儿童腺样体肥大与分泌性中耳炎的关系

【目的】探讨腺样体的形态和大小与分泌性中耳炎（SOM）的相关性。【方法】手术中根据腺样体与咽鼓管圆枕间接触的紧密程度，将腺样体的形态依次分为四组，分析各种分型在伴s0M和不伴SOM的患儿中的差异；并根据腺样体肥大的程度，将138例患儿分为腺样体中度肥大组和病理性肥大组，分析腺样体肥大程度对中耳功能的影响及两组间SOM发病率的差异。【结果】在有无SOM方面，无压迫型的腺样体形态具有极显著性差异，而挤压型、紧贴型、混合型的腺样体形态组间的差异均不显著（P〉0．05）；病理性肥大组中SOM的发病率明显高于中度肥大组，组间具有显著性差异（P〈0．05）。【结论】腺样体的形态和肥大程度与SOM发病率有密切关系。

Relationship Between Adenoidal Hypertrophy and Secretory Otitis Media in Children

[Objective] To explore the relationship between the shape of adenoids and secretory otitis media（SOM）. [Methods] According to the compactness of adenoids in touch with torus tubarius during the operation, adenoids were categorized into 4 groups. The difference of various types of adenoids between children with and without SOM was analyzed. According to the grades of adenoid hypertrophy, 138 children were divided into moderate adenoid hypertrophy group and pathological adenoid hypertrophy group. The effect of the grades of adenoid hypertrophy on middle ear function and the difference of the incidence of SOM were analyzed. [Results] There was significant difference in the shape of adenoids without oppression group between the children with and without SOM, but there was no significant difference in the shape of adenoids with oppression, tightness or mixture between the children with and without SOM（ P〉0.05）. The incidence of SOM in pathological adenoid hypertrophy group was obviously higher than that in moderate hypertrophy group, and there was significant difference among groups（ P〈0.05）. [Conclusion] The shape and hypertrophy of adenoid are closely related with the incidence of SOM.
