ABSTRACT
Purpose: To evaluate four petals evisceration as one of the best modifications in evisceration surgery, allowing the use of large orbital implant with low incidence of complications
Methods: We conducted a retrospective, interventional study on evisceration with placement of spherical non porous orbital implant after four petal evisceration. Preoperative examination included full history, ophthalmological examination, indication for surgery, B-scan ultrasonography, axial length in cases of atrophic and socket surface in secondary cases. All patients were operated a four petal evisceration with spherical non porous implant of size 18 to 22. Postoperative, all patients were followed for at least 6 months for presence of complications, implant and prosthesis motility and the final cosmetic results
Results: 18 eyes were included. Diagnosis necessitating evisceration was atrophia bulbi in 8 patients, endophthalmitis in 2 patients, and implant exposure in 4 patients, corneoscleral melting due to caustic exposure in 1 patient, self-eviscerated globe due to severe trauma in 1 patient and anopthalmic socket following evisceration without implant in 2 patients. Implant size was 18 in 1 patient, 20 in 6 patients, and 22 in 11 patients. No implant exposure occurred; superior sulcus deformity occurred in 3 patients, downward implant migration occurred in 1 patient. Regarding implant motility, it was good with mean of 75% in 14 patients; moderate with mean of 66% in 4 patients. The prosthesis motility was fair with mean of 35% in 12 patients [66.6%] and poor with mean [10%] in 6 patients
Conclusion: Four petals evisceration facilitates the use of large sized implant in all cases even in implant exposure with deficient sclera with good post-operative final cosmetic results, very low rate of complications and moderate prosthesis motility
