视网膜母细胞瘤术后羟基磷灰石义眼座一期植入探讨

Clinical exploration of the orbital lmplant at its early rtage after retinoblastoma operation

目的:探讨儿童视网膜母细胞瘤(retinoblastoma,RB)眼球摘除术后羟基磷灰石义眼座一期眶内植入的可行性。方法:对21例(21眼)RB患儿,施行眼球摘除联合无包裹羟基磷灰石义眼座一期眶内植入手术。结果:随访3个月至5年,义眼座活动度良好,外形满意,眼眶及面部发育正常。2例眼座暴露,其中1例暴露4 mm×5 mm,应用重组人表皮细胞生长因子滴眼液治疗,1例暴露9 mm×9 mm,给予手术介入+羊膜覆盖,均治愈。结论:RB术后羟基磷灰石义眼座一期植入效果好,有助于儿童眼眶及面部发育,不影响放射治疗及CT检查,最常见并发症为眼座暴露。

Objective：To explore the possibility of the hydroxyapatite orbital implants after children-retinoblastoma-eyeball-excision operations. Methods：For 21 cases（21 eyes）with retinoblastoma,enucleation was executed with the exposed hydroxyapatite orbital implant at its early stage. Results：Three-month to five-year subsequent visits showed that the orbitals acted well in good shape and developed desirably in the orbit and the face.For the two cases with orbitals exposure.One exposed 4 mm×5 mm,cured with the treatment of restoratin-superficial-skin-gowth-factor eyeliquid,the other exposed 9 mm×9 mm,cured with the operation of amnion cover. Conclusions：The hydroxyapatite orbital implants had satisfactory effects after retinoblastma operations,with good help for children′s orbits and faces growth,with little influence on radiotherapy or CT examination.The most common complication is the eye exposure.
