目的探讨球形多孔羟基磷灰石义眼台植入术后结膜囊形态变化,以指导义眼安装。方法67例眼球摘除术患者同期植入直径18mm球形多孔羟基磷灰石义眼台,术后15天按常规方法制作并安装义眼片,用卡尺、直尺对义眼片各项值进行测量,间接反映术后结膜囊各项数值。结果义眼片各项测量值均较正常结膜囊数值小。结论分析术后结膜囊形态容积变化,为合理选择义眼台的大小和制作安装合适义眼片,提供一定的临床指导。
Objective To investigate the morphological changes of conjunctival sac after spherical porous hydroxyapatite orbital implants in order to guide the installation of the eye. Methods 67 cases of enucleation patients were enrolled in this study. The diameter of 18mm spherical porous hydroxyapatite prosthesis was implanted in the same period, and the prosthetic eye pieces were made and fitted 15 days after the operation. The values of eyelid pieces were measured by calipers and rulers , Indirectly reflect the value of postoperative conjunctival sac. Results Eyelid films measured values were smaller than the normal value of conjunctival sac. Conclusions The change of morphology and volume of conjunctival sac after operation is analyzed. It provides some clinical guidance for the reasonable selection of the size and installation of appropriate eyelid.
