Abstract:
Objective To propose a new classification scheme of otitis media (OM). Methods By reviewing current internat ional classification systems of OM, we analyzed their disadvantages and the prog ress made in histopathologic studies of OM, then worked out a new classification scheme to apply it to clinic. Results In current internati onal classification systems of OM, those apparent clinical signs are regarded as main standards of classification. Their main disadvantage is that these signs c annot very well indicate the condition of pathologic and functional changes of i mportant hearing structure areas. We proposed a “Three-stage Scheme” of OM cl assification and applied in 1 160 cases of OM. The accuracy rate of diagnosis w as 82.4% in 348 cases of early-stage OM, 98.4% in 696 cases of chronic OM, and 95.2% in 116 cases of OM sequela. Conclusion The “Three-s tage Scheme” system is scientific, simple and practical. Its accuracy rate of d iagnosis is very high. It plays a guiding role in diagnosis and treatment of OM.
