Purpose: We used the Lactosorb® Office fixation kit for correction of post–traumatic medial canthal dystopia to provide secure bony fixation with minimal complications. Methods: Two patients presented with downward shift of medial canthus as a result of scarring following trauma. A dacryocystorhinostomy (DCR) type incision was used to expose the medial canthal tendon. Scar tissue was released with dissection. Lactosorb® screw with pre–placed suture was drilled into the medial orbital wall to anchor the medial canthal tendon. The screw was placed so as to pull the medial canthus medially and posteriorly to give the canthus an appropriate depth. Results: Our technique achieved a satisfactory medial canthal position in both cases, which would have been difficult to achieve otherwise in these challenging cases with extensive scarring. Over a period of 12 months follow–up, there were no complications related to the technique or the devices used. Conclusions: The Lactosorb® fixation kit developed for brow lifts, is a suitable device to correct post–traumatic displacements of medial canthus. It is a simple technique and avoids many of the complications associated with the other techniques. The material has been used in over 7500 craniomaxillofacial procedures and has been shown to be well tolerated.
