FLORES CLEMENTE, Israel  and  NIETO MUNGUIA, Ana María. Functional and aesthetical analysis of primary lip corrective surgery through the rotation and advancement modified technique of unilateral cleft lip. Rev. Odont. Mex [online]. 2011, vol.15, n.3, pp.143-151. ISSN 1870-199X.

The aim of this study was to compile functional and aesthetical results obtained by the closure of unilateral cleft lip utilizing primary rotation and advancement modified technique in 5 patients (3M:2F), during a period of 8 months; these patients underwent surgery at the Regional Hospital Lic. Adolfo Lopez Mateos. Specific anatomical points were considered A, B, C, D. Measurements were monitored and recorded at the following stages : pre-surgical, one immediately after the surgery, and control measurements after one, two and three months. According to the statistical analysis significant changes were observed in relation to the vertical longitude obtained. When taking into account Friedman s Anova analysis it was found that for the longitude d1 = A*-B* there is a range P = 0.00344, with a vertical average response, with a 95% reliability range, d2 = C*-D*, range P: 0:001445, d3 = A-B, range P: 0.0025, d4 = C-D, range P: 0.01785, with a higher approximation to the healthy side longitude during the immediate post-surgical period. However this gained vertical longitude, after a month began to decrease getting further away from the post-surgical line, with a 27% vertical retraction and a 27% relaxation percentage and 48% stability period, bearing aesthetical impact with discreet vertical elevation of the vermillion edge in horizontal relation, simulating a triangle related to the scarring retraction which varies according to the length of the fissure. Along the scarring line reconstruction of the ridge of the affected side can be observed. The ridge can initiate in the central zone of the columella or slightly before, extending in oblique sense (lateral and inferiorly) up to the vermillion edge, forming a discrete concavity in its internal part and as well as convexity in the external part, simulating the absent philtrum crest, simultaneously contributing to the formation of the philtrum groove and bow of Cupid.
