Bottom Line: It is very important for the neurosurgeon to choose the right approach in order to reach the lesion without harming the other intact structures.In the following text these approaches will be described.These approaches are:1) pterional approach2) frontolateral approach3) transsphenoidal approach4) suboccipital lateral approachThese approaches can be extended and combined with each other.In the following we want to enhance this philosophy.

ABSTRACT
The skull base surgery is one of the most demanding surgeries. There are different structures that can be injured easily, by operating in the skull base. It is very important for the neurosurgeon to choose the right approach in order to reach the lesion without harming the other intact structures. Due to the pioneering work of Cushing, Hirsch, Yasargil, Krause, Dandy and other dedicated neurosurgeons, it is possible to address the tumor and other lesions in the anterior, the mid-line and the posterior cranial base. With the transsphenoidal, the frontolateral, the pterional and the lateral suboccipital approach nearly every region of the skull base is exposable.In the current state many different skull base approaches are described for various neurosurgical diseases during the last 20 years. The selection of an approach may differ from country to country, e.g., in the United States orbitozygomaticotomy for special lesions of the anterior skull base or petrosectomy for clivus meningiomas, are found more frequently than in Europe.The reason for writing the review was the question: Are there keyhole approaches with which someone can deal with a vast variety of lesions in the neurosurgical field?In my opinion the different surgical approaches mentioned above cover almost 95% of all skull base tumors and lesions. In the following text these approaches will be described.These approaches are:1) pterional approach2) frontolateral approach3) transsphenoidal approach4) suboccipital lateral approachThese approaches can be extended and combined with each other. In the following we want to enhance this philosophy.

Figure 17: After resection.

Mentions: Neuropathological findings revealed parts of an epithlial cyst inflammatory cell infiltration in connective tissue stroma. The MRI showed a cystic lesion above the pituitary gland (Figure 15). We performed a frontolateral approach, in order to expose the Rathke's cleft cyst (Figure 16) and to remove it (Figure 17).
