ABSTRACT
OBJECTIVE@#This study aimed to determine the clinical effectiveness of double-shaft classification and sequential diagnosis and treatment of food impaction.@*METHODS@#A total of 227 patients with food impactionwere subjected to double-shaft classification and subsequently treated by sequential diagnosis and treatment method. Treatment effectiveness was evaluated according to the subjective feelings of patientsat five time points (immediately after treatment and at 1, 3, 6, and 12 months after treatment).@*RESULTS@#The average scores of patient's subjective perception were 2.00, 1.93, 1.59, 1.20, and 0.98 immediately and at 1, 3, 6, and 12 months after treatment, with treatment-efficiency values of 87.17%, 81.70%, 73.21%, 55.80%, and 44.59%, respectively. There were differences in scores of patient's subjective perception at each time point (P< 0.05).@*CONCLUSIONS@#Double-shaft classification and sequential diagnosis and treatment can effectively guide the treatment of food impaction.
