AIM: To observe the clinical effect of prosthodontics membrane and lip mucosa transplantation combined with hydroxy apatite(HA)orbital implantation in the treatment of severe stenosis of conjunctival sac.

METHODS: Nineteen patients with orbital socket and severe stenosis of conjunctival sac were treated with prosthodontics membrane and lip mucosa transplantation combined with HA orbital implantation in reconstruction of conjunctival sac, Survival condition of lip mucosa, HA stability and conjunctival sac depth, palpebral fissure highness and facial appearance were observed after transplantation.

RESULTS: After 3-6 months of follow-up, lip mucosal membrane grew up well and fused with eyeball conjunctiva in all patients. Depth of conjunctival sac was normal and binocular palpebral fissure elevated basically symmetry and satisfactory appearance in 18 patients. One patient was not satisfied with the improved appearance.

CONCLUSION:The method of prosthodontics membrane and lip mucosa transplantation combined with HA orbital implantation is effective and safety in conjunctival sac reconstriction, and also satisfy patients' esthetic need.
