PARANAIBA, Lívia Máris Ribeiro et al. Cleft lip and palate: series of unusual clinical cases. Braz. j. otorhinolaryngol. (Impr.) [online]. 2010, vol.76, n.5, pp. 649-653. ISSN 1808-8694. http://dx.doi.org/10.1590/S1808-86942010000500019.
Cleft lip and/or palate (CL/P) represent the most common congenital anomalies of the face, corresponding to approximately 65% of all malformations of the craniofacial region. AIM: to describe unusual clinical cases of non-syndromic CL/P (CL/PNS), diagnosed in a reference service in Minas Gerais, Brazil, and correlate these alterations with possible risk factors. MATERIALS AND METHODS: we carried out a retrospective study, between the years of 1992 and the 1st half of 2009, from medical records. RESULTS: Among the 778 cases of CL/PNS diagnosed in the period of 17 years, 5 (0.64%) were unusual CL/PNS, and all patients were male. It was found that among the 5 patients, 2 had incomplete right cleft lip with incomplete cleft palate, 2 were affected by left incomplete cleft lip and incomplete cleft palate, and 1 had a cleft lip and palate associated with complete right cleft palate. Risk factors such as consanguinity, maternal smoking and alcohol consumption, medication usage during pregnancy, history of abortion and/or stillbirths and maternal diseases were not associated with unusual CL/PNS. CONCLUSIONS: This study described 5 unusual cases of CL/PNS in a Brazilian population; no associations with the risk factors analyzed were seen. It also confirmed the unusualness of the prevalence of such alterations.
