Functional Dysphonia
Conditions
Brief summary
Following a thyroidectomy, voice and swallowing alterations, which more frequently would appear to be caused by lesions of the laryngeal nerve, may occur. But, voice and swallowing changes can also occur in the absence of lesions of the inferior laryngeal nerve or the external branch of the superior laryngeal nerve, defining a condition called central compartment syndrome or functional post-thyroidectomy syndrome. It has been demonstrated that, in the presence of the aforementioned syndrome, the quality of the voice undergoes a deterioration immediately after thyroidectomy surgery with a lowering of pitch. The purpose of this study will be to verify the effects of early speech therapy, including pre-operative speech therapy counseling (during which the patient will be provided with indications to be implemented in the immediate post-operative period).
Interventions
BEHAVIORALPre-operative counselling
A preoperative speech therapy counseling will be carried out the day before the Total Thyroidectomy with the aim of informing patients about the possible conditions of the immediate post-operative period. Therefore, indications of vocal hygiene and hydration standards will be simultaneously administered, to be implemented from the first post-operative day. Patients will undergo phoniatric follow-up in the immediate post-operative period, at 7 days, 1 month and 3 months post-operatively. Patients who, at follow-up checks, should present the symptoms of functional post-thyroidectomy syndrome will undergo a cycle of post-operative speech therapy of 8 sessions.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Acoustic analysis (f0) | 3 months | Using the Multidimensional Voice Program, the Fundamental Frequency (F0, Hz) will be analyzed in the central 3 seconds of a sustained /a/. |
| Acoustic analysis (NHR) | 3 months | Using the Multidimensional Voice Program, the noise/harmonics ratio (NHR) will be analyzed in the central 3 seconds of a sustained /a/. |
| Acoustic analysis (Jitter%) | 3 months | Using the Multidimensional Voice Program, the Jitter (%) will be analyzed in the central 3 seconds of a sustained /a/. |
| Acoustic analysis (Shimmer%) | 3 months | Using the Multidimensional Voice Program, the Shimmer (%) will be analyzed in the central 3 seconds of a sustained /a/. |
| Voice Range Profile (Flow) | 3 months | The patient will be instructed in the production of a sustained /a/ from the lowest to the highest note, from minimum to maximum intensity. In this case, the Minimum frequency (Flow) will be analysed. |
| Voice Range Profile (Fhigh) | 3 months | The patient will be instructed in the production of a sustained /a/ from the lowest to the highest note, from minimum to maximum intensity. In this case, the Maximum frequency (Fhigh) will be analysed. |
| Voice function | 3 months | A questionnaire called Voice Impairment Score (VIS) will be used, created specifically to investigate the frequency of voice alterations. The VIS consists of 10 items and can vary from a minimum score of 0 (no vocal alteration) to a maximum of 40 (maximum voice disturbance). |
| Swallowing function | 3 months | A questionnaire called Swallowing Impariment Scores (SIS) will be used, created specifically to investigate the frequency of swallowing alterations. The SIS consists of 5 items and can vary from a minimum score of 0 (no vocal alteration) to a maximum of 20 (maximum swallowing disturbance). |
