Microstructures of the Bony Modiolus in the Human Cochlea: A Scanning Electron Microscopic Study

抄録

The structures of the bony modiolus in the human cochlea were examined by scanning electron microscopy (SEM). The spiral canal for the spiral ganglion and spirally running spaces for the modiolar artery and anterior and posterior spiral veins in the modiolus showed openings or windows leading to the perilymphatic space.
