The medial canthus is supported by several structures with a complicated 3-dimensional arrangement in a narrow space. Although the medial canthal tendon occupies a major portion of the area, the medial canthal support structures include the following entities: Horner's muscle, the medial rectus capsulopalpebral fascia including the medial check ligament, the medial horn of the levator aponeurosis, the medial horn supporting ligament, the medial horn of the lower eyelid retractors, the preseptal part of the orbicularis oculi muscle, and 3 variations of the Lockwood's ligament. We named the composite of these structures the "medial retinaculum," which is similar to the "lateral retinaculum" of the lateral canthus. Profound comprehension and consideration of the medial retinaculum warrants safe and effective surgery in the medial canthal region.
内眦由多个结构支撑，这些结构在狭小空间内呈复杂的三维排列。尽管内眦韧带占据了该区域的大部分面积，但内眦支撑结构还包括以下结构：霍纳肌、包括内侧节制韧带在内的内直肌睑囊筋膜、提上睑肌腱膜内侧角、内侧角支持韧带、下睑缩肌内侧角、眼轮匝肌的眶隔前部，以及洛克伍德韧带的3种变异。我们将这些结构的复合体命名为“内侧支持带”，它类似于外眦的“外侧支持带”。对内眦支持带的深入理解和考量有助于在内眦区域进行安全有效的手术。
