Sleep respiratory disorder in children is frequently attributable to upper airway obstruction due to tonsillar hypertrophy. Children with sleep respiratory disorder sometimes have chest deformity such as funnel chest or pigeon chest, suggesting that upper airway obstruction can affect the respiratory system.Using the measurement of the mesopharyngeal pressure while asleep, we recently studied the relationship between upper airway obstruction and chest deformity. In children with tonsillar hypertrophy, we examined the presence or absence of chest deformity and assessed the degree of upper airway obstruction based on the mesopharyngeal pressure. In 33 children in whom chest deformity was found, the shape of the thorax was observed for a long period after adenotonsillectomy.The following results were obtained. (1) Most of the children with chest deformity had sleep respiratory disorders such as snoring, retracting respiration and sleep apnea. (2) The incidence of chest deformity was elevated as the mesopharyngeal pressure amplitude became higher. (3) In most cases, the chest deformity gradually improved within several years after adenotonsillectomy. (4) Upper airway obstruction due to tonsillar hypertrophy seemed to be one of the main causes for chest deformity.
