在老年人的声嘶或咽异感症中、单侧假声带突出并非鲜见。由于其年龄和喉镜所见,常被怀疑为恶性肿瘤。然而经仔细喉部触诊,可发现甲状软骨有畸形,或与假声带突出有关。作者在一年半内见到10个假声带突出的病例,进行了CT扫描检查,并与正常喉的CT扫描相对比。病人均系老年男性,无喉外伤史。4例诉咽喉不适,7例声嘶;并有3例施行活组织检查,无恶性变。所有病例均系左侧假声带前半部突出。C T扫描显示两侧甲状软骨不对称,左侧甲状软骨明显凹陷。两侧甲状软骨在假声带平面构成的角小于正常对照组。 CT扫描的研究证明甲状软骨板的变形很可能引起假声带突出,此与老年人两侧甲状软骨不
In the elderly hoarseness or pharyngeal sensation, unilateral false vocal cord prominence is not uncommon. Because of its age and laryngoscope seen, often suspected of malignant tumor. However, careful throat palpation, can be found in deformity of thyroid cartilage, or with false vocal prominence. In a year and a half, the authors saw 10 cases of prominent false soundtracks, underwent CT scans and contrasted with normal laryngeal CT scans. Patients are elderly men, no history of laryngeal trauma. 4 cases of throat discomfort, 7 cases of hoarseness; and 3 cases of biopsy, no malignant change. All cases were prominent in the first half of the left falsetto. CT scan revealed asymmetric thyroid cartilage on both sides and left thyroid cartilage significantly depressed. Thyroid cartilage on both sides of the false vocal fold plane angle is smaller than the normal control group. CT scan studies have shown that deformation of thyroid cartilage plate is likely to cause false vocal cord prominence, with the elderly on both sides of the thyroid cartilage is not
