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...

INTRODUCTION: Vocal fold cysts are benign mid-membranous lesions of the true vocal fold, classified as mucus retention or epidermal inclusion cysts. Treatment is surgical excision with or without postoperative voice therapy. METHODS: A retrospective review was performed of the demographics, treatment approach, and outcomes of patients treated for vocal fold cysts between 2009 and 2014. Voice Handicap Index (VHI)-10 scores before and after treatment were compared using the Wilcoxon Rank-Sum test and the two-tailed Student's t test...

Vocal fold microstructure is complex and can be affected by laryngeal microsurgery, inducing scarring that prevents mechanical uncoupling of epithelium and muscle, leading to vibration disorder and disabling dysphonia. Treatment options presently are few, and often without efficacy for vibration, having only an impact on volume to reduce glottal closure defect. The present review of the literature had two aims: (i) to report the current state of the literature on cell therapy in vocal fold scarring; and (ii) to analyze the therapeutic interest of the adipose-derived stromal vascular fraction in the existing therapeutic armamentarium...

BACKGROUND: Vocal fold movement impairment (VFMI), a known complication following thoracic aortic surgery, has been associated with poorer surgical outcomes, including higher pulmonary complications and longer length of stay (LOS). Awake transcervical injection laryngoplasty in the inpatient setting serves to augment pulmonary toilet function for affected patients. This study investigates clinical outcomes of patients who underwent early versus late injection laryngoplasty following aortic surgery...

The vocal cord or vocal fold is a remarkable structure, capable to support significant physical constraints. When the voice malmenage becomes chronic, it may appear an organic alteration causing nodules, polyps or Reinke edema even a lesion of the posterior glottis, the granuloma. These lesions are benign but lead to dysphonia that can be invalidating. Treatment can be a speech therapy with correction of breath and posture and, in some cases, a surgical treatment. In this article, we describe these common lesions with their histological characteristics and pathophysiological hypotheses which lead to their appearance and treatment...

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...

REVIEW
Friedrich Ladich, Hans Winkler
Sound propagates much faster and over larger distances in water than in air, mainly because of differences in the density of these media. This raises the question of whether terrestrial (land mammals, birds) and (semi-)aquatic animals (frogs, fishes, cetaceans) differ fundamentally in the way they communicate acoustically. Terrestrial vertebrates primarily produce sounds by vibrating vocal tissue (folds) directly in an airflow. This mechanism has been modified in frogs and cetaceans, whereas fishes generate sounds in quite different ways mainly by utilizing the swimbladder or pectoral fins...

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...

Importance: Infants with vocal-fold motion impairment (VFMI) have an increased risk of aspiration and pulmonary complications. Flexible nasolaryngoscopy (FNL) is the gold standard for evaluation of vocal-fold mobility. Although safe, FNL causes measurable physiologic changes. Noxious stimuli, especially in neonates in the cardiovascular intensive care unit, may cause imbalance between the pulmonary and systemic circulations and potentially circulatory collapse. Objective: To examine whether bedside measurement of infant cry volume using a smartphone application can be a screening tool for vocal-fold movement in FNL...

BACKGROUND: It is crucial to find a balance between functional and oncological outcome when choosing an adequate method for the management of vocal fold leukoplakia. Therefore, a detailed examination is a milestone in the decision-making process. AIM: To examine whether narrow-band imaging (NBI) can be helpful in vocal fold assessment in the case of leukoplakia and how to overcome the "umbrella effect"- understood as the submucosal vascular pattern hidden under the plaque...
