OBJECTIVE
The preservation of the olfactory tract during bifrontal approach for lesions located in the frontal skull base and the supra- and parasellar region has not previously been investigated.
METHODS
In our study 12 patients underwent surgery for various lesions via the basal subfrontal route. All patients were observed prospectively, olfaction testing was performed pre- and postoperatively by an independent otorhinolaryngologist.
RESULTS
We obtained complete preservation of the olfactory tracts and normal postoperative olfaction in all 12 cases.
CONCLUSION
The bifrontal approach allowed a bilateral, wide operative field with excellent orientation and views of important structures. The shortcoming of this method, damage of the olfactory tracts and postoperative anosmia can be overcome.
目的
此前尚未对经双额入路处理位于额颅底以及鞍上和鞍旁区域病变时嗅束的保留情况进行研究。
方法
在我们的研究中，12例患者经额下基底入路接受了针对各种病变的手术。所有患者均进行前瞻性观察，术前和术后由一名独立的耳鼻喉科医生进行嗅觉测试。
结果
我们在所有12例病例中均实现了嗅束的完全保留以及术后嗅觉正常。
结论
双额入路可提供双侧广阔的手术视野，对重要结构的定位和视野极佳。该方法的缺点，即嗅束损伤和术后嗅觉丧失是可以克服的。
