Glottal insufficiency (GI) is a cause of breathy voice that can profoundly affect quality of voice. Main causes are unilateral vocal fold paralysis or endoscopic cordectomy for the early treatment of laryngeal cancer of the glottis. The main strategy in surgical treatment is type I medialization thyroplasty according to Isshiki with the use of implants e.g. silastic, hydroxyapatite, titanium, Gore-Tex or Montgomery. Other procedures are arytenoid adduction, the injection laryngoplasty via thyrohyoid and cricothyroid approach and laryngeal reinnervation...

Unilateral vocal fold paralysis (UVP) occurs related to recurrent laryngeal nerve (RLN) impairment associated with impaired swallowing, voice production, and breathing functions. The majority of UVP cases occur subsequent to surgical intervention with approximately 12-42% having no known cause for the disease (i.e., idiopathic). Approximately 2/3 of those with UVP exhibit left-sided injury with the average onset at 50 years of age or older in those diagnosed as idiopathic. Given the association between the RLN and the subclavian and aortic arch vessels, we hypothesized that changes in vascular tissues would result in increased aortic compliance in idiopathic left-sided UVP patients compared to those without UVP...

Medialization thyroplasty (type I) is surgical procedure performed on the thyroid cartilage. The major indication for this surgery is significant glottis insufficiency due to unilateral vocal fold paresis. However the proce¬dure is also performed after vocal fold resections during cordectomy. THE AIM: The evaluation of voice results in patients after medialisation throplasty. MATERIAL AND METHODS: In Otolaryngology Department of Medical University of Warsaw there were performed so far 8 thyroplasty procedures under local anaesthesia with implantation of medical silicon protesis...

OBJECTIVES: This retrospective study was carried out to investigate the effectiveness and safety of office-based electromyography-guided injection of botulinum toxin in the cricopharyngeus muscle of patients who did not show upper esophageal sphincter passage in a swallowing study in spite of maximal swallowing rehabilitation. METHODS: Thirty-six patients who showed no or limited ability to oral feed after maximum swallowing rehabilitation were enrolled. Video fluoroscopic swallowing study, flexible endoscopic evaluation of swallowing, disability rating scale, penetration aspiration score, and National Institutes of Health swallowing safety scale were used in the evaluation of dysphagia...

OBJECTIVES: Although a variety of therapeutic techniques have been suggested for patients with unilateral adductor vocal fold paralysis (UAVFP), they were not aimed specifically at determining the efficacy of early intervention for these patients. The purposes of this study are to explore a protocol of voice therapy and to investigate its efficacy in voice therapy for patients with early UAVFP. A 12-week planned voice therapy protocol, including vocal function exercise, hard attack, and resonance voice therapy, was given to 10 patients within 6 months of initial diagnosis...

OBJECTIVES: An important domain in health-related quality of life evaluations is quality of life perceptions due to having a voice disorder. The purpose of the current study was (1) to examine the correlation of the Iranian Voice Quality of Life Profile (IVQLP) with the Voice-Related Quality of Life (VRQOL) and Voice Handicap Index-30 (VHI-30) for establishing the construct convergent validity of the IVQLP, and (2) to examine the correlation between VRQOL and VHI-30. METHODS: Study sample consisted of 150 patients, 91 male and 59 female, diagnosed with muscle tension dysphonia, benign organic disorders such as polyps and nodules, and unilateral vocal fold paralysis...

In this work, a study on the efficacy of different therapeutic modalities in patients with unilateral vocal fold paralysis (UVFP) was carried out. The study included 20 patients with UVFP, divided into two groups. The objective of this work is to evaluate the voice quality in these patients and to compare the voice following surgery and voice therapy. Group I received voice therapy and group II underwent thyroplasty type I and type IV. The voice was assessed pretreatment and 1 and 3 months posttreatment. Different parameters, such as habitual fundamental frequency (F0), signal-to-noise ratio, jitter, shimmer, maximum phonation duration, s/z ratio, and objective and subjective ratings of dysphonia, were analyzed...

