[Primary orbital implant dislocation. A retrospective study].
BACKGROUND
To compensate the orbital volume deficit after enucleation orbital implants are used.


METHODS
Between 1986 and 1996, 449 enucleations were performed. One hundred and fifty-five orbital implants were used: 96 hydroxylapatite-ceramic-silicon (HAK-silicon), 29 hydroxylapatite-ceramic (HAK), 26 Kiel bone chips, 3 Walser and 1 Bangerter implant.


RESULTS
Ten orbital implants (6.45%) had to be explanted. Seven of the 96 HAK-silicon implants were explanted: four could be changed, two of them with a smaller and two with a same diameter. We observed a complication rate of 7.29% and a rate of total loss of 3.13%. One luxated HAK-implant could be refixated (3.45%), and one implant (3.85%) of the Kiel bone chip implants was explanted.


CONCLUSIONS
Using different types of orbital implants after enucleation, we observed a complication rate of 7%. However, to avoid the post-enucleation-syndrome and to achieve better motility of the prosthesis, orbital implants should be used.
