ABSTRACT
<p><b>OBJECTIVE</b>To discuss the effect of electric coagulation through bronchoscopy in diagnosis and treatment of congenital vallecular cyst in children.</p><p><b>METHOD</b>Ten cases of congenital vallecular cyst in the study with age ranged from 21 days to 4 years and 10 months were treated with electric coagulation through bronchoscopy. The therapeutic effect was evaluated by endoscopic and clinical manifestation. And all the patients were followed-up for 6-12 months.</p><p><b>RESULT</b>All the patients obtained 3-5 times electric coagulation. After the operation, the cyst decreased in size, epiglottis softening was subsided, uplift uncompression, dyspnea and laryngeal stridor were improved obviously.
