The purpose of this study was to evaluate hard palate asymmetry during development. The palates of 248 dry skulls were photographed and evaluated digitally. The skulls were divided into seven groups: fetus, newborn, infant, child, adolescent, adult, and aged. Linear measures were obtained from great palatine foramen (GPF) to incisive fossa (INC) and to posterior nasal spine (PNS). Angular measures were obtained from the former landmarks plus the point on sutures intersection between maxillary and palatine bones. Asymmetry was evaluated intra and intergroups. All skulls showed some degree of right-left asymmetry in the hard palate. Regardless of hard palate asymmetry, none of the right-left side differences was statistically significant. For the intergroups assessment, none of the asymmetry index means were statistically different. The posterior part of palate (PNS x GPF) measures was more asymmetric than the anterior part (INC x GPF), showing, respectively, 4.6% and 2.8% of mean asymmetry index. Angular measures showed a more symmetric behavior than the linear ones. Hard palate asymmetry occurs even in the absence of masticatory function, showing that this feature begins early in fetal life and persists through development.
