This study revealed that fractures of the bony nasal pyramid may heal by osteogenesis. Fibrous union and partial bone resorption may occur, especially where there is isolation of fragments by soft tissue. The nasal process of the maxilla was the most frequent site of such fibrous healing. Cartilaginous fractures healed by fibrous union in all cases.
