A study for establishment of the less invasive and low risk craniofacial approach in the skull base surgery

对于颅面入路切除颅底肿瘤，需要面部皮肤切开和面部骨骼劈裂术。因此，该手术难度大，侵袭性大。此外，术后美容和功能的发生率也是显著的。由于这些原因，这种颅底手术并没有变得标准化。为了建立和规范侵袭性较小、术后功能和美容并发症较少的颅底外科，我们研究了以下两项内容。首先，通过对Thiel法固定身体的解剖研究，提出了侵袭性较小的新的手术方法。其次，我们应用吲哚青绿荧光法对面部骨骼和软组织进行分割，以保持良好的血流。

In the case of craniofacial approach for extirpation of the skull base tumor, facial skin incision and splitting of the facial skeleton are required. Therefore, this operation is difficult and results in severe invasion. Furthermore, the postoperative cosmetic and functional morbidity is also remarkable. For these reasons, this skull base surgery does not become standardized. We studied the following two items for the purpose of establishment and standardization of the skull base surgery with less invasiveness and postoperative functional and cosmetic morbidity. Firstly, we developed the new surgical methods with less invasiveness by study of the dissection of the cadaver fixed using Thiel method. Secondly, we examined the technique of division of the facial skeleton and soft tissue by the method of indocyanine green fluorometry in order to preserve good blood flow.
