Ptosis incidence in Porous Versus Nonporous Orbital Implants After Enucleation

Sara Abd El Meged Nage

Background: Enucleation is a surgical procedure that involves the removal of the eye and anterior optic nerve, usually with the extraocular muscles retained and sewn to the implant. To avoid long-term complications and ensure optimal long-term function and cosmesis of an ophthalmic socket, meticulous surgical technique is required.

Objective: To evaluate the ptosis incidence in porous versus nonporous orbital implants after enucleation.

Materials and methods: In this study, 50 patients had primary enucleation with orbital implant placement. Patients were recruited from the Menoufia University Hospital's ophthalmology outpatient clinic between August 2017 and August 2019. Patients were divided into two groups, after enucleation hydroxyapatite orbital implant was used (Group I) and acrylic orbital implant was used (Group II). Full history taking and examination, and ptosis incidence were studied.

Results: Post-traumatic was the most frequent, presented by 17 nonporous patients (68%), and 15 porous patients (60%), followed by tumor by 8 nonporous patients (32%) and 10 porous patients (40%), with non-significant difference (p=0.347). While, all of the studied patients hadn’t vision. Ptosis incidence 1^st month and post-operative did not show any significant difference among non-porous and porous studied groups. Except 2^nd and 4^th months was significantly differed among porous and nonporous groups (p<0.05).

Conclusion: Ptosis occurred in a significantly greater proportion of patients who received a nonporous implant than in those who received a porous implant. Implant exposure occurred at a low rate.
