ABSTRACT
Anatomy and facial dimensions are handy to surgeons carrying out repair and reconstruction of facial deformities to maintain optimal relationships among facial structures. The aim of the study was to determine the length to width ratio of adult male and female lips in Oron people of Akwa Ibom State of Nigeria to ascertain what describes a normal lip dimension for the Oron people. Lip size (length and width) was measured in a total number of one thousand (1000) apparently healthy subjects divided into 500 males and 500 females who were randomly selected. The subjects were healthy adults aged between 18 – 45 years without any lip injury or known history of lip surgery. Measurement was taken using a digital Vernier caliper with precision of 0.1mm. Data obtained was subjected to statistical analysis and results were presented in tables. Result showed that mean lip length for the males was 52.26±0.16mm and width 24.06±0.13mm while the lip length for the females was 52.70±0.15mm and width 24.29±0.13mm. Mean lip length to width ratio of the males was 2.20±0.25 and that of the females was 2.20±0.27. Our finding leaves the ratio of length to width measurement of adult male and female lips in Oron at 1:1. Though the mean male value was higher than that of the females, no statistically significant difference was observed. It is therefore not sexual dimorphic. This study could be useful in maxillofacial surgery and anthropological studies.
