茎突过长症并非罕见,其诊断主要依靠病史、体检及影像学检查。随着影像技术的不断发展,螺旋CT三维重建技术成为检查茎突的一种新的方法,与X线平片比较,它能更清楚地显示茎突在三维空间的全貌,从而更准确地测量其长度。本文通过20例就诊于耳鼻咽喉科门诊,疑为茎突过长症的患者行 Styloid process is not uncommon, the diagnosis depends mainly on medical history, physical examination and imaging studies. With the continuous development of imaging technology, spiral CT three-dimensional reconstruction technology has become a new method of checking the styloid process, compared with the X-ray film, it can more clearly show the entire styloid in three-dimensional space, so as to more accurately measure Its length. This article through the 20 cases were treated in otolaryngology clinic, suspected patients with styloid process
