ABSTRACT
OBJECTIVE: To compare vertical and antero-posterior ratios of facial structures, pharyngeal dimensions and of the soft palate at the sagittal plane as well as the position of the hyoid bone using lateral cephalo-metric radiographs in patients with Obstructive Sleep Apnoea Syndrome (OSAS) and Metabolic Syn-drome (MS) and patients with OSAS without MS. SUBJECTS (MATERIALS) AND METHODS: Prospective and cross-sectional trial conducted between 2007 and 2009 at the Postgraduate Orthodontics Clinic, Aristotle University of Thessaloniki. Thirty nine patients aged between 29 and 62 years old (4 females and 35 males) with OSAS and AHI>30 were enrolled and assigned into two groups. The first included 19 subjects diagnosed with OSAS and MS and the second included 20 subjects diagnosed with OSAS, but with a negative diagnosis of MS. Lateral cephalometric radiographs of all subjects were obtained in Natural Head Position. The cephalomet-ric radiographs were processed electronically and resulted in measurements regarding skeletal struc-tures, pharyngeal dimensions, palate dimensions, and the hyoid bone position. A statistical analysis of the results was performed using Student's t-test and the Mann Whitney test. The level of significance was set at p<0.05. RESULTS: The subjects with OSAS and MS were found to have a greater distance between the supe-rior wall of the nasopharynx and the posterior nasal spine (PNS-SPW) (pcO.OOl). There were no statistical-ly significant differences between the groups in terms of the hyoid bone position, the soft palate dimension, the antero-posterior pharyngeal dimen-sions, the vertical facial structure ratios and the antero-posterior maxillary position. However, in rela-tion to mandibular position, the facial angle was found significantly increased in the group of subjects with OSAS and MS (p<0.017). CONCLUSIONS: This study compared the characteris-tics in lateral cephalometric radiographs of subjects with OSAS and MS and subjects with OSAS without MS and found that subjects with MS have a statisti-cally significant greater distance between the supe-rior wall of the nasopharynx and the posterior nasal spine, as well as a greater facial angle.
