Abstract:           Background and purpose: Surgical operation is the main method in the treatment of laryngeal carcinoma, but different patients have different impacts on the survival time and the quality of life with different type of operation. This study was to analyze the methods of surgical treatment and its long-term effect of laryngeal carcinoma, to increase survival rates, laryngeal function reservation and reconstruction and improve life quality. Methods: A total mumber of 424 patients of laryngeal carcinoma treated with surgical treatment during between Jan. 2002 and Dec. 2012 were researched by clinical follow-up and data analysis. Surgical method: CO₂ laser-assisted laryngeal microsurgery for laryngeal tumors for 50 cases, frontal partial laryngectomy or modified thyroid cartilage window partial laryngectomy without tracheostomy for 42 cases, vertical frontolateral partial laryngectomy for 119 cases, horizontal partial laryngectomy and extended subtotal laryngectomy for 22cases, anastomosis of pharynx and trachea for 4 cases, supra cricoid partial laryngectomy for 129 cases (CHEP of them for 103 cases, CHP for 26 cases), total laryngectomy for 58 cases, cervical lymph node dissection at the same term for 121 cases. Results: Partial laryngectomy without tracheostomy for 92 cases (21.7%), total laryngectomy for 58 cases (13.7%); decannulation rate was 86.5%, vertical frontolateral partial laryngectomy of them for 93.2%, horizontal partial laryngectomy of them for 90.9%,supra cricoid partial laryngeal of them for 82.2%; laryngeal function reservation rate for 86.3%; all patients did outpatient review and telephone follow-up, 9 cases loss to follow-up, a total of tumor recurrence, cervical lymph node metastasis and distant metastasis were 41 cases, mostly occurred in 1 year after surgery; death for 57 cases, relapse of them for 8 cases, cervical metastasis for 13 cases, pulmonary metastasis for 5 cases, hepatic metastases for 2 cases, brain metastases for 1 case, esophagus metastases for 1 case, pulmonary infection for 6 cases, acute renal failure for 2 cases, unknown reason for 19 cases, according to Kaplan-Meier to count survival rate, 3-year and 5-year survival rate were 90.7% and 84.1%, relapse and metastasis were the main causes of death. Conclusion: Surgical treatment is the main therapy mode of laryngeal carcinoma. We choose individualized surgical methods for patients according to tumor staging, invasion site, age, occupation and education background of patient, health condition and so on. On the premise that tumor is completely cut off, we always advocate function surgery and minimally invasive surgery, and adopt comprehensive treatment at the same time, in order to increase survival rates, lesson suffering and improve life quality as far as possible.
