Vocal cord dysfunction (VCD) is an uncommon condition which often mimics asthma in presentation and severity. We present nine- and 11-year-old female siblings with vocal cord dysfunction, which is a dysfunction of the larynx involving unintentional paradoxical adduction of the vocal cords during inspiration. We evaluated the use of exercise testing in conjunction with pulmonary function testing in suspected vocal cord dysfunction. Although normal pulmonology function tests were elicited with the patient at rest, exercise testing revealed blunting of the expiratory loop with attenuation of the inspiratory loop unique to VCD. The child underwent video laryngoscopy in the specialised voice clinic, which confirmed vocal cord dysfunction. Exercise testing is a rapid and noninvasive means of diagnosing vocal cord dysfunction in a small subset of patients, but video laryngoscopy, with training manoeuvres to elicit paradoxical vocal cord movements in VCD, remains the gold standard of diagnosis of VCD ...

Paradoxical vocal cord motion disorder (PVCM), also called vocal cord dysfunction, is an important differential diagnosis for asthma. The disorder is often misdiagnosed as asthma leading to unnecessary drug use, very high medical utilisation and occasionally tracheal intubation or tracheostomy. Laryngoscopy is the gold standard for diagnosis of PVCM. Speech therapy and psychotherapy are considered the cornerstone of management of this disorder. The aim of this article is to increase the awareness of PVCM among doctors, highlighting the main characteristics that distinguish it from asthma and discuss the recent medical achievements and the possible future perspectives related to this disorder.. ...

The use of the s/z ratio as a clinical indicator of laryngeal pathology was investigated with 28 dysphonic subjects with laryngeal pathology (nodules or polyps), 36 dysphonic subjects without laryngeal pathology, and 86 normal-speaking subjects. While no statistical difference was found between the three groups in their ability to sustain /s/, the subjects with laryngeal pathology had significantly lower duration times for /z/ than subjects in the other two groups. The computed s/z ratios were significantly higher for the dysphonic subjects with laryngeal pathology; subjects with functional dysphonia free of laryngeal pathology demonstrated the same s/z ratios (approximately 1.0) as the normal-speaking control subjects. The dysphonic subjects with laryngeal pathology produced s/z ratios in excess of 1.4 ninety-five percent of the time. It appeared from these data that when an additive mass developed along the glottal margin, vocal fold approximation was less efficient. This decrement in ...

Many individuals seek my assistance for difficulty with paradoxical vocal fold motion, most commonly referred to as vocal cord dysfunction. This problem has been referred to by many names including inducible laryngeal obstruction. While many view this as a voice disorder, I believe it is a disorder of breathing and must be treated with knowledge of the entire respiratory system. Often misdiagnosed as asthma, common symptoms include shortness of breath, throat and or chest tightness and inability to take an adequate breath. Difficulty can occur in response to exercise, allergies, fumes, stress or for no apparent reason. Some individuals also struggle with habit cough and throat clearing. ...

Answer 4.1.1 The correct answer is E. Vocal cord dysfunction (VCD) is one of the most common asthma mimics. Patients with VCD present with hoarseness, coughing, dyspnea, and loud inspiratory wheezing/stridor, along with other symptoms mentioned above. Pulmonary function testing indicates airway obstruction due to an extrathoracic component. It appears that paradoxical inspiratory vocal cord adduction causes airflow restriction at the level of the larynx, resulting in a flattened inspiratory loop on flow-volume diagram. VCD presents a diagnostic challenge, and often leads to unnecessary treatment of asthma. In this patient, a β2-agonist was ineffective, even though she displays symptoms with exertion. This argues against answer A. The distinction between VCD and asthma may be less clear in other patients, since the two disorders sometimes coexist. The clinical history does not support the diagnoses of gastroesophageal reflux disease, musculoskeletal chest pain, or hyperventilation. ...

