Objective This guideline provides evidence-based recommendations on treating patients who present with dysphonia, which is characterized by altered vocal quality, pitch, loudness, or effort that impairs communication and/or quality of life. Dysphonia affects nearly one-third the population at some point in its applies to all age groups evaluated a setting where dysphonia would be identified managed. It intended for clinicians are likely diagnose and treat dysphonia. Purpose The primary...
Endoscopic treatment of laryngotracheal stenosis by airway dilation, despite short-term improvement, is often associated with long-term relapse. Mitomycin-C (MMC) inhibits fibroblast proliferation and synthesis extracellular matrix proteins, thereby modulates wound healing scarring. MMC application at the time endoscopic dilation laser surgery has been suggested to improve outcomes, but this not studied in a rigorous manner. This study examines hypothesis that two topical applications given...
Surgical treatment comparisons in rare diseases are difficult secondary to the geographic distribution of patients. Fortunately, emerging technologies offer promise reduce these barriers for research.To prospectively compare outcomes 3 most common surgical approaches idiopathic subglottic stenosis (iSGS), a airway disease.In this international, prospective, 3-year multicenter cohort study, 810 patients with untreated, newly diagnosed, or previously treated iSGS were enrolled after undergoing...
Objectives Presbylaryngis, or aging of the larynx, can adversely affect vocal function and quality life in elderly. This preliminary investigation examined effects exercises, a physiologic voice therapy approach, as primary treatment for presbylaryngis. Methods Nine consecutive elderly patients with presbylaryngis (2 female, 7 male) underwent 6-week course employing exercises. Pretherapy-versus-posttherapy comparisons were made self-ratings handicap phonatory effort level, well...
Objectives/Hypothesis Idiopathic subglottic stenosis (iSGS) is a rare and potentially life‐threatening disease marked by recurrent progressive airway obstruction frequently requiring repeated surgery to stabilize the airway. Unknown etiology low prevalence have limited ability characterize natural history of iSGS resulted in variability surgical management. It uncertain how this variation relates clinical outcomes. Study Design Medical record abstraction. Methods Utilizing an international,...
<b>Objective: </b> To compare electromyographic (EMG) amplitudes of the thyroarytenoid (TA) muscle in young and older individuals with idiopathic PD (IPD) under conditions known vocal loudness (sound pressure level). <b>Background: Voice disorders frequently accompany aging IPD, but it is unclear how laryngeal physiology affected by these processes changes activity result characteristic voice. <b>Methods: Absolute relative (to maximum) EMG TA were compared during speech nonspeech tasks....
Abstract Laryngotracheal reconstruction (LTR) comprises five stages: 1, characterization of the stenosis; 2, expansion lumen; 3, stabilization enlarged lumen framework; 4, healing surgical site; and 5, decannulation. Single‐stage LTR (SS‐LTR) combines compresses stages 3 through 5 (stabilization, healing, decannulation) into a brief period postoperative intubation. At Children's Hospital Medical Center in Cincinnati, Ohio, from January 1987 to December 1993,116 reconstructive procedures were...
Abstract Objectives/Hypothesis: Children with cleft deformities have the tendency for multilevel airway obstruction. The incidence of sleep disordered breathing (SDB) in this population has not been well studied. This study attempts to describe high and results intervention. Study Design: A three‐year retrospective chart review by a tertiary craniofacial team. Methods: symptoms polysomnographic data were reviewed analyzed using descriptive statistics multivariate analysis. Results: Of 539...
Background Recurrent Respiratory Papillomatosis (RRP) is a rare disease characterized by the growth of papillomas in airway and especially larynx. The clinical course highly variable among individuals there poor understanding factors that drive an aggressive vs indolent course. Methods A convenience cohort 339 affected subjects with positive for only HPV6 or HPV11 data available 1 year more, from large multicenter international study were included. Exploratory analysis was conducted followed...
A roadblock for research on adductor spasmodic dysphonia (ADSD), abductor SD (ABSD), voice tremor (VT), and muscular tension (MTD) is the lack of criteria selecting patients with these disorders.
This study examined the effect of aging on respiratory and laryngeal mechanisms involved in vocal loudness control. Simultaneous measures subglottal pressure electromyographic (EMG) activity from thyroarytenoid (TA), lateral cricoarytenoid (LCA), cricothyroid (CT) muscles were investigated young old individuals while they attempted to phonate at three levels, "soft," "comfortable," "loud." Voice sound level (SPL) fundamental frequency (F 0 ) also obtained. Across conditions, levels similar...
Adductor spasmodic dysphonia (ADSD) has been characterized as a "task specific" laryngeal dystonia, meaning that the severity of varies depending on demands vocal task. Voice produced in connected speech compared with sustained vowels is said to provoke more frequent and severe spasms. This study examined diagnostic value specificity" marker ADSD its potential differentiate from muscle tension (MTD), functional voice disorder can often masquerade ADSD.Case-control study.Five listeners,...
Osteoma is the most common benign tumor of nose and paranasal sinuses, frontal sinus its frequent location. This may be discovered incidentally on radiographs or enlarge to produce symptoms and, rarely, complications referable location near orbit anterior cranial vault. A series 22 cases osteoma treated at UCLA Center for Health Sciences reviewed. The presenting this tumor, patient examination, radiographic evaluation, diagnosis, indications surgical nonsurgical management are discussed....
To determine the incidence of left vocal fold paralysis (LVFP) in premature infants who undergo patent ductus arteriosus (PDA) ligation.Prospective cohort.The study was carried out newborn intensive care unit (NICU) a tertiary academic medical center. Eighty-six newborns underwent ligation PDA were examined postextubation with fiberoptic laryngoscopy to assess mobility, regardless laryngeal symptom status.Fourteen (16%) had LVFP. All <28 weeks postmenstrual age (PMA) at birth and <1,250 g...
Abstract Objectives: The purpose of this study was to measure and compare biomechanical properties commonly used vocal fold injectates Cymetra, Radiesse, Restylane, Hylaform, one investigational injectate, Carbylan‐GSX 5%, determine suitability for mucosal injection. Study Design: Rheologic investigation. Methods: Oscillatory shear stress applied five samples each injectate using a parallel plate controlled rheometer. Shear stress, strain, strain rate associated with the oscillatory...
Outcomes of laryngeal reinnervation with ansa-cervicalis for unilateral vocal fold paralysis (UVFP) may be influenced by age the patient and time interval between nerve injury reinnervation, suggesting less favorable outcomes in older patients greater than 2-year after injury. This study examines these issues pediatric population.Review prospectively collected data set 35 children adolescents (1-21 years) that underwent ansa-recurrent (RLN) UVFP.The from RLN to averaged 5.0 years (range,...
<h3>Importance</h3> Bilateral vocal fold paralysis (BVFP) in pediatric patients is a challenging entity with multiple causes. Traditional approaches to managing BVFP include tracheostomy, arytenoidectomy, suture lateralization, cordotomy, and posterior cricoid enlargement. These interventions are used create stable airway but risk compromising voice quality. <h3>Objectives</h3> To assess the use of bilateral selective laryngeal reinnervation (SLR) surgery manage restore dynamic function...
Objectives/Hypothesis The purpose of this study is to develop consensus on key points that would support the use systemic bevacizumab for treatment recurrent respiratory papillomatosis (RRP), and provide preliminary guidance surrounding modality. Study Design Delphi method‐based survey series. Methods A multidisciplinary, multi‐institutional panel physicians with experience using RRP was established. method used identify obtain characteristics associated across five domains: 1) patient...
