Posture and dysphonia associations in patients undergoing total thyroidectomy: stabilometric analysis

Abstract

The aim of this study is the analysis of postural changes of patients affected by vocal disorders post-thyroidectomy, in the absence of post-operative organ damage, through a stabilometry analysis, evaluating the effectiveness of a speech-language intensive treatment in phoniatric and postural quality recovery. 260 patients with vocal dysfunction after surgery without iatrogenic damage were enrolled. 130 patients were subject to post-surgical logopedic rehabilitative training (Group A); other 130 patients were not subject to any post-surgical treatment (Group B). For all patients, vocal and stabilometric parameters were evaluated before and after 2 days and 1 month from surgery. Vocal parameters evaluated were Voice Handicap Index-10, Maximum Phonation Time and objective evaluation of voice with Multidimensional Voice Program (MDVP). Stabilometric parameters evaluated were Sway area (mm2) and Sway velocity (mm/s) in firm surface and foam pad with eyes opened and closed. Regarding the stabilometric parameters, Group A obtained a statistically significant recovery of the correct posture statistically significant compared to Group B, after a month of speech therapy. Vocal parameters (VHI, MPT, MDVP) were statistically different between the two groups (p < 0.05), with a better improvement in Group A. Thanks to our study, we have shown that a logopedic rehabilitation therapy in patients with dysfunctional post-thyroidectomy dysphonia improves both the vocal and postural outcomes.
