Abstract

〔Purpose〕There are two types of patients who visit our clinic with a chief complaint of snoring or sleep apnea; one is patients with a diagnosis of OSAHS, and the other is without any diagnosis. Comparisons of the two groups of patients were made. Also, the effects of our oral appliance were examined. Furthermore, cephalometric analysis was performed to evaluate the change in maxillofacial morphology of OSAHS patients with and without oral appliance.<br>〔Methods〕BMI, ESS and AHI of 242 patients with complains of snoring or sleep apnea were studied, and differences between two groups were analyzed. The effects of oral appliance on OSAHS patients were analyzed by improvement ratio of AHI. Also, the relationship between improvement of AHI and change of maxillofacial morphology with and without oral appliance was evaluated using cephalometric analysis.<br>〔Results〕Out of 242 patients with snoring or sleep apnea complaints, 71 (29.3％) patients did not have a diagnosis of OSAHS. Within these 71 patients, 44 (62.0％) patients were diagnosed as OSAHS after the first visit to our clinic. There was no difference between two groups on BMI, ESS or AHI. Also AHI scores of severe OSAHS patients improved when oral appliance was applied. In cephalometric analysis, the respiratory tract was widely expanded with oral appliance.<br>〔Conclusion〕These results suggested that there are many potential OSAHS patients. Also oral appliance was effective even for severe OSAHS patients.
