Abnormal union of the facial processes during intrauterine life results numerous anomalies, among the most common are orofacial clefts. In 1976 the doctor Tessier, conducted a classification for each of these malformations where macrostomia or lateral facial cleft, transverse facial cleft palate or type 7 Tessier is included as an unusual congenital anomaly character. Clinically asymmetry of the labial commissure affecting the tissues around the mouth are observed. In severe cases the crack exceeds the anterior border of the masseter muscle extending from the labial commissure to the pinna, in some cases the ramus, the condyle and the zygomatic arch may be absent, with or without absence of the parotid gland. The macrostomy can be a non syndromic or syndromic anomaly, in the latter case is associated with hemifacial microsomia, Treacher-Collins syndrome, Goldenhar syndrome, Ablepharon Syndrome -macrostomia, Barber-Say syndrome, etc.. Therapeutic actions are mostly surgical such as labiaplasty or comisuroplastías. The Z plasty and W plasty are the most used for the surgical treatment of this type of cracking techniques.
