目的探讨Medpor义眼座植入同期放置钛钉治疗眼球摘除术后眼眶凹陷畸形的有效性和可行性。方法眼球摘除同期置入Medpor义眼座患者80例,随机分为钛钉Ⅰ期置入组和Ⅱ期置入组,每组各40例。比较两组患者术中、术后出现的并发症和患者对义眼活动度和外观的满意程度。结果40例Ⅰ期置入患者术中有37例在术后2～6周时钛钉尾端自发性暴露,只有3例患者需要剪开结膜使钛钉尾端暴露。术后出现并发症者共37例,占46%：其中Ⅰ期置入组17例,Ⅱ期置入组20例,两者差异无统计学意义(P=0．501)。所有患者对其外观和活动度满意,其中Ⅰ期置入组非常满意36例,比较满意4例；Ⅱ期置入组非常满意34例,比较满意6例,两者差异无统计学意义(P=0．502)。结论Medpor义眼座置入同期放置钛钉治疗眼球摘除术后眼眶凹陷畸形,是一种安全有效的手术方法,同时患者避免了再次手术的痛苦。
Objective To investigate the effectiveness and feasibility of Medpor implantation in the treatment of orbital deformity after enucleation with titanium nail. Methods Eighty cases of patients with ocular prosthesis were enrolled in the same period of enucleation. The patients were randomly divided into two groups: the first stage of titanium nail placement and the second stage of implantation. Each group had 40 cases. Comparisons were made between the two groups in terms of intraoperative and postoperative complications and the patient’s satisfaction with the degree of eye movement and appearance. Results In the 40 patients with stage Ⅰ implantation, 37 cases were spontaneously exposed at the caudal end of titanium nail at 2 to 6 weeks after operation. Only 3 cases needed to have the conjunctiva cut open to expose the caudal end of titanium nail. Postoperative complications occurred in 37 cases (46%), including 17 cases in stage I and 20 cases in stage II. There was no significant difference between the two groups (P = 0.501). All patients were satisfied with their appearance and activity. Among them, 36 cases were satisfied with stage Ⅰ implantation, 4 cases were satisfied with it. Stage Ⅱ was satisfied with 34 cases, while 6 cases were satisfactory with no significant difference (P = 0.502). Conclusion Medpor prosthesis placed in the same period placed titanium nail treatment of orbital deformity after enucleation is a safe and effective surgical method, while patients to avoid the pain of re-operation.
