後頭骨陥没骨折の犬の1手術例 A Surgical Case of Dipressed Fracture of Occipital Bone in Dog

後頭骨陥没骨折で、中枢性前庭症状を呈した犬に対して、MRIおよびCT検査にて確定診断を行い、外科的に骨片除去を行った。手術時、骨折は左側環椎後頭関節部にまで及んでいたが、関節の再建や固定は不可能であった。骨片摘出による小脳の露出部は側頭筋の筋膜で被覆した。術後1年経過した現在、症例は後遺症なく生活している。

MRI and CT examinations were performed on a dog with central nervous system signs and a diagnosis of occipital depressed skull fracture was made. The boney fragments were removed surgically. During the surgery the fracture was found to be extending into the left atlanto-occipital joint, however neither repair nor arthrodesis of the joint were possible. The fragments were removed and the exposed cerebellum was closed using temporal muscle fascia. The patient lives normal life without any symptom or sequela now at a year post surgery.
