Abstract

Chiari malformasyonları (CM), serebellar tonsillerin servikal spinal kanala inmesiyle karakterize edilen bir dizi anomaliyi ifade eder. Bu malformasyonlar, siringomiyeli, hidrosefali, spina bifida ve skolyoz gibi anormalliklerle ilişkilendirilebilir. Ayrıca, kraniyoservikal bileşke anomalileri, endokrinopatiler, kranyosinostoz ve sendromik bozukluklar da CM ile bağlantılıdır. CM'nin tedavisi cerrahidir ve bilinen bir tıbbi tedavisi yoktur. CM tanısı alan hastalara genellikle cerrahi tedavi veya takip önerilir. Cerrahi müdahalenin literatürde desteklendiği görülse de hangi prosedürün en uygun olduğu ve ameliyatın ne zaman yapılması gerektiği konusunda tartışmalar bulunmaktadır. Bu makalede, CM'nin tarihsel arka planı, anatomik formları, patofizyolojisi, klinik sunumu, diğer hastalıklarla ilişkisi ve literatür ışığında tanı prosedürleri incelenecektir.

Abstract

Chiari malformations (CM) refer to a series of anomalies characterized by the descent of cerebellar tonsils into the cervical spinal canal. These malformations can be associated with abnormalities such as syringomyelia, hydrocephalus, spina bifida, and scoliosis. Additionally, cranio-cervical junction anomalies, endocrinopathies, craniosynostosis, and syndromic disorders are also linked to CM. The treatment of CM is surgical, and there is no known medical therapy. Patients diagnosed with CM are typically advised to undergo surgical treatment or follow-up. Although surgical intervention is supported in the literature, debates exist regarding which procedure is most suitable and when surgery should be performed. In this article, we will examine the historical background of CM, its anatomical forms, pathophysiology, clinical presentation, relationship with other diseases, and diagnostic procedures in the light of the literature.
