喉癌的发病率占全身恶性肿瘤的8.4％,占耳鼻咽喉科恶性肿瘤的36.1％,其中,声门上区癌占80％,声门区癌占19％,而声门下区癌仅占1％。由此可知,在喉癌病例中,99％的癌肿是远离环状软骨,在作全喉切除术时,可以考虑保留该软骨,用它作为气道的远端口,以免术后有瘘孔口径变窄之虞。 本文就我科在作喉全切除术时,保留环状软骨的临床观察加以探讨。 The incidence of laryngeal cancer accounted for 8.4% of systemic malignant tumors, accounting for 36.1% of otolaryngological malignancies, of which, supraglottic cancer accounted for 80%, glottis area cancer accounted for 19%, while the subglottic cancer accounted for only 1 %. This shows that in laryngeal cancer cases, 99% of the cancer is far from the annular cartilage, in total laryngectomy, you can consider retaining the cartilage, use it as a distal port of the airway to avoid postoperative fistula orifice diameter change Narrow danger. This article on my department in the laryngectomy, to retain the clinical observation of cricoid to be explored.
