INTRODUCTION
Foreign body impaction within the maxillofacial region is not an uncommon occurrence. Imaging of such objects is of paramount importance to their retrieval in order to assess their relation to vital structures as well as avoid disruption of such structures while retrieving the foreign bodies. We report a case of wooden foreign body which traversed the maxillofacial region, imaging of which posed a significant challenge.
METHODS
A sixteen year old female presented with a wooden foreign body impaction following a road traffic accident. Challenges in the course of investigation and events during the surgical retrieval of the foreign body are described.
RESULT
An unusual case of foreign body impaction transecting the right orbit, right antrum and the pharynx is presented. The inability of both Computed Tomographic scan and Ultra Sound scan to identify the path and relations of the impacted foreign body was also discussed.
CONCLUSION
Computed Tomography and Ultrasonography may not be sufficient to delineate the path and relations of an impacted foreign body especially if the nature of the foreign body is not metallic.
引言
异物嵌顿于颌面区域并非罕见情况。对此类异物进行成像对于取出异物至关重要，以便评估其与重要结构的关系，并在取出异物时避免破坏这些结构。我们报告一例木质异物横穿颌面区域的病例，对此异物进行成像构成了重大挑战。
方法
一名16岁女性在道路交通事故后出现木质异物嵌顿。描述了调查过程中的挑战以及异物手术取出过程中的事件。
结果
呈现一例异物嵌顿横断右眼眶、右鼻窦和咽部的不寻常病例。还讨论了计算机断层扫描和超声扫描均无法识别嵌顿异物的路径和关系的情况。
结论
计算机断层扫描和超声检查可能不足以描绘嵌顿异物的路径和关系，特别是如果异物的性质不是金属的。
