PURPOSES: The study is to describe a new surgical technique for correcting large orbital implant exposure with extraocular muscle flaps and to propose a treatment algorithm for orbital implant exposure.METHODS: In a retrospective study, seven patients with orbital implant exposure were treated with extraocular muscle flaps.All data were collected from patients in Chang Gung Memorial Hospital, Taiwan during 2007-2012.

All surgeries were performed by one surgeon (Y.J.T).

Patient demographics, the original etiology, details dye shampoo of surgical procedures, implant types, and follow-up interval were recorded.Small exposure, defined as exposure area smaller than 3 mm in diameter, was treated conservatively first with topical lubricant and prophylactic antibiotics.Larger defects were managed surgically.

RESULTS: Seven patients consisting of two males and five females were successfully treated for orbital implant exposure with extraocular muscle flaps.The average age was 36.4 (range, 3-55) years old.

Five patients were referred from other hospitals.One eye was enucleated for retinoblastoma.The other six eyes were eviscerated, including one for endophthalmitis and five for trauma.

Mean follow-up time of all seven patients was 19.5 (range, 2-60) months.No patient developed recurrence of exposure during follow-up.

All patients were fitted with an acceptable prosthesis and had satisfactory cosmetic and functional results.CONCLUSIONS: The most common complication of orbital implant is exposure, caused by breakdown of the covering layers, HOW TO QUIT SHAMPOO:THE ORIGINAL CLEANSE leading to extrusion.Several methods were reported to manage the exposed implants.

We report our experience of treating implant exposure with extraocular muscle flaps to establish a well-vascularized environment that supplies both the wrapping material and the overlying ocular surface tissue.We believe it can work as a good strategy to manage or to prevent orbital implant exposure.
