Abstract

The relationship between intraorbital hydroxyapatite implantation and drilling was studied in 85 cases of 85 patients from September 1991 through December 1996 in the Separtment of Ophthalmology, Yeungnam University College of Medicine. The incidence of drilling after intraorbital implantation and the causes of not being able to drill were evaluated. Postoperative extraocular muscle and prosthetic motility of the cases with and without drilling were reviewed. Drilling was performed in 39 cases(45.9%). Forty-six cases were not received drilling due to mildly contracted, tight socket(17 cases), satisfactory prosthetic motility without drilling (13 cases), limitation of extraocular muscle motility(9 cases), thin prosthesis(4 cases) and exposure of implant(3 cases). A fter the follow-up period of 6-56 months(mean 18 months), postoperative prosthetic motility was satisfactory in 30 cases(76.9%) in drilling cases and 12 cases(26.1%) in non-drilling cases.
