Transoral Endoscopic Resection of High Cervical Osteophytes with Long-Term Symptom Resolution: Case Series, Imaging, and Literature Review

ACOs are a potential cause of dysphagia, and their diagnosis is best made with computed tomographic imaging and oropharyngeal swallow study. Although high ACOs at C1-C2 are a rare finding, here we show with an exemplary case and small case series that they can be effectively treated with transoral endoscopic osteophytectomy.