The ability to provide absolute calibrated measurement of the laryngeal structures during phonation is of paramount importance to voice science and clinical practice. Calibrated three-dimensional measurement could provide essential information for modeling purposes, for studying the developmental aspects of vocal fold vibration, for refining functional voice assessment and treatment outcomes evaluation, and for more accurate staging and grading of laryngeal disease. Recently, a laser-calibrated transnasal fiberoptic endoscope compatible with high-speed videoendoscopy (HSV) and capable of providing three-dimensional measurements was developed. The optical principle employed is to project a grid of 7 × 7 green laser points across the field of view (FOV) at an angle relative to the imaging axis, such that (after calibration) the position of each laser point within the FOV encodes the vertical distance from the tip of the endoscope to the laryngeal tissues. The purpose of this study was to develop ...

Jensens 18-hour procedure was followed by two months of rehabilitation. Her newly restored voice, while sounding hoarse at times, has improved significantly since the transplant as her nerves regenerate and she learns again how to speak. While the donor organ came from an accident victim, Jensens voice is her own and not that of the female donor. The transplant has allowed Jensen to smell and taste for the first time in years. She is in the process of relearning to swallow and hopes to soon be able to eat and drink normally again.. Gregory Farwell led a surgical team that included Peter Belafsky and Quang Luu (UC Davis Health System), Paolo Macchiarini (Karolinska Institutet, Sweden and UCL Ear Institute) and Professor Birchall. The entire transplantation involved nearly two dozen doctors, nurses, technicians, transplant coordinators and other medical personnel.. Professor Birchall said: Despite decades of effort, patients with advanced laryngeal disease or injury have faced reconstructive ...

Her symptoms began at home earlier that day and were not improved by bronchodilators. On arrival to the ED, she was lethargic in severe respiratory distress with laboring accessory muscle use. She had only an allergy to latex. Outpatient medications included albuterol inhaler, fluticasone/salmeterol inhaler, inhaled budesonide, furosemide, and warfarin for empiric treatment of an unidentified hypercoaguable disorder. She reported having a 15 pack year smoking history including marijuana and cocaine use up to several days prior to admission, but she denied any prior alcohol or intravenous (IV) drug abuse.

A 29-year-old medical resident in family practice, diagnosed with paradoxical vocal fold motion (PVFM) at 14 years of age and subsequently with asthma and gastroesophageal reflux disease, was referred to our clinic with PVFM recurrence following five symptom-free years. Her recurrence coincided with medical school graduation and the beginning of residency. Patient presented with inhalation phonation on every inhale during resting breathing and at natural pauses while speaking. After initial diagnosis, the patient had received behavioral therapy and medical evaluation and treatment, including heliox therapy, two supraglottoplasties, neurology evaluation (negative), Botox® therapy (unsuccessful) and asthma and reflux management.. Treatment consisted of 17 hours of direct treatment with three SLPs over two and a half days. Goals included elimination of inspiratory noise, achievement of carryover and generalization, and return to regular physical exercise. Treatment included training of the nasal ...

Standardized tests that assess functional performance for upper extremity (UE) strength and power are lacking. A functional performance test is an important tool in identifying strength, power, injury predisposition risk and readiness for return to activity following injury. The seated shot put test (SSPT) is a test of unilateral UE strength and power. The primary purpose of the present study is to determine normative test scores for the SSPT for a healthy high school aged population. A secondary purpose is to determine if any relationships exist between scores on the SSPT and arm length, body weight, sex and age. A sample of convenience testing only those within the high school population without UE pathology will be utilized. Participants with written consent from an adult were allowed to participate in the study. All the participants were instructed on how to properly throw the 2 kg ball. Participants were given four warm-up throws before official distance thrown was recorded. An average of ...

Aphasia: Speech-language therapy (SLT) to maximize communication skills through verbalizations or compensatory means (eg, communication boards, augmentative communication) is standard practice. Utilization of melodic intonation to sing words may be useful. Review of literature tends to support effectiveness of SLT with more intensive therapy as possibly more effective than conventional SLT. Pharmacological interventions with catecholiminergic, dopaminergic, and acetylcholinergic agonists as well as piracetam and memantine may be effective although evidence is inconclusive.. Dysarthria: Management focuses on maximizing strength and coordination of oromotor musculature. Behavioral approaches are used to optimize vocal cord adduction, improve posture, enhance breath support, improve strength and coordination of muscles involved in speech and improve prosody. Instrumental approaches used to improve speech include biofeedback and timers or pacers to control rate. Invasive procedures such as ...

