Brief Summary

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.

Conditions

Anatomy; Temporal Region Trauma

Deep temporal fascia; Deep layer of the deep temporal fascia; Superficial layer of the deep temporal fascia; Temporal fascial layers; Temporal anatomy

Outcome Measures

Primary Outcomes (1)

• deep layer of the deep temporal fascia

  the investigators did not find the deep layer of the deep temporal fascia between superficial temporal fat pad and the temporal muscle

  during surgery

Study Arms (1)

the supratemporalis approach

patients operated upon with zygomaticofacial or craniofacial fractures using the supratemporalis approach

Procedure: The supratemporalis approach

Interventions

The supratemporalis approach PROCEDURE

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.
