Serial radiographic studies were used in a prospective study of tracheostomy healing in 30 consecutive infants and children. The examinations were simple, required no anesthesia or sedation, and were coordinated with decannulation of the tracheostomy. In 22 of 30, the tracheostomy site healed normally; in four of these 22 patients the primary cause for obstruction persisted. In 19 of 22 the radiologic study served as an alternative to bronchoscopy before decannulation. Particularly in small infants, the features of normal healing vary in the first days; temporary narrowing of the tracheal lumen can occur at the stomal site and mimic early granulations. After 1 month the trachea is normal except for minor changes at the previous site of the tracheostomy.
对30例连续的婴幼儿气管切开术愈合情况进行了前瞻性研究，采用了系列影像学检查。这些检查操作简单，无需麻醉或镇静，且与气管切开管拔除相协调。30例中有22例气管切开部位愈合正常；这22例患者中有4例梗阻的主要原因仍然存在。22例中有19例在拔除气管切开管前，影像学检查可替代支气管镜检查。特别是在小婴儿中，愈合初期正常愈合的特征有所不同；气管造口部位可出现气管腔暂时变窄，类似早期肉芽组织。1个月后，除气管切开术先前部位有轻微变化外，气管恢复正常。
