To investigate the risks of implant exposure after a combined explant-implant procedure in patients with an exposed porous orbital implant.
Twenty-four consecutive patients who had a combined explant-implant procedure of an exposed hydroxyapatite (21) or porous polyethylene (3) orbital implant from January 2000 to February 2009 were included. The patient records were reviewed; patients were interviewed by telephone and invited for a clinical examination. Histopathological examination was carried out on the removed implants. Main outcome measures were: presence of exposure of the new implant or not, patient graded satisfaction with the cosmetic result, and presence of poor motility.
None of the new implants became exposed or infected in the follow-up period of 25 [3-94] months (median [range]). The patients scored their satisfaction with the cosmetic result to a median score of 9 (range 5-10). Poor motility was present in six of 17 patients. Micro-organisms were identified in three removed implants and signs of inflammation were present in 20 removed implants.
If a decision of implant removal has been made, it is safe to replace the implant at the same procedure in sockets without profound signs of infection. The procedure carries a possible risk of poor motility.
研究在多孔性眶植入物暴露的患者中进行联合植入物取出-植入物手术的植入物暴露风险。
自 2000 年 1 月至 2009 年 2 月，共纳入 24 例连续患者，对其进行了多孔性羟磷灰石（21 例）或多孔性聚乙烯（3 例）眶植入物的联合植入物取出-植入物手术。回顾患者的病历记录；通过电话对患者进行访谈，并邀请其进行临床检查。对取出的植入物进行组织病理学检查。主要观察指标：新植入物是否暴露或感染、患者对美容效果的满意度评分（分级），以及是否存在运动不良。
在 25 个月（3-94 个月，中位数[范围]）的随访期间，无新植入物暴露或感染。患者对美容效果的满意度评分为中位数 9 分（5-10 分）。17 例患者中有 6 例存在运动不良。3 例取出的植入物中发现了微生物，20 例取出的植入物中存在炎症迹象。
如果决定取出植入物，则在无明显感染迹象的情况下，在同一手术中于同一骨窝中更换植入物是安全的。该手术存在运动不良的潜在风险。
