Abstract
Objectives: The aim of present study was toassess the vermillion symmetry and scar quality in surgical management of patients with unilateral cleft lip using orbicularis oris muscle z-plasty modified Millard{u2019}s technique versus Fisher{u2019}s technique. Patients and Methods: Twenty patients were selected with primary non-syndromic unilateral cleft lip.The patients were randomly assigned in to two equal groupseach of which ten patients. In group I, eachpatient received unilateral cleft lip repair using orbicularis oris muscle (OOM)z-plasty modified Millard{u2019}s technique. While ingroup II, each patient received unilateral cleft lip repair using Fisher{u2019}s technique.In both groups the Vermillion symmetry of repaired cleft side was evaluated and measured in comparison to the non-cleft side of the same patient by Computerized Photogrammetric Lip Analysis using ImageJ software version 1.50f. For scar evaluation,objective assessment was performed in which the measurements for length and width were obtained by the same manner of analysis as in vermillion. In addition to scar evaluation usingVancouver scar scale at 6 months. Results: The results showed that, the evaluation of vermillion symmetry and scar quality was statisticallyinsignificant during the different follow-up periods (1 week, 3 months and 6 months) between OOM z-plasty modified Millard{u2019}s technique and Fisher{u2019}s technique. Similarly, there was no significant difference in scar evaluation using Vancouver Scar Scale between the two groups. Conclusion:Orbicularis oris muscle z-plasty modified Millard{u2019}s technique used in surgical treatment of unilateral cleft lip is a reliable technique as well as Fisher technique.Whileboth groups showed criteria of success,a very small difference in vermillion notching was documented favoring the OOM z-plasty modified Millard{u2019}s technique
