Abstract

During primary cleft lip repair, a small triangular flap of about 2 mm is sometimes required to achieve better symmetry of Cupid's bow. The aim of this study was to evaluate the symmetry of Cupid's bow, with and without the use of a small triangular skin flap (STSF). Forty-five children who underwent the repair of unilateral cleft lip between January 1999 and December 2000 were recruited. Twenty children had a STSF included in the repair (STSF group) an d 25 children underwent the same repair without the STSF (NSTSF group). Vermillion height was measured on the cleft and non-cleft sides using reference points. The t-test was used to compare the vermillion height ratio between the two groups. The mean age at surgery was 4 ± 1.3 months in the STSF group and 4.3 ± 0.6 years in the NSTSF group. There was no significant difference in vermillion height ratio at 5 years of age between the patients in the two groups. Thus, there is no difference in vermillion height ratio with or without a STSF in cleft lip repair. The use of a small triangular skin flap needs to be assessed carefully, as it will create an unsightly scar over the philtrum area.
