眼眶骨折是外伤性疾病常见的眼眶并发症，部分需要行眼眶骨折修复手术治疗。不同材料的植入物，是影响手术效果和预后的重要因素之一。植入物的选择国内外至今尚未有统一的标准。目前临床上使用的植入材料多为异质材料，有不可吸收材料和可吸收材料两类。不可吸收材料使用最多的是钛网和高密度多聚乙烯(Medpor)。可吸收材料主要是各类高分子聚合物。这两类材料在临 床的使用过程中都表现出了不同的优缺点，通过查阅近5年的相关报道，对比这两类材料的优缺点，可以为临床医生的选择提供一些参考。

Orbital fracture is a common orbital complication of traumatic diseases, and some of them need to be treated by orbital fracture repair surgery. Implants of different materials are one of the important factors affecting the surgical outcome and prognosis. There is no uniform standard for the selection of implants at home and abroad. At present, most of the implant materials used in clinical practice are heterogeneous materials, including non-absorbable materials and absorbable materials. The most commonly used non-absorbable materials are titanium mesh and high-density polyethylene (Medpor). Absorbable materials are mainly all kinds of macromolecular polymers. These two types of materials have shown different advantages and disadvantages in clinical. By reviewing the relevant reports recent 5 years, and comparing the advantages and disadvantages of these two types of materials, we can provide some references for clinicians to choose from.

眶尖部肿瘤为眼科罕见疾病，但因其所处位置特殊，对机体，特别是视神经功能危害极大，错误的诊断、不规范合理的治疗不仅不能解决问题，甚至会对机体造成严重的不可挽回的损害。目前针对眶尖部肿瘤的诊断、治疗多建立在医生的主观认知与经验的基础上，尚未达成共识。本文通过分析眶尖部肿瘤的临床特点，结合以往漏诊、误诊、误治的临床案例，阐述眶尖肿瘤正确诊断的关键要点；同时，结合不同临床案例，客观分析治疗方案，尤其是手术方式、路径，为眶尖部肿瘤的合理化治疗提供依据，以期规范眶尖部肿瘤的诊断和治疗，提高治疗成功率。

Although orbital apical tumor is a rare ophthalmic disease, its special location can cause great harm to the body, especially to the function of the optic nerve. Misdiagnosis and improper treatment are not only unable to solve the problem, but also irretrievably harmful to the body. At present, there is no consensus on the diagnosis and treatment of orbital apical tumors, which are mostly based on subjective cognition and experience of doctors. In this paper, the clinical characters of orbital apical tumors were analyzed through the past clinical cases of misdiagnosis and mistreatment, and the key points of proper diagnosis of orbital apical tumors were expounded. Meanwhile, by combining with different clinical cases, the treatment plans, especially the surgical approaches, were analysed to provide a basis for the appropriate treatment of orbital apical tumors, in order to standardize the diagnosis and treatment of orbital apex tumor, and improve the success rate of treatment.
