The surgical findings observed in a series of 209 consecutive patients with craniovertebral anomaly are presented. The high prevalence of basilar impression in the Northeast of Brazil is noteworthy. There were 28 (13.3%) patients with basilar impression alone, 10 (4.7%) cases of pure Arnold-Chiari malformation and in 171 (81.8%) cases the basilar impression was associated with Arnold-Chiari malformation. This study reflects our surgical experience of the pathology in a 17-year period (1971-1987). It reflects also the peculiarities of neurosurgical practice in an undeveloped region of this Country. The literature is extensively reviewed.
本文呈现了对连续209例颅颈畸形患者的手术观察结果。值得注意的是，巴西东北部基底凹陷的高患病率。单纯基底凹陷患者有28例（13.3%），单纯阿诺德-奇阿利畸形10例（4.7%），171例（81.8%）患者基底凹陷与阿诺德-奇阿利畸形相关。本研究反映了我们在17年期间（1971 - 1987年）对该病理学的手术经验。它也反映了该国一个不发达地区神经外科实践的特点。对相关文献进行了广泛综述。
