Because of considering congenital diseases or space-occupying diseases of throat, we performed neck CT examination, which indicated linear diaphragm in glottis (Figure 1A). Laryngoscopy revealed that the anterior commissure of glottis was covered by webbed connection, which blocked nearly two thirds of glottis (Figure 1B). The mucosal smoothness was improved after cryotherapy (Figure 1C).
