ABSTRACT

A major complication in oral and maxillofacial surgery is when fragments of instruments and material—objects such as anesthetic needles, rotary instruments, surgical blades, suture needles, extraction elevators, and prosthetic implants—are retained within the patient’s oral region. This is a problem which can be exacerbated when dental organs are accidentally displaced into adjacent anatomical spaces during the attempted extraction. Though interest in this topic has waned—indeed it is one that has received very little attention in recent literature—, it is a common problem in our practice. The post-event period can be disconcerting both for the surgeon and for the patient. The recovery period can be slow and troublesome, though this depends on a whole range of factors, such as the size, location, and shape of the lodged instrument and of the neighboring anatomical structures. A factor that complicates the removal even more is the displacement of retained objects over time. Fluoroscopy has proven extremely useful in the process of removing these objects, thanks to the intraoperative real-time image that the fluoroscope provides. We present a case of fluoroscopy-guided extraction of an upper third molar accidentally displaced into the pterygomaxillary space.
