Surgical Treatment of Dysphagia Secondary to Anterior Cervical Osteophytes Due to Diffuse Idiopathic Skeletal Hyperostosis

Diffuse idiopathic skeletal hyperostosis (DISH) is an ossifying and ankylosing skeletal condition that can be associated with DISH-related dysphagia in the case of cervical involvement. In contrast to most cases of dysphagia, which are managed conservatively, DISH-related dysphagia can be discouraging due to the progressive nature of DISH. We report two cases of DISH-related dysphagia that were treated with the surgical removal of osteophytes via an anterolateral approach. We were able to remove osteophytes using the bottleneck point as an anatomical landmark between the vertebral body and the bony excrescence. Patients' symptoms improved following osteophyte removal, without recurrence. In cases of DISH-related dysphagia, osteophyte removal using an osteotome could improve dysphagia safely and quickly.
