Upper airway enlargement during <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content> therapy is critical, and lateral cephalometry has been used for the two\u2010dimensional evaluation of upper airway form during this therapy. However, this method cannot provide an accurate three\u2010dimensional (3D) view of upper airway form. To confirm the effects of <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content> on the upper airway in patients with <jats:styled-content style=\"fixed-case\">OSAS<\/jats:styled-content>, we performed <jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> in the presence and absence of <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content> in 15 Japanese patients (12 males, 3 females) who responded to <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content> therapy. <jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> in the presence and absence of <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content> was consecutively performed for each patient, and upper airway cross\u2010sectional area in six arbitrary planes parallel to the palatal plane was measured. Next, 3D image reconstruction was performed; morphological changes in upper airway form were evaluated, and upper airway volume at three levels from the palatal plane to the deepest point of the epiglottis was measured. The cross\u2010sectional area of two planes in the posterior soft palate region significantly increased in the presence of <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content> compared with that in the absence of <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content>. In the presence of <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content>, upper airway cross\u2010sectional area and volume significantly increased in the posterior soft palate region compared with those in the posterior tongue region. 3D <jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> image reconstruction accurately confirmed morphological changes in the upper airway during <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content> therapy. Continued use of this 3D evaluation is expected to improve the results of <jats:styled-content style=\"fixed-case\">OA<\/jats:styled-content> therapy in the
