[Enucleation with on-the-table evisceration. Is it a good technique?].

PURPOSE

To evaluate the surgical technique of enucleation followed by an "on-the-table evisceration" and placement of a hydroxyapatite orbital implant wrapped by the patient's own sclera for the treatment of blind phthisis painful eyes.

PATIENTS AND METHODS

In this single-center retrospective study, 50 consecutive patients undergoing an operation using the same surgical technique, between April 1993 and November 1999, were studied. Patients underwent enucleation, then the eyeball was eviscerated "on the table". The patient's own cleaned sclera was used to wrap a hydroxyapatite orbital implant, the posterior pole of the sclera was placed at the anterior pole of the implant. Conjunctival breakdown, sphere size, conjunctival discharge, the first signs of sympathetic ophthalmia motility, and cosmetic results were analysed.

RESULTS

After an average follow-up of 13.3 months few complications were encountered: 4 cases (8%) of inclusion cyst and 3 cases (6%) of discharge. The implant placed had a diameter of 18 mm, 20 mm, 22 mm in, respectively, 48%, 48%, and 4% of the eyes. The prosthesis motility was good, medium, and poor in, respectively, 33 (78.6%) cases, 8 (19%) cases, and 1 (2.4%) case. The prosthesis tolerance was good, medium, and poor in respectively 86%, 10%, and 4% of the cases.

CONCLUSION

The surgical technique of enucleation followed by an "on-the-table" evisceration and autologous sclera wrapping a hydroxyapatite implant is an easy procedure. It allows, on phthisis eyeballs, the placement of a large orbital implant for good cosmesis results, without major complications.
