眉区、上睑的解剖及其在上睑下垂外科中的意义

对成人尸体30侧上睑和8侧眉区的解剖学观察发现,在眉区、帽状腱膜前后鞘包绕肌层(相互交织的额肌、眼轮匝肌和皱眉肌),而后鞘通过脂肪垫牢固附着于眶上缘,并见少量额肌纤维止于眉区皮肤。在上睑眶隔多在平睑板上缘或稍下方与腱膜融合。对上睑提肌腱膜、Miiller 氏肌尤其是它们的止点作了仔细的观察和测量。讨论了上述解剖在上睑下垂外科中的意义。

Anatomy of the eyebrow and upper eyelid region and its significance in ptosis surgery

The article reports the results of the anatomic observations from dissec ring 30 upper eyelids and 8 eyebrows of adult cadavers.In the eyebrow region,the ante- rior and posterior sheaths of the galea inclose the muscle plane where the frontalis,or- bicularis and corrugator muscles are interdigitated.The posterior sheath attaches to supraorbital ridge through the brow fat pad.It was found that a few fibers of the frontalis muscle insert to the skin of the brow.In the upper eyelid,the orbital septum fuses with the aponeurosis at or just bellow the upper margin of the tarsus.The levator aponeurosis,Muller's muscle,particularly their attachements were carefully observed and measured.Finally,the application of the anatomy in the ptosis surgery is discussed.
