With the development of Neurosurgery technology, there has been a qualitative leap forward with the appearance of microanatomy, which makes the deep brain tumors which were hard to be achieved in the past, and effectively reduces the mortality of patients. Petrous apex is a cone-shaped part of the anteromedial part of the temporal bone, which is deep. It has been a challenging area for surgical anatomy for a long time. In this paper, fresh adult perfused cadaveric head specimens and dry adult cadaveric head specimens were taken as the experimental objects. The anterior wall of sphenoid sinus and the internal septum of sphenoid sinus were excised under neuroendoscope. The structures of the lateral wall of sphenoid sinus were identified and dissected. The lateral wall of sphenoid sinus and the bone of skull base were opened with micro drill, The meninges were exposed and cut open, and the related structures were dissected, observed and photographed. The experimental results show that it is relatively safe to operate in the range of less than 8mm, and the rock tip can be found accurately. The measurement of the bony structure of the skull base is helpful for the surgeon to judge the course of the internal carotid artery and its adjacent structure.

This paper attempts to analyze the related factors of cervical cancer combined with immunotherapy, taking cervical cancer patients as the experimental object, through the establishment of cervical cancer model, combined with natural immune agonists, immune activated monoclonal antibody and HPV polypeptide to explore its prevention or treatment of cervical cancer immune research.The results showed that the number of people with bad habits was more, and the incidence rate of cervical cancer was relatively high. However, for those without formal work, the number of cases of bad sexual behavior is more, and HPV transmission is easier, which also provides convenience for the occurrence of cervical cancer. The mechanism of action of tumor therapeutic vaccine is different from that of cytotoxic drugs. Its particularity lies in that the induction of specific anti-tumor immune response needs a certain period of time before it can be transformed into clinical effect; and patients with recurrence or metastasis usually receive multiple rounds of treatment, which may affect the immune system and reduce the efficacy of the vaccine.
