Oropharyngeal Dimensions in Adults: Effect of Ethnicity, Gender, and Sleep Apnea

Journal of Clinical Sleep Medicine, 2005

Conclusion: “We concluded that (1) acoustic pharyngometry identifies differences in upper airway characteristics based on gender, ethnicity, and SDB status and (2) novel parameters can assist in quantifying these pharyngeal phenotypes. The novel parameters can potentially facilitate quantitative, as an adjunct to qualitative, comparison of acoustic waveforms. Such analysis may be useful
in further establishing risk for SDB, in the assessment of candidacy for various modalities of treatment, for more robust phenotypic analysis in genetic epidemiological studies, and to gauge the response to treatment. Furthermore, although our data provide additional evidence that reduction in airway caliber plays a role in SDB, the relatively small pharyngeal dimensions in women and African Americans without SDB suggest that factors in addition to those that influence directly pharyngeal CSA modify the predilection to SDB differentially across population subgroups”
