Pseudotumour of the craniovertebral junction is an uncommon cause of high cervical myelopathy in the elderly. The anterior transoral approach is the preferred means of accessing these lesions. An "odontoid sparing" transoral approach, in which there is only minimal bone removal, is thought to preserve stability of the craniovertebral junction, obviating the need for posterior stabilisation. This report is of an 82 year old man who developed fatal atlanto-axial instability following an odontoid sparing transoral resection of a pseudotumour. This complication has not previously been described and its occurrence has important implications for the surgical management of this condition.
颅颈交界区假瘤是老年人高位颈髓病的罕见病因。经口前路是处理这些病变的首选方法。一种“保留齿状突”的经口入路，即仅进行极少的骨质切除，被认为可保持颅颈交界区的稳定性，从而无需进行后路稳定手术。本文报道了一名82岁男性，在经口保留齿状突切除假瘤后发生致命性寰枢椎不稳。此前尚未描述过这种并发症，其发生对该疾病的手术治疗具有重要意义。
