Identification and Remediation of Pediatric Fluency and Voice ORIGINAL ARTICLE Identification and P Remediation of H Pediatric Fluency C and Voice Disorders Barbara M. Baker, PhD, CCC-SLP, & Patricia B. Blackwell, PhD, CCC-SLP When children cannot communicate well, the difficulty often is because they have articulation or language disorders, but other difficulties also may adversely affect children’s abilities to express themselves. Prob- lems with fluency (stuttering or cluttering) and voice quality can impair communication. Pediatric nurse practitioners need to be prepared to re- spond to parents’ questions about voice and fluency issues and, when appropriate, to make referrals for evaluation and possible treatment. This article presents a basic overview of the nature of fluency and voice disorders and provides guidelines for identifying children who should be referred, and to whom.

    Vocal Cord Dysfunction JAMES DECKERT, MD, Saint Louis University School of Medicine, St. Louis, Missouri LINDA DECKERT, MA, CCC-SLP, Special School District of St. Louis County, Town & Country, Missouri Vocal cord dysfunction involves inappropriate vocal cord motion that produces partial airway obstruction. Patients may present with respiratory distress that is often mistakenly diagnosed as asthma. Exercise, psychological conditions, airborne irritants, rhinosinusitis, gastroesophageal reflux disease, or use of certain medications may trigger vocal cord dysfunction. The differential diagnosis includes asthma, angioedema, vocal cord tumors, and vocal cord paralysis. Pulmo- nary function testing with a flow-volume loop and flexible laryngoscopy are valuable diagnostic tests for confirming vocal cord dysfunction. Treatment of acute episodes includes reassurance, breathing instruction, and use of a helium and oxygen mixture (heliox). Long-term manage- ment strategies include treatment for symptom triggers and speech therapy. (Am Fam Physician. 2010;81(2):156-159, 160.

  • Vocal Cord Dysfunction: a Review Neha M
    Dunn et al. Asthma Research and Practice (2015) 1:9 DOI 10.1186/s40733-015-0009-z REVIEW Open Access Vocal cord dysfunction: a review Neha M. Dunn1*, Rohit K. Katial2 and Flavia C. L. Hoyte2 Abstract Vocal cord dysfunction (VCD) is a term that refers to inappropriate adduction of the vocal cords during inhalation and sometimes exhalation. It is a functional disorder that serves as an important mimicker of asthma. Vocal cord dysfunction can be difficult to treat as the condition is often underappreciated and misdiagnosed in clinical practice. Recognition of vocal cord dysfunction in patients with asthma-type symptoms is essential since missing this diagnosis can be a barrier to adequately treating patients with uncontrolled respiratory symptoms. Although symptoms often mimic asthma, the two conditions have certain distinct clinical features and demonstrate specific findings on diagnostic studies, which can serve to differentiate the two conditions. Moreover, management of vocal cord dysfunction should be directed at minimizing known triggers and initiating speech therapy, thereby minimizing use of unnecessary asthma medications. This review article describes key clinical features, important physical exam findings and commonly reported triggers in patients with vocal cord dysfunction. Additionally, this article discusses useful diagnostic studies to identify patients with vocal cord dysfunction and current management options for such patients.

  • Vocal Cord Dysfunction (VCD)
    Leaders In Allergy & Asthma Care For Over 40 Years Vocal Cord Dysfunction (VCD) Vocal cord dysfunction (VCD) is a disorder of the vocal cords (or vocal folds). When a patient experiences VCD, the vocal cords adduct (come together) during inspiration when they should abduct (spread apart). Smooth movement of air into and out of the chest is obstructed and it is harder to breathe. During VCD episodes patients feel anxious, helpless, or terrified. Patients typically feel as if they can’t breathe. Some patients feel faint. The exact cause of VCD remains unknown. Symptoms that commonly occur during VCD include: Wheezing (a whistling sound typically from the neck) Shortness of breath Hoarseness Audible breathing (stridor) Throat or chest tightness Triggers of VCD include: Exercise Coughing Acid reflux (GERD) Breathing cold air Breathing irritants (tobacco smoke, pollution, strong odors etc.) Stress (emotional and psychosocial issues) VCD verses Asthma VCD may mimic or coexist with asthma. Symptoms and triggers of VCD can overlap with those of asthma. Correct diagnosis is important since asthma medication will have little or no effect on symptoms caused by VCD and may even make symptoms worse. Patients who have VCD along with asthma will frequently find that their usual asthma therapy is no longer as effective at preventing breathing difficulties or that asthma "rescue medication" no longer works. Diagnosis Correct diagnosis is important. The diagnosis of VCD is made based on history, physical examination, and testing. Testing to evaluate asthma is important. Your doctor may recommend special testing to determine if you have asthma, VCD, or both.

  • Larynx (Vocal Cord Nodule)
    ATLAS OF HEAD AND NECK PATHOLOGY LARYNX LARYNX (VOCAL CORD NODULE) Vocal cord nodules are seen in men more than women and are attributed to misuse of the voice and heavy smoking. They are located on the true vocal cords at the junction of the anterior one third and the posterior two thirds of the cords. They are not neoplastic. Hyperkeratosis is common where the nodule meets or “kisses” a similar nodule on the opposite cord. Other nodules are made of hyalinized collagen which may be confused with amyloid. Many of these nodules are quite vascular and almost hemangiomatous. Tissues submitted to the pathologist as “vocal cord nodules” may vary considerably due to inaccuracy of clinical diagnosis. Some “nodules” undoubtedly would better be described clinically as polyps or even granulomas. Vocal cord nodule.

