[Eighteen cases of plerosising intra-orbital wall blow-out fracture with the nasal septal cartilage under the endoscopic transnasal].

Objective: To investigate the surgical method of plerosising intra-orbital wall blow-out fracture through ethmoid sinuses under trans-nasal endoscopy with the graft of nasal septal cartilage.

Method: Eighteen patients who encounter the intra-orbital wall blow-out fracture were plerosised under trans-nasal endoscopy through ethmoid sinuses. As a part of the surgical method, the nasal septal cartilage was taken as the graft.
