[Application of temporal anterior hairline incision in internal fixation of zygomatic complex fracture].
OBJECTIVE
To investigate the methods, merits and effects of temporal anterior hairline incision in internal fixation of zygomatic complex fracture (ZCF).


METHODS
99 cases of ZCF were treated via vertical incision in temporal anterior hairline. During dissection, the zygomatic branch and the frontal branch of the facial nerve, which crossed over the zygomatic arch, were protected. The deep fascia superficial to the zygomatic arch was horizontally incised, the periosteum was elevated at the fracture sites. Cases of type A1 were treated through the above approach; while minor periorbital and oral vestibule incisions were also used in cases of type B and C. The fracture segments were reduced accurately and fixed with titanium microplates. Coronal incision was not applied in all cases.


RESULTS
The clinical results were good in 99 cases (86.0%). All the temporal anterior hairline incisions healed primarily. The rate of temporary facial paralysis, due to injury of the zygomatic and frontal branch of the facial nerve, was 24.3%; but all recovered six months later, without any permanent paralysis.


CONCLUSIONS
The temporal anterior hairline incision has many merits including clear field of operation, convenient manipulation, minimal trauma, less bleeding, high accuracy of reduction and inconspicuous scar.
