引言鼻中隔的形态变异与鼻窦病理学有关,并在内窥镜手术中提出了挑战。目的本研究旨在评估成年尼日利亚人鼻中隔变异的患病率。方法本研究在三角洲州立大学教学医院放射科进行,尼日利亚,在道德批准之后。对336名成年人的脑计算机断层扫描(CT)扫描图像进行了鼻中隔变异评估。测量了鼻中隔偏曲的角度,并对严重程度进行了分类。使用IBMSPSSStatisticsforWindows分析数据,版本23.0(IBMCorp.,Armonk,NY,美国)。偏差角以平均值和标准偏差表示。变体的频率以百分比表示。学生t检验用于比较偏差角度,而卡方检验用于比较不同组的频率。P值<0.05被认为是统计学上显著的。结果鼻中隔直型和斜型的患病率分别为59.5%和40.5%,分别。偏差在女性中占主导地位(46%),更频繁地,中度严重程度(75%)。男性的偏离角度(12.55±2.99°)明显大于女性(11.13±2.41°;p=0.003)。鼻刺的患病率为11.9%,与鼻中隔偏曲共存的比例为5.06%。10例患者(3%)出现室间隔气化。结论鼻中隔偏曲多发生在女性和左侧;然而,男性的偏离角度明显较高。鼻中隔骨刺和气化是最不常见的变体。
Introduction The morphological variants of the nasal
septum have been implicated in sinus pathology and pose a challenge during endoscopic surgeries. Objective The present
study aimed at evaluating the prevalence of nasal
septum variants in adult Nigerians. Methods The present
study was performed at the Radiology Department of Delta State University Teaching Hospital, Nigeria, following ethical approval. Brain computed tomography (CT) scan images of 336 adults were evaluated for nasal
septum variants. The angle of the deviated nasal
septum was measured, and the severity was classified. Data were analyzed using IBM SPSS Statistics for Windows, version 23.0 (IBM Corp., Armonk, NY, USA). The angle of deviation was presented in means and standard deviation. Frequencies of the variants were presented in percentages. The Student t -test was used to compare the angle of deviation, while the chi-squared test was used to compare the frequencies in the different groups. A p-value < 0.05 was considered statistically significant. Results The prevalence of straight and deviated nasal septum was 59.5% and 40.5%, respectively. Deviation was predominant in females (46%) and, more frequently, of moderate severity (75%). The angle of deviation was significantly larger in males (12.55 ± 2.99°) than in females (11.13 ± 2.41°; p = 0.003). Nasal spur had a prevalence of 11.9%, and its coexistence with deviated nasal septum was observed in 5.06%. Septal pneumatization was seen in 10 patients (3%). Conclusion Deviation of the nasal septum occurred more in females and toward the left; however, the angle of deviation was significantly higher in males. Nasal septal spur and pneumatization were the least prevalent variants.
