Abstract:The maxillofacial area is prone to the lodging of foreign objects in tissue, which are often difficult to remove. We describe a patient in whom foreign objects that were lodged deep in facial tissue were removed by using an optical navigational guidance system. An 84-year-old man presented with wounds on his face after falling through a glass door. Computed tomography images showed multiple radiopaque markers in the pterygopalatine fossa and temporal region. An optical navigation system was used to locate the foreign objects, and the glass pieces that were embedded in the skin and deeper tissues were extracted by using a guided navigation system with the patient under general anesthesia. Thus, foreign objects lodged in the maxillofacial area were successfully removed by using a guided navigation system in a minimally invasive manner.
