Abstract

Distribution and calibre of capillaries in the middle and inner ears were observed on 48 rabbits after intravascular injection with India ink.<br>The conclusions summarized were as follows:<br>1) The major blood vessels supplying the malleus and the incus coursed on the. ligaments attached to both ossicles.<br>2) The calibre of capillaries (arteriole, nets capillary and venule) in subepithelial layer of the inner ear was smaller than those of the middle ear wall.<br>3) The crista acustica, the macula acustica and the stria vascularis had dense capillary network, while the semicircular canal, the vestibule except neuroepithelial areas and the round window had particular loose network.<br>4) The intermediate zone of the drum had a broad area without blood vessels.<br>5) In the crista acustica, the macula acustica, the stria vascularis, the eustachian tube and the auditory canal, the ratio of maximal size and minimal size of superficial capillary nets was generally large, while in the tympanic cavity, the ratio was generally small.<br>6) In the outer epidermal layer of the drum, peculiar form of blood vessel distribution was seen-capillaries on the border of mesh of blood vessels were forming elliptical loops.<br>7) The capillary nets in the spiral ganglion were winding, but could not be called as glomus.<br>8) In most animals, Reissner's membrane had fine blood vessels.<br>9) There was close anastomosis of blood vessels between the external ear and the middle ear.<br>10) Between the inner ear and the middle ear, there was no communicatin of blood vessels.<br>11) In the stria vascularis, anastomosis was not seen except arterioles and venules.
