OBJECTIVE: High-speed video (HSV) imaging of vocal fold vibration has been possible only through the rigid endoscope. This study reports that a fiberscope-based high-speed imaging system may allow HSV imaging of naturalistic voicing. MATERIALS AND METHODS: Twenty-two subjects were recorded using a commercially available black and white high-speed camera (Photron Motion Tools, 256 × 120 pixel, 2000 frames per second, 8 second acquisition time). The camera gain is set to +6 db...

Posterior glottic stenosis (PGS) is a rare but life-threatening condition mostly caused by damage to the interarytenoid mucosa by an endotracheal tube. In surgical treatment of PGS, airway patency is prioritized, and the laryngeal functions involved in swallowing and phonation are considerably sacrificed. In the majority of cases, lateralization of a vocal fold or partial excision of a vocal fold and arytenoid cartilage results in glottal closure insufficiency and deterioration of phonatory function. We present the first report of transcricothyroid endoscopic subglottic surgery to treat a 46-year-old man with PGS who was intubated for 10 days...

BACKGROUND: Measurement of treatment outcomes is critical for the spectrum of voice treatments (ie, surgical, behavioral, or pharmacological). Outcome measures typically include visual (eg, stroboscopic data), auditory (eg, Consensus Auditory-Perceptual Evaluation of Voice; Grade, Roughness, Breathiness, Asthenia, Strain), and objective correlates of vocal fold vibratory characteristics, such as acoustic signals (eg, harmonics-to-noise ratio, cepstral peak prominence) or patient self-reported questionnaires (eg, Voice Handicap Index, Voice-Related Quality of Life)...

OBJECTIVE: To identify Helicobacter pylori infection in tonsillar tissue samples from patients undergoing tonsillectomy for chronic tonsillitis versus tonsillar hypertrophy, and to assess the possible relationships between H pylori and patients' sociodemographic data and laryngopharyngeal reflux. METHODS: In this prospective study, 97 patients who underwent tonsillectomy were divided into the following 2 groups: patients with chronic tonsillitis (n = 62) and patients with tonsillar hypertrophy (control group; n = 35)...

The objective of the study was to determine the etiology and subsequent management of patients with unilateral vocal fold immobility (UVFI) and compare our results with other such studies. This was a retrospective case series of all patients that were treated for UVFI at one single tertiary referral centre between 2010 and 2014. The medical records of 161 patients over a 5-year period diagnosed with UVFI were analyzed. We looked at the patient demographics, side of immobility, etiology, management and voice assessment...

BACKGROUND: Vocal fold (VF) immobility is a rare, potentially fatal complication of advanced Parkinson's disease (PD). Previous reports suggest that subthalamic nucleus deep brain stimulation (STN-DBS) may influence laryngeal function, yet the role of STN-DBS on VF immobility remains unexplored. CASE DESCRIPTION: We report a case of a patient with advanced PD and bilateral VF immobility ultimately requiring a tracheostomy. To assess the effects of STN-DBS on vocal cord function and to correlate these effects with peripheral motor symptoms at different stimulation settings, the patient was evaluated before and after initiation of bilateral STN-DBS...

OBJECTIVE: One prospective treatment option for vocal fold scarring is regeneration with an engineered scaffold containing induced pluripotent stem cells (iPS). In the present study, we investigated the feasibility of utilizing an injectable hyaluronic acid (HA) scaffold encapsulated with human-iPS cell (hiPS) for regeneration of vocal folds. METHODS: Thirty athymic nude rats underwent unilateral vocal fold injury. Contralateral vocal folds served as uninjured controls...

Within the human larynx, the ventricular folds serve primarily as a protecting valve during swallowing. They are located directly above the sound-generating vocal folds. During normal phonation, the ventricular folds are passive structures that are not excited to periodical oscillations. However, the impact of the ventricular folds on the phonation process has not yet been finally clarified. An experimental synthetic human larynx model was used to investigate the effect of the ventricular folds on the phonation process...

Fuming Chen, Sheng Li, Yang Zhang, Jianqi Wang
The detection of the vibration signal from human vocal folds provides essential information for studying human phonation and diagnosing voice disorders. Doppler radar technology has enabled the noncontact measurement of the human-vocal-fold vibration. However, existing systems must be placed in close proximity to the human throat and detailed information may be lost because of the low operating frequency. In this paper, a long-distance detection method, involving the use of a 94-GHz millimeter-wave radar sensor, is proposed for detecting the vibration signals from human vocal folds...

OBJECTIVE: Vocal fold movement impairment (VFMI) due to neuronal injury occurs in 20% to 30% of surgeries in the region of the aortic arch. Early injection laryngoplasty can aid with postoperative pulmonary toilet in these high-risk cardiovascular patients. The purpose of this study is to determine whether continuing antiplatelet and anticoagulation therapy during awake transcervical injection laryngoplasty surgery is safe, and if there is any increase in bleeding complications in these patients...

REVIEW
Tanaya Walimbe, Alyssa Panitch, Preeti M Sivasankar
Vocal fold scarring is a common cause of dysphonia. Current treatments involving vocal fold augmentation do not yield satisfactory outcomes in the long term. Tissue engineering and regenerative medicine offer an attractive treatment option for vocal fold scarring, with the aim to restore the native extracellular matrix microenvironment and biomechanical properties of the vocal folds by inhibiting progression of scarring and thus leading to restoration of normal vocal function. Hyaluronic acid is a bioactive glycosaminoglycan responsible for maintaining optimum viscoelastic properties of the vocal folds and hence is widely targeted in tissue engineering applications...

OBJECTIVES: Development of a noninvasive method for separating different vocal fold diseases is an important issue concerning vocal analysis. Due to the time variations along a pathologic vocal signal, application of dynamic pattern modeling tools is expected to help in the detection of defects that occur in the speech production mechanism. MATERIALS AND METHODS: In the present study, the hidden Markov model, which is a state space model, is employed to sort some of the vocal diseases...

High-speed videoendoscopy captures the cycle-to-cycle vibratory motion of each individual vocal fold in normal and severely disordered phonation. Therefore, it provides a direct method to examine the specific vibratory changes following vocal fold surgery. The purpose of this study was to examine the vocal fold vibratory pattern changes in the surgically treated pathologic vocal fold and the contralateral vocal fold in three vocal pathologies: vocal polyp (n = 3), paresis or paralysis (n = 3), and scar (n = 3)...
