摘要
The relationship between temporal bone pneumatization (TBP) pattern and sinus mucous thickness grading on computed tomography scans of paranasal sinuses was investigated. In this cross-sectional study, a total of 200 temporal bones and paranasal sinuses were evaluated in CT scans of 100 patients with chronic sinusitis (CRS). The mucosal thickness of paranasal sinuses was classified into two groups (0–6 and 7–12) according to the Lund-Mackay (LM) staging system. Also, pneumatization patterns of petrous apex and perilabyrinthine regions were classified according to Jadvah et al. method. Data were analyzed using Chi-square and Fisher’s exact tests. The most common pneumatization pattern in the petrous apex was pattern A (49.5%) and in the perilabyrinthine region was pattern B (50%). In the petrous apex, the highest frequencies of pattern A (51.7%) and pattern C (24.6%), among other pneumatization patterns, were found in score range of 7–12 and 0–6, respectively, which was statistically significant (P = 0.017). Although in the perilabyrinthine region, the highest frequencies of pattern A (24.1%) and pattern C (32.7%) were in LM score ranges of 7–12 and 0–6, respectively, no significant difference was found (P = 0.589). The petrous apex pneumatization decreases with an increase in the severity of CRS, which can be in response to the eustachian tube dysfunction and common pathogens with CRS. A similar relationship was also found in the perilabyrinthine region, although it was not statistically significant. No significant relationship between TBP and severity of CRS was found in the age and sex groups.
