制备并研究了出生后 0、3、7、10 和 14 天袋鼠大鼠的连续组织学切片。出生时，中耳大部分充满间质，尺寸较小，只有一个很小的下鼓室和一个很小的上鼓室隐窝。在出生后的前两周，成人中耳的大部分肥大都会发生。由于内鼓元件从未形成，因此先前称为内鼓室的此处更名为下鼓室。上鼓室隐窝极大地扩张，形成所谓的背（或前）乳突窦。由于该室与乳突无关，因此此处将其重新命名为上鼓室。后面，以前称为后乳突窦从下鼓室生长进入并超出后半规管和水平半规管区域。在发育和成年位置上，它与灵长类动物的窦相当，因此这里被重新命名为窦。
Serial histological sections of kangaroo rats of postnatal ages 0‐, 3‐, 7‐, 10‐, and 14‐days were prepared and studied. At birth the middle ear is mostly filled with mesenchyme and small in size, having only a small hypotympanum and a very small epitympanic recess. During the first postnatal two weeks, much of the hypertrophy found in the adult middle ear develops. Because an entotympanic element is never formed, the previously called entotympanic chamber is here renamed the hypotympanum. The epitympanic recess greatly expands to form what has been called the dorsal (or anterior) mastoid sinus. Since this chamber has no relation to the mastoid, it is here renamed the epitympanum. Posteriorly, the previously called posterior mastoid sinus develops from the growth of the hypotympanum into and beyond the region of the posterior and horizontal semicircular canals. In development and adult position it is comparable to the primate antrum and so is here renamed the antrum.
