The purpose of this study is to describe a spectrum of surgical approaches to orbital dermoid cysts, influenced by the anatomic location of the expanded cyst wall and other factors.
In this retrospective case series, we reviewed cases of dermoid cysts surgically excised during a 39-year period (1977-2016). Cysts were categorized according to the location of the expanded cyst wall and other considerations. The impact of these factors on surgical management was determined.
We identified six dermoid cyst growth patterns based on the anatomic location of the expanded cyst wall that influence the surgical approach: to the frontozygomatic suture (FZS), to the FZS, to the FZS and other lateral wall sutures, the FZS and other lateral wall sutures, , and from the orbit to the skin. Two additional factors influencing surgical methodology included satellite inflammatory pseudocysts and recurrence after surgical resection.
Orbital dermoid cysts are not monolithic lesions. Functional and aesthetic outcomes can benefit from considering the anatomic pattern of cyst wall expansion and other factors in their surgical management.
本研究旨在描述受膨出囊壁的解剖位置和其他因素影响的眼眶皮样囊肿的一系列手术入路。
在这项回顾性病例系列研究中，我们回顾了在 39 年期间（1977 年至 2016 年）手术切除的皮样囊肿病例。根据膨出囊壁的位置和其他考虑因素对囊肿进行分类。确定了这些因素对手术管理的影响。
我们根据膨出囊壁的解剖位置确定了六种影响手术入路的皮样囊肿生长模式：至额颧缝（FZS）、至 FZS、至 FZS 及其他外侧壁缝线、至 FZS 及其他外侧壁缝线、至眶缘至皮肤。另外两个影响手术方法的因素包括卫星炎性假性囊肿和手术切除后复发。
眼眶皮样囊肿并非单一病变。考虑囊壁膨出的解剖模式和其他因素对其手术治疗，可以改善功能和美容效果。
