目的：鼻窦的解剖结构变异在耳鼻喉科医生进行鼻窦手术时具有实际意义。本研究的目的是评估的副鼻窦的临床显着的解剖变异的患病率。方法：435计算机断层扫描（CT）检查成人阿曼患者进行了前瞻性分析，以确定副鼻窦的临床显着的解剖变异的患病率。结果：49%的患者鼻Agger细胞异常（95% CI：44-54%），49%为耳甲泡（95%CI：44-54%），Haller细胞24%（95%CI：18-31%），前筛顶不对称32%（CI：29-37%），Onodi细胞8%（CI：5%-10%）。颅底类型如下：1型30%（n=107; 95% CI：25-35%），2型34%（n=123; 95% CI：29-39），3型36%（n=130; 95% CI：31-41%）。许多其他手术的显着的解剖变异，在少数（1-3）偶然identified.CONCLUSION：存在的鼻窦解剖变异的知识具有临床意义，因为它最大限度地减少了手术并发症的可能性。解剖变异的发生率存在种族差异。需要进一步研究解剖变异与临床疾病的相关性。
OBJECTIVE: Anatomic structural variations of the paranasal sinuses have a practical significance during surgical procedures conducted on the sinuses by otolaryngologists. This study aims to evaluate the prevalence of clinically significant anatomical variations of the paranasal sinuses.METHODS: A prospective analysis of 435 computed tomography (CT) examinations of adult Omani patients was conducted to determine the prevalence of clinically significant anatomical variations of the paranasal sinuses. A total of 360 CT scans were included from January 2009 to January 2010.RESULTS: The findings showed abnormal Agger nasi cells in 49% of cases (95% CI: 44-54%), concha bullosa in 49% (95% CI: 44-54%), Haller cells in 24% (95% CI: 18-31%), asymmetry in anterior ethmoidal roof 32% (CI: 29-37%), Onodi cells in 8% (CI: 5%-10%). The type of skull base were as follows; Type 1 was 30% (n=107; 95% CI: 25-35%), Type 2 was 34% (n=123; 95% CI: 29-39), and Type 3 was 36% (n=130; 95% CI: 31-41%). Many other surgically significant anatomical variations in small numbers (1-3) were incidentally identified.CONCLUSION: Knowledge of the presence of anatomical variations of the sinuses has a clinical significance as it minimizes the potential for surgical complications. There is an ethnical difference in the prevalence of anatomical variations. Further studies of anatomical variations with clinical disease correlations are needed.
