Abstract

Objectives

Cerebellar tonsillectomy is often performed for relief of symptoms associated with Chiari type I malformation (CMI). Nonetheless, the idea of removing supposedly healthy central nervous tissue has been a source of concern for neurosurgeons. The aim of this paper is to determine the histological changes in the cerebellar tonsils of patients with a wide range of symptoms and conditions related to CMI.

Materials and methods

The cerebellar tonsils of 43 pediatric patients with CMI were sent to pathology for histological examination.

Conclusion

The cerebellar tonsils in a great majority of CMI patients can be abnormal. We suggest that the reported histological findings are secondary to injury and ischemia.
