ABSTRACT
AIM: To compare the clinical effects of the modified and conventional secondary hydroxyapatite orbital implantations.METHODS:A total of 40 patients who had received eye enucleation were equally randomized into the modified and conventional groups. Twenty patients were treated by conventional method. The four rectus muscles were separated, and then an orbital implant wrapped with xenogenous sclera was implanted. Twenty patients were treated by modified method. An implant unwrapped with xenogenous sclera was directly implanted into the muscle pyramid. The operating time, costs, clinical effects, and complications of the two groups were compared.RESULTS:The average operating time of the modified group was 20.5±5.6min, whereas that of the conventional group was 56.8±14.6min (P
