Management of Penetrating Skull Base Injury: A Single Institutional Experience and Review of the Literature

Figure 3

Photography showed the entry point (black triangle, ▼) of foreign body on face and incision for a frontotemporoorbitozygomatic approach (a). Short piece of foreign body (simple arrow, ←) in the face was exposed and removed by a maxillofacial surgeon (b). The infratemporal fossa was opened to expose the long piece of foreign body (c), and it (hollow arrow, ) was removed in a retrograde fashion. During the removing process, yellowish pus (asterisk, ) was drained into the infratemporal fossa (d). Photography displayed short piece (simple arrow, ←) and long piece (hollow arrow, ) of the foreign body (e). Postoperative skull radiography suggested complete removal of the foreign body (f). The small bone fragment (hollow arrow head, ➤) was left in place due to its close relationship with branch of MCA (g). Three-month follow-up MRI revealed no abscess formation (h). The patient recovered uneventfully (i). MCA, middle cerebral artery; MRI, magnetic resonance imaging.
