Chiari Malformation Clinical Trial
Official title:
Clinical Study of Atlanto-occipital Decompression Lateral Joint Release Combined With Occipital-neck Fusion in the Treatment of Chiari Malformation Combined With Type II Skull Base Depression
The research background of this study is that Chiari malformation (CM) is a congenital malformation in the foramen magnum region, often associated with syringomyelia, basilar depression, odontoid dislocation and other craniocervical junction deformities. The traditional surgical method for Chiari malformation with skull basilar depression is simple decompression without fixation, so it cannot effectively maintain the stability of the cervical spine and reduce the compression of the brainstem and cervical cord, often resulting in poor curative effect and aggravated symptoms. The cervical spine is the most flexible and most mobile part of the spine, and the instability of the cervical spine will directly affect the quality of life of patients after surgery. Subsequently, with the continuous advancement of technology and the continuous development and improvement of surgical methods, Investigators can relieve spinal cord compression by using atlanto-occipital decompression and dissection followed by C1/2 lateral arthrolysis combined with occipitocervical fusion. So, is this surgical combination the most effective surgery for patients with Chiari malformation and type II skull basilar depression? How should doctors adjust to the best surgical approach to treat patients with Chiari malformation and type II skull basilar depression? These questions have long puzzled neurosurgeons. By conducting this research, investigators hope that participants can participate in it, and work with them to answer this question, and jointly promote the development and progress of doctors' careers, while benefiting more patients.
