Many surgical procedures for macrostomia had been advocated in past literatures, but it is hard to obtain the ideal commissure form. In this paper, 6 cases of unilateral macrostomia treated at our clinic are reported and the availability of the minor triangular flap on vermillion border in commissuroplasty is discussed.
Five cases underwent new commissuroplasty using the minor triangular flap at vermillion border (Matsuya's procedure) and 1 case without it. In the latter case, deformation of the commissure form caused by postoperative scar contracture was found, though the good form was found during the post-operative period. In all cases using Matsuya's procedure, the good commissure form was made and maintained throughout the growth period. The minor triangular flap on vermillion border was considered to be useful to prevent the influence of postoperative scar contracture on the commissure form
