In this study, laryngeal flow fields are investigated and compared in normal larynx and models of larynx with unilateral vocal fold paralysis (UVFP). In paralytic models, three fixed initial glottal gaps are considered to understand the positive or probable negative impacts of surgical operation on unilaterally paralytic larynx, by which the paralyzed vocal fold is brought closer to the mid-plane. Various features of the flow fields have been discussed in detail including glottal gap width, glottal flow rate, glottal exit pressure pattern and glottal jet evolution...

INTRODUCTION: Bilateral vocal folds' immobility is a challenge in laryngology. Multiple procedures have been proposed to improve breathing by statically enlarging the glottal airway, what also results in loss of voice and aspiration. We proposed a technique to enlarge the posterior glottis by rotating the arytenoids on its axis, imitating the function of the posterior cricoarytenoid muscle, with the objective of evaluating the results regarding decannulation, voice quality, and bronchoaspiration...

PURPOSE: With adequate indication and meticulous execution, endoscopic procedures can efficiently treat a subset of adult and pediatric benign laryngotracheal stenosis and obstructions, but these procedures are precise and very demanding. The difference between a successful and a failed surgery, with potentially debilitating side effects, resides in small details. The learning curve is long and very few centers worldwide have a sufficient case load making adequate training difficult. While indications and concepts of endoscopic procedures can be learned in books and by observing trained colleagues, the dexterity and the precise realization need to be practiced, ideally not initially on patients...

Background: Paralysis of one vocal fold leads to glottal gap and vocal fold insufficiency that has significant impact upon a patient's quality of life. Fillers have been tested to perform intracordal injections, but they do not provide perdurable results. Early data suggest that enriching fat grafts with adipose-derived regenerative cells (ADRCs) promote angiogenesis and modulate the immune response, improving graft survival. The aim of this study is to propose ADRC-enriched adipose tissue grafts as effective filler for the paralyzed vocal fold to use it for functional reconstruction of the glottal gap...

PURPOSE: Endoscopic partial arytenoidectomy (EPA) is one of the static operations for treatment of bilateral vocal fold paralysis (BVFP). Improvement in airway may cause voice loss and aspiration. The author reports his experience on EPA using medially based mucosal flap to enlarge posterior glottis without removing any part of membranous vocal fold. MATERIALS AND METHODS: Sixty-four consecutive patients with BVFP underwent EPA. Pre- and postoperative evaluations included Voice Handicap Index-30, aerodynamic and acoustic analysis, flow volume loops, perceptual evaluation of pre- and postoperative voice using grade, roughness, breathiness, asthenia, strain (GRBAS) scale, speech intensity, breathing ability evaluation, and functional outcome swallowing scale...

Introduction Laryngeal paralysis deteriorates all laryngeal functions. Therefore the therapeutic process must include restoration of respiratory, defensive and vocal function. Selection of a proper rehabilitation path plays a key role. Appropriate research protocol that includes objective methods of voice evaluation is an important element of monitoring the return of vocal efficiency. Voice efficiency is important for the patient particularly due to psychological and social reasons. Aim The aim of the study was the assessment of short-term functional voice therapy (FVT) in patients with unilateral paralysis of the larynx with the usage of objective parameters describing the glottis and voice quality...
