为探讨声门上型喉癌杓状软骨区受累的病理学特点及其与声带活动度的关系,对53例声门上型喉癌全切除标本,行整喉连续切片分析。结果发现杓状软骨区受累率为45.3％,杓区上部受累为主。杓区中、重度受累声带固定频率为75％,阴性、轻度受累声带固定频率为36.4％,二者之间差异显著(P<0.01)。杓状软骨受累率为24.5％。杓状软骨受累声带固定频率为53.8％,未受累声带固定频率为52.5％,二者之间无显著性差异(P>0.05)。结论:声门上癌可向杓区发展,未发现该区有阻止肿瘤扩展的迹象。杓区受累程度与声带固定有关。
To investigate the pathological features of the arytenoid laryngeal carcinoma in the arytenoid cartilage region involved and its relationship with the activity of the vocal cords, 53 cases of supraglottic laryngeal carcinoma were resected and serial sections of the throat were analyzed. The results showed that the arytenoid cartilage zone involvement rate was 45.3%, mainly in the upper area of scoop area. In the scoop area, the fixation frequency of severe acoustic involvement was 75%, while the fixation frequency of negative and mild involvement was 36.4%. There was significant difference between the two (P <0.01). Articular cartilage involvement rate was 24.5%. The frequency of fixation of the arytenoid cartilage was 53.8%, and the frequency of unaccounted vocal cord fixation was 52.5%. There was no significant difference between them (P> 0.05). CONCLUSIONS: Supraglottic carcinomas develop in the dipper zone and no signs of tumor expansion are found in this area. Acre zone involvement and vocal cord fixation.
