Nasal foreign bodies are managed as an emergency for the risk of aspiration, yet it is not clear what proportion of bronchial foreign bodies actually originate in the nose. The aim of this study was to identify the origin of bronchial foreign bodies and estimate the risk of a nasal foreign body becoming impacted in the bronchial tree. We present a retrospective study of suspected bronchial foreign body cases at Addenbrooke's Hospital in Cambridge, UK, who underwent a bronchoscopy between 2002 and 2007. We further compare our experience with a literature review on bronchial and nasal foreign bodies to highlight important differences between these distinct clinical problems. Our experience shows that all cases of proven foreign body at bronchoscopy had ingested the foreign body orally. We could find only one case of a nasal foreign body in the literature that had been ingested during its removal, but no cases specifically entering the tracheo-bronchial tree. We therefore conclude that bronchial foreign bodies have their origin almost invariably in the mouth and the risk of a nasal foreign body entering the bronchial tree is negligible (<0.06%).
由于存在误吸风险，鼻腔异物被视为紧急情况进行处理，但尚不清楚支气管异物实际起源于鼻腔的比例。本研究的目的是确定支气管异物的起源，并评估鼻腔异物进入支气管树的风险。我们对英国剑桥阿登布鲁克医院2002年至2007年间接受支气管镜检查的疑似支气管异物病例进行了回顾性研究。我们进一步将我们的经验与关于支气管和鼻腔异物的文献综述进行比较，以突出这些不同临床问题之间的重要差异。我们的经验表明，所有经支气管镜检查证实为异物的病例都是经口摄入异物的。我们在文献中仅发现一例鼻腔异物在取出过程中被误吸，但没有专门进入气管支气管树的病例。因此，我们得出结论，支气管异物几乎都起源于口腔，鼻腔异物进入支气管树的风险可以忽略不计（<0.06%）。
