Importance: Compromised cough effectiveness is correlated with dysphagia and aspiration. Glottic insufficiency likely yields decreased cough strength and effectiveness. Although vocal fold augmentation favorably affects voice and likely improves cough strength, few data exist to support this hypothesis. Objective: To assess whether vocal fold augmentation improves peak airflow measurements during maximal-effort cough following augmentation. Setting, Design, Participants: This case series study was conducted in a tertiary, academic laryngology clinic...

Medialization laryngoplasty is the standard surgical treatment for unilateral vocal fold paralysis. This study presents a modified approach in which a thyroid cartilage graft is implanted in medialization laryngoplasty. 22 patients who underwent this approach were included in the study. The results revealed that glottal incompetence and vocal performance were markedly improved following surgery, and the follow-up period ranged from 6 to 74 months (mean, 21.4 months). Acoustic analysis revealed significant improvements in the maximum phonation time (from 3...

Bilateral true vocal fold paralysis is rarely attributable to inflammatory diseases. Sarcoidosis is a rare but important etiology of bilateral true vocal fold paralysis by compressive lymphadenopathy, granulomatous infiltration, and neural involvement. We describe the first reported case of sarcoidosis presenting as bilateral vocal fold immobility caused by direct fixation by granulomatous infiltration severe enough to necessitate tracheostomy insertion. In addition, we discuss the presentation, the pathophysiology, and the treatment of this disease with a review of the literature of previously reported cases of sarcoidosis-related vocal fold immobility...

Vocal fold paralysis (BVFP) refers to neurological causes of reduced or absent movement of one or both vocal folds. Bilateral BVFP is characterized by inspiratory dyspnea due to narrowing of the airway at the glottic level with both vocal folds assuming a paramedian position. The primary objective of intervention for BVFP is to relieve patients' dyspnea. Common clinical options for management include tracheostomy, arytenoidectomy and cordotomy. Other options that have been used with varying success include reinnervation techniques and botulinum toxin (Botox) injections into the vocal fold adductors...

Whereas static vocal fold medialization or lateralization are currently the standard procedures, new dynamic treatment methods such as reinnervation and laryngeal pacing focus on better toning and remobilization of the paralyzed vocal folds. End-to-end or jump anastomoses of the recurrent laryngeal nerve can preserve muscle mass and avoid atrophy, thus enabling subsequent dynamic therapeutic options. Prognostic evaluation and the time point of therapeutic intervention are important issues in the management of patients with recurrent laryngeal nerve paralysis...

The potential for the misinterpretation of positron-emission tomography (PET) scans in the context of a possible malignancy has been confirmed in a case report showing increased 18F-fluorodeoxyglucose (FDG) uptake after unilateral vocal fold augmentation medialization. We sought to expand these findings by investigating FDG uptake in a larger cohort of patients via a retrospective chart review. We examined the records of 15 adults-8 men and 7 women-who had undergone vocal fold augmentation for unilateral vocal fold paralysis and at least one subsequent PET scan...

The hypotheses of the present study were that the maximum frequency of fluctuation of electroglottographic (EGG) signals in the expiration phase of volitional cough (VC) reflects the cough efficiency and that this EGG parameter is affected by impaired laryngeal closure, expiratory effort strength, and gender. For 20 normal healthy adults and 20 patients diagnosed with unilateral vocal fold paralysis (UVFP), each participant was fitted with EGG electrodes on the neck, had a transnasal laryngo-fiberscope inserted, and was asked to perform weak/strong VC tasks while EGG signals and a high-speed digital image of the larynx were recorded...

OBJECTIVES/HYPOTHESIS: Patients with unilateral vocal fold paralysis (UVFP) are commonly told to wait 12 months for spontaneous recovery. This study aims to 1) determine the time to vocal recovery in UVFP, 2) use that data to develop a neurophysiologically plausible model for recovery, and 3) use the model to generate meaningful predictions for patient counseling. STUDY DESIGN: Case series with de novo mathematical modeling. METHODS: Patients with UVFP who could pinpoint a discrete onset of vocal improvement were identified...

Introduction Voice disorders caused by pseudotumors of the vocal folds or paralysis of the vocal folds with incomplete glottis closure frequently require phonomicrosurgery. These interventions were analyzed with regard to quality of voice after surgery and safety of the intervention. Methods Retrospective analysis of 400 consecutive phonomicrosurgery interventions. The following parameters were collected: distribution of pathologies of the vocal folds, rating of the voice quality by both the surgeon (RBH-system) and patient and videolaryngstroboscopy six weeks after the intervention compared to the state prior to surgery, complications and results of histological examination...

BACKGROUND: Injury to the recurrent laryngeal nerve is one of the most severe complications of thyroid surgery. Several anatomic variations of the nerve increase the likelihood of iatrogenic damage. CASE PRESENTATION: A 50-year-old woman was presented to our department with a nodule in the right thyroid lobe, and she reported no voice changes. She had no history of surgery or radiation to the head or neck. Fine-needle aspiration was recorded as papillary thyroid carcinoma...

PURPOSE: The efficacy of intraoperative nerve monitoring is controversial in the literature. This study of a single surgeon's experience seeks to determine if the use of intraoperative nerve monitoring influences recurrent laryngeal nerve injury during thyroid surgery. METHODS: Six hundred fifty-seven patients with normal pre-operative vocal fold function underwent thyroid surgery without the use of intraoperative nerve monitoring from September 1997 to January 2007, while 761 patients underwent thyroid surgery from February 2007 to February 2016 with routine use of nerve monitoring...

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...
