Alveolar trills are sounds produced by the self-oscillation of the tongue tip in the alveolar region. Specific aeroacoustic conditions around the lingual constriction are required to produce such sounds, but have not been fully investigated dueto the lack of physical modeling. This study discusses the possibility to model the tongue tip behavior with lumped mass-spring systems similar to those ...

High Resolution Laryngeal Ultrasound for diagnosis of vocal cords lesions

UNLABELLED A longitudinal cohort study Introduction: Voice change may be defined as a group of changes in voice pattern that take place between childhood and puberty. During this period some vocal cord lesions (specifically cysts and nodules) may undergo transformation. AIM To evaluate changes in vocal cord structural lesions following voice changes. MATERIAL AND METHOD All laringoscopic ex...

OBJECTIVE To conduct a prospective randomized controlled trial describing and investigating the efficacy and safety of radiosurgical excision of benign superficial vocal fold lesions. MATERIALS AND METHODS Fifty patients with benign superficial vocal fold lesions (20 vocal nodules, 27 vocal polyps and three Reinke's oedema) who failed conservative therapy were included in the study. They were...

BACKGROUND Acquired benign vocal fold lesions are among the most common causes of voice problems. Since the local impact of estrogen and progesterone receptors in laryngeal tissue is discussed controversially, the presence of sex hormone receptors in benign vocal fold alterations needs to be clarified. GOAL OF THE STUDY To investigate the expression of estrogen-alpha receptors (ER-alpha), est...

OBJECTIVE The aim of this study is to evaluate the value of high resolution ultrasonography (HRUS) in diagnosis of various laryngeal lesions which already diagnosed with rigid endoscopy. STUDY DESIGN Prospective study with control group. PATIENTS AND METHODS Sixty-six patients were suffering from throat symptoms and pre-examined by rigid endoscopy under local anesthesia and diagnosed to hav...
