  • Effects of mandibular advancement on supine airway size in normal subjects during sleep.
    Sleep, 2003
    Co-Authors: Shigetoshi Hiyama, Satoru Tsuiki, Takashi Ono, Takayuki Kuroda, Kimie Ohyama
    Abstract:

    Study Objectives: To examine changes in the upper-airway dimension and its surrounding structures induced by mandibular advancement during sleep. Design: Eleven nonapneic adult males participated in the study. A set of supine lateral cephalograms was taken for each subject at the end of expiration during stage 1 and 2 non-rapid-eye-movement sleep with and without a Klearway appliance (Great Lakes Orthodontics, NY, USA), which was adjusted to 67% of the maximum protrusion position. The Wilcoxon signed-rank test was used to compare changes in the anteroposterior width of the upper airway and the positions of the hyoid bone and Third Cervical Vertebra with and without the appliance. Setting: N/A Patients or Participants: N/A Interventions: N/A Measurements and Results: The amount of jaw opening was significantly increased by wearing the titratable oral appliance, and the mandibular symphysis moved backward. The sagittal dimension of the superior pharyngeal airway was significantly increased; however, no significant changes were found in the middle and inferior pharyngeal airway. Significant posterior displacement of the hyoid bone and Third Cervical Vertebra was seen. Moreover, significant inferior displacement of the hyoid bone was also seen. The relationship among the mandibular symphysis, the hyoid bone, and the Third Cervical Vertebra remained constant. Conclusions: Mandibular advancement significantly increases the size of the upper airway in the velopharynx and results in posteroinferior displacement of the hyoid bone and posterior displacement of the Third Cervical Vertebra during sleep.

  • Effects of a titratable oral appliance on supine airway size in awake non-apneic individuals
    Sleep, 2001
    Co-Authors: Satoru Tsuiki, Shigetoshi Hiyama, Takashi Ono, Takayuki Kuroda, Naoko Imamura, Yasuo Ishiwata, Alan A. Lowe
    Abstract:

    Study objectives: To define morphological changes in the upper airway and its surrounding structures after the insertion of a titratable mandibular repositioner. Design: Ten non-apneic adult males participated in this study. A set of supine lateral cephalograms was taken for each subject at the end of expiration with a titratable oral appliance in place in four mandibular positions: most retruded (RP), maximum protrusion (MAX), 33% of MAX (MAX 33 ), and 67% of MAX (MAX 67 ). Changes in the anteroposterior width of the upper airway, positions of the hyoid bone and the Third Cervical Vertebra were compared between the four mandibular positions. An ANOVA was used to test for statistical significance. Setting: N/A Patients or Participants: N/A Interventions: N/A Measurements and Results: The anteroposterior width of the velopharynx significantly increased when the mandible was advanced from RP to MAX 67 and MAX. However, there were no significant changes in the anteroposterior width of the oropharynx. Significant forward displacement of the hyoid bone and Third Cervical Vertebra together with the mandible was found in MAX 67 and MAX compared to RP. Conclusion: Especially in MAX 67 and MAX, the titratable oral appliance significantly enlarges upper airway size in the velopharynx and results in a forward displacement of the hyoid bone and the Third Cervical Vertebra.
