- Abstract
Objective: To explore the characteristics of tympanic cavity pressure and static compliance in different years old children., Method: 302 cases (567 ears) were studied. All cases were divided into five groups according to their age. Their tympanic cavity pressure and static compliance were tested., Result: Most tympanic cavity pressure ranged from +50 to -50 dapa in all groups. The volume of static compliance in group one is the largest (0. 71 ml), and it changed with the age. It gradually decreased from 3 month to 3 years old but increased after three years old until 6 years old then returned to the level in 1 year old., Conclusion: The tympanic cavity pressure and static compliance are relevant to the age when children are small than 6 years. This characteristic must be considered on clinic diagnosis of middle ear disease and the evaluation of hearing.
