The study and application of the three dimensional anatomical atlas of temporal bone / 解放军医学杂志

ABSTRACT

Objective Celloidin sections of temporal bone were used to develop a serial stereo anatomical atlas of temporal bone by computer aided three dimensional(3-D) reconstruction and stereology. Methods Fifty sets of serial celloidin sections of temporal bone with reference points were prepared and 3-D morphology of structures in temporal bone was restored systemically by the technique of computer aided 3-D reconstruction. A system of stereo anatomical atlas of temporal bone with stereoscope was established. Results Totally 48 cases of reconstruction were accomplished for bony and membranous labyrinth, ossicles, tendons, facial nerve and its canal, round window membrane and niche, posterior ampullary nerve, endolymphatic sac, cochlear aqueduct, VII and VIIIth cranial nerve. The stereo picture pairs of these structures with the best representation were selected as the stereo anatomical atlas of temporal bone which showed the fine spatial morphology and relationship of the above structures. The stereo anatomical atlas was applied to guide ear surgery and to assist anatomic training of temporal bone. Conclusion The stereo anatomic atlas of temporal bone is an innovative powerful anatomic tool and has tremendous application futures in otology, or even in the whole medical science.
