The purpose of the present study was to describe the effects ofacute laryngitis on some aerodynamic, acoustic, and perceptual measures. Eleven subjects with diagnosed acute laryngitis due to upper respiratory infection were recorded during a laryngitic episode and 1 week to 10 days after amelioration of the laryngitic condition. Fundamental frequency values, collapsed across the five vowels, were significantly reduced in the laryngitic compared with the normal speaking condition. The decrease in fundamental frequency associated with acute laryngitis suggests an increase in the mass of the vocal folds. In addition, aerodynamic values differed significantly for the laryngitic condition compared with the normal speaking condition, suggesting the presence of laryngeal hypofunction. Perceptual data indicated that speakers in the laryngitic condition were judged to have a hoarse voice when compared with the normal speaking condition. 相似文献

A retrospective review was conducted of 40 singers presenting with acute voice problems prior to performance. The purpose of this study was to determine the reasons for seeking emergent voice treatment, the types of acute voice disorders, and the performance outcome. The patients were assessed by age, singing style, years of experience, chief complaint, laryngovideostroboscopic findings, and treatment regimens. The outcomes were classified as full, restricted, or no performance. The majority of patients were classical singers. Laryngovideostroboscopy frequently revealed a pattern of early glottic contact at the mid-portion of the membranous vocal fold in patients with acute laryngitis. Experienced singers uniformly sought treatment many days before their performance compared with inexperienced singers who presented closer in time to performance. Six patients initially withheld information, which had a bearing on their acute management. The results of this study suggest that there is a need to accurately diagnose and treat the singer's emergent problem and educate singers regarding early evaluation of medical problems. With modern evaluation techniques and multi-modality treatment, 85% of the singers proceeded to full performance without negative sequelae. 相似文献

Acute and prolonged laryngitis commonly are diagnosed and treated by primary care physicians. These ailments come to the attention of the otolaryngologist when symptoms are prolonged despite treatment. Since the beginning of 1991, the senior authors (RTS, JRS) have recognized a clinical syndrome defined by prolonged hoarseness, prolonged laryngeal inflammation, and vocal fold ulceration. Patients are frequently young, nonsmokers, and nondrinkers who have had an upper respiratory infection prior to, or associated with, the onset of laryngeal symptomatology. Patients may be affected for up to 1 year despite aggressive medical therapy. This review of 14 patients highlights the features of this previously undescribed entity. 相似文献

The incidence of gastroesophageal reflux disease (GERD) in patients with laryngopharyngeal symptoms is greater than expect. A prospective study was performed to investigate the incidence of gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) in patients with laryngopharyngeal symptoms. Laryngologic evaluation with nasopharyngeal and laryngeal endoscopy and gastroenterologic evaluation with esophagogastroduodenoscopy including measurement of pH value were performed in 46 patients. Therapeutic intervention included general antireflux precautions and antireflux medication, and eradication of Helicobacter pylori in selected cases. Posterior laryngitis was present in 33 patients. GERD was present in 25 patients, hiatus hernia in 4 patients, H pylori-positive gastritis in 11 patients, and Barrett's metaplasia in 2 patients. Increasing evidence shows that GERD may cause laryngopharyngeal symptoms. Otherwise laryngopharyngeal symptoms can be predictors of GERD. Medical antireflux treatment is also effective for laryngopharyngeal symptoms. 相似文献

The acceptance of voice disorders by day care center teachers as an occupational disease is not an invariably established practice. This is due to the lack of reliable evidence of a higher risk for voice disorders in this profession. To find out the risk of voice disorders, an epidemiological study was conducted among day care center teachers (n = 262), using hospital nurses (n = 108) as a control group. Symptoms were charted by a questionnaire. In a clinical examination made by a laryngologist, the voice quality was assessed and the laryngeal status noted. Teachers at day care centers had significantly more voice disorders than did nurses. Vocal nodules and laryngitis findings appeared significantly more frequently among day care center teachers than among those in the control group. The results prove voice disorders to be more frequent among day care center teachers than among control group subjects, and also that the main cause for this may be a higher vocal loading among day care center teachers than among control group subjects. 相似文献

The particular problems faced by country and western singers have not often been studied. While making the words of the songs easily understood and creating a desired mood, country and western singers often strain their larynx. Usually, they do not benefit from the guidance of a vocal coach or have the social or economic background to seek early help or to know how to approach and enter the medical care delivery system. Even when they seek help, many speech pathologists, vocal coaches, and physicians are unfamiliar with their specific problems. Therapy for country and western singers depends on an accurate diagnosis and a clear understanding of their unique problems. 相似文献
