Craniofacial surgery and anterior skull base surgical techniques require an intimate knowledge of periorbital structures. The medial orbital anatomy is especially important for midline approaches to nasion encephalocele, midline trauma, surgery for hypertelorism as well as midline approaches to anterior skull base lesions. The medial canthal tendon is of primary importance in anchoring the eyelid medially in a cosmetic and functional fashion. This review will summarize the anatomic features of the medial canthus and its surrounding structures, including vascular and muscular components. The intimate relationship of the three components of the medial canthal tendon to the nasal lacrimal apparatus is emphasized. Techniques to prevent injury as well as to repair abnormalities in this area will be discussed.
颅面外科手术和前颅底手术技术需要对眶周结构有深入了解。眶内侧解剖结构对于鼻根脑膨出、中线创伤、眶距增宽症手术以及前颅底病变的中线入路尤为重要。内眦韧带在以美观和功能的方式将眼睑内侧固定方面起着至关重要的作用。本综述将总结内眦及其周围结构的解剖特征，包括血管和肌肉成分。强调了内眦韧带的三个组成部分与鼻泪器的密切关系。还将讨论预防该区域损伤以及修复异常的技术。
