TY - CHAP M1 - Book, Section TI - Chapter 33. Stridor in Children A1 - Yates, Philip D. A2 - Lalwani, Anil K. PY - 2012 T2 - CURRENT Diagnosis & Treatment in Otolaryngology—Head & Neck Surgery, 3e AB - Stridor is a harsh noise produced by turbulent airflow through a partially obstructed airway. It may be inspiratory, expiratory, or both (biphasic). The term stertor is used to describe airway noise originating in the nose, nasopharynx, and oropharynx; therefore, stridor is generally of laryngeal or tracheal origin. As a general rule, inspiratory stridor originates from the supraglottis and glottis, expiratory stridor from the trachea, and biphasic stridor from the subglottis. There is a wide variety of causes of airway obstruction in children (Table 33–1). This chapter describes the more common laryngeal abnormalities that can cause stridor.
