Background and Objectives : Patients with so-called 'functional voice disorders' who have structurally normal larynges and demonstrate muscle misuse in the larynx, and those with several interacting causes including habitual muscle tension, are probably better defined as having a 'muscle misuse voice disorder'. The purpose of this study was to analyze the voice and effectiveness of voice therapy in patients with functional voice disorders and to provide a guide for the treatment of functional voice disorder. Materials and Method : The records of 35 patients, presenting with functional voice disorder and receiving voice therapy during October, 2001 to September, 2002, were reviewed. Prior to voice therapy, the stroboscopic examination of their larynx, aerodynamic and acoustic analysis was done. The results of voice therapy were compared according to the patient's subjective, perceptual evaluation of voice, and maximal phonation time. Results : Patient's subjective, perceptual evaluation, and maximal phonation time showed superior results after voice therapy. Conclusion : The result of this study indicates that voice therapy is an effective treatment method of patients with functional voice disorder, especially muscular tension dysphonia.

Subjective voice evaluation is necessary and important to assess the voice disorders in addition to objective voice evaluation. Subjective voice evaluation is divided into examiner and examinee subjective voice assessment. The examiner assessment represents perceptual judgment to the patient's voice such as GRBAS scale, Buffalo voice profile, consensus auditory perceptual evaluation of voice (CAPE- V) and so on. The examinee assessment consists of indirect method including voice handicap index (VHI), voice outcome survey (VOS), voice symptom scale (VoiSS), voice related quality of life (V-ROQL) and direct method which is called patient's self-subjective voice rating. This review article describes a general rule, advantages and pitfalls about GRBAS scale, VHI and patient's self-subjective voice rating which are presently most representative voice assessment tools.

Functional dysphonia (FD) is a disease entity which includes various voice disorders in the absence of structural or neurologic laryngeal pathology. Muscle tension dysphonia (MTD), psychogenic dysphonia are representative FD with completely different pathogenesis. Therefore there is no standard treatment modality for FD, the first step of treatment of FD is differentiating patient's voice symptoms from other organic voice disorders and other functional voice problems. MTD is a functional voice disorder caused by hyperfunction of intrinsic and extrinsic laryngeal musculature. Symptoms include increased vocal effort, roughness, fatigue and odynophonia. First line for MTD is indirect or direct voice therapy. Unfortunately, many patients with MTD improve with voice therapy alone. For these patients, various modalities tried; lidocaine application, surgical excision of the false vocal folds, and botulinum toxin injection, etc. Botulinum toxin injections are widely used in the field of otolaryngology, especially for spasmodic dysphonia. However, its use in FD or MTD has only been described in few case reports. The aim of this lecture is to evaluate the feasibility of botulinum toxin injection for FD, especially MTD.

The auditory-perceptual evaluation of speech-language pathologists (SLP) in patients with voice disorders is often regarded as a touchstone in the multi-dimensional voice evaluation procedures and provides important information not available in other assessment modalities. Therefore, it is necessary for the SLPs to conduct a comprehensive and in-depth evaluation of not only voice but also the overall speech production mechanism, and they often encounter various difficulties in the evaluation process. In addition, SLPs should strive to avoid bias during the evaluation process and to maintain a wide and constant spectrum of severity for each parameter of voice quality. Lastly, it is very important for the SLPs to perform a team approach by documenting and delivering important information pertaining to auditory-perceptual characteristics in an appropriate and efficient way through close communication with the laryngologists.
