Comparison of Ricketts analysis and Downs-Northwestern analysis for the evaluation of obstructive sleep apnea cephalograms.

To determine which analysis is suitable to examine the dentofacial skeletal pattern characteristics of the obstructive sleep apnea syndrome (OSAS), we took lateral cephalograms of 44 Japanese OSAS patients and 34 Japanese non-OSAS controls. By Ricketts analysis, we found significant differences between OSAS patients and non-OSAS controls on facial axis, lower facial height and total facial height, which showed that Japanese OSAS patients have dolico facial patterns. However, by Downs-Northwestern analysis, we did not find any significant difference between OSAS patients and non-OSAS controls using the same cephalograms as the Ricketts analysis.

Facial patterns of obstructive sleep apnea patients using Ricketts' method.

To analyze the facial patterns of obstructive sleep apnea syndrome (OSAS) patients, we took lateral cephalograms of 31 OSAS patients and 26 non-OSAS controls and utilized Ricketts' method. In addition, we measured the hyoid bone position, the length of mandibular plane to H-point, the length of soft palate, and lower pharynx. The facial patterns of OSAS patients were dolico, the hyoid bone was positioned low, the soft palate was longer and the width of the airway was narrower than that of the non-OSAS controls.
