I. Blindness – the enemy of survival quality Indirect optic nerve injury is mostly seen in traffic accidents or other causes of cranial and facial closed injury, with serious consequences, often resulting in the patient’s vision loss or even blindness, affecting work and life. At present, most scholars at home and abroad believe that those who have visual impairment after craniocerebral trauma, as long as the diagnosis is optic nerve injury without eye injury, should undergo optic nerve canal decompression while applying high-dose steroid drugs. II. Historical review: As the surgical treatment of traumatic optic nerve damage, optic nerve decompression is divided into two types: transcranial and transnasal. In comparison, the transcranial procedure has the following advantages: 1) good surgical exposure and adequate decompression at the orbital apex; 2) incision of the optic nerve sheath in the outer upper quadrant, which can effectively avoid accidental injury to the ophthalmic artery and its branches; 3) facilitates the management of simultaneous combined craniocerebral trauma; 4) no special equipment requirements, which is easy to be popularized in primary hospitals. In transcranial optic nerve decompression, it is divided into two basic procedures: transfrontal approach and pterygoid approach. Compared with the transfrontal approach, the pterygoid point approach has the advantages of shorter surgical path, more adequate decompression, and can release the compression of the arteriolar nerve by the fracture of the pterygoid pterygoid and play the role of arteriolar nerve decompression at the same time. On the basis of extensive review of data and cadaveric dissection, we proposed the transcranial epidural approach to the anterior bed prominence for optic nerve canal decompression. This topic was combined with transcranial optic nerve canal decompression, especially the anatomical features related to the transcranial epidural point of entry anterior bed synovectomy optic nerve canal decompression were studied in detail. Based on the anatomical study, the modified procedure of epidural anterior bed process resection for optic nerve decompression was used in clinical cases and was recognized by international authorities for its higher safety, practicality, scalability and satisfactory results of optic nerve decompression. The paper was published in Neurosurgery (SCI Impact Factor 2.56), the top journal of neurosurgery in the United States. This marks our department’s undisputed position in the international field of optic nerve surgery and skull base surgery techniques. In addition, the epidural anterior bed-frontal resection technique is the core technique for managing the most complex intracranial aneurysm, the pars plana (ophthalmic) aneurysm, and is an important marker of a neurosurgeon’s ability to manage aneurysms. Proficiency in this technique marks a new leap in our aneurysm management skills. The epidural anterior bed-synovectomy optic nerve decompression procedure developed by us has the following advantages over the intradural procedure: 1) more reliable intraoperative localization of bony structures; 2) less damage to the intra-dural structures DD brain tissue and cranial nerves; 3) as the optic column is removed, the optic nerve canal is completely communicated with the supraorbital fissure, and the purpose of full decompression of the optic nerve canal can be achieved without cutting the general tendon ring of the rectus muscle during surgery; 4) the procedure is more The surgery is faster. Clinical application results and its prospects At present, the clinical application of epidural anterior bed-optic nerve decompression in Qilu Hospital has exceeded 40 cases (including patients who came from outside the province), and it has been performed in Jinan Fourth People’s Hospital, Yinan Branch of Qilu Hospital, Second Hospital of Shandong University, General Hospital of Jinan Military Region, Jinan Third People’s Hospital, Tengzhou People’s Hospital, Shanghe County People’s Hospital, Zhangqiu City People’s Hospital, Zhangqiu City Chinese Hospital, and Zhangqiu City Hospital. People’s Hospital, Zhangqiu City Hospital of Traditional Chinese Medicine, Qingzhou City People’s Hospital and other hospitals. V. Misconceptions A considerable part of doctors in the province, especially ophthalmologists, have common misconceptions due to the influence of old concepts. For patients with complete blindness due to traumatic optic nerve damage, he or she will say to the patient that “the patient has completely lost the function of the optic nerve, and surgery will not help”; if the patient retains some vision, he or she will say that “as long as there is vision, he or she can recover by himself or herself, and surgery is not needed. “In short, optic nerve decompression is useless. In fact, this statement is more of a pretext due to the fact that doctors are not confident in their own techniques at all. According to domestic and foreign experience and our own experience, both patients who are blind and those who have some residual vision have a chance to recover.
