INTRODUCTION: The diagnosis of temporal bone fractures (TBF) is based on radiological imaging. The most widely used classification divides fractures into longitudinal, transverse, and mixed. In recent years, other classifications have emerged to better predict clinical manifestations.
OBJECTIVES: To review computed tomography (CT) images of TBF, define their radiological pattern, and study the concordance of the observed findings with those described in the radiological report. To analyse the association between fracture types and clinical findings. To study the impact of mastoid pneumatization on fracture characteristics.
METHODS: Retrospective study of 110 TBF diagnosed with CT between January 2016 and May 2019.
RESULTS: Fifty-two transverse (47%), 34 longitudinal (30%), and 19 mixed fractures (17%) were identified with good interobserver agreement (k = .637). Longitudinal fractures were associated with conductive hearing loss (P < .001) and transverse fractures with sensorineural hearing loss (P = .005). Of the fractures, 8.2% showed involvement of the otic capsule, and were associated with sensorineural hearing loss (P < .001), facial paralysis (P = .019) and vertigo (P= .035). Fractures were more frequent in cases of greater pneumatization, and the involvement of the otic capsule in cases of very good pneumatization (P = .024).
CONCLUSIONS: The traditional classification of TBF is reproducible. Its association with clinical findings improves when the involvement of the otic capsule is also analysed. Mastoid pneumatization is not a protective factor for TBF or for involvement of the otic capsule.
