The aim of this study was to evaluate the relationship between nasal septum deviation grade and inferior turbinate hypertrophy with the computed tomography (CT).
The paranasal sinus CTs of 82 patients with septum deviation were evaluated. Nonhypertrophied inferior turbinates on the deviated side of the nasal septum were accepted as the control group and hypertrophic inferior turbinates of the other side were taken as the compensatory group in the same patient. The turbinate bone, medial mucosa, lateral mucosa, septal deviation angle, and deviation volume were measured using three-dimensional CT.
The study group included 82 patients (M/F, 42/40) and ages ranged from 17 to 79 years (mean, 38.5 ± 14 years). There was a statistically significant positive correlation between the deviation angle and the deviation volume (p < 0.01). The measurements of the inferior turbinate bone and medial and lateral mucosal thickness were statistically different between the compensatory group and the control group (p < 0.01). There were no statistically significant differences in comparisons between the lateral and medial mucosal thickness with the deviation angle and the deviation volume in the two groups (p > 0.05). A positive correlation between the measurements of the deviation angle, deviation volume, and bone thickness was found statistically significant in the compensatory group (p < 0.05).
The compensatory hypertrophy of inferior turbinates in patients with nasal septum deviation is not only caused by mucosal hypertrophy, but also by hypertrophy of the inferior turbinate bone itself. The assistance of preoperative CT before septoplasty can be useful when deciding on the surgical technique to fix turbinate.
本研究旨在通过计算机断层扫描（CT）评估鼻中隔偏曲程度与下鼻甲肥大之间的关系。
对82例鼻中隔偏曲患者的鼻窦CT进行评估。将鼻中隔偏曲侧未肥大的下鼻甲作为对照组，将同一患者另一侧肥大的下鼻甲作为代偿组。使用三维CT测量鼻甲骨质、内侧黏膜、外侧黏膜、鼻中隔偏曲角度和偏曲体积。
研究组包括82例患者（男/女，42/40），年龄范围为17至79岁（平均38.5±14岁）。偏曲角度与偏曲体积之间存在统计学上显著的正相关（p<0.01）。代偿组与对照组在下鼻甲骨质及内侧和外侧黏膜厚度的测量上存在统计学差异（p<0.01）。两组中外侧和内侧黏膜厚度与偏曲角度和偏曲体积的比较无统计学显著差异（p>0.05）。在代偿组中，偏曲角度、偏曲体积和骨质厚度的测量之间存在统计学显著的正相关（p<0.05）。
鼻中隔偏曲患者下鼻甲的代偿性肥大不仅由黏膜肥大引起，还由下鼻甲骨质本身的肥大引起。在决定修复鼻甲的手术技术时，鼻中隔成形术前的CT辅助可能会有所帮助。
