“…43 The stubbornness of C3-H has been suggested to be ascribed to neuromuscular adaptation to maintain the homeostasis of respiration during sleep. 44. However, the decrease in the activity of the hyoid muscle, 39 which may result from reduced neuromuscular compensation, 45 may lead to shortening of the distance between the hyoid bone and the cervical vertebra during sleep.…”

Abstract:The purpose of this study was to examine sleep-related changes in the upper airway and surrounding structures including the mandible, hyoid bone, and cervical vertebra in normal subjects using lateral cephalograms in the supine position. Eleven male and nine female healthy adults participated in this study. Supine cephalograms were taken at end-expiration during wakefulness and in stage 1-2 non-rapid-eye-movement (NREM) sleep judged from the electroencephalogram and respiratory monitoring. A paired t-test was used to compare differences between the values measured during wakefulness and sleep. A significant increase in the amount of jaw opening was observed during sleep. The anteroposterior width of the upper airway was significantly decreased during sleep. The distances between the hyoid bone and the mandibular symphysis and between the cervical vertebra and the hyoid bone were significantly decreased during sleep. Consequently, the distance between the cervical vertebra and the mandibular symphysis was significantly decreased. These results suggest that the upper-airway dimension is significantly decreased and relatively small structural changes are induced during sleep in normal subjects.

This study compares the topography of the pharyngeal structures of 115 patients with isolated and combined cleft palates with the topography of the pharyngeal structures of 115 patients without cleft palates. The study revealed that the sagittal dimensions in the cleft palate patients are significantly reduced. The maximum closeness can be observed at the lower margin of the velum. In order to clarify growth dependent change of the sagittal pharynx dimensions the growth of the pharynx of 61 cleft palate patients was documented at 4 different points in time between age 7 and age 18. Over this period of growth only a slight increase in the sagittal plane of the pharyngeal area was observed. Especially conspicuous was the stagnation of the distance of the lower margin of the velum to the posterior pharyngeal wall. An increase in air passage resistance, which is the cause of incompetent breathing with all its consequences for growth and dentition development, is derived from these topographical relationships. The study concludes that the postoperative functional competence of the velum is a conditio sine qua non not only in relation to speech but also in relation healthy breathing.
