Abstract
A neonate with a left cervical mass was presented with airway obstruction at birth, requiring immediate endotracheal intubalion. CT-scan of the neck showed a large cyst which occupied the extralaryngeal region, pushing the trachea to the right side. Laryngoscopy revealed that the cyst was a lateral saccular cyst, which was covering up the laryngeal ventricle and extending through the crico-thyroideus muscle. The patient underwent the removal of the saccular cyst via the external approach with intraoperative laryngoscopic support. Histological examination of the resected specimen demonstrated that the cyst was lined with respiratory epithelium. The patient has been free from airway obstruction after surgery and doing well. Laryngeal cyst is an uncommon disease as a cause of infant airway obstruction. Our experience suggested that Laryngoscopy is a useful adjunct for the recognition, diagnosfs, and treatment of laryngeal cyst.
