Preservation of the olfactory tract during use of the bifrontal approach for the treatment of lesions located in the frontal cranial base and the supra- and parasellar regions has not been previously investigated.
In our study, 12 patients underwent surgery, via the basal subfrontal route, for treatment of various lesions. All patients were observed prospectively, and olfactometry was performed pre- and postoperatively by an independent otorhinolaryngologist.
We obtained complete preservation of the olfactory tracts and normal postoperative olfaction in all 12 cases.
The bifrontal approach yields a bilateral wide operative field with excellent orientation and views of important structures. The shortcomings of this method, i.e., damage to the olfactory tracts and postoperative anosmia, can be overcome.
以往尚未对采用双额入路治疗位于额颅底及鞍上和鞍旁区域病变时嗅束的保留情况进行研究。
在我们的研究中，12例患者通过额下基底入路接受手术以治疗各种病变。所有患者均接受前瞻性观察，术前和术后由独立的耳鼻喉科医生进行嗅觉测量。
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。
双额入路可提供双侧广阔的手术视野，对重要结构具有极佳的定位和视野。该方法的缺点，即对嗅束的损伤和术后嗅觉丧失，可以得到克服。
