Abstract：
A primary orbital respiratory cyst is a congenital choristoma that presents in the orbit and with different signs and symptoms depending on the location, which might also change the surgical approach. The aim of this report is to describe 2 new cases of primary respiratory epithelial cysts and to review the literature on presentation, management, and risk factors with different surgical approaches and complications. Two cases presenting with gradually increased proptosis had a confirmed diagnosis of a respiratory epithelial cyst. CT and MRI imaging revealed a thin-walled intraconal cystic lesion. Complete surgical removal was not possible and an incisional biopsy of the wall was performed. Rarely, orbital respiratory epithelium cysts are primary lesions. The high risk of breaking the capsule during surgery and the presence of residual epithelial cells within the orbit may cause cyst\'s recurrence. Indeed, we recommend careful attention during dissection maneuvers and a long-term follow-up.
摘要：
原发性眼眶呼吸囊肿是一种先天性脉络膜瘤，存在于眼眶中，并根据位置有不同的体征和症状。这也可能改变手术方法。本报告的目的是描述2例原发性呼吸道上皮囊肿的新病例，并回顾文献介绍，管理,不同手术方式及并发症的危险因素。2例突眼逐渐增加的病例已确诊为呼吸道上皮囊肿。CT和MRI成像显示薄壁腔内囊性病变。无法完全手术切除，并进行了壁的切开活检。很少,眼眶呼吸道上皮囊肿是原发性病变。在手术期间破裂囊的高风险和眼眶内残留上皮细胞的存在可能导致囊肿的复发。的确,我们建议在解剖操作和长期随访期间小心注意。
