Spastic dysphonia is a disorder of phonation which is characterized by a strained, creaking, and choked vocal attack, a tense and squeezed voice sound. Spastic dysphonia in a functional voice disorder can be classified into two types from the viewpoint of activities of the extrinsic and intrinsic laryngeal muscle groups. A functional voice disorder pertaining to abnormal activities of the intrinsic and extrinsic laryngeal muscles results in spastic dysphonia. The adductor spastic dysphonia may be due to abnormal actions of the intrinsic laryngeal muscles as such is relieved by sectioning of the recurrent nerve, while spastic dysphonia mainly dealing with the extrinsic laryngeal muscles is relieved by relaxation on monitoring an electromyographic feedback system. Within 3 months we encountered two patients whose extrinsic laryngeal muscles were hyperactive on phonation. A trial on injection of lidocaine into extrinsic laryngeal muscles made their muscles relax. So, biofeedback therapy of relaxation was began using a monitoring system of EMG burst regarding to hypertonicity of the extrinsic laryngeal muscles. Normal vocal abilities were recovered using a biotrainer as a monitoring device of electromyographic feedback.

The aim of this pilot research was to investigate acute voice and throat symptoms related to organic dust exposure among nine subjects with suspected occupational rhinitis or asthma. Subjective voice and throat symptoms were recorded before and after an occupational exposure test. In addition, the study included perceptual assessment of subjects' voice samples recorded before and after the exposure tests. The results showed a number of (statistically) significant voice and throat changes in symptoms based on subjects' own assessments. These symptoms included a hoarse, husky, or tense voice, requiring an extra effort when speaking and difficulty in starting phonation (P < 0.05). Other significant symptoms included feeling of shortness of breath or the need to gasp for air and feeling that the voice is weak or that it does not resonate (P < 0.01). Such changes were not, however, detected by voice clinicians in the listening test of subjects' voice samples recorded before and after the exposure. These results suggest that the larynx reacts to organic dust with symptoms that are felt by the patient rather than heard by the voice clinician. The voice disorder in such cases is a diagnosis based on symptoms expressed by subjects.
