Aerodynamic Parameters and the Airflow Regression Slope (ARS) in Patients with Vocal Polyps before and after Laryngomicrosurgery according to Perceptual Judgment
Phonation occurs when vocal fold vibrations are initiated and maintained by an interaction between the respiratory and phonatory systems [1]. The vocal folds must be in good condition for the voice to be satisfactory. Pathological conditions of the vocal folds are associated with voice deterioration. Voice disorders include alterations in vocal fold closure or muscle activation during vocal fol...
متن کاملAerodynamic and acoustic features of vocal effort.
OBJECTIVES The purpose of this study was to determine the aerodynamic and acoustic features of speech produced at comfortable, maximal and minimal levels of vocal effort. STUDY DESIGN Prospective, quasi-experimental research design. METHOD Eighteen healthy participants with normal voice were included in this study. After task training, participants produced repeated syllable combinations at...
متن کاملTreatment of Hemorrhagic Vocal Polyps by Pulsed Dye Laser-Assisted Laryngomicrosurgery
OBJECTIVE Conventional surgical techniques of laryngomicrosurgery (LMS) on hemorrhagic vocal polyps are often difficult due to obscuration of the surgical field by inadvertent bleeding from the lesion, and there are often significant amounts of mucosal epithelium loss. Here, we introduce our surgical technique using pulsed dye laser (PDL), which can effectively resect the polyp with vocal fold ...
متن کاملPersistent Dysphonia after Laryngomicrosurgery for Benign Vocal Fold Disease
OBJECTIVES Laryngomicrosurgery (LMS) is used to manage most vocal fold lesions. However, the functional voice outcome of the LMS might be diverse due to the influence of various factors. We intend to evaluate the incidence and etiologic factors of persistent dysphonia after LMS for benign vocal fold disease (BVFD). METHODS We performed a retrospective review of 755 patients who underwent LMS ...
متن کاملDiscriminating speakers with vocal nodules using aerodynamic and acoustic features
This paper demonstrates that linear discriminant analysis using aerodynamic and acoustic features is effective in discriminating speakers with vocal-fold nodules from normal speakers. Simultaneous aerodynamic and acoustic measurements of vocal function were taken of 14 women with bilateral vocal-fold nodules and 12 women with normal voice production. Features were extracted from the glottal air...
