Approach of the zygoma complex factures through the zig-zag coronal incision with postauricular extension

초록

The ideal surgical approach to treat craniomaxillofacial fractures should provide maximum exposure of the fractured segments, ensure less potential for injury to facial structures, and allow for good cosmetic results. The most frequently used approach is the coronal incision. However, the coronal approach poses some disadvantages. The most common complication is widening of the scar at the head. The inevitable scar, whether narrow or wide, produce a natural separation of the hair. Also, hairline recession may expose the scar above the level of the ear and preauricular sensory deficits and motor deficits involving the frontal branch of the facial nerve have been reported. In order to avoid above problems, we have used zig-zag coronal incision with a postauricular extension from September, 1996 to May, 1998 in 35 cases with diagnosis varying from zygoma complex fracture to extensive facial fracture. Clinical follow-up ranged from 2 to 22 months. In our series of 35 patients, one patient had hematoma, one patient transient weakness of the frontalis muscle and one patient had sensory deficit. We found that this approach maintains the advantages of lowering the pivot point but also lessens the disadvantages of an anterior incision and unlike the straight-line coronal incision, this incision line is immediately much less visible.
