A technique for medial canthal fixation using resorbable poly-L-lactic acid-polyglycolic acid fixation kit.

Achieving secure bony fixation of medial canthus is a challenge. We used a resorbable poly-L-lactic acid-polyglycolic acid screw (LactoSorb office fixation kit) in 5 cases: 2 with traumatic medial canthal dystopia, 1 with scleroderma and orbital fat atrophy causing malapposition of the medial canthus to globe, and 2 with invasive medial canthal tumors necessitating subtotal medial orbital exenteration. The resorbable screw with preplaced suture was drilled into the medial orbital wall, using a handheld self-drilling tap. The preplaced suture was used to anchor the medial canthus. We achieved satisfactory canthal position in all 5 cases. There were no complications in 4 cases during a mean +/- SD follow-up of 11.3 +/- 6 months; however, the scleroderma case developed wound dehiscence 6 weeks after surgery. The LactoSorb kit is a safe and effective technique to achieve bony medial canthal fixation in carefully selected cases.
