We investigated the relationship between the Eustachian tube's ventilatory function and the pneumatization of mastoid air cells. In 65 adults (66 ears) with chronic otitis media (COM), ventilatory Eustachian tubal function was evaluated by the inflation-deflation test, while the area of mastoid air cells was measured by the rectangular method on X-ray film. Group I represents good function in both the inflation and deflation tests. Group II represents good function in the inflation test but poor function in the deflation test. Group III represents a poorly functioning Eustachian tube in both tests. The opening pressure in Group III was statistically higher than in Group I and Group II. The area of mastoid air cells in Group I was statistically larger than in Group III. There was no correlation between opening pressure and area of mastoid air cells in COM. Postoperative failure of the tympanic membrane was frequently found in Group III. We discuss the tubal function and pneumatization of mastoid air cells.
我们研究了咽鼓管通气功能与乳突气房气化之间的关系。在65例患有慢性中耳炎（COM）的成年人（66耳）中，通过充气-放气试验评估咽鼓管的通气功能，同时在X线片上用矩形法测量乳突气房的面积。第一组在充气和放气试验中均表现为功能良好。第二组在充气试验中功能良好，但在放气试验中功能较差。第三组在两项试验中均表现为咽鼓管功能不良。第三组的开放压力在统计学上高于第一组和第二组。第一组乳突气房的面积在统计学上大于第三组。在慢性中耳炎中，开放压力与乳突气房面积之间无相关性。第三组中鼓膜术后失败的情况较为常见。我们讨论了咽鼓管功能和乳突气房的气化。