Vocal cord dysfunction (aka, paradoxical vocal cord motion, VCD, non-organic wheezing, etc) is a general term used to describe a situation when the vocal cords come together (or ADduct) when taking a breath in when normally they should go apart (or ABduct). The key thing to remember is that everything from the nose down into the lungs generally appears totally normal anatomically speaking; however, the voicebox is functionally abnormal.

Vocal cord dysfunction (VCD), also commonly known as paradoxical vocal fold motion, can be characterized as an abnormal adduction of the vocal cords during the respiratory cycle (especially during the inspiratory phase) that produces airflow obstruction at the level of the larynx. VCD frequently mimics persistent asthma and is often treated...

Vocal cord dysfunction is the uncontrolled closing of the vocal cords when you breathe in. The symptoms can seem to be the same as those of asthma and may occur alone or along with asthma. If you have asthma and vocal cord dysfunction, it may be difficult for you to tell the difference between symptoms of the two conditions.. Sometimes vocal cord dysfunction happens quickly and may require a trip to the emergency room. The condition occurs in both men and women but may be more common in women who are high achievers.. Vocal cord dysfunction is often caused by postnasal drainage or gastroesophageal reflux disease (GERD) and improves with treatment of these conditions.. The following factors may help your health professional evaluate vocal cord dysfunction, especially in people who do not have asthma. The person:. ...

Hoarseness (dysphonia) is defined as an altered voice due to a laryngeal disorder.2 It is an important symptom of laryngeal disease presenting in general practice, and ranges from the very common, trivial, self-limiting condition of viral upper respiratory tract infection to a life-threatening disorder (see Table 57.1). It may be of sudden presentation lasting only a few days or develop gradually and persist for weeks or months. The cut-off point between acute and chronic hoarseness is three weeks duration, by which time most self-limiting conditions have resolved. Hoarseness pertains to harsh, raspy, gravelly or rough tones of voice rather than pitch or volume. Rarely, hoarseness can be a functional or deliberate symptom referred to as hysterical aphonia.3 In this condition, patients purposely hold the cords apart while speaking. ...

Your doctor may need to do two tests. One is a pulmonary function test to see how well your lungs are working. For this test, you blow forcefully into a machine that measures the speed and amount of air moving in and out of your lungs. This test is useful in telling the difference between vocal cord dysfunction and asthma.. The second test is flexible laryngoscopy (lar-in-GOS-coh-pee). Your doctor will pass a small, flexible tube through your nose to look at your vocal cords while you breathe. This test will help your doctor know if your vocal cords arent working right. ...

It is estimated that up to 50% of patients with voice disorders and 4-10% of patients seen in otolaryngology practice experience laryngopharyngeal reflux (LPR). LPR has been implicated in the pathogenesis of numerous laryngeal disorders, including subglottic stenosis, laryngeal carcinoma, laryngeal contact ulcers, laryngospasm, and vocal cord nodules. In the pediatric population, it has been associated with asthma, sinusitis, and otitis media. Common symptoms include chronic and intermittent hoarseness, vocal fatigue, globus pharyngeus, cough, postnasal drip, chronic throat clearing, and dysphagia.. Like gastroesophageal reflux disease (GERD), the etiology of LPR is linked to esophageal sphincter dysfunction. In GERD, the lower esophageal sphincter (LES) is involved, whereas in LPR, the pathology results from upper esophageal sphincter (UES) dysfunction. However, diagnosis of LPR is more challenging than that of GERD. The classic reflux-like symptoms of heartburn and regurgitation are often ...

This course details the continuum of hyperfunctional laryngeal symptoms spanning from throat clearing, chronic cough, muscle tension dysphonia to paradoxical vocal fold movement. Common etiologies are reviewed with interviewing strategies to determine what role behavioral therapy may have once irritants such as reflux, allergies and post-nasal drip are well controlled by the physician team. Cough suppression, muscle tension dysphonia remediation and vocal fold abduction for paradoxical vocal fold movement are discussed extensively. The lecture ends with audio samples of actual patients and 5 case studies.. ...

