Currently endoscopic sinus surgery is the standard operation for rhinosinusitis and nasal polyps, including To determine the patterns and their prevalence of slopes of the ethmoidal roof assessed from the Computed A descriptive study was conducted at Srinagarind Hospital, Faculty of Medicine, Thailand. CTs of The downslope anteriorly and upslope posteriorly of the ethmoidal roof was found to be commonest in medio-sagittal and mid-sagittal planes. Its prevalence in medio-sagittal and mid-sagittal planes was 80.3% (95% CI 75.5-84.4) and 52% (95% CI 46.4-57.6). The second common pattern in medio-sagittal and mid-sagittal planes was a downslope pattern with the prevalence of 13% (95% CI 9.7-17.3) and 39.3% (95% CI 34-44). The downslope pattern was found to be the most prevalent for the latero-sagittal plane, accounting for 50.7% (95% CI 45.0-56.3), followed by downslope anteriorly and upslope posteriorly of 40% (95% CI 34.6-45.6). This is the first study to describe the patterns of slopes of the ethmoidal roof (anterior skull base) which
