Dimensions of importance in reconstructive middle ear surgery. 1977

A Tjellström

A study of the space available for an ossicular prosthesis is presented. Twelve temporal bones without any signs of chronic ear disease were used. The measurements were made with the bone free from soft tissue mounted on a microscope cross-table. The different distances were registered through a stereo-microscope. The width between the facial nerve canal and the promotory was found to be 2.2 mm. The distance from the footplate to the tympanic sulcus plane was found to be 6.6 mm. The space available for the head of a prosthesis was also investigated.

D013701 Temporal Bone Either of a pair of compound bones forming the lateral (left and right) surfaces and base of the skull which contains the organs of hearing. It is a large bone formed by the fusion of parts: the squamous (the flattened anterior-superior part), the tympanic (the curved anterior-inferior part), the mastoid (the irregular posterior portion), and the petrous (the part at the base of the skull).

D019736 Prostheses and Implants Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
