To investigate the clinical features of laryngeal papilloma in children.Method:In a group of 62 patients with laryngeal papilloma in children,the tumors of 28 patients were cut under the direct laryngoscope,34 patients were treated with laryngeal micro-laser operation.Result:The post-operation followup ranged from 2 to 5 years,the cure rate of 2 years was 51.61%.Conclusion:The clinical features of this disease include rapid development,a large lesion,and it is often found in the infraglottic cavity.Furthermore,we believe that in order to eliminate the tumors more accurately and decrease recurrence,microlaser surgery and the use of interferon is very necessary.
