Contact Nd.YAG laser conization (laser cone) was performed in 500 patients with preoperatively diagnosed cervical intraepithelial neoplasia (CIN) since September 1983. The patients treated were followed for 12 to 96 months (39.2 months on average). Average operation time was 11.4 minutes. A cure with laser cone (single treatment) was achieved in 98.6%, including cases with microinvasive and invasive carcinoma, post‐operatively. There were only 7 (1.4%) true residual cases of 47 cases (9.4% of total cases) with incomplete excision. High spontaneous cure rates (85.1%) in cases with incomplete excision are considered to be a characteristic of laser cone treatment. The contact laser cone method also got good specimens for histologic examinations. They gave a large amount of information for our follow‐up. The results indicate that contact Nd.YAG laser conization for CIN is an excellent conservative therapy from the point of cure rate, safety, indication, operation time and cone specimen, even compared with CO 2 laser conization.
