Abstract: Objective: To investigate the operative indicatio of selective neck dissection in patients with T2 - T3 laryngeal squamous cell carcinoma. Method: From January 2005 to February 2011, 18 cases with T2-T3 laryngeal squamous cell carcinoma were treated in our department. 10 cases admitted before 2008 received selective neck dissection. Under the pro-operation evaluation by neck contrast enhancement CT and ultrasound, 8 cases who had not metastases signs admitted after 2008 have not received selective neck dissection. All 18 cases received conventional post-op radiotherapy (the total dose was 50-70 Gy). Results: In follow-up periods from 3-6 years, among the all 10 cases received selective neck dissection, 1 case death because asthma 4 years after operation, 1 case death because local recurrence 3 years after operation, 8 cases were disease free survivals. In follow-up periods from 1-3 years, all 8 cases have not received selective neck dissection were disease free survivals. Conclusion: Under the pro-operation evaluation by neck contrast enhancement CT and ultrasound，and regularly follow-up, for T2 - T3 laryngeal squamous cell carcinoma cases who had not metastases signs, selective neck dissection was not necessary . It was a secure treatment strategy.

Key words: T2-T3 laryngeal squamous cell carcinoma, selective neck dissection
