The purpose of this paper was to report the incidence of orbital haematoma formation following the repair of orbital fractures with silicone, polytetrafluorethylene (PTFE), and poly-L-lactic acid/hydroxyapatite (PLLA/HA) implants. This retrospective review examined 234 patients (235 sides) who underwent repair of orbital wall fractures over a six-year period. Of these, 36 patients received a silicone sheet; 49 patients received a silicone sheet with superimposed PTFE implant; and 149 patients (150 sides) received PTFE with or without an underlying PLLA/HA implant. Orbital haematomas were documented in 13 out of 36 patients (36.1%) who underwent fracture repair with a silicone sheet; seven out of 49 patients (14.3%) who had a silicone sheet with a superimposed PTFE implant; and three out of 150 sides (2.0%) with PTFE with or without underlying PLLA/HA. The difference in incidence of orbital haematoma formation was significant among the groups (p < 0.001, Pearson's chi squared test). In the silicone sheet group, haematomas formed within two weeks of surgery in 11 patients (84.6%). In the silicone sheet with superimposed PTFE implant group, five patients (71.4%) developed orbital haematomas no earlier than after two weeks postoperatively. This study showed that the incidence of orbital haematoma formation following orbital fracture repair is different among the implant materials. The use of PTFE and PLLA/HA implants may minimise this complication.
本文旨在报告使用硅酮、聚四氟乙烯（PTFE）和聚 L-乳酸/羟基磷灰石（PLLA/HA）植入物修复眼眶骨折后眶内血肿形成的发生率。这项回顾性研究检查了 234 例（235 侧）在六年期间接受眼眶壁骨折修复的患者。其中，36 例患者接受了硅酮片；49 例患者接受了硅酮片与重叠 PTFE 植入物；149 例患者（150 侧）接受了 PTFE 联合或不联合底层 PLLA/HA 植入物。在接受硅酮片修复骨折的 36 例患者中（36.1%），有 13 例（13.0%）发生了眶内血肿；在接受硅酮片与重叠 PTFE 植入物的 49 例患者中（14.3%），有 7 例（7.1%）发生了眶内血肿；在接受 PTFE 联合或不联合底层 PLLA/HA 植入物的 150 例患者中（2.0%），有 3 例（3.0%）发生了眶内血肿。各组之间眶内血肿形成的发生率差异有统计学意义（p<0.001，Pearson's chi squared 检验）。在硅酮片组中，11 例（84.6%）患者在术后两周内形成血肿；在硅酮片与重叠 PTFE 植入物组中，5 例（71.4%）患者在术后两周后才发生眶内血肿。本研究表明，眼眶骨折修复后眶内血肿形成的发生率因植入物材料而异。使用 PTFE 和 PLLA/HA 植入物可最大程度减少这种并发症。
