Journal ArticleDOI
Evaluation of swallowing using 320-detector-row multislice CT. Part II: kinematic analysis of laryngeal closure during normal swallowing.
Yoko Inamoto,Naoko Fujii,Eiichi Saitoh,Mikoto Baba,Sumiko Okada,Kazuhiro Katada,Yasunori Ozeki,Daisuke Kanamori,Jeffrey B. Palmer +8 more
TL;DR: Results indicated that the onset of hyoid elevation and the early opening of the PES occurring before three levels of laryngeal closure are critical components for airway protection.
Journal ArticleDOI
The Effect of Bolus Viscosity on Laryngeal Closure in Swallowing: Kinematic Analysis Using 320-Row Area Detector CT
Yoko Inamoto,Eiichi Saitoh,Sumiko Okada,Hitoshi Kagaya,Seiko Shibata,Kikuo Ota,Mikoto Baba,Naoko Fujii,Kazuhiro Katada,Pattra Wattanapan,Jeffrey B. Palmer +10 more
TL;DR: The results suggest that bolus viscosity alters the temporal characteristics of swallowing, especially closure of the TVC.
Journal ArticleDOI
Anatomy of the larynx and pharynx: effects of age, gender and height revealed by multidetector computed tomography
Yoko Inamoto,Yoko Inamoto,Eiichi Saitoh,Sumiko Okada,Hitoshi Kagaya,Seiko Shibata,Mikoto Baba,Keiko Onogi,Shuji Hashimoto,Kazuhiro Katada,P. Wattanapan,Jeffrey B. Palmer +11 more
TL;DR: It is suggested that age, gender and height have independent and interacting effects on the morphology of the pharynx and larynx.
Journal ArticleDOI
Evaluation of Swallowing Using 320-Detector-Row Multislice CT. Part I: Single- and Multiphase Volume Scanning for Three-dimensional Morphological and Kinematic Analysis
Naoko Fujii,Yoko Inamoto,Eiichi Saitoh,Mikoto Baba,Sumiko Okada,Satoshi Yoshioka,Toshiaki Nakai,Yoshihiro Ida,Kazuhiro Katada,Jeffrey B. Palmer +9 more
TL;DR: A reclining chair that allows scanning to be performed with the subject in a semisitting position, which makes swallowing evaluation by 320-MSCT applicable not only to research on healthy swallowing but also to the clinical examination of dysphagia patients.
Journal ArticleDOI
The risk of penetration or aspiration during videofluoroscopic examination of swallowing varies depending on food types.
Kenichiro Ozaki,Kenichiro Ozaki,Hitoshi Kagaya,Michio Yokoyama,Eiichi Saitoh,Sumiko Okada,Marlís González-Fernández,Jeffrey B. Palmer,And Hiroshi Uematsu +8 more
TL;DR: Risk of laryngeal penetration or aspiration during VF is highest with the two-phase food, and multi-textured foods should be used with caution in individuals with dysphagia.
