Title Equivocal Results for Hyoid Bone Position and Obstructive Sleep Apnea Severity
Clinical Question For patients with obstructive sleep apnea, does a more inferiorly displaced hyoid bone correlate with a more severe form of OSA?
Clinical Bottom Line Results for this question are equivocal. More research is needed to accurately answer this question.

Comments on
The Evidence
Validity: patients varied widely from the different studies used in this review; of the 4 that supported this cat, the first one looked at lateral cephalometric radiograph measurements compared to severity (Bates and McDonald, 2005). The second one was a retrospective study of 206 Japanese men and their respective clinical records (Kubota, 2005). The third cited article studied cephalometric studies (Nagunuma 2002). The last article was a randomized retrospective study of 94 lateral cephalograms between April 1996 to September 1997. For the Gulati article, that article could not invalidate the previous articles because there were a small number of patients in the severe-OSA group in this study. Another limitation is that this was a retrospective study. Another problem was that a quarter of the original sample was excluded due to missing information.
Applicability This evidence is applicable to the proposed population in the PICO question.
