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

在颅面入路切除颅底肿瘤的情况下，需要切开面部皮肤并劈开面部骨骼。因此，这种操作是困难的，并导致严重的侵入。此外，术后美容和功能的发病率也是显着的。由于这些原因，这种颅底手术没有成为标准化。为建立和规范微创颅底外科手术，减少术后功能和美容并发症，我们对以下两个项目进行了研究。首先，我们通过对Thiel法固定尸体解剖的研究，发展了新的微创手术方法。其次，我们用吲哚菁绿色荧光法对面部骨骼和软组织进行了分割，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.
