This article reports 84 cases of ring deformity in our hospital from 1975 to 1992, of which 28 cases showed neurogenic dysphagia. These patients have normal swallowing function before symptoms of dysphagia occur. Patients with dysphagia progressive development of severe throat area with dysfunction, nasopharyngeal reflux and tracheal inhalation. All but one patient underwent posterior fossa decompression and posterior arch and C2,3 laminectomy. Two patients died of central respiratory failure and aspiration pneumonia after surgery. Twenty-one follow-up observations (6 months to 11 years with an average of 3.2 years) and 16 (76.2%) disappeared or improved. The author discusses the pathogenesis of the disease and diagnosis and treatment methods, and pointed out that the early recognition of intrinsic signs and surgical treatment of nerve function to promote recovery of great significance.
