These have been reported to be localized in the interlabial
sulcus, the paramedian area of the perineum and around the anus (5-7).
Inclusion criteria was age 15 to 40 years, class I occlusion with minor or no crowding on clinical assessment, symmetrical face on clinical evaluation, normal overjet and overbite, Competent lips and interlabial
Labia majora is involved most commonly and in descending order labia minora, interlabial
vestibule, clitoris, posterior fourchette and mons pubis are involved.1,2
No significant difference was seen in interlabial
exposure at midline; at the level of the canines there was a 56.4 percent improvement.
Long and average face interlabial
angles (Sn-Ls/Li-Sn) were wider than that of large face (**), with p > 0.01.

Clinical examination showed a congenital bilateral complete palsy of facial nerve and dysfunction of lateral movements in both eyes, convex profile, reduced lower anterior facial height, open nasolabial angle, severe micrognathia, and incompetent lips with interlabial
separation at rest of 13 mm (Figure 1).
Vertically, the lower lip length decreases in the test group; the decreased bone support and overclosure could be the reasons, which can be confirmed by the decrease in the interlabial
gap among the missing teeth group (Table 4), interestingly, upper lip length was decreased as well in group 2, yet this was not significant.
Se ubicaron los puntos cefalometricos y en cada radiografia se determinaron las medidas lineales: plano oclusal (PO) incisivo central maxilar (IS) y mandibular (II), angulo interincisal, grosor labio superior (GLS) e inferior (GLI), angulo nasolabial (ANL), proyeccion de labio superior (PLS) e inferior (PLI), Gap interlabial
y la linea vertical nasion-menton (LVV).
