目的 :探讨喉良性增生性病变对发声功能的影响及CO2 激光显微外科术后的转归特点。方法 :对2 92例喉良性增生性病变患者 (声带息肉、任克水肿、声带小结、囊肿、慢性肥厚性喉炎 )的流行病学、嗓音声学、形态及CO2 激光显微外科术后转归进行分析。结果 :声带小结患者均为青年女性 ,2 3.0 8%与职业有关 ;任克水肿为中老年患者。声带息肉及小结病变局限 ,手术仅涉及声带局部 ,术后改善明显 ,术后 1个月达正常状态 ;任克水肿患者术后 1个月改善明显 ,术后 3个月恢复最佳稳定 ;声带囊肿患者术后 1个月声音达最佳状态 ,但由于病变切除术后局部存在缺损 ,一定程度上影响预后 ;慢性肥厚性喉炎患者术后改善不满意。术后声门上代偿纠正均不明显。结论 :喉良性增生性病变主要累及声带被覆层 ,嗓音声障碍的程度及疗效与受累范围有关 ,激光显微外科手术可以保留良好结构及功能。除外科治疗外 ,还应及时矫正不良发声习惯等因素 ,以期获得最佳疗效。
Objective: To investigate the effects of benign and malignant laryngeal lesions on vocal function and the outcome of CO2 laser microsurgery. Methods: The epidemiology, vocal acoustics, morphology and CO2 laser microsurgery of 2 92 patients with benign prostatic hyperplasia (vocal cord polyp, Renke edema, vocal nodules, cysts and chronic hypertrophic laryngitis) Analyze. Results: All the patients with vocal nodules were young females, 2 3.08% were related to occupations; Renke edema was middle-aged and elderly patients. Vocal cord polyp and the limitations of the lesion, the operation involves only the local vocal cord, postoperative improved significantly, 1 month after the normal state; Renke edema significantly improved after 1 month postoperative 3 months to restore the best stability; vocal cords Patients with cyst reached the best state at 1 month after operation, but the local defect after the resection of the lesion affected the prognosis to a certain extent. Patients with chronic hypertrophic laryngitis were not satisfied with the postoperative improvement. Postoperative supraglottic compensation is not obvious. CONCLUSION: The main pathological changes of benign laryngeal glands are involving the vocal cord coating, the extent of the voice dysfunction and the curative effect with the affected area. Laser microsurgery can retain good structure and function. In addition to surgical treatment, but also promptly correct the bad habit of voice and other factors, in order to obtain the best effect.
