A patient with a total laryngectomy and tracheoesophageal voice prosthesis presented with tracheobronchial aspiration of a Phillips-head screw that was swallowed inadvertently and aspirated around a loose-fitting prosthesis. A modified esophagram showed a screw in the right lung and free leakage of barium from the cervical esophagus around the prosthesis into the tracheobronchial tree. Chest radiographs and CT confirmed a screw in a right lower lobe bronchus with postobstructive pneumonia. When this complication occurs, it is important to extract the foreign body and, if necessary, to adjust or remove the prosthesis to prevent future aspiration pneumonias or foreign body aspiration.
一名接受全喉切除术并植入气管食管发音假体的患者，不慎吞下一枚十字槽盘头螺钉，该螺钉经松动的假体周围被误吸入气管支气管。改良食管造影显示一枚螺钉位于右肺，钡剂从假体周围的颈段食管自由漏入气管支气管树。胸部X光片和CT证实一枚螺钉位于右下叶支气管，伴有阻塞性肺炎。当出现这种并发症时，取出异物并在必要时调整或移除假体以预防未来的吸入性肺炎或异物吸入非常重要。
