Oral SurgeryThe temporal fossa is located on the side of the skull, above the zygomatic arch and lateral to the orbit. The Gillies approach involves an incision in the temporal region to access the zygomatic bone, which is then manipulated to reduce the fracture and restore its normal anatomical position. This approach is commonly used in oral and maxillofacial surgery for the management of complex zygomatic fractures.
