目的 :研究用羟基磷灰石义眼座作为眶内植入材料 ,并在不同条件下所需施行的不同术式。方法 :对 32例患者施行HA植入术 ,其中I期植入 2 8例 ,II期植入 4例。随访 1～ 2年。结果 :32例手术中 ,2 5例I期愈合 ,安装薄形义眼片后 ,活动度在 15°～ 2 0° 15例 ,10°～ 15° 10例 ,10°以下 7例。 7例出现了并发症 ,男 5例 ,女 2例 ;I期植入 5例 ,II期植入 2例。 6例为结膜裂开 ,1例为结膜肉芽肿。结论 :羟基磷灰石义眼座是目前较理想的眶内植入材料 ,而且手术方法的改良 ,使手术有良好的效果。
Objective: To study the hydroxyapatite orbital prosthesis as an orbital implant material, and under different conditions required for the implementation of different surgical procedures. Methods: 32 patients underwent HA implantation, including 28 cases in stage I and 4 cases in stage II. Follow-up 1 to 2 years. Results: Among the 32 cases, 25 cases were healed in the first stage. After the installation of thin prosthetic eyelid, the activity ranged from 15 ° to 20 ° in 15 cases, 10 ° to 15 ° in 10 cases and 10 ° in 7 cases. Complications occurred in 7 cases, 5 males and 2 females; 5 cases were implanted in stage I and 2 cases were implanted in stage II. 6 cases of conjunctival rupture, 1 case of conjunctival granuloma. Conclusion: hydroxyapatite orbital prosthesis is the ideal orbital implant material, and the improvement of surgical methods, the surgery has a good effect.
