目的 外侧开眶术是治疗眼眶中、後部肿瘤及泪腺肿瘤的一种标准术式,本文主要讨论现代外侧开眶术手术方法及适应症。方法 采用标准外侧开眶,“S”形外侧开眶和外侧结合内侧开眶术三种术式共做70例眼眶肿瘤。结果采用标准外侧开眶适合于视神经以下肿瘤的切除(38例),“S”形外侧开眶适合于视神经以上肿瘤的切除(28例),外侧结合内侧开眶适合于视神经周围广泛肿瘤的切除(4例),均获较好效果。结论 根据肿瘤的性质,位置和范围采用不同术式的外侧开眶。包括眶上、下缘的外侧开眶使术野明显扩大,提高了手术的成功率。
The purpose of lateral orbital surgery is the treatment of orbital tumors, lacrimal gland tumors and a standard surgical technique, this article discusses the modern lateral orbital surgery methods and indications. Methods A total of 70 cases of orbital tumors were treated with standard lateral orbital, “S” lateral orbital and lateral medial orbital surgery. Results The standard lateral orbital was suitable for excision of the tumors below the optic nerve (38 cases). The S-shaped lateral orbit was suitable for the resection of tumors above the optic nerve (28 cases). The lateral medial orbital opening was suitable for the resection of a wide range of tumors around the optic nerve (4 cases), were better results. Conclusion According to the nature of the tumor, the location and scope of the use of different surgical lateral fossa. Including the supraorbital, the lower edge of the lateral orbital surgery field was significantly expanded to improve the success rate of surgery.
