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.
对全聋型和突聋平坦型进行重新分类，明确新分类与听力预后的关系。分析192例突聋患者，尤其对159例平坦型和全聋型患者进一步进行曲线类型分类，分为上升型、下降型和一致型，采用回归分析在多因素中分析与听力有关的可能因素。按年龄分组45岁，>0.05，差异无统计学意义；按病程分组0 - 7天和14天以上，<0.01，=4.291；8 - 14天和14天，<0.05，=2.983；按平坦型和全聋型分组，<0.05，=0.409；按耳聋曲线类型，上升型与全聋型差异有统计学意义，<0.01，=9.692；下降型、一致型与全聋型相比，差异无统计学意义，>0.05。根据发病机制分类，突聋可分为上升型、下降型和一致型。上升型发病机制可能为不同程度的内耳积水。下降型可能为毛细胞损伤，一致型可能与血管纹损伤及潜在迷路炎有关，预后较差。
