Treatment of infraorbital paresthesia by external decompression in zygomatic complex fractures;Report of 4 cases

This is a report of 4 case of external decompression about infraorbital paresthesia with transconjuctival incision in zygomatic complex fratures. The results are as follows. 1. Decompression for infraorbital nerve injury is indicated if paresthesia exists 5-7 days, although the patients have nondisplaced fractures of zygomatic complex. 2. Satisfactory results are expected within 1-2 weeks after surgical operation in early decompression of infraorbital nerve. 3. Paresthesia of the infraorbital nerve following fracture of the zygomatic complex may be persistent complication. 4. Scar tissues on the face are avoided with transconjuctival approach.
