This report presented the case of a difficult-to-remove needle foreign body. The patient had a dental procedure in which a 30-gauge needle was lost in the gingival buccal sulcus. Several attempts at removal were unsuccessful. The patient presented to the otolaryngology clinic with trismus, pain with mastication, intermittent right otalgia, and numbness of the right cheek.
The needle was finally localized in the infratemporal fossa and removed by using image guidance technology.
This case demonstrated an approach to a difficult-to-locate foreign body removal and the importance of intraoperative imaging in foreign body localization.
Foreign bodies of the infratemporal fossa and posterior orbit are better removed via endoscopic than open technique.
本报告介绍了一例难以取出的针头异物病例。患者接受了牙科手术，期间一根30号针头掉入牙龈颊沟。多次尝试取出均未成功。患者因牙关紧闭、咀嚼时疼痛、间歇性右耳痛和右脸颊麻木而就诊于耳鼻喉科诊所。
针头最终定位在颞下窝，并使用影像引导技术将其取出。
该病例展示了一种定位困难的异物取出方法以及术中成像在异物定位中的重要性。
颞下窝和眶后部的异物通过内镜手术比开放手术更适合取出。
