Abstract:
Objective:In clinical, cephalic index is the most common method to evaluate scaphocephaly. However, cephalic index alone is not sufficient to describe the nuances of skull shape. The authors hypothesize that the location of euryon could be a valuable and practical index as the supplement of cephalic index to better describe the skull.
Methods:This is a retrospective study. CT scans of 17 scaphocephaly patients and 17 normal controls were included. Eight of 17 scaphocephaly patients have 6 months postoperative CT scan. The preoperative location of euryon of scaphocephaly patients was compared to that of the controls and postoperative. The horizontal location of euryon was defined as the ratio of the distance, from the most prominent point of forehead to euryon, to anteroposterior cranial length. The vertical location of euryon was defined as the ratio of the vertical distance, from the nasion to euryon, to cranial height.
Results:Both the horizontal and vertical locations of euryon of preoperative scaphocephaly patients were significantly decreased compared to normals (46.50%±4.02% vs. 50.39%±2.21%, t=3.49, P=0.0014; 35.78%±8.62% vs. 52.6%±8.08%, t=5.86, P<0.001). Both the postoperative horizontal vertical locations of euryon were significantly increased, when compared to preoperative (47.25%±4.23% vs. 44.02%±3.72%, t=2.42, P=0.045; 42.39%±9.06% vs. 35.18%±5.36%, t=2.554, P=0.0379).
Conclusions:The location of euryon could be a practical and valuable index to describe the nuances of skull shape.
