Use of real-time MRI in assessment of consonant articulation before and after tongue surgery and tongue reconstruction
نویسندگان
چکیده
The present paper describes first results on impaired articulation after partial glossectomy and oral reconstruction. The tongue movements are recorded by dynamic MRI (8 images per second) while the patients utter test words involving all lingual consonants of German. Along 13 lines of a semicircular grid, the tongue–palate distance is measured for all consonants, and preand postoperative movements are compared. To supplement the MR recordings, the speech is recorded acoustically. Eventually, the results will be compared with results from the video fluoroscopy technique, which has already proved to be useful in the evaluation of tongue and velum movements.

Speech and swallowing function after reconstruction with a radial forearm free flap or a pectoralis major flap for tongue cancer.
BACKGROUND AND PURPOSE The tongue plays a more significant role in English than in Mandarin, both in apical-palatal consonant production and tense-lax distinction. Theoretically, the same surgical intervention may produce a less significant impact on postoperative Mandarin production. The impact of tongue reconstruction on Mandarin articulation has not been reported. This study compared the ton...
متن کاملExtracting the Movement of Lip and Tongue During Articulation
A method that extracts the 3-D shape and movement of lip and tongue and displays them simultaneously is presented. Lip movement is easily observable and thus extractable using a camera. However, it is difficult to extract the real movement of tongue exactly because the tongue may be occluded by the lip and teeth. In this paper, we use a magnetic resonance imaging (MRI) device to extract the sag...
متن کاملOpti-speech: a real-time, 3d visual feedback system for speech training
We describe an interactive 3D system to provide talkers with real-time information concerning their tongue and jaw movements during speech. Speech movement is tracked by a magnetometer system (Wave; NDI, Waterloo, Ontario, Canada). A customized interface allows users to view their current tongue position (represented as an avatar consisting of flesh-point markers and a modeled surface) placed i...
متن کاملA Rare Case of Epignathus Combined with Soft Cleft Palate, Bifida Tongue, and Lingual Lipoma
Congenital tumors of the oral cavity are not common.Teratoids are the most common tumors, and in rare cases are associated with cleft soft palate. In this paper a rare case of Epignathus with cleft soft palate, bifida tongue, jaw malocclusion, tongue lipoma, Hypertelorism and low-set ears has been presented. A female infant with a large mass covered with skin and hair arising from hard palate, ...
متن کاملSpeech outcome after surgical treatment for oral and oropharyngeal cancer: a longitudinal assessment of patients reconstructed by a microvascular flap.
BACKGROUND The aim of the study was to analyze speech outcome for patients with advanced oral/oropharyngeal cancer treated with reconstructive surgery and adjuvant radiotherapy. METHODS Speech tests (communicative suitability, intelligibility, articulation, nasality, and consonant errors) were performed in a control group and in patients before treatment (n = 76), and 6 months (n = 51) and 12...
