用声不当或过度致发声障碍的基础与临床研究 总被引:4,自引:1,他引:4
用声不当或过度可引起发声器官的病理改变,导致发声障碍。近年来随着社会发展,人类交往增多,尤其职业用声人群的增加,此类患者有逐年增多趋势。这类疾病常以慢性单纯性及肥厚性喉炎、声带小结、声带息肉为多见。据木下等(1978)报告,声带小结和声带息肉有过度用声史者占45%。国外有学者对898名教师进行嗓音调查分析,结果显示慢性喉炎(包括慢性单纯性喉炎、慢性肥厚性喉炎、声带小结、声带息肉)共270例,占30.07%。而国内类似的调查发现仅声带小结、声带息肉患者占所有被调查者的42.59%。可见用声不当或过度与声带慢性炎症的发生有密切关系。本文综述该类发声障碍的基础与临床研究进展,为探讨其病因、发病机理及进行有效治疗提供参考依据。 相似文献

This study investigates the relationship between glottal gap and vocal function in patients with glottic incompetence dysphonia. Twenty patients with vocal fold paralysis (VFP), 17 patients with vocal fold atrophy (VFA), and five patients with sulcus vocalis (SV) were examined. Glottal gap area at the most closed point of vibration was measured using digitized videostroboscopic images. Glottal gap area was correlated with acoustic and aerodynamic measures of vocal function. Patients with VFP had the largest glottal gaps and had significantly worse vocal function than did the patients with VFA or SV. Regardless of groups, however, where glottal gap size was similar, there was no difference in vocal function. Therefore vocal function was mainly influenced by glottal gap size, not by whether glottic incompetence was the result of VFP, VFA, or SV. 相似文献

Clinical applicability of the Ljubljana classification of epithelial hyperplastic laryngeal lesions 总被引:2,自引:0,他引:2
Gale N Zidar N Fischinger J Kambic V 《Clinical otolaryngology and allied sciences》2000,25(3):227-232
The diagnosis, prognosis, and choice of treatment of various laryngeal lesions depends almost entirely on the interpretation of changes in the covering epithelium. These abnormalities, referred to as epithelial hyperplastic laryngeal lesions, have been graded according to the Ljubljana classification into simple, abnormal and atypical (risky epithelium) hyperplasia and carcinoma in situ. The aim of this study was to evaluate the clinical applicability and prognostic value of this classification and to determine the incidence of malignant transformation. A retrospective clinical-pathological analysis was performed in a series of 4167 patients with 4574 biopsies, treated from 1979 to 1994. Simple (benign prickle cell) hyperplasia was the predominant grade in nodules, polyps, Reinke's oedema, granulomas, and papillomas, accounting for 37.6-68.6% of cases. In chronic laryngitis, abnormal (benign basal cell) hyperplasia was predominant with 43.9% of cases. Atypical ('risky') hyperplasia was observed almost exclusively in patients with chronic laryngitis (16.1%) and papillomas (10.1%), and only exceptionally in patients with vocal cord nodules (0.9%) and Reinke's oedema (0.3%). The percentage of malignant transformation in atypical hyperplasia was 11.6% (13/112 patients in 2-12 years), while in simple and abnormal hyperplasia, it was 0.3% (8/2920 patients in 1.5-11 years). The data support the concept of the Ljubljana classification dividing epithelial hyperplastic laryngeal lesions into benign (simple and abnormal hyperplasia), potentially malignant (atypical hyperplasia) lesions and carcinoma in situ. 相似文献

A breathing technique, or effective breath method is important for both singers and speakers for effective vocalization, and also useful for helping people with a voice problem. Here a diaphragm support breath pattern was used in voice therapy for patients with vocal nodules, recurrent laryngeal nerve paralysis, and incomplete glottal closure. Singing teachers use a technique, called the diaphragm breath support. This is called the yawning breath pattern (YBP) in our voice clinic and is used in teaching the patients with some kinds of voice disorder. In order to correct patients' breath pattern, an equipment system was designed to check their breath patterns conveniently in voice therapy practice. A respiratory kinematic sensor which connected to a TV monitor was attached to the patients' rib cage near the diaphragm, and by bio-feedback, patients could observe and adjust their breath pattern to the desired pattern during vocalization. In each of the 10 outpatient sessions, the patients performed for 20 to 30 min, and were instructed to practice at home for 3 or more times daily. The YBP method was applied to 91 patients, 17 males and 74 females, with ages ranging from 17 to 79 years. Of the 91 patients 41 had vocal nodules, 20 had recurrent laryngeal nerve paralysis and 30 had incomplete glottal closure associated with chronic laryngitis and sulcus vocalis. Most of the patients could master the YBP technique successfully. The higher the patients' ability to master the YBP was the better the results of both voice tests and subjective evaluation. The scientific background of the YBP method and its clinical effects in voice therapy was reviewed. 相似文献

OBJECTIVE: To ascertain effects of medialization thyroplasty on vocal fold vibration in glottic incompetence dysphonia. STUDY DESIGN: Quantitative videostroboscopic glottic measurements and vocal function study were perioperatively undertaken in 20 patients undergoing Isshiki's thyroplasty type I. METHODS: In digitized images, the glottal area, glottal width, posterior glottal width, and amplitude over an entire glottal cycle were measured and normalized by membranous vocal fold length. The ratio of closed phase to total phase of vibratory cycle was calculated from the data of the glottal area and the glottal width at the middle point of the membranous vocal fold. Well-accepted acoustic, aerodynamic, and perceptual measures analyzed vocal function. RESULTS: Glottal area and glottal width were reduced after surgery. While preoperative closure of glottal area was incomplete in all 20 patients, incomplete closure was obtained in 16 patients after surgery. In these 16 patients, closure of glottal width at the middle point of the membranous vocal fold was complete, whereas a posterior glottal gap remained in 14 patients. Closed phase over one cycle of glottal width waveform and amplitude of vocal fold vibration were increased after surgery. Glottal area, glottal width, posterior glottal width, and closed phase over one cycle of glottal width waveform correlated with vocal function measures. CONCLUSIONS: Thyroplasty type I reduces a glottal gap and increases closed phase over one cycle and amplitude of vocal fold vibration, although a posterior glottal gap remains. With the improved glottic vibration, thyroplasty type I provides more efficient phonation in patients with glottic incompetence dysphonia. 相似文献
