AB Introduction: The aim of our work was to determine if the corrected neck perimeter (CNP) is useful in the OSAS severity prediction.Methods: Descriptive study in which we have included 337 patients sent to the sleep unit by OSAS's clinical suspicion, from January 2007-2011 whom a polisomnografy was realized. We calculated the CNP according to Flemong's formula, which adds 3cm to the measured neck perimeter if the individual is a snorer, other 3cm if they have episodes of choke or gasp most nights and 4cm if they are hypertense. There have not been included in this study the patients in whom we couldn't calculate the formula. We have considered 3 degrees of severity: 1 if the CNP is <43, 2 if it is between 43 and 48, and 3 if it is >48 cm. We consider a mild OSAS if the IAH is 5-15, moderate if it is between 15-30, and severe if IAH>30.Results: The middle age of our patients was 50y (16-80); 78% males. The patient's percentage with different degrees of OSAS's severity according to his CNP is expressed in the table.View this table:IAH's average was 24 in the group with CNP <43 cm, in the group 43-48 was 29, and in the >48, it was 42, being statistically significant difference (p<0,0001), when we use Anova one factor and proportion's contrast (squareXi).Conclusions: The CNP is significantly correlated by the OSAS severity. By contrast in others studies, in our environment, the IAH> 5 probability post test, is 72%, when the CNP is > 43, and doesn't predict severity. The IAH> 5 probability post test is 96% if the CPN is> 48 and predicts OSAS severity.
