Frontal and lateral cephalometry in patients with sleep-disordered breathing.

摘要: Objectives/Hypothesis The traditional lateral-view cephalometric analysis is limited because it provides only two-dimensional of the three-dimensional craniofacial structure. objectives were to analyze lateral and frontal radiographs in a series normal patients those with varying degrees sleep-disordered breathing define narrowing or other unfavorable anatomical changes that might differentiate from subjects. Study Design A prospective study 100 adult 60 age-matched subjects. Methods An measurements was performed assess velopharyngeal features. comparison made between patients' polysomnographic analyses. Results compromised parameters may be found include acute skull-base bony nasopharynx angles, inferior hyoid position, thickening velum, reduced retrovelar posterior air space along pharyngeal wall, lumen. Worsening generally associated increased numbers parameters. As body mass index increases, there width, velum thickness increased, wall increased. Conclusions Sleep-disordered statistically significant number measurements. Frontal adds further information regarding assessment upper airway obstruction, enhancing view.
