Estimation of Subglottal Pressure From Neck Surface Vibration in Patients With Voice Disorders.

J Speech Lang Hear Res 2020 Jul 1:1-17. Epub 2020 Jul 1.

Center for Laryngeal Surgery and Voice Rehabilitation, Massachusetts General Hospital, Boston.

Purpose Given the established linear relationship between neck surface vibration magnitude and mean subglottal pressure (Ps) in vocally healthy speakers, the purpose of this study was to better understand the impact of the presence of a voice disorder on this baseline relationship. Method Data were obtained from participants with voice disorders representing a variety of glottal conditions, including phonotraumatic vocal hyperfunction, nonphonotraumatic vocal hyperfunction, and unilateral vocal fold paralysis. Participants were asked to repeat /p/-vowel syllable strings from loud-to-soft loudness levels in multiple vowel contexts (/pa/, /pi/, /pu/) and pitch levels (comfortable, higher than comfortable, lower than comfortable).

Influence of level difference due to vocal folds angular asymmetry on auto-oscillating replicas.

J Acoust Soc Am 2020 Feb;147(2):1136

LEGI, UMR CNRS 5519, Grenoble Alpes University, France.

Dysphonia is often caused by level difference between left and right vocal folds, which are positioned on different angles with respect to the transverse plane, resulting in angular asymmetry. Unilateral vocal fold paralysis may cause such angular asymmetry. In this case, the normal vocal fold is located on the transverse plane, whereas the paralyzed vocal fold is rotated in the sagittal plane as its posterior edge is moved up to the superior direction.

While Ansa to recurrent laryngeal nerve reinnervation is gaining popularity in the treatment of unilateral vocal fold immobility, little has been reported on commonly encountered surgical challenges with this procedure. Here, we present a cohort of 21 pediatric patients who underwent this procedure with a full description of techniques used to overcome common challenges with this procedure. We report vocal and swallowing outcomes for these patients, with an overall success rate of 19/21 (90. Read More

Study protocol to develop a patient-reported outcome measuring disability associated with unilateral vocal fold paralysis: a mixed-methods approach with the CoPE collaborative.

BMJ Open 2019 10 30;9(10):e030151. Epub 2019 Oct 30.

Division of Otolaryngology, Department of Surgery, University of Wisconsin, Madison, Wisconsin, USA.

Introduction: Patient-reported outcome (PRO) measures are increasingly developed with multisite, representative patient populations so that they can serve as a primary endpoint in clinical trials and longitudinal studies. Creating multisite infrastructure during PRO measure development can facilitate future comparative effectiveness trials. We describe our protocol to simultaneously develop a PRO measure and create a collaborative of tertiary care centres to address the needs of patients with unilateral vocal fold paralysis (UVFP).

Compensatory Movement of Contralateral Vocal Folds in Patients With Unilateral Vocal Fold Paralysis.

J Voice 2019 Oct 22. Epub 2019 Oct 22.

Division of Otolaryngology-Head and Neck Surgery, Department of Surgery, University of Wisconsin-Madison School of Medicine and Public Health, Madison, Wisconsin.

Objectives: Previous studies of subjects with unilateral vocal fold paralysis (UVFP) as observed in a positron emission tomography-computed tomography (PET-CT) examination have demonstrated false positive results in the contralateral cricoarytenoid, in which the metabolism may be higher. This area may also be the site of contralateral compensatory movement in these patients. In this study, we compared the adduction speed of the contralateral vocal folds in patients with UVFP and in healthy subjects as measured by the stroboscopic laryngoscope frame rate. Read More

Breathiness and Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) in Patients Undergoing Medialization Laryngoplasty With or Without Arytenoid Adduction.

J Voice 2019 Oct 9. Epub 2019 Oct 9.

Mayo Clinic Department of Otolaryngology, Rochester, Minnesota. Electronic address:

Objectives: We hypothesized that, in patients with unilateral vocal fold paralysis (UVFP), the auditory-perception of breathiness measured with Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) would be higher preoperatively in patients who undergo medialization laryngoplasty (ML) with arytenoid adduction (AA) compared to ML alone. We further hypothesized that increased breathiness would correlate with increased glottal area at maximum glottal closure.

Study Design: Retrospective chart review. Read More

Evaluation of Diffusional Characteristics and Microstructure in Unilateral Vocal Fold Paralysis Using Diffusion Tensor Imaging.

Ear Nose Throat J 2019 Sep 24:145561319874721. Epub 2019 Sep 24.

Department of ENT, Zhongshan Hospital, Xiamen University, Xiamen, China.

Objective: To investigate the value of diffusion tensor imaging (DTI) in the evaluation of vocal fold tissue microstructure after recurrent laryngeal nerve (RLN) injury.

Methods: Six canines were divided into 2 groups: a unilateral vocal fold paralysis group (n = 4) and a control group (n 2). The RLN was cut in the unilateral vocal fold paralysis group, and no intervention was applied in the control group. Read More

[The value of acoustic parameters in the voice therapy for patients with unilateral vocal cord paralysis].

Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi 2019 Sep;54(9):685-688

Department of Otorhinolaryngology Head and Neck Surgery, Tianjin First Central Hospital, Tianjin Institute of Otorhinolaryngology, Tianjin 300192, China.

To investigate the value of acoustic parameters in the voice therapy for patients with unilateral vocal cord paralysis (UVCP). From May 2015 to April 2018, 51 patients with UVCP and 59 healthy controls in Department of Otorhinolaryngology Head and Neck Surgery, Tianjin First Central Hospital, were involved in this research retrospectively.

Recurrent laryngeal nerve transection in mice results in translational upper airway dysfunction.

J Comp Neurol 2020 Mar 18;528(4):574-596. Epub 2019 Oct 18.

Department of Biomedical Sciences, University of Missouri, Columbia, Missouri.

The recurrent laryngeal nerve (RLN) is responsible for normal vocal-fold (VF) movement, and is at risk for iatrogenic injury during anterior neck surgical procedures in human patients. Injury, resulting in VF paralysis, may contribute to subsequent swallowing, voice, and respiratory dysfunction. Unfortunately, treatment for RLN injury does little to restore physiologic function of the VFs. Read More

Pathophysiology of iatrogenic and idiopathic vocal fold paralysis may be distinct.

Laryngoscope 2020 Jun 9;130(6):1520-1524. Epub 2019 Sep 9.

Sean Parker Institute for the Voice, Department of Otolaryngology-Head & Neck Surgery, Weill Cornell Medical College, New York, New York, U.S.A.

Objective: Spontaneous vocal recovery from idiopathic vocal fold paralysis (VFP) appears to differ in time course from recovery in iatrogenic VFP. This study aimed to determine if this difference could be explained by differing mechanisms causing recurrent laryngeal nerve (RLN) dysfunction, specifically whether idiopathic VFP is consistent with a focal RLN axonal lesion.

Study Design: Case series with mathematical modeling. Read More

Does Dysphagia Improve Following Laryngeal Reinnervation for Treatment of Hoarseness in Unilateral Vocal Fold Paralysis?

J Voice 2019 Sep 3. Epub 2019 Sep 3.

Department of Otolaryngology, Head and Neck Surgery, University of Washington Medical Center, Seattle, Washington.

Purpose: There are many reports of the efficacy of laryngeal reinnervation on voice, but there is a paucity of literature regarding its impact on swallowing function. The goal of this study was to explore the impact of laryngeal reinnervation on swallowing outcomes among unilateral vocal fold paralysis (UVFP) patients.

Methods: We reviewed 22 UVFP cases treated with laryngeal reinnervation at our institution. Read More
