Pre-Hispanic Evidence of Cleft Lip and/or Palate in Mesoamerica.

In this letter, the authors present archeological evidence of the presence of cleft lip and/or palate (CLP) in pre-Hispanic Mesoamerica. During years 2016 and 2017, the authors visited 5 anthropology museums in Mexico, Guatemala, and El Salvador, in search for pre-Hispanic archeological evidence of CLP, and 16 anthropomorphic figurines with evidence of CLP were identified; 9 at the Anahuacalli Museum, 6 at the National Anthropology Museum of Mexico, and 1 at the National Anthropology Museum of El Salvador. Fifteen of these ceramics originated from the shaft tombs (pre-Hispanic culture from western Mexico, Jalisco, Colima, and Nayarit; dating from 200 bc-600 ad), and 1 ceramic originated from the Cotzumalguapa (a pre-Hispanic culture from western El Salvador dating from 200 ad-900 ad).
