Evaluation of some velar functions before and after surgical treatment of snoring.
The aim of this prospective study was to evaluate velar function before and after uvulopalatopharyngoplasty for isolated snoring and for sleep apnoea. It is based on the analysis of oral and nasal airflow during phonation by an EVA workstation of 24 patients before and after the surgical intervention. The results show (1) quantitative and qualitative airflow abnormalities before the operation, (2) an increase in the percentage of nasal airflow flow after the operation, and (3) a change in the airflow sequence, which is improved after the surgical procedure. In conclusion, this work confirms a modification of velar function after uvulopalatopharyngoplasty and raises the problem of contra-indications to this intervention.
