CONTEXT Laryngopharyngeal reflux (LPR) is a major cause of laryngeal inflammation and presents with a constellation of symptoms different from classic gastroesophageal reflux disease. OBJECTIVE To provide a practical approach to evaluating and managing cases of LPR. EVIDENCE ACQUISITION The PubMed database and the Ovid Database of Systematic Reviews(More)
The term sulcus vocalis has been applied to a spectrum of disorders ranging from minor vocal fold indentations to destructive lesions causing severe dysphonia. To clarify the pathophysiology and to develop a more rational approach to treatment, we report a series of sulcus patients including 20 surgical cases. Clinical and histopathologic analysis produced(More)
Manual circumlaryngeal therapy (manual laryngeal musculoskeletal tension reduction) was used to treat 25 consecutive functional dysphonia patients. Pre- and post-treatment audio recordings of connected speech and sustained vowel samples were submitted to auditory-perceptual and acoustical analysis to assess the immediate and long-term effects of a single(More)
A case-control study was conducted to investigate the risks of male and female oral, oropharyngeal, and hypopharyngeal cancer associated with poor oral health, mouthwash use, occupation, histories of tobacco and alcohol use, and other factors. Data were collected from all newly diagnosed patients entered into the Wisconsin Head and Neck Cancer Network over(More)
Glottic insufficiency has been successfully managed by Teflon augmentation of paretic vocal cords over the past two decades. Collagen fulfills the criteria for a suitable bioimplant and is an attractive alternative as it is a normal constituent of the extracellular protein matrix. This study explores the use of modified bovine collagen injected into the(More)
OBJECTIVE To examine the expressions of fibronectin and other adhesion molecules on the scarred vocal folds in a short- and long-term animal model. STUDY DESIGN Animal model. METHODS Six beagles' vocal folds were stripped unilaterally and left untreated. After wounding the vocal folds were harvested from three dogs at 2 months and three dogs at 6(More)
Scarring of the vocal folds can occur as the result of blunt laryngeal trauma or, more commonly, as the result of surgical, iatrogenic injury after excision or removal of vocal fold lesions. The scarring results in replacement of healthy tissue by fibrous tissue and can irrevocably alter vocal fold function and lead to a decreased or absent vocal fold(More)
Vocal fold scarring remains a therapeutic challenge. Hepatocyte growth factor (HGF) has strong antifibrotic activity and has proved to have therapeutic potential in restoration of scar tissues such as liver cirrhosis and lung fibrosis. The present study aimed to clarify the effects of HGF injection into scarred vocal folds in a canine model. Canine vocal(More)
Excessive activity of the extralaryngeal muscles affects laryngeal function and contributes to a spectrum of interrelated symptoms and syndromes including muscle tension dysphonia and spasmodic dysphonia. Recognition of the role of extralaryngeal tension is helpful in ensuring proper diagnosis and selection of appropriate treatment. This report demonstrates(More)
BACKGROUND/OBJECTIVES When the lamina propria of the vocal fold is replaced by fibrosis after wound healing, it is difficult to restore an appropriate viscoelasticity of the vocal fold. To treat fibrotic scarring, material that reduces collagen deposition and increases soft amorphous substances, such as hyaluronic acid, is required. The potential use of(More)
