Objectives: Our previous work has shown that the symmetric, smooth, convergent shape of the subglottis reduces turbulent airflow at the glottal entrance. Medialization thyroplasty may alter the glottal shape and is very likely to introduce some degree of glottal asymmetry, which could result in increased turbulence and a reduction in voice quality. This study reports the effects of medializing and not medializing the subglottis in silicone models of human cadaveric larynges. Methods: In…

Influence of Tracheal stenosis on Vocal Fold Vibration: A case report
Tracheal stenosis affects the mechanism of vocal fold vibration, which is reversed after tracheal dilatation with subsequent improvement of vocal Fold vibration.
Effect of inferior surface angle on the self-oscillation of a computational vocal fold model.
Structural, rather than aerodynamic, effects are shown to be the cause of the changes in model response as the inferior surface angle was varied and glottal width and air flow rate waveforms changed.
A Silicone Human Head Model for Testing Acoustic Properties of the Upper Airway
The purpose of this project is to create an actual-size, anatomically accurate human head model that contains a void for the upper airway. The model is intended to be used for studying the acoustic
Excised larynx evaluation of subthyroid cartilage approach to medialization thyroplasty
An alternative approach to medialization thyroplasty involving dissection underneath the thyroid cartilage with placement of a Gore‐Tex implant is described and its effect on a range of phonatory measures using an excised canine larynx model is evaluated.
Investigating the effects of laryngotracheal stenosis on upper airway aerodynamics
This study investigates the effect of LTS on airway resistance and volumetric flow across three different inspiratory pressures.
Modulating phonation through alteration of vocal fold medial surface contour

Role of Subglottal Shape in Turbulence Reduction
The smooth converging shape of the subglottis can produce a significant reduction in turbulence, and these findings may have important voice implications for operations that may change theSubglottal shape.
Multidimensional assessment of functional outcomes of medialization thyroplasty
Results of the present investigation confirm the functionality and effectiveness of MT in patient voice rehabilitation with UVFP, but the means of acoustic voice parameters measured in the study did not reach normal limits, probably because of the remaining underlying condition of UVFP.
Laryngeal framework surgery: a proposal for classification and nomenclature by the Phonosurgery Committee of the European Laryngological Society
The Phonosurgery Committee of the European Laryngological Society has developed a new terminology for laryngeal framework surgery, which should provide a general framework suited not only to classify the current techniques but also to easily apply and adapt to include new procedures and future developments as necessary.
Acoustic Analysis of Autologous Fat Injection versus Thyroplasty in the Same Patient
This study showed that both techniques can return the voice to preparalytic values after both treatments, and showed that the voice improved to a greater extent after fat injection.
Recent Modifications in Thyroplasty Type I
Modifications were made in the technique of thyroplasty type I, including cutting the calcified cartilage with minimal intervention in the soft tissue, and overmedialization of the vocal cord.
Vortical Flow Field during Phonation in an Excised Canine Larynx Model
These vortical structures were consistently found during specific phases of the glottal cycle for 3 canine larynges that significantly varied in size, suggesting that the vortices may be important for both vibration and sound production; however, further study is needed to prove this.
Longitudinal Evaluation of Vocal Function After Thyroplasty Type I in the Treatment of Unilateral Vocal Paralysis
Parameter changes of vocal efficiency and stability after primary thyroplasty type I showed significant improvement and remained stable as early as 1 month postoperatively, with only slight fluctuations over a 6‐month period.

A theory of interaction between the source of sound in phonation and the vocal tract filter is developed and positive reinforcement of the harmonics by supraglottal inertive reactance (and to a lesser degree by subglottal compliant reactance) is shown to be influenced by interaction.
Longitudinal voice quality changes following isshiki thyroplasty type I: The yale experience
Longitudinal voice quality changes following Isshiki thyroplasty type I were investigated in a group of 18 patients exhibiting unilateral vocal fold paralysis, observing significantly higher voice fundamental frequency, significantly louder voice intensity, and significantly longer maximum phonation time.
