Nasoethmoid complex injuries.

Blunt and penetrating trauma to the nasoethmoid complex can present a challenge to reconstruction by the facial trauma surgeon. Both functional and cosmetic problems exist with these injuries and both must be considered in the surgical plan. Adequate preoperative physical examination and roentgenologic evaluation, coupled with a thorough ophthalmologic consultation, are required for complete knowledge of the extent of the damage. The surgical repair of nasoethmoid fractures involving the medial canthal tendon and lacrimal drainage system should be repaired primarily. A medial blow-out fracture of the orbit is uncommon but should be considered in all cases of severe nasoethmoid complex fractures.
