Abstract
The invention relates to a device for ventilating the middle ear by means of a ventilation tube which is made of a tissue-compatible material, preferably titanium, and with a through-channel for air communication between the cavity of the middle ear and the outside air. The ventilation tube comprises, on the one hand, a front portion (2) which is arranged to be introduced into bone tissue and is designed so that a permanent anchoring is obtained in the bone tissue, and, on the other hand, a rear portion (6) which forms a passage through the skin. The ventilation tube further comprises an outer tube (1) which is made of the said tissue-compatible material and an inner tube (8) which is arranged releasably in the outer tube and whose inner bore forms the said through-channel (14) for air communication between the cavity of the middle ear and the outside air.
