Abstract: Objective:To classify congenital laryngeal cysts in 62 newborn or infants, and to discuss the characteristics of different operation mode.Method:The clinical data of 62 infants with laryngeal cysts treated were reviewed retrospectively. After the examination of neck palpation, laryngoscope and imaging (CT or MRI),all patients were under general anesthesia of laryngeal cyst excision. we select operation mode according to the classification. Classification include:61 cases of cysts were confined to the larynx, 1 case was beyond the larynx. Surgical managements include:an excision through external carotid approach in 1 case beyond the larynx,61 cases had endoscopic excision under general anesthesia (12 cases with traditional bite exception, 12 cases with powered system and 37 cases with low-temperature radiofrequency ablation). Result:The operations was successful. No recurrence was found after 0.5 to 7 years follow-up.Conclusion:To chose surgical management after classification and preoperative assessment, which could avoid unnecessary opening surgical approaches, reducing the recurrence, and preventing repeated endoscopic treatment or tracheotomy. The low-temperature radiofrequency ablation had the advantages of short operation time, less bleeding, little injury, low recurrence rate and light postoperative reaction. It is worthy of clinical promotion.
