The purpose of the present study was to investigate whether or not sensory input from the tongue affects deglutitive tongue movement. Subjects were seven healthy volunteers with anesthetic applied to the surface of the tongue (surface group) and seven healthy volunteers with the lingual nerve blocked by anesthetic (blocked group). We established six stages in deglutition and analyzed deglutitiv...

Pronunciation training based on speech production techniques illustrating tongue movements is gaining popularity. However, there is not sufficient evidence that learners can imitate some tongue animation. In this paper, we investigated human awareness of controlling their tongue body gestures. In a first experiment, participants were asked to perform some tongue movements. This task was evaluat...

A new three-dimensional tongue model has been developed within the KTH 3D vocal tract project using manually extracted tongue contours from MR Images of a reference subject producing 43 artificially sustained Swedish articulations. The six linear parameters jaw height, tongue body, tongue dorsum, tongue tip, tongue advance and tongue width were determined using an ordered linear factor analysis...

BACKGROUND Multilevel obstruction in obstructive sleep apnea commonly includes retroglossal obstruction. To improve surgical success rates, tongue volume reduction with posterior midline glossectomy and/or lingual tonsillectomy is widely performed. METHODS Nasotracheal intubation was utilized, and the combined tongue procedure was performed as a final step after palatal surgery. The tongue wa...

introduction: among different kinds of oral cavity cancers, the frequency of tongue cancer occurrence is more significant. brachytherapy is the most common method to cure tongue cancers. long sources are used in different techniques of tongue brachytherapy. the objective of this study is to asses the dose distribution around long sources, comparing different radioisotopes as brachytherapy sourc...

The tongue enables taste and plays a critical role in formation of food bolus and deglutition. The tongue is also crucial for speech and the earliest sign of tongue paresis is a change in the quality of speech. Given the importance of the tongue, tongue carcinoma should be accurately staged in order to optimise treatment options and preserve organ function. The intent of this review is to famil...

The projectile tongue of caudate amphibians has been studied from many perspectives, yet a quantitative kinetic model of tongue function has not yet been presented for generalized (nonplethodontid) terrestrial salamanders. The purposes of this paper are to describe quantitatively the kinematics of the feeding mechanism and to present a kinetic model for the function of the tongue in the ambysto...

The purpose of this study was to use cineradiographic images to investigate tongue movement during deglutition in anterior open bite patients with tongue thrust. Each subject had semi-spherical lead markers attached to the tip and dorsal surface of the tongue and was asked to swallow 5 ml of diluted liquid barium. Tongue movement during deglutition was recorded in the mid-sagittal plane with an...

OBJECTIVE To research the mechanism of the tongue inspection in traditional Chinese medicine and to study the special relationship between temperature distribution of the tongue and the tongue color. METHODS The temperature field of human and pig's tongue was measured by infrared thermal vision system and thermal-couple probe. The blood perfusion rates in the human tongue and the pig's tongue...
