It has been widely accepted that a split of the deep temporal fascia occurs approximately 2 to 3 cm above the zygomatic arch, named the superficial and deep layers. The deep layer of the deep temporal fascia lies between superficial temporal fat pad and the temporal muscle. However, during the investigators' previous surgeries, the investigators did not find the deep layer of the deep temporal fascia between superficial temporal fat pad and the temporal muscle. This study was conducted to clarify the presence or absence of the deep layer of the deep temporal fascia. And the investigators' clinical study has confirmed the absence of the deep layer of the deep temporal fascia between superficial temporal fat pad and the temporal muscle.
The anatomic layers of soft tissues of the temporal region, with regard to the deep temporalis fascia, was investigated in 169 cases operated upon with zygomaticofacial or craniofacial fractures using the supratemporalis approach from June 2013 to June 2017. Among 167 surgeries, this so-called "deep layer of the deep temporalis fascia" was not observed. In fact, the superficial temporal fat pad is closely attached to temporal muscle above the zygomatic arch.
253 studies on the registry are indexed under Craniocerebral Trauma; 45 are open to participants now.
This study's enrollment of 167 is close to the median of 180 across 111 observational studies indexed under Craniocerebral Trauma.

Clinical and imaging diagnosis of zygomaticofacial or craniofacial fractures A need to operate using the supratemporalis approach No previously surgical treatment
Exclusion Criteria:
unobvious displaced fracture disagree with the surgical treatment previous unsuccessful surgery at the temporal region
patients operated upon with zygomaticofacial or craniofacial fractures using the supratemporalis approach
Procedure: The supratemporalis approach
The incision differs according to specific fracture sites. It can be a hockey stick-shaped incision, hemicoronal incision, and full coronal incision. The first layer of dissection was just under the superficial temporalis fascia.Then, approximately at the level of 3-5cm above the zygomatic arch, our modified incision was carried through the deep temporalis fascia.Next, the superficial fat pad was encountered and retracted anteriorly, which was in close contact of the temporal muscle. Finally, a flap that included skin, subcutaneous tissue, the superficial temporal fascia, the areolar fat tissue, the deep temporalis fascia and the superficial temporal fat was reflected as a whole anteriorly, fully exposing the temporal muscle and zygomatic arch.

Ran from Jun 2013 to primary completion in Jun 2017, 47 months.
Of 43 non-industry observational studies under Craniocerebral Trauma, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 49. This study's 47 months is above that.
Counting every sponsor, half of 43 studies reached it within 32 months; a quarter within 15 and three quarters within 49.
