The evaluation of 128 slice spiral CT for soft palate, hard palate and mandible in patients with obstructive sleep apnea hypopnea syndrom / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To discuss the soft palate, hard palate and mandibule for the pathogenesis and clinical treatment of patients who have obstructive sleep apnea hypopnea syndrome.@*METHOD@#There were 52 patients with OSAHS diagnosed by the PSG and 32 cases of normal healthy volunteers in our hospital. All objects were given 128 slice spiral CT scan of the upper airway. We measured the related indexes of the soft palate, hard palate and mandible, then analysed statistical differences between them and did Pearson correlation analysis with apnea hypoventilation index (AHI), average blood oxygen saturation (MSaO2) in PSG.@*RESULT@#Compared with the control group, the soft palate length [(37.93 ± 5.20)mm VS (33.52 ± 4.25)mm] and the distance between mandible with cervical vertebra [(75.00 ± 7.10)mm VS (69.93 ± 5.58)mm] increased significantly, but the distance of trailing edge of hard palate to inferior margin of slope significantly reduced [(42.57 ± 4.52)mm VS (45.80 ± 2.94)mm, P 0.05).@*CONCLUSION@#The soft palate, hard palate and mandibular are some of the important risk factors of OSAHS, and they also have reference value for the choice of clinical treatment operation. Preoperative CT examination can offer help in the treatment of OSAHS.
