Abstract
Our department of pediatric otorhinolaryngologic diseases examines and treats many cases of hearing impairment and upper respiratory airway obstruction issues.
We reported on a bifida epiglottis of an infant (4-month-old male), an epiglottis cyst of a 1-month-old male, a laryngeal web (1-month-old female), a larynx papilloma（recurrent respiratory papillomatosis of 9-month-old female）, a congenital subglottic stenosis (2-month-old male) and a congenital laryngeal atresia (30-week-old female).
We disuccused the symptoms, diagnosis, and the therapies for each disease.
