Laryngeal pathologies in dysphonic children with Down Syndrome.

Int J Pediatr Otorhinolaryngol 2022 Jun 26;157:111118. Epub 2022 Mar 26.

Department of Otolaryngology and Communication Enhancement, Boston Children's Hospital, Boston, MA, USA; Department of Otolaryngology, Harvard Medical School, Boston, MA, USA.

Introduction: Down syndrome is the most common chromosomal abnormality and is associated with a higher incidence of congenital heart defects, which often require surgery within the first year of life. Previous studies have found that children with Down syndrome are at higher risk for subglottic stenosis, vocal fold paralysis, and laryngomalacia. The goal of this study is to review children with Down syndrome presenting with dysphonia and to characterize their laryngeal pathologies. Read More

IMP3 Protein Overexpression Is Linked to Unfavorable Outcome in Laryngeal Squamous Cell Carcinoma.

Cancers (Basel) 2021 Aug 26;13(17). Epub 2021 Aug 26.

Institute of Head and Neck Diseases, Evangelical Hospital, 1180 Vienna, Austria.

Background: The aim of this study was to (i) determine IMP3 protein expression in benign and malignant laryngeal lesions, (ii) compare its expression to Ki-67, p53, cyclin D1, and (iii) finally, to examine the prognostic power of IMP3 in squamous cell carcinomas of the larynx (LSSC).

J Voice 2021 Jul 17. Epub 2021 Jul 17.

Department of Otolaryngology-Head and Neck Surgery, Kyoto Prefectural University of Medicine, Kyoto, Japan.

Objectives: Local injection of glucocorticoids (GCs) into the vocal folds has been used for treating the vocal fold lesions. While the positive effects on vocal fold nodules, polyps, or scarring have been clinically reported, some concern remains around the potential adverse effects such as vocal fold atrophy, and the mechanisms remain unclear. The present study examined the histology and gene expression of locally injected GC into the vocal folds in rats. Read More

Differences Between Female Singers With Phonotrauma and Vocally Healthy Matched Controls in Singing and Speaking Voice Use During 1 Week of Ambulatory Monitoring.

Am J Speech Lang Pathol 2021 01 20;30(1):199-209. Epub 2021 Jan 20.

Massachusetts General Hospital, Boston.

Purpose Previous ambulatory voice monitoring studies have included many singers and have combined speech and singing in the analyses. This study applied a singing classifier to the ambulatory recordings of singers with phonotrauma and healthy controls to determine if analyzing speech and singing separately would reveal voice use differences that could provide new insights into the etiology and pathophysiology of phonotrauma in this at-risk population. Method Forty-two female singers with phonotrauma (vocal fold nodules or polyps) and 42 healthy matched controls were monitored using an ambulatory voice monitor. Read More

Predominant Vertical Location of Benign Vocal Fold Lesions by Sex and Music Genre: Implication for Pathogenesis.

Laryngoscope 2021 07 9;131(7):E2284-E2291. Epub 2021 Jan 9.

Tokyo Voice Center, International University of Health and Welfare, Tokyo, Japan.

Objectives/hypothesis: Vertical locations of vocal fold mucosal lesions (VFMLs) vary along the free edge. As the vertical contact area of vocal folds (VFs) depends on the vocal register, lesions may occur in the contact area of more frequently used vocal registers. This study investigated the cause of location variations by comparing the vertical sites of VFMLs in singers of both sexes with different music genres. Read More

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.

Voice Therapy for Benign Voice Disorders in the Elderly: A Randomized Controlled Trial Comparing Telepractice and Conventional Face-to-Face Therapy.

J Speech Lang Hear Res 2020 07 24;63(7):2132-2140. Epub 2020 Jun 24.

Department of Otolaryngology-Head and Neck Surgery, Far Eastern Memorial Hospital, Taipei, Taiwan.

Purpose Previous studies have reported that voice therapy via telepractice is useful for patients with nodules and muscle tension dysphonia. Nevertheless, telepractice for elderly patients with voice disorders has not yet been investigated. We conducted this study to examine the hypothesis that voice therapy via telepractice is not inferior to conventional voice therapy. Read More

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.

Anxiety and depression in patients with vocal fold nodules, edema and polyps.

Eur Arch Otorhinolaryngol 2020 Sep 30;277(9):2493-2500. Epub 2020 Apr 30.

Clinic of Otorhinolaryngology and Maxillofacial Surgery, Clinical Centre of Serbia, Pasterova 2, 11000, Belgrade, Serbia.

Purpose: To compare the prevalence and severity of depression and anxiety among patients with vocal fold (VF) nodules, polyps and edema. At the same time the aim was to analyse association between severity of distress and the level of vocal handicap as well as to identify other factors related to severity of depression and anxiety in these patients.

Methods: To all participants were given five questionnaires: (1) questionnaire on socio-demographic and some other characteristics of patient; (2) Beck's Depression Inventory (BDI); (3) State-Trait Anxiety Inventory (STAI) 1 (State Anxiety); (4) STAI 2 (Trait Anxiety); and (5) Voice Handicap Index (VHI)-10.

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

J Voice 2021 Jul 24;35(4):665.e7-665.e12. Epub 2020 Mar 24.

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
