Relación entre movilidad velar e índice de ronquido en maniobra de fonema abierto.

Abstract

INTRODUCTION: We sought to identify the relationship between the response of velar mobility in the yawning maneuvers and the open vowel phoneme production maneuver with snoring. METHODS: 160 adult patients admitted to the OSAHS program were included in a Pneumology and Sleep clinic in the city of Medellín-Colombia, 87 patients were assessed by polygraph examination and 73 by polysomnography examination, with subsequent assessment of the Orofacial Myofunctional status (TMO). The statistical analysis for the qualitative variables was used absolute and percentage frequency and for the quantitative, means and standard deviations were used. Additionally, the distribution of the presence of obesity, velar and uvular mobility was generated for each of the two examinations (PSG and PLG) and a description of the snoring index (IR) was made for each of the variables of interest through medians and interquartile ranges; 95% confidence intervals were used for all estimates. RESULTS: The median IR for the PSG group is 86.5, and 41.7 for the PLG. In the PSG group, those subjects with normal velar ascent and without obesity showed the highest IRs (370.4 and 140.3, respectively), in the PLG group the males and obese patients showed the highest IRs (47, 4 and 41.7, respectively) The quantile regression model showed results of the subjects evaluated by PSG examination and those with reduced velar ascent as follows: (-317.7 95% CI -490.3 to -145.0, the veil does not ascend (-288.9 95% CI -481.6 to -96.1) and those who were not visualized by high lingual dorsum (-282.7 95% CI -537.6 to -27.7) had an association with IR, in the PLG group and in the total sample, no associations were reported. ANALYSIS AND DISCUSSION: There was an association between IR and reduced velar ascent as follows (-317.7 95% CI -490.3 to -145.0): less velar ascent, less snoring index in PSG; association between reduced velar ascent, the veil does not ascend (-288.9 95% CI -481.6 to -96.1) less velar ascent, less snoring index in PSG; association between IR and those who are not visualized due to high lingual dorsum (-282.7 95% CI -537.6 to -27.7); The less possibility of visualizing the soft palate from the upper lingual dorsum, the lower the snoring index in PSG; relationship between patients assessed by PSG with normal velar ascent and without obesity who showed the highest IR; relationship between results of obese male PLG-assessed patients with higher IR CONCLUSIONS: In order to respond to the events presented, a literature search was carried out, but this is scarce in relation to the pathophysiology of snoring as an isolated event.
