Voix de patientes avec suspicion d’atteinte du nerf laryngé supérieur : rythme et perception

Abstract : After total thyroidectomy, the patient's voice complaint, excluding recurrent paralysis, is attributed to damage on the cricothyroid branch of the superior laryngeal nerve (SLN). However, it is still difficult to objectify. This study seeks to determine whether altered rhythmic parameters can be used as a diagnosis. It is supplemented by a perceptual evaluation and a questionnaire on the patient's feelings. 28 women with suspected injury on the cricothyroid branch of the SLN (CT-) were compared to 27 others without damage (CT+) after total thyroidectomy, compared to a control population (T). From speech tests, rhythmic parameters were measured, and a perceptual evaluation was carried out by an expert and a naive jury. Among the rhythmic parameters, the proportion of vocal intervals over the whole utterance (%V) is the only one to be altered in CT- compared to CT+ and T, witnessing a vocalic reduction. The mobilization of the vocal folds would be more complex for the CT-. This conclusion complements the findings already established, namely the reduction of the vocal range and vocal fatigue. Perceptual evaluation of the voice timbre from the GRBAS-I scale does not allow the voices of the 3 populations to be totally discriminated. However, the voice is perceived to be less modulated in CT- and CT+ compared to T. Self-assessment of patients CT- confirms the feeling of a severe vocal handicap for a few. Meeting the expectations of patients and voice professionals, this innovative study on the rhythm and perceptual evaluation of CT- has its whole interest.
