The aim of this study is to evaluate the value of high resolution ultrasonography (HRUS) in diagnosis of various laryngeal lesions which already diagnosed with rigid endoscopy.
Prospective study with control group.
Sixty-six patients were suffering from throat symptoms and pre-examined by rigid endoscopy under local anesthesia and diagnosed to have a laryngeal lesion and 32 volunteers compose the control group. All 98 persons (patients and control groups) were examined by HRUS.
HRUS was helpful in describing various laryngeal lesions, vocal fold polyps (17) 25.7%, glottic cancer (6) 9.1%, epiglottic enlargement (2) 3.1% and one patient had laryngocele (1.5%). HRUS was highly significant in diagnosis of subglottic lesions (10) 15.2%. Also vocal fold mobility can be demonstrated by HRUS. While interarytenoid lesions (17) 25.8% and small laryngeal lesions as vocal fold nodules (13) 19.6% were difficult to be described.
Rigid endoscopy in laryngeal examination gives us large, bright image but it is difficult to diagnose patients with a sensitive gag reflex, patients with neck or jaw diseases or stridor and very difficult in infants and children. HRUS is an alternative method in diagnosis of some laryngeal lesions, and it is superior in the diagnosis of small subglottic lesions.
本研究旨在评估高分辨率超声检查（HRUS）在诊断已通过硬质内镜确诊的各种喉部病变中的价值。
设有对照组的前瞻性研究。
66例有咽喉症状的患者在局部麻醉下接受硬质内镜预检查，诊断为喉部病变，32名志愿者组成对照组。所有98人（患者组和对照组）均接受了HRUS检查。
HRUS有助于描述各种喉部病变，声带息肉（17例）占25.7%，声门癌（6例）占9.1%，会厌肿大（2例）占3.1%，1例患者患有喉囊肿（1.5%）。HRUS在诊断声门下病变（10例）占15.2%方面具有高度显著性。HRUS还可显示声带活动度。而杓间区病变（17例）占25.8%以及声带小结等小喉部病变（13例）占19.6%则难以描述。
硬质内镜检查喉部可提供大而清晰的图像，但对于有敏感咽反射的患者、患有颈部或颌部疾病或喘鸣的患者诊断困难，在婴幼儿中则非常困难。HRUS是诊断某些喉部病变的一种替代方法，在诊断小的声门下病变方面具有优势。
