慢性化脓性中耳炎(以下简作OMPC)系中耳间隙(鼓室、上鼓室、咽鼓管、鼓窦及乳突气房)长期不愈的炎症。Proctor(1973)根据病情发展情况将其分为:活动期、非活动期、静止期及痊愈期四期;根据需否急诊手术又可分为恶性危险型和良性安全型二型。Mawson(1963)称区别上述二型,在于发生学上的胚胎构型不同,即纤毛柱状上皮的慢性炎症很少侵及其所覆盖下方的骨质,只局限在粘膜层;而上鼓室及鼓窦处扁平上皮的慢性炎症则可侵及其覆盖下方的骨质。此二型可分别存在,亦可兼有。良性安全型又名“管鼓室炎”(tubotympanitis),此型相当于LillieⅠ及Ⅱ型,如有上皮内生形成继发性胆脂瘤则属LillieⅢ型。【影响OMPC治愈的因素】OMPC的治
Chronic suppurative otitis media (hereinafter referred to as OMPC) is a long-term unhealed inflammation of the middle ear space (tympanic cavity, upper tympanic cavity, eustachian tube, mastoid sinus and mastoid gas space). Proctor (1973) according to the condition of the disease will be divided into: active, inactive, quiescent and recovery of four; according to the need for emergency surgery can be divided into two types of malignant and benign type safety. Mawson (1963) said the difference between the above two types, is the occurrence of the embryonic configuration is different, that is, chronic inflammation of the ciliated columnar epithelium rarely infiltrates under the cover of the bone, is confined to the mucosal layer; the upper tympanic and drum Chronic inflammation of the flattened epithelium of the sinuses can invade the underlying bone mass. The two types can exist separately, or both. The benign and safe type, also known as “tubotympanitis” (tubotympanitis), this type is equivalent to Lillie Ⅰ and Ⅱ type, if the formation of secondary epithelioid cholesteatoma is Lillie Ⅲ type.
