Methods Central point at the central clival depression was marked with the help of CT and stereotactic apparatus in 20 formalin-fixed cadaveric heads. The bone resection was divided into four steps via FLA:① drilling of the jugular tuberculum;② partial mastoidectomy;③ removal of the occipital condyle;④resection of the lateral mass of C1 with mobilization of the vertebral artery. After each step of the bone resection was completed, the exposed area of the central clival depression and the area of exposure 15 cm above the central point were calculated.

Methods From May 2007 to Oct 2007, 13 cases of soft foot and ankle tissue coloboma were repaired or reconstructed with this flap. The perforator branch was detected and earmarked by Doppler ultrasound. The flap axis was designed as the connection of internal condyle of tibia and the middle point between inner malleolus and achilles tendon based on anatomy. The pivot was designed in the point which perforator branch perforate the deep fascia. The flap dissociation was performed upon the deep fascia and the flap thickness can be modified during the operation.

And this paper also shows the structure and parameters of the optical system. The Xenon light of super high voltage is used as interferential source. The position of it is on the focus of the reflector of ellipsoid surface. After reflecting, its lights form a collective point . This point and objective focus of collimation lens are superposition. Though the collimation lens, the beam of light become parallel lights. Then though the Coude Reflector and radiation system of special prism, the lights become a beam of light with 3 ° emanative angle.
