目的探讨乳突气化情况对成人分泌性中耳炎预后的影响。方法对１２４例（１９４耳）成人分泌性中耳炎乳突气化状况摄乳突Ｓｃｈｕｌｅｒ片，用Ｄｉａｍａｎｔ法测量并计算Ｘ线上显示的乳突的几何学面积。结果１９４耳中气化良好型（面积≥６ｃｍ２）５１耳（２６．３％），１０耳（１９．６％）预后不良；气化不良型（面积＜６ｃｍ２）１４３耳（７３．７％），预后不良７２耳（５０．３％）。结论认为乳突气化不良是影响分泌性中耳炎预后不良的因素之一。
Objective To investigate the influence of mastoid gasification on the prognosis of adult otitis media with effusion. Methods The mastoid Schuler films of 124 cases (194 ears) of adult secretory otitis media were measured. Diamant method was used to calculate and calculate the geometric area of papillae. Results 194 ears (26.3%) had good gasification (area≥6cm2), and 10 ears (19.6%) had poor prognosis. 143 (73.7%) had poor gasification (area <6cm2) , Poor prognosis of 72 ears (50.3%). Conclusion Mastoid gasification is one of the factors that affect the prognosis of secretory otitis media.
