Filter by:Singers are over-represented in phoniatric consultations; they present increased risk of developing voice disorders. The most common lesion found in singers is nodule. It comes from vocal straining characterized by the use of a pressed phonation mode, resulting in an increase subglottal pressure and a decrease flow rate. Voice therapy aims to restore a more relaxed phonation. There is a growing interest in semi-occluded vocal tract exercises with a straw in therapy; they have positive effects, particularly in terms of aerodynamic parameters such as subglottal pressure and oral airflow. After these exercises, subglottal pressure decreases and oral airflow increases. In other words, patient adopts a more relaxed phonation mode. Several studies have investigated the effect of these straw exercises on dysphonic patients i.e. on speaking voice; no study to date has explored the effect of these exercises on dysodic subjects i.e. on singing voice. The aim of this study is to evaluate the impact of straw exercises compared to open-mouth exercises on aerodynamic parameters in dysodic women singers with nodules.
Singers are over-represented in phoniatric consultation; they present increased risk of developing voice disorders. They represent a specific population among phoniatric patients (specific singing-voice complaints, increased sensitivity to voice). Singing-voice disorder is called dysodia in the same way as dysphonia, which refers to speaking-voice disorders. The diagnosis of dysodia is made after a laryngeal examination and a voice assessment to identify patient's speech and singing difficulties. Most studies on prevalence of voice disorders in singers come from the American continent. Very few descriptions of this population have been made in France. Voice assessment of dysodic singers includes aerodynamic voice measurements. The use of aerodynamic measurements for the diagnosis of voice pathologies is now widely demonstrated. These parameters include measurements of estimated subglottal pressure (ESGP), phonation threshold pressure (PTP) (minimum pressure to initiate a sound) and oral airflow (OAF). They depend on the level of training of singers and the type of vocal dysfunction. Aerodynamic behaviours of dysodic singers have not yet been described, although they can help to better identify the singer's vocal difficulties and could be essential parameters for targeting more precisely rehabilitation exercises proposed in voice therapy. This study aims to describe the characteristics of a French population of singers consulting in phoniatrics and their aerodynamic behaviours. Do the singers' aerodynamic parameters (pressure, flow) reflect the dysfunctions in singing voice? Based on results of the literature on speaking and singing non-pathological voice, the investigators hypothesize that during voice assessment, ESGP values will be increased and OAF ones will be decreased over the entire vocal range of the singer in case of voice pathology.
