Correlation of hearing outcome in otic capsule sparing temporal bone fractures using temporal bone sub-site classification: a cross-sectional descriptive study

Abstract

Background Head injury most commonly occur following road traffic accidents. Often hearing loss and other otological injuries are missed in view of serious head injury or other visible bodily injuries, leading to delayed recognition of problems. There is a need for early clinical and radiological indicators which can predict adverse outcome. Early diagnosis of otological injury during initial evaluation of the head injury has given some clues regarding the severity of hearing outcomes and such correlation has been attempted in this study. Two-year cross-sectional study involving head injury patients with radiological evidence of temporal bone fracture were assessed for hearing impairment. Results Thirty-seven patients who satisfied the inclusion criteria were assessed. Fifty-one percent patients had conductive hearing loss. 35.14% of the patients had involvement of mastoid, external auditory canal, and middle ear involvement. A weakly positive correlation was noted between otic capsule sparing fracture and hearing loss. (R value + 0.2064). Conclusion Weak correlation was observed between temporal bone sub-site classification and severity of hearing loss in otic capsule sparing temporal bone fractures.

Clinical application of high-resolution spiral CT scanning in the diagnosis of auriculotemporal and ossicle

“…This research further advances diagnostic capabilities by investigating the complementary nature of the CNN-UNet model with high-resolution CT images [ 19 ]. Several essential tasks, such as ossicle segmentation, fracture identification, and disruption cause categorization, characterize this investigation [ 20 ]. This study aims to improve the speed and accuracy of clinical decision-making by automating these processes.…”
