Abstract: To provide a detailed anatomic data of temporal region and evaluate the clinical application of intermedial temporal space in re-time bone graft operation. MethodsStepwise dissection was performed in the temporal region in 15 pre-fixed adult cadavers(30 sides) with the aid of surgical microscope，and the anatomic layers，the distribution of nerves and blood vessels in temporal region were observed. Results① Temporal region was rich in fascia layers，fatty tissue layers, and contained 3 latent anatomic spaces；② The distance between point A,B and dorsal root of ygomatic arch was 0.3-0.85 cm［（0.5±0.1）cm］,2.2-3.5 cm ［（2.6±0.3）cm］, respectively. ③ All of the temporal branches of facial nerve were located in front of line CD，75.0% in subcutaneous tissue, 21.4% in superficial temporal space, 3.6% in intermedial temporal space. Conclusion ① The intermediate fat layer is an important landmark of intermediate temporal space;② The skin flap before dorsal root of ygomatic arch 1 cm is safety to temporal artery;③ The temporal space after the line CD is a safety operation area for the protection of temporal branch of facial nerve.
