ABSTRACT Background: Because of the close relationship between pharynx and the dentofacial structures, this study was conducted to find whether the pharyngeal sagittal dimension could be affected by the positional relationships between jaws, and to determine the pharyngeal parameters difference in both genders in different skeletal patterns. Subjects and method: The study sample consists of 120 digital radiographs of Iraqi subjects (60 males and 60 females) attending Orthodontic Clinic in the College of Dentistry; University of Baghdad. The 120 radiographs were divided into three groups (40 radiographs for each group) according to the ANB angles: ANB angle smaller than one degree (Class III), between two and four degrees (Class I), and larger than four degrees (Class II), each group was further divided into two subgroups according to gender (20 radiographs for each gender), eleven linear and two area measurements were used to assess the pharyngeal structures. Results: Student's t-test showed a significant difference (P
