Functional dysphonia-a voice disturbance in the absence of structural or neurologic laryngeal pathology-is an enigmatic and controversial voice disorder that is frequently encountered in multidisciplinary voice clinics. Poorly regulated activity of the intrinsic and extrinsic laryngeal muscles is cited as the proximal cause of functional dysphonia, but the origin of this dyregulated laryngeal muscle activity has not been fully elucidated. Several causes have been cited as contributing to this imbalanced muscle tension; however, recent research evidence points to specific personality traits as important contributors to its development and maintenance. Voice therapy by an experienced speech-language pathologist remains an effective short-term treatment for functional dysphonia in the majority of cases, but less is known regarding the long-term fate of such intervention. Further research is needed to better understand the pathogenesis of functional dysphonia, and factors contributing to its successful management.
功能性发声障碍——一种在无结构性或神经性喉部病变情况下出现的嗓音障碍——是一种在多学科嗓音诊所中经常遇到的神秘且有争议的嗓音疾病。喉内肌和喉外肌活动调节不良被认为是功能性发声障碍的近端原因，但这种发声肌肉活动失调的起源尚未完全阐明。有几种原因被认为导致了这种肌肉张力失衡；然而，最近的研究证据指出特定的人格特质是其发展和维持的重要因素。在大多数情况下，由经验丰富的言语病理学家进行的嗓音治疗仍然是功能性发声障碍有效的短期治疗方法，但对于这种干预的长期效果了解较少。需要进一步研究以更好地理解功能性发声障碍的发病机制以及有助于成功治疗的因素。
