Fulltext PDFIn the Background, characteristics of homo sapiens were described. The structural weak point is the neck. Homo sapiens are born with the tongue and the epiglottis and larynx deviated upward and forward. The state of that was exactly ankyloglossia with deviation of the epiglottis and larynx (ADEL). ADEL inhibits respiration. For correction of ADEL, both correction of the glosso-larynx (CGL) and the expansion of the vestibular oris (EVO) were done. In this study total of 334 cases with complaints of sleep disorders were studied. Nasal patency and changes in sleep were measured by acoustic rhinometry and by questionnaires before and one month after CGL and EVO. Average patency of the nasal valve area before and one month after were 1.3 cm2 and 1.4 cm2, respectively, and of the piriform area were 1.7 cm2 and 2.9 cm2, respectively. Nasal volume for these time periods was 17.6 cm3 and 19.8 cm3, respectively. The volume and area of the nasal cavity was augmented. Questionnaires showed much amelioration of sleep after CGL and EVO, indicating that the increase in nasal patency resulted in good sleep. Results indicated that one role of the nose is cooling of the brain. The facial cranium consists a heat exchange system for the brain.