    K. J. Lee: Essential Otolaryngology and Head and Neck Surgery (IIIrd Ed) Chapter 15: The Larynx Embryology of the Larynx (see Chap. 11, pages 306-310) Anatomy Anatomy The larynx consists of a framework of cartilages, held in position by an intrinsic and extrinsic musculature, and lined by mucous membrane which is arranged in characteristic folds. The larynx is situated in front of the fourth, fifth, and sixth cervical vertebrae. The upper portion of the larynx, which is continuous with the pharynx above, is almost triangular in shape; the lower portion leading into trachea presents a circular appearance. Laryngeal Cartilages The laryngeal cartilages form the main framework of the larynx and consist of: 1. Thyroid cartilage (unpaired). 2. Cricoid cartilage (unpaired). 3. Epiglottis (unpaired). 4. Arytenoid cartilage (paired). 5. Corniculate cartilage (paired). 6. Cuneiform cartilage (paired). Thyroid Cartilage The thyroid cartilage (hyaline cartilage) is the largest and encloses the larynx anteriorly and laterally, thus shielding it from all but the most forceful blows. This cartilage is composed of two alae which meet anteriorly, dipping down from above to form the thyroid notch before meeting at the protuberance of the Adam's apple. Posteriorly, each wing has a superior cornu, extending upward about 2 cm, and a much shorter inferior cornu which articulates with the cricoid cartilage below. This is the only direct articulation of the thyroid cartilage, all other relationships with contiguous structures being maintained by muscles or ligaments. Cricoid Cartilage The cricoid cartilage (hyaline cartilage) lies directly below the thyroid cartilage. It is the strongest of the laryngeal cartilages, and is shaped like a signet ring.

  • A Study of Stroboscopic Parameters in Vocal Cord Pathologies
    Original Research Article A study of stroboscopic parameters in vocal cord pathologies Sheetal Shelke1, Nilam Sathe2, Hetal Marfatia3, Asmita Madhavi4* 1Assistant Professor, Department of ENT, MIMSR Medical College, Latur, INDIA. 2Associate Professor, 2Professor, 3Assistant Professor, Department of ENT, Seth G.S. Medical College, Mumbai, INDIA. Email: [email protected] Abstract Background: Speech is one of the unique qualities that sets man apart from all other living organism. Voice disorders isolate a person from the society but could also have deep impact on emotional and occupational aspect of life. Stroboscopy has evolved as the most practical and useful technique for the clinical evaluation of the visco-elastic properties of the phonatory mucosa. It provides useful, real-time information concerning the nature of vibration, an image to detect vocal pathology, and a permanent video record of the examination. Aim: To study the stroboscopic parameters in vocal cord pathologies. Material and Methods: A total of 30 cases (18-60 years) presented with complaints of change in voice and hoarseness of voice in Department of ENT, KEM Hospital Mumbai were examined. Stroboscopic examination was carried for these patients. All parameters of stroboscopy including symmetry, amplitude of vibration, mucosal wave, glottis closure and periodicity were observed in these patients. Results: All patients those had vocal cord cysts (2) and polyps (6) underwent microlaryngoscopic surgery showed symmetry of vocal cords in all patients (100%). Increased in amplitude was not observed in any patient. Vocal cord mucosal wave was normal in all patients with sulcus (2), vocal cord palsy (5), spasmodic dysphonia (1) and anterior commissure web (1).

  • Original Article Hoarseness of Voice
    Bangladesh J Otorhinolaryngol 2017; 23(1): 47-51 Original Article Hoarseness of Voice : An Etiological Study Salah Uddin Ahmmed1, AKM Asaduzzaman2, Mohammed Ahmed Ahsan3, Md Zakir Hossain2, Mohammad Ali Azad2, Mohammed Iftekharul Alam2 Abstract: Hoarseness of voice is one of the commonest symptom in otolaryngological practice and it indicates diseases ranging from totally benign condition to the most malignant condition. The aim of this study was to analyze clinical profile, to find out common etiological factors and association of common predisposing factors leading to hoarseness of voice. The study was carried out in the department of ENT, CMB, BAF Dhaka, from February 2014 to July 2016. A total of 130 patients having hoarseness of voice were selected coming to the OPD. All the patients then underwent a detailed history, ENT examinations and investigations to reach a diagnosis. Out of total 130 patients 76(58.47 %) were males and 54 (41.53) were females. Male predominance was observed with male female ratio of 1.49: 1. Common age group involved was 31- 40 years in 29 (20.7%) cases. Common etiology included chronic laryngitis in 37 (28.46%) cases, vocal nodules in 20 (15.38%), vocal cord polyp in 18 (13.84%), acute laryngitis in 10 (7.69%), vocal cord cyst in 9 (6.92%), hypothyroidism in 7 (5.38%) and Carcinoma larynx in 6 (4.61%) patients. Most of the etiopathological factors found in this study were treatable disease. So, early diagnosis can reduce the morbidity and mortality.
