[The reclassification of sudden deafness].

Reclassified the total deafness and flat type of sudden deafness,identified the relationship between new classification and hearing prognosis.To analyze 192 cases of patients with sudden deafness,especially for 159 cases of flat type and total deafness patients for further curve type classification,classified as rise,decline and consistent,analysis the possible factors with hearing in multiple factors using regression analysis.According to age group of 45 years old,>0.05,the difference has not statistically significant;Course of the disease according to the 0-7 days and 14 days more,<0.01,=4.291;8-14 days and 14 days,<0.05,=2.983;According to the flat type and total deafness grouping,<0.05,=0.409;According to the curve type of deafness,the difference between rise type and total deafness was significant,<0.01,=9.692;Decline type,consistent type compared to total deafness type,there is no statistically significant difference,>0.05.According to the pathogenesis of classification,sudden deafness can be divided into rise type,decline type and consistent type.The pathogenesis of rise type may be different degree of hydrops of inner ear.Decline type may be hair cell damage,and consistent type may be related to the damage of vascular stria and potential labyrinthitis,prognosis is poorer.
