ABSTRACT

Subglottic cyst is a rare cause of laryngeal tinnitus in infants and young children, and only a few cases have been reported at home and abroad. In this paper, we report the clinical characteristics and treatment experience of three cases of subglottic cysts in Children's Hospital of Nanjing Medical University. All the 3 childrem were prematurechildren, with a history of tracheal intubation, and the main symptoms were coughing and wheezing.Electronic nasopharyngolaryngoscopy revealed spherical neoplasm under the glottis. Neck computed tomography （CT） showed a slightly hypodense shadow with poorly defined borders, and no significant enhancement was observed after enhancement. Under the self-retaining laryngoscope, the new organisms were clamped and nibbled, and the cyst wall was cauterized by low temperature plasma. There was no recurrence in postoperative follow-up.
