“…here are many reports in the literature describing CT of temporal bone trauma, [1][2][3][4] detailing fracture plane orientations, [4][5][6] ossicular disruptions, otic capsule involvement, 4,5 associations with air in the temporomandibular joint (TMJ), 7 facial nerve injury, [4][5][6] and fracture mimics, to name a few broad categories. 8 Temporal bone fractures involving the tympanic plate (Figs 1 and 2), however, are under-recognized and have received little attention beyond isolated case reports involving mandibular trauma.…”

“…Thus, if the fracture line reaches those organs, it may induce sensorineural hearing loss [4], CSF otorrhea, or facial nerve paralysis [5,6]. According to a classification based on petrous bone involvement, Ishman reported that petrous bone fractures result in ten times greater likelihood of CSF leak and three times greater likelihood of facial nerve injury compared with non-petrous bone involvement [2].…”

The aim of this study is to evaluate the feasibility of multiplanar reconstructive (MPR) imaging of temporal bone CT in the diagnosis of temporal bone fracture with oticcapsule-sparing facial nerve paralysis. Twelve patients with traumatic facial nerve paralysis with oticcapsule sparing and temporal bone fractures were selected. Multiplanar reconstruction images were obtained with the V-works 4.0 software program (Cybermed, Seoul, Korea) using axial scanning of high-resolution temporal bone CT of the fracture line. The clinical profiles of the patients displaying temporal bone fractures were examined in relation to the findings. Multiplanar images of the fracture line provided information regarding the direction of the external force that fractured the temporal bone. The fracture line was more continuous in the MPR images than in the axial view. All patients showed an imaginary extended fracture line directed toward the otic capsule. The direction of the fracture line toward the middle ear cavity is important, as it may suggest insult to the otic capsule. The MPR image parallel to the fracture line of the temporal bone provides a guideline for the vector of the force that induced the fracture. Thorough investigation of the critical organs during surgical exploration is recommended if the direction of the fracture in the MPR image points toward the otic capsule in the middle ear even if the fracture line relative to the otic capsule is not well defined in the axial or CT view.

“…MR is required for cases of FN paralysis unexplained by CT findings because of its sensitivity in demonstrating the facial nerve itself and possible pathologic changes [3], (Figures 1,2).…”

In the past decades, treatment of the temporal bone traumas (TBTs) was undeniably improved by advances in neuroradiological and in neuro-oto-surgical fields. However, these advances did not systematically enhance the quality of the approach to TBTs. Maybe they did not systematically target towards treatment-guidelines standardization. We suggest a simplified approach to TBTs, trying to enhance the communication among the different specialists involved in the matter, above all between the radiologists and not-radiologists.
