Two cases of orbital tumor are presented, and the surgical technique by means of an endoscopic transnasal approach is discussed. In Case 1, a non-vascular, benign tumor was located inside the orbit, and it was able to be completely removed, without any complications. The tumor in Case 2 was also located inside the orbit, but it was determined to be a hemangioma based on the intraoperative pathology. To avoid eye complications arising from performance of the surgery in the presence of bleeding, it was decided to widely open the orbital lamina papyracea and periosteum, and perform only orbital decompression. The eye symptoms disappeared in both patients. Endoscopic transnasal surgery is indicated for benign orbital tumors that are medially located in the orbit. It can be thought that the eye symptoms can be alleviated by avoiding orbital pressure, regardless of whether-based on the intraoperative pathology-the tumor is completely removed or not.
本文介绍了两例眼眶肿瘤病例，并讨论了经鼻内镜手术技术。病例1中，眼眶内有一个无血管的良性肿瘤，能够被完全切除，且无任何并发症。病例2中的肿瘤也位于眼眶内，但根据术中病理检查确定为血管瘤。为避免手术过程中出血引发眼部并发症，决定广泛打开眶纸板和骨膜，仅进行眼眶减压。两名患者的眼部症状均消失。经鼻内镜手术适用于位于眼眶内侧的良性眼眶肿瘤。可以认为，无论基于术中病理肿瘤是否被完全切除，通过避免眼眶压力都可缓解眼部症状。
