To evaluate the sonographic appearance of laryngeal cysts, ultrasound examinations of 7 patients were evaluated retrospectively. The ultrasound studies were correlated with endoscopic findings. In two cases, the diagnosis was confirmed histologically, and in 4 patients, a CT examination was additionally performed. The endolaryngeal space could be well seen if the thyroid cartilage was not calcified (n = 6), whereas in one patient, the endolaryngeal part of the cyst could not be seen because of complete calcification of the thyroid cartilage. The laryngeal cysts presented as unechoic (n = 4) or hypoechoic (n = 3) masses, which demonstrated smooth margins in all cases and ranged in size from 6 to 38 mm. In three cases, the cyst was located in the endolaryngeal space, and in 4 cases, it extended cranial of the thyroid cartilage into the pre-epiglottic space. All cysts were closely related to the inner surface of the thyroid cartilage, from which they were delineated by a thin hyperechoic band in all cases.
为评估喉囊肿的超声表现，对7例患者的超声检查进行回顾性分析。超声检查结果与内镜检查结果进行对比。其中2例经组织学确诊，另外4例患者还进行了CT检查。若甲状软骨未钙化（n = 6），则可清晰观察到喉内间隙，而1例患者因甲状软骨完全钙化，无法观察到囊肿的喉内部分。喉囊肿表现为无回声（n = 4）或低回声（n = 3）肿块，所有病例边界均光滑，大小在6至38毫米之间。3例囊肿位于喉内间隙，4例囊肿延伸至甲状软骨上方进入会厌前间隙。所有囊肿均与甲状软骨内表面紧密相连，在所有病例中均由一条薄的高回声带将其与甲状软骨分隔开来。