Bulatovic R, Taneja R. In Response to Videolaryngoscopy as a new standard of care. Zaouter C, Calderon J, Hemmerling TM. Br J Anaesth. 2015. 114(2):181-183.. Dear sir,. We read with interest Dr. Zauters editorial on the evolving role of videolaryngoscopy in anesthestic care (1). Overall we do agree with the authors that videolaryngoscopes will and should be available freely in the foreseeable future. As anesthetists working in a teaching hospital, we already note that residents often choose these as their first-choice for laryngoscopy in anticipated difficult intubations.. However, with increasing availability of new technology such as this, we must acknowledge that trainees will progressively lose their skills with conventional laryngoscopy. This may have safety implications for patients needing anaesthesia in remote locations where videolaryngoscopy may not be the norm. Hence, our younger colleagues having to provide anaesthetic services in such settings may find themselves underprepared or ...

Stridor is a sign of upper airway obstruction. In children, laryngomalacia is the most common cause of chronic stridor, while croup is the most common cause of acute stridor. Generally, an inspiratory stridor suggests airway obstruction above the glottis while an expiratory stridor is indicative of obstruction in the lower trachea. A biphasic stridor suggests a glottic or subglottic lesion. Laryngeal lesions often result in voice changes. A child with extrinsic airway obstruction usually hyperextends the neck. The airway should be established immediately in children with severe respiratory distress. Treatment of stridor should be directed at the underlying cause.

Laryngocele is an abnormal dilatation of the laryngeal saccule filled with air. It may extend through the thyrohyoid membrane or into the airway. According to its relation to the thyrohyoid membrane, it has been classified as internal, external, or combined laryngocele. Symptoms are related to the size of the laryngocele. It may cause cough, hoarseness, stridor, sore throat and may present as a swelling on the neck. In many cases, it is asymptomatic. Laryngocele is a rare cause of infant and pediatric airway obstruction. Treatment options are endoscopic excision or marsupialization, and excision through a lateral thyrotomy or the thyrohyoid membrane approach. In this study, a pediatric case with an internal laryngocele was presented as a rare congenital laryngeal pathology. Literature was reviewed and characteristics of the disease were discussed. ...

Dear Dr. Cooper:. I have just celebrated my 85th birthday and as I sat around discussing the past with some of my friends, I was astounded at the number of people that have had a profound affect on my life, both good and bad. You, sir are one of the good ones. In all of the intervening years, I have never spoken to you, and thanked you enough for what you have done for me.. Let me recall my history with you. After visiting three eye, ear, and nose specialists, they all agreed on two things, that I have a contact ulcer of the vocal cords and that surgery was the only way out. No guarantee that it wouldnt return, but that was the way to go.. Then my doctor came up with another specialist, a Dr. Rubin in Beverly Hills. I went to see him, in desperation. He confirmed the diagnosis of the other specialists and said the surgery is the only solution the medical profession has for cases like mine; however, I can recommend a speech therapist that has had a measure of success treating contact ulcers of ...

Laryngomalacia is a congenital softening of the tissues of the larynx above the vocal cords and is the most common cause of noisy breathing in infancy.

Laryngoceles are uncommon, with an estimated incidence of 1 per 2.5 million people per year.5 Laryngoceles are unilateral 85% of the time, so bilateral laryngoceles are an especially rare occurrence.1 There is a strong male preponderance, with rates in men 5-7 times greater than rates in women.. Laryngoceles are classified as internal, external, or mixed. Internal laryngoceles stay within the confines of the thyrohyoid membrane, while external laryngoceles extend beyond the cartilaginous boundaries of the larynx and maintain only a thin connection to their site of origin. Combined or mixed laryngoceles have substantial components both inside and outside the larynx.. The term laryngocele is generally used if the mass is air-filled or has an air-fluid level demonstrating an open communication with the laryngeal lumen. The term saccular cyst is used by some authors to refer to masses that are completely filled with fluid or mucous and thus presumably lack such a communication. Other authors use ...
