Assessment of the anterior (ASD), posterior (PSD), superior (SSD), and medial space dimensions (MSD). a Sagittal view with Line A drawn through the most superior aspect of the glenoid fossa parallel to the FH plane. The lines tangent to the most prominent anterior (Line B) and posterior (Line C) condylar surfaces were constructed from the most superior surface of the glenoid fossa. ASD and PSD were measured from the most prominent anterior and posterior points of the condyle to the glenoid fossa. SSD was the vertical distance from the most superior aspect of the glenoid fossa to the condyle. b Coronal view with Line A drawn through the most superior aspect of the glenoid fossa perpendicular to the FH plane. The line tangent to the most prominent medial condylar surface (Line B) was constructed from the most superior surface of the glenoid fossa. The MSD was measured from the most prominent medial point of the condyle to the glenoid fossa
