目的:通过给阻塞性睡眠呼吸暂停低通气量综合征(OSAHS)患者行咽侧成型术,评价其临床症状和MRI扫描咽部解剖学改变。方法:临床确诊为OSAHS患者28例为受试对象,术前行MRI和呼吸睡眠检测,狭窄部位在腭咽水平以上。对28例患者行咽侧成型术,于术后进行临床评价和MRI扫描。结果:受试对象术后均获较好疗效,与术前测值进行统计学分析有统计学差异。经2 a随访,有效率仍在92%以上。结论:咽侧成型术可能是治疗狭窄部位在腭咽水平以上OSAHS更好的方法。
OBJECTIVE: To evaluate the clinical symptoms and MRI anatomy of the pharynx by performing pharyngeal angioplasty on patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods: Twenty-eight patients with OSAHS were enrolled in the study. MRI and respiratory sleep were performed preoperatively. The stenosis was above the velopharyngeal level. Thirty-eight patients underwent pharyngeal angioplasty and postoperative clinical evaluation and MRI scans were performed. Results: The subjects were better postoperative efficacy, and statistical analysis of preoperative measurements were statistically significant. After 2 years of follow-up, the effective rate is still above 92%. CONCLUSIONS: Pharyngeal angioplasty may be a better method of treating OSAHS above the velopharyngeal level in the stenotic area.
