title: [Incidence of cleft lip and palate in the General Hospital Dr. Aurelio Valdivieso of Oaxaca, México, between 2008 and 2010].
abstract: BACKGROUND
  Cleft lip and/or palate (CL/P) is the most common craniofacial anomaly.
  
  
  OBJECTIVE
  to determine the incidence of cleft lip and/or palate (CL/P) in patients born in the Hospital "Dr. Aurelio Valdivieso" in the city of Oaxaca between 2008 and 2010.
  
  
  METHODS
  A retrospective, cross-sectional study on all live births with non-syndromic orofacial cleft was realized. The variables included were CL/P presence, sex, and birth year. Clinical records of CL/P subjects were reviewed and clefts classified according to Kernahan and Stark. Tables were generated to present data.
  
  
  RESULTS
  The total number of live births (LB) was 24,043 for the 2008 to 2010 period. In 2008, 9 cases (rate 1.01 per 1,000 LB) were identified: 7 boys and 2 girls. In 2009, there were 4 cases (rate 0.54 per 1,000 LB), 3 boys and 1 girl. In 2010, there were 11 cases (rate 1.42 per 1,000 LB), 7 boys and 4 girls. The total for the period 2008-2010 were 24 cases (rate 1.00 per 1,000 LB), 17 boys and 7 girls. Incidence rate was higher among male than among female. As for the distribution according to Kernahan and Stark classification, there were 4 boys and 3 girls in group "C", 10 boys and 4 girls in group "D", and only 3 boys in group "E"; not a single case in groups "A" and "B".
  
  
  CONCLUSIONS
  The incidence for the period was 1.00 per 1,000 LB. The CL/P was more frequent in boys for each year included in the study.
