[Modified evisceration for biocolonizable orbital implant: the four-square technique].
BACKGROUND
The introduction of a porous, biocolonizable, orbital implant is difficult after a classic evisceration. We have developed a modification of the method that provides better results.


METHODS
Four scleral squares pediculized on the right oculomotor muscles were cut. They were sutured two-by-two over the anterior part of the implant.


RESULTS
Fifteen patients were operated. There were no complications during a mean follow-up of 12.4 months.


CONCLUSIONS
The soft anterior tissues were protected by the two vascularized scleral layers. The diameter of the implant was 18 mm for three patients, 20 mm for eight patients, and 22 mm for four patients. Operating time was much shorter than with enucleation and covering of the implant with autologous sclera.


CONCLUSIONS
Evisceration with the four-square technique is a safe and quick method, which can be used for most patients, except those with an intraocular neoplasia.
