ABSTRACT
INTRODUCTION:
Implant exposure is the most frequent complication after evisceration or enucleation, and multiple surgical techniques for the management of orbital implant exposure. The goal of our study is to investigate the success rate and risk factors for failure of various surgical procedures.METHODS:
This was a retrospective study performed at the University Hospital of Limoges. We collected data from the files of every patient operated on for implant exposure between January 2005 and December 2020. The main criterion was the percentage of success for each procedure. Secondary objectives were to identify risk factors for failure of Müller's muscle flaps and to determine the incidence of post-enucleation socket syndrome depending on whether the orbital implant was maintained.RESULTS:
Fifty-one patients were included 26 patients who underwent Müller's muscle flap, 16 dermis-fat graft, 3 conjunctival flap, 2 amniotic membrane graft, 1 temporalis fascia graft, 1 buccal mucosa graft, 1 implant rotation, and 1 implant exchange. The dermis-fat grafts were more successful (87.5%) than the Müller's muscle flaps (52.2%) (P=0.0213). The study highlighted the importance of good vascularization of the implant (OR=32.00, P-value=0.0245) for the success of Müller's muscle flaps, and we found no statistically significant difference between the patients who maintained their implants and those who did not (P=0.3865) with regard to the incidence of post-enucleation socket syndrome.CONCLUSION:
Müller's muscle flap may remain a reasonable option in the management of medium-sized implant exposures of well-vascularized implants confirmed on MRI in patients with no systemic healing disorders. Dermis-fat graft remains the option of choice in other cases, especially in large exposures or complicated orbits.Palavras-chave
