Fifty-two secretory otitis media (S.O.M.) ears with protracted course were compared roentgenologically (Schuller projection) with 52 S.O.M. ears which recovered after insertion of a single ventilating tube. Measurements were done first by comparing the pneumatised area millimetrically and later semiquantitatively according to the size of the mastoid cells--grading the mastoid cells from 1 (eburnize) to 10 (very big mastoid cells). S.O.M. ears with protracted chronic course showed an average mastoid area of 312 mm2, their cell size showing on the average a diploic or small-diploic cells--corresponding to grade 3.5. On the other hand, S.O.M. ears which recovered promptly had an average mastoid area of 440 mm2, and their mastoid cells began to show as actual cells (small up to medium cells), corresponding to grade 5.7. The difference, both millimetrically and grade-wise, between the two groups was found to be very significant (P greater than or equal to 0.01). We may conclude that the prognosis of S.O.M. is related to the size of their mastoid cells or alternatively to the amount of air in the middle ear cleft as a whole.
对52例病程迁延的分泌性中耳炎（S.O.M.）耳与52例插入单根通气管后痊愈的分泌性中耳炎耳进行了X线（许勒位）比较。首先通过毫米测量法比较气化面积，随后根据乳突气房大小进行半定量——将乳突气房从1级（硬化型）到10级（非常大的乳突气房）进行分级。病程迁延的慢性分泌性中耳炎耳乳突平均面积为312平方毫米，其气房大小平均显示为板障型或小板障型气房——相当于3.5级。另一方面，迅速痊愈的分泌性中耳炎耳乳突平均面积为440平方毫米，其乳突气房开始显示为实际气房（小至中等大小气房），相当于5.7级。发现两组在毫米测量和分级方面的差异均非常显著（P≥0.01）。我们可以得出结论，分泌性中耳炎的预后与其乳突气房大小相关，或者说与整个中耳裂内的空气量相关。
