Lip-palatine fissures are congenital craniofacial malformations caused by embryological defects. They occur between the 4th and 12th week of gestation, with the 6th being the highest risk.
The etiologies are divided between environmental factors such as: maternal age, antiepileptic drugs, smoking, alcohol consumption during pregnancy, obesity, diabetes, lack of folic acid in diet and genetic factors. This pathology can be part of a recognizable pattern of a malformation syndrome; however, it also occurs as an isolated event. Therefore, for itsdiagnosis other specialized studies are required.
The treatment is surgical and they include, cheilorrhaphy, that has an aesthetic purpose, and palatoplasty, whose effect is functional as it repairs the velopharyngeal sphincter and the roof of the oral cavity.
We present a case with incomplete unilateral cheiloschisis and type II palatoschisis.
