type of ND, special attention must be paid to identify the SAN and the internal jugular vein (IJV).We performed 123 NDs over 2 years at the Department of Otolaryngology, Head and Neck Surgery, Kobe University Hospital. We collected data of all patients who underwent NDs by retrospectively reviewing the relevant hospital medical records and operative notes.In 4 out of 123 NDs (3.3%), an anomaly of the SAN passing through the fenestrated IJV was observed.Although this anomaly is rare, head and neck surgeons should be aware of this anomalous relationship between the SAN and the IJV in order to avoid accidental injury to these structures during ND.
