CTICasesTracheobronchial Foreign Body Aspiration (Dental Drill Bit)
Imaging findings
Frontal and lateral chest radiographs demonstrate a metallic, drill-bit-shaped foreign body located within the posterior basal segment of the right lower lobe. The foreign body is successfully retrieved under fluoroscopic guidance using a micro snare.
Key takeaways
Aspiration of dental instruments (such as drill bits, files, or crowns) is a known iatrogenic complication of dental procedures. Because the right main bronchus is wider and more vertically oriented than the left, aspirated objects typically lodge in the right lower lobe. Fluoroscopically guided bronchoscopic snare retrieval is a highly effective method for extracting dense, metallic foreign bodies.
