X线头影测量能较好的显示上气道软组织和硬性解剖结构的关系,为阻塞性睡眠呼吸暂停低通气综合征(obstructive sleepapnea hypopnea syndrome,OSAHS)患者寻找阻塞部位提供依据。该方法定位较准确,可重复性好,价廉,使用简便,已形成一整套标志和测量体系,在OSAHS的早期研究阶段就得到应用,从形态学上获得了对该病的大量认识,为探讨该病的发病机制,并指导临床的诊断和治疗发挥了重要作用。本文对该方法在OSAHS诊断、治疗中的应用和自身的局限性等问题做一综述。
X-cephalometry can better show the relationship between soft tissue and rigid anatomy of the upper airway, and provide a basis for finding the obstructive site in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). The method has the advantages of accurate positioning, good reproducibility, low cost and easy to use. A set of sign and measurement system has been formed. It has been applied in the early research stage of OSAHS and obtained a great deal of morphological understanding of the disease. Explore the pathogenesis of the disease, and guide the clinical diagnosis and treatment has played an important role. This article reviews the method in the diagnosis and treatment of OSAHS and its limitations.
