An ultrasonographic approach for the tympanic bulla in calves is described. Ultrasound evaluation was performed through a lateral approach on 7 fetuses, 2 newborn calves, and 4 living calves of various ages. The probe was positioned caudal to the vertical mandibular ramus, ventral to the base of the ear. Three different positions of the probe were used. The tympanic bulla and adjacent structures were successfully identified and their ultrasonographic appearance described. Fluid within the tympanic bulla was visualized in 12 bullae in the cadavers and in 6 bullae in live calves. Ultrasound imaging has been shown to be useful but its diagnostic value remains to be studied in clinical cases of otitis media in calves.
本文描述了一种用于犊牛鼓泡的超声检查方法。通过外侧入路对7头胎儿、2头新生犊牛和4头不同年龄的活体犊牛进行了超声评估。探头置于垂直下颌支的尾侧、耳基部的腹侧。使用了探头的三种不同位置。成功识别了鼓泡及相邻结构，并描述了它们的超声图像特征。在尸体的12个鼓泡和活体犊牛的6个鼓泡中观察到鼓泡内有液体。超声成像已显示出有用性，但其在犊牛中耳炎临床病例中的诊断价值仍有待研究。
