METHODS: We designed a superior turbinate lateralization (STL) procedure that displaces the entire ST bone laterally by eliminating the connection between the posterior ST and the anterior wall of the sphenoid sinus. The effect of the STL procedure was investigated in terms of anatomy and olfactory function.
RESULTS: ESS with the STL procedure was performed on seven patients with chronic rhinosinusitis and nasal polyps. The cross-sectional area of the OC at 3 months postoperatively was significantly larger than that before ESS. In addition, the Open Essence test and questionnaires revealed significantly improvements in sense of smell. Airflow in the OC was significantly higher in STL procedure group than in the non-STL procedure group.
CONCLUSIONS: The STL procedure enlarges the bony framework of the OC, and by increasing OC airflow, facilitates the transport of odorants to the olfactory epithelium, thereby improving olfactory perception.
方法:我们设计了一种上鼻甲偏侧化(STL)手术,该手术通过消除后ST与蝶窦前壁之间的连接,使整个ST骨侧向移位。从解剖结构和嗅觉功能方面研究了STL程序的效果。
结果:对7例慢性鼻-鼻窦炎和鼻息肉患者行STL手术的ESS。术后3个月OC的横截面积明显大于ESS前。此外,OpenEssence测试和问卷调查显示,嗅觉有了显着改善。STL手术组OC中的气流明显高于非STL手术组。
结论:STL程序扩大了OC的骨框架,通过增加OC气流,促进气味物质向嗅觉上皮的运输,从而改善嗅觉感知。
