Comparison of Preoperative Temporal Bone HRCT and Intraoperative Findings in Patients with Chronic Otitis Media

Conclusion: The compatibility of HRCT findings with surgical findings in determining the presence of dehiscence of the facial canal and its tympanic segment was moderate, while it was good in determining the presence of dehiscence of the lateral semicircular canal and the defect of the dural plate.

📌 3 Key Takeaways

🎯

Objective & Hypothesis:Objective: The aim of the present study was to investigate the diagnostic confidence level of preoperative 160-slice computed tomography (CT) findings compared with that of perioperative findings about anatomic variations in the structure of the facial canal, lateral semicircular canal, and dural plate.

📊

Key Findings & Data:Materials and Methods: Fifty-five patients who presented with middle ear pathology to Department of Otolaryngology, Afyon Kocatepe University Faculty of Medicine were included in the study, and the mean age was 42 (±15.55) years.

Abstract

Objective: The aim of the present study was to investigate the diagnostic confidence level of preoperative 160-slice computed tomography (CT) findings compared with that of perioperative findings about anatomic variations in the structure of the facial canal, lateral semicircular canal, and dural plate. Materials and Methods: Fifty-five patients who presented with middle ear pathology to Department of Otolaryngology, Afyon Kocatepe University Faculty of Medicine were included in the study, and the mean age was 42 (±15.55) years. Preoperative CT images of the temporal bone were obtained by an 80-detector row CT scanner.Results: The sensitivity, specificity, and positive and negative predictive values of preoperative high-resolution CT (HRCT) were 52%, 88%, 73%, and 75%, respectively, for determining the presence of facial canal dehiscence; 50%, 89%, 71%, and 76%, respectively, for determining the presence of tympanic segment dehiscence; 71%, 96%, 71%, and 96%, respectively, for determining the presence of lateral semicircular canal dehiscence; and 100%, 96%, 50%, and 100%, respectively, for detecting the presence of dural plate defects. Conclusion: The compatibility of HRCT findings with surgical findings in determining the presence of dehiscence of the facial canal and its tympanic segment was moderate, while it was good in determining the presence of dehiscence of the lateral semicircular canal and the defect of the dural plate.
