In this study the relationship between facial directional asymmetry and extreme handedness was investigated in 72 (35 left-handed and 37 right-handed) Turkish males and 76 (39 left-handed and 37 right-handed) females, a total of 148 university students. Asymmetry was determined on the digital photographs of the participants, taken from the front. Handedness was assessed via the Edinburgh Handedness Inventory. Subjects with scores of +100 were designated as extreme right-handers, and participants with scores of -100 were designed as extreme left-handers. The results of the study indicate that in right-handed individuals linear dimensions from the left side were greater when compared with those taken from the right side. In left-handed subjects right dimensions were greater when compared with the left side. However, the difference between the sides was more prominent in right-handed individuals. While significant difference was observed between right and left-handed individuals related with composite directional asymmetry no significant difference was observed between the two sexes. In conclusion, extreme handedness may affect the level of directional facial asymmetry, and this may be caused by the asymmetrical development of the cerebral hemispheres.
