타이타늄 운동축을 삽입한 하이드록시아파타이트 안와삽입물의 합병증에 관한 임상 연구

Clinical Study of the Complications in Titanium Motility Pegged Hydroxyapatite Orbital Implant

Purpose: To evaluate the complications of titanium motility pegged hydroxyapatite orbital implant. Methods: We retrospectively reviewed the records of 77 patients who underwent drilling with titanium motility peg hydroxyapatite orbital implant from May 2000 to April 2005. Results: Of 77 patients (77eyes), 22 complications in 14 eyes (18.2%) occurred: 8 cases of major discharge (10.4%), 7 cases of granulation tissue overgrowth (9.1%), 3 cases of sleeve head exposure (3.9%), 4 cases of peg extrusion (5.2%) and 2 cases of hydroxyapatite exposure around pegged hole (2.6%). Conclusions: Hydroxyapatite exposure around pegged hole was most infrequent among complications of titanium motility peg system. It is considered that the use of titanium motility pegs will increase, as a bioinert material.