INTRODUCTION AND OBJECTIVE: To assess the effectiveness of electromyography-guided hyaluronic acid injection laryngoplasty in the early stage of unilateral vocal fold paralysis in terms of patient recovery from dysphonia and quality of life. METHODS: Between January and December 2014, 28 patients with unilateral vocal fold paralysis underwent electromyography and injection of hyaluronic acid in the thyroarytenoid muscle. We compared the voice handicap index, grade, roughness, breathiness, asthenia, strain scale (GRBAS), videostroboscopic parameters and maximum phonation time assessed before, 15 days and 6 months after the intervention, using the non-parametric Wilcoxon rank test...

BACKGROUND: Medialization thyroplasty and injection laryngoplasty are widely accepted treatment options for unilateral vocal fold paralysis. Although both procedures result in similar clinical outcomes, little is known about the corresponding medical care costs. Medialization thyroplasty requires expensive operating room resources while injection laryngoplasty utilizes outpatient resources but may require repeated procedures. The purpose of this study, therefore, is to quantify the cost differences in adult patients with unilateral vocal fold paralysis undergoing medialization thyroplasty versus injection laryngoplasty...

Goal. To establish a reliable instrumental system for synchronized reactivation of a unilaterally paralyzed vocal fold and evaluate its functional feasibility. Methods. Unilateral vocal fold paralysis model was induced by destruction of the left recurrent laryngeal nerve (RLN) in anesthetized dogs. With a micro controller-based electronic system, electromyography (EMG) signals from cricothyroid (CT) muscle on the ipsilateral side were recorded and used to trigger pacing of paralyzed vocalis muscles. The dynamic movement of vocal folds was continuously monitored using an endoscope, and the opening and closing of the glottis were quantified with customized imaging processing software...

Vocal fold immobility is a relatively rare complication that can occur after tracheal intubation. Differential diagnoses include a rare clinical entity called unilateral vocal fold adductor paralysis in which only branches entering the thyroarytenoid and lateral cricoarytenoid muscles of the recurrent laryngeal nerve become paralyzed. Computed tomography and laryngeal electromyography are required to distinguish this condition from others such as cricoarytenoid dislocation/subluxation. Here, we describe two patients who developed vocal fold adductor paralysis after intubation...

OBJECTIVES/HYPOTHESIS: Intralaryngeal muscle synkinesis associated with unilateral vocal fold paralysis (UVFP) is thought to preserve thyroarytenoid-lateral cricoarytenoid muscle complex tone, resulting in a better voice despite the presence of vocal fold paralysis (VFP). This study compares voice handicap in patients with unilateral VFP (UVFP) with and without evidence of adductory synkinesis on laryngeal electromyography (LEMG). STUDY DESIGN: Retrospective review of LEMG data and Voice Handicap Index-10 (VHI-10) scores of patients diagnosed with permanent UVFP...

OBJECTIVES/HYPOTHESIS: Vocal fold paresis and paralysis are common conditions. Treatment options include augmentation laryngoplasty and voice therapy. The optimal management for this condition is unclear. The objective of this study was to assess possible neuromuscular compensation mechanisms that could potentially be used in the treatment of vocal fold paresis and paralysis. STUDY DESIGN: In vivo canine model. METHODS: In an in vivo canine model, we examined three conditions: 1) unilateral right recurrent laryngeal nerve (RLN) paresis and paralysis, 2) unilateral superior laryngeal nerve (SLN) paralysis, and 3) unilateral vagal nerve paresis and paralysis...

OBJECTIVES: Dysphonia due to unilateral vocal fold paralysis (UVFP) can be characterized by hoarseness and weakness, resulting in a significant impact on patients' activity and participation. Voice therapy provided by a speech-language pathologist is designed to maximize vocal function and improve quality of life. The purpose of this paper is to systematically review literature surrounding the effectiveness of speech-language pathology intervention for the management of UVFP in adults...
