Background: Canthopexies can be performed to modify the eye slant, both when the lateral canthus is lower than the medial one (congenital defect) or in case the patient asks for an almond-shaped eye (cosmetic indication).Objectives: This peculiar type of canthopexy can be defined as "dynamic canthopexy," meaning that the lateral canthus is released from its original insertion and raised to a higher position. The goal of this study is to demonstrate the differences and the efficacy of the dynamic cantoplasty.Methods: The authors reviewed 30 patients treated with a "dynamic canthopexy" between January 2005 and March 2015. Eighteen patients were affected by true downslanting palpebral fissure, and 12 patients had a normal eye shape but were wishing for a more "Asian" look. Dynamic canthopexy involves a total modification of the canthal suspension system and its careful reconstruction at a higher level inside the orbital rim. To obtain a permanent result, canthal ligament and tendon had to be anchored to drill holes in the orbital rim bone with nonabsorbable sutures. Symmetry was very carefully assessed. The average surgical time was 1 hour.Results: This surgery proved extremely effective in all cases. Patients must be warned, though, that an initial hypercorrection is necessary to achieve the desired canthal position. About 6 months after surgery the result of this operation can be considered permanent. Severe complications are rare.Conclusions: Dynamic canthopexy can provide stable correction of anti-Mongolian slant. It can also be effectively employed to obtain permanent slant eyes when required by purely cosmetic patients. If precisely carried out, this technique can yield very rewarding outcomes.
