A three-dimensional model of vocal fold abduction/adduction.
A three-dimensional biomechanical model of tissue deformation was developed to simulate dynamic vocal fold abduction and adduction. The model was made of 1721 nearly incompressible finite elements. The cricoarytenoid joint was modeled as a rocking-sliding motion, similar to two concentric cylinders. The vocal ligament and the thyroarytenoid muscle's fiber characteristics were implemented as a f...
متن کاملVocal Fold Medialization, Arytenoid Adduction, and Reinnervation
127 Restoration of vocal function with laryngeal framework surgery (laryngoplastic phonosurgery) was introduced at the beginning of the 20th century. Today, these procedures have emerged as the dominant surgical management approach for the treatment of the aerodynamic incompetence and acoustic deterioration associated with vocal fold paralysis/paresis. Other indications include cancer defects, ...
متن کاملMonitoring vocal fold abduction through vocal fold contact area.
A number of commercial devices for measuring the transverse electrical conductance of the thyroid cartilage produce waveforms that can be useful for monitoring movements within the larynx during voice production, especially movements that are closely related to the time-variation of the contact between the vocal folds as they vibrate. This paper compares the various approaches that can be used ...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Combined arytenoid adduction and laryngeal reinnervation in the treatment of vocal fold paralysis.
OBJECTIVE/HYPOTHESIS Glottal closure and symmetrical thyroarytenoid stiffness are two important functional characteristics of normal phonatory posture. In the treatment of unilateral vocal cord paralysis, vocal fold medialization improves closure, facilitating entrainment of both vocal folds for improved phonation, and reinnervation is purported to maintain vocal fold bulk and stiffness. A comb...
