羟基磷灰石复合人工骨片植入联合唇黏膜移植结膜囊成形术

Reconstruction ofconjunctival sac using Hydroxyapatite composite bone chip and oral mucosa transplantation

目的探讨同期羟基磷灰石复合人工骨（HA）植入联合唇黏膜移植结膜囊成形术的手术方法及临床效果。方法对16例HA义眼座植入术后眼座内陷及下移、结膜囊缩窄患者行HA人工骨植入及唇黏膜移植结膜囊成形术，观察术后义眼座内陷和（或）下移矫正、上睑沟凹陷矫正、结膜囊成形情况，义眼座有无外露、感染及HA人工骨有无移位。结果移植唇黏膜全部成活，眼座内陷、移位及上睑沟凹陷基本矫正，眼座无外露，人工骨无移位，患者基本满意。结论羟基磷灰石复合人_T骨片植入联合唇黏膜移植结膜囊成形术是治疗HA义眼座植入术后眼座内陷及下移、结膜囊缩窄的理想方法。

Objective To observe the therapeutic effect and the surgical methods of implantation of Hydroxypatite piece combined with transplantation of lip mucous in conjunctival reconstruction. Methods Sixteen patients （16 eyes） suffered from conjuctival sac stenosis and sunk socket were treated with implantation of Hydroxypatite piece combined with transplantation of lip mucous in conjunctival reconstruction. We observed the rectified sunk socket, the shaping of conjunetival sac, the motion of prosthetic eyes and the implants exposure or infection. Results The sunk socket of all eyes was corrected obviously and the conjunctival sac was shaped well. No implants exposed or infected. Conclusions Implantation of Hydroxypatite piece combined with transplantation of lip mucous in conjunctival is an ideal method to treat sunk socket with narrow conjunctival sac.
