Insights
High-resolution computed tomography (HRCT) with 3D reconstruction significantly improves the diagnosis of traumatic auditory ossicular chain fractures. This technique offers clearer, more stereoscopic imaging compared to standard HRCT, aiding surgical planning.
Area of Science:
- Otolaryngology
- Medical Imaging
- Trauma Surgery
Background:
- Traumatic auditory ossicular chain interruption presents diagnostic challenges.
- Accurate preoperative assessment is crucial for effective surgical intervention.
Purpose of the Study:
- To evaluate the clinical utility of HRCT 3D reconstruction for traumatic auditory ossicular chain fractures.
- To compare the diagnostic accuracy of 3D reconstruction versus standard HRCT.
Main Methods:
- Retrospective analysis of 14 patients with traumatic auditory ossicular chain interruption.
- All patients underwent HRCT scanning and 3D reconstruction for preoperative evaluation.
- Surgical exploration results were used as the gold standard for comparison.
Main Results:
- Standard HRCT showed only a 28.57% coincidence rate with surgical findings.
- 3D reconstruction achieved an 85.71% coincidence rate with surgical findings.
- 3D reconstruction provided clearer, more stereoscopic visualization of ossicular chain destruction.
Conclusions:
- Preoperative 3D reconstruction enhances the clarity and accuracy of diagnosing auditory ossicular chain destruction.
- This technique facilitates individualized surgical planning and risk assessment for traumatic ossicular chain injuries.
Abstract:
Objective:To investigate the clinical value of HRCT three-dimensional reconstruction technique in traumatic auditory chain traumatic fracture. Method:The clinical data of 14 patients with traumatic ear ossicular chain interruption were analyzed retrospectively. To evaluate the injury site and degree of the auditory chain before surgery, all the 14 patients underwent,HRCT scanning and three-dimensional reconstruction. The reconstructed auditory chain was observed from multiple angles and compared with the surgical exploration results under microscope. Result:The coincidence rate between ossicular chain injury observed by temporal bone HRCT scan before operation and ossicular chain injury observed during surgery was only 28.57%, the coincidence rate between ossicular chain injury observed during surgery and ossicular chain injury observed by three-dimensional reconstruction is 85.71%.Therefore, three-dimensional reconstruction imaging technique could give the doctor more clearly and stereoscopic images for the destruction of ossicular chain. Conclusion:Preoperative three-dimensional reconstruction can display and diagnosis of auditory ossicular chain destruction more clearly. It can be used to accurately evaluate auditory ossicular chain pathological changes, to develop individualized surgical plans and assess the risk of surgery.
