Lateral neck radiographs performed to localize impacted fishbones have a low sensitivity. The differing radio-opacities of the bones of various fish species may be a reason for this. A cadaver head and neck and the rib bones of 10 species of fish were used in this study. A laryngoscope was used to introduce a fishbone into the vallecula and then into the hypopharynx of the cadaver. A lateral radiograph was taken in each case. Ten control films were taken. The radiographs were independently reviewed by a consultant radiologist and otolaryngologist. The presence and position of any bone seen was noted. There was no inter-observer variation. All species of fishbone were visible. One bone was not seen by either observer. Visualization of fishbones is more dependent on position than their degree of radio-opacity. Routine radiography is recommended.
为定位嵌顿鱼骨而进行的颈部侧位X线片敏感性较低。各种鱼类骨头不同的X线不透光性可能是其原因。本研究使用了一具尸体的头颈部以及10种鱼类的肋骨。使用喉镜将一根鱼骨放入尸体会厌谷，然后放入下咽。每种情况均拍摄一张侧位X线片。拍摄了10张对照片。放射科顾问医师和耳鼻喉科医师独立阅片。记录所见到的任何骨头的存在及位置。观察者之间没有差异。所有种类的鱼骨均可见。有一根骨头两位观察者均未看到。鱼骨的显影更多地取决于其位置而非X线不透光程度。建议进行常规X线摄影。
