Vocal Fold Collision Speed in vivo: The Effect of Loudness.

J Voice 2020 Sep 28. Epub 2020 Sep 28.

Institute of Neurosciences, University of Louvain, Brussels, Belgium. Electronic address:

Mechanical impact stress on the vocal fold surface, particularly when excessive, has been postulated to cause the so-called phonotraumatic tissue lesions, such as nodules and polyps. The collision stress between the vocal folds depends on the vocal fold velocity at the time of impact. Hence this vocal fold collision speed is a relevant parameter when considering biomechanical economy of phonation, especially in voice professionals needing a louder voice than normal. Read More

Intrinsic Laryngeal Lipoma Treated with Transoral CO₂ Laser Microsurgery: An Unusual Case Report.

Am J Case Rep 2020 Jul 3;21:e920528. Epub 2020 Jul 3.

Ear, Nose and Throat (ENT) Unit, Department of General and Specialized Surgery, AOU University of Campania "Luigi Vanvitelli", Napoli, Italy.

BACKGROUND Lipomas, the most common soft tissue tumors, represent almost half of all benign mesenchymal neoplasms and are characterized by the absence of symptoms. However, if they grow in a laryngeal site, they can cause dyspnea and dysphonia which represents one of the major symptoms of benign laryngeal diseases (such as polyps or nodules); these symptoms are often the first symptom of neoplastic diseases. CASE REPORT We present a case of a 28-year-old female patient with a rounded pseudocyst neoformation located in the left aryepiglottic fold that partially hid the homolateral vocal cord and limited its mobility.

High-Resolution Laryngeal US: Imaging Technique, Normal Anatomy, and Spectrum of Disease.

Radiographics 2020 May-Jun;40(3):775-790

From the Department of Imaging, University College London Hospitals, London, England (T.B., S.M.); Department of Otorhinolaryngology, Royal National Throat, Nose and Ear Hospital, 330 Gray's Inn Road, Kings Cross, London WC1X 8DA, England (V.M.T.); and Serviço de Radiologia, Instituto Português de Oncologia de Lisboa Francisco Gentil, Lisbon, Portugal (M.H.).

Although US is one of the most used modalities for head and neck imaging, its use in the diagnosis of laryngeal abnormalities is much less widespread. The standard assessment of laryngeal abnormalities currently involves direct laryngoscopy and cross-sectional imaging (either CT or MRI) but rarely US. US is readily available, noninvasive, and radiation free, and it allows real-time imaging (with video for dynamic assessment), higher resolution than that of cross-sectional imaging, and the performance of targeted fine needle aspiration cytology or biopsy.

Videolaryngoscopy Quality with Protective Cover of Intraoral Odontologic Camera Evaluation in Vocal Fold Coverage Lesions.

J Voice 2020 Mar 23. Epub 2020 Mar 23.

Brazilian Red Cross Hospital, Branch of Paraná, Lauro Grein Study Center, Curitiba, Paraná, Brazil.

Introduction: The examination of the larynx with indirect visualization is one of a series of steps in otorhinolaryngological evaluation. In the past this exam was performed more commonly with mirrors and headlights, but for at least the last four decades physicians have resorted to assessing the laryngopharynx with both rigid and fiberoptic instruments. The rigid 70° laryngoscope is the most used in our practice, its main drawback being the time-consuming resterilization process needed between scope usages in different patients. Read More

Toward Development of a Vocal Fold Contact Pressure Probe: Bench-Top Validation of a Dual-Sensor Probe Using Excised Human Larynx Models.

Appl Sci (Basel) 2019 Oct 16;9(20). Epub 2019 Oct 16.

Center for Laryngeal Surgery and Voice Rehabilitation, Massachusetts General Hospital, Boston, MA 02114, USA.

A critical element in understanding voice production mechanisms is the characterization of vocal fold collision, which is widely considered a primary etiological factor in the development of common phonotraumatic lesions such as nodules and polyps. This paper describes the development of a transoral, dual-sensor intraglottal/subglottal pressure probe for the simultaneous measurement of vocal fold collision and subglottal pressures during phonation using two miniature sensors positioned 7.6 mm apart at the distal end of a rigid cannula.

Vocal fold nodules: A disorder of phonation organs or auditory feedback?

Clin Otolaryngol 2019 11 11;44(6):975-982. Epub 2019 Sep 11.

Faculty of Medicine, School of Medicine, National Yang-Ming University, Taipei, Taiwan.

Objective: Increasing evidence supports that auditory feedback of one's own voice closely relates to real-time adjustments of vocal control. Previous studies highlighted that the low-frequency modulations of below 3 Hz (LFM) embedded in vocal fundamental frequency (F0) showed a reflex-like response to altered auditory inputs. However, the auditory feedback control of different vocal disorders remains unclear. Read More
