Final answer:
Grossly comminuted mandibular fractures usually require open reduction, where an incision is made to directly manipulate and realign the fractured bone fragments. Surgical fixation methods may be used to stabilize the fracture.
Step-by-step explanation:
Mandibular fractures that are grossly comminuted, meaning that the bone is shattered into multiple fragments, often require open reduction to realign the bone pieces.
Open reduction involves making an incision to directly visualize and manipulate the fractured bone fragments. Surgical fixation methods such as the use of plates, screws, or wires may be used to stabilize the fracture and promote proper healing.
