Disfonía psicógena; características clínicas y biomecánicas

Zusammenfassung

Background and objectives: psychogenic dysphonia is a vocal behaviordisorder without organic alteration. It is usually related to an emotional picture. It has avariable clinical manifestation. The multidisciplinary approach is important duringtreatment and diagnosis. Biomechanical analysis is a non-invasive method that allowsobtaining, from a sound sample, a set of parameters that characterize the pattern of vocalproduction associated with the specific architecture of each vocal fold; the results showthat the alteration of the parameters serves as an indicator of pathology. The objective ofthis study is to describe the biomechanical pattern evidenced in a series of cases ofpatients diagnosed with psychogenic dysphonia. Material and methods: description of theclinical characteristics of the pathology. The findings evidenced by the biomechanicalanalysis of the voice with the App Online Lab® tool from Voice Clinical Systems® arepresented in a series of cases. Results: visual examination is not always able todifferentiate psychogenic dysphonia from other functional dysphonia. The vocalbiomechanical analysis can reveal alterations in several of its parameters (intensity,closing phase, tension, glottic force, gap and vocal efficiency, among others).Conclusions: The diagnosis is clinical; the importance of the anamnesis is highlighted;fluctuations through non-communicative voices. The biomechanical analysis of the voiceis a complementary tool that can provide important clues for its diagnosis.
