磷酸钛钾激光声带切除术治疗早期声门癌的疗效观察

目的：探讨磷酸钛钾（ＫＴＰ）激光声带切除术治疗早期声门癌的效果。方法：对３０例行激光声带切除术者（激光组）和１８例行喉裂开声带切除者（喉裂开组）术后的喉内结构变化、音质、生存质量等进行对比分析。结果：激光组半年后在原声带处长出一新声带，音质明显提高接近正常，生存提高较高。喉裂开组无新声带形成，音质半年内较好而后持续较差，生存质量在拔管前较低，拔管后同激光组。术后观察２～４年，激光组２例复发，喉裂开

Clinical study on treatmen of early glottic carcinoma with different cordectomy

OBJECTIVE: To explore the advantage of KTP laser cordectomy in the treatment of early glottic carcinoma. METHOD: Follow-up observation on 30 patients who had KTP laser cordectomy and 18 patients who had laryneal split cordectomy was applied, then their postoperative laryngeal structure's change, the quality of voice and the quality of life (QOL) were compared and analyzed. RESULT: The patient group treated by KTP laser grew out a piece of new cord just at the place where it was excised after half a year, and the quality of voice was obviously improved near to norm, and they had higher QOL. On the contrary, the other group had no newly grown cord, their quality of voice was better in the first half year but was worse last out. Their QOL was lower than the laser group before decannulation and the same as the laser group after the decannulation. There are 2 cases recurrented in the laser group and 1 case recurrented in the laryneal split group, the two groups all had no metastasis and death in laryneal carcinoma by 2-4 years follow up postoperation. CONCLUSION: On the basis of effecting radical cure, the early glottic carcinoma treated with non-contact KTP laser with suspension laryngoscope can result in good recuperating in laryngeal structure, less injury and high QOL. So it makes micro-injury treatment in laryngeal carcinoma come true and better than the laryngeal split cordectomy.
