[Prosthetic treatment of blow-out fracture in medial orbital wall with nasoseptal cartilage under nasal endoscope].
OBJECTIVE
To study the clinical effect of Treatment of blow-out fracture of medial orbital wall with nasoseptal cartilage under nasal endoscope.


METHODS
Under a nasal endoscope, the fracture and the prolapsed orbital contents were reduced to the orbit, and then an autogenous nasoseptal cartilage was grafted into the orbital defect. The variations in the visual acuity, diplopia, enophthalmos degree and eyeball position were detected preoperatively and postoperatively.


RESULTS
During the follow up of three months to four years after operation, all the 28 cases showed neither loss nor distinct descent of visual acuity. The postoperative mean enophthalmos degree (1.5 +/- 0.6) mm was lower than the preoperation one(3.6 +/- 1.1) mm (P<0.05). Diplopia disappeared completely of 25 cases during 3 month after operation,while it appeared in the primary position of 2 cases. The eye movement was normal of 26 cases after operation t, and the abduction was slightly limited of 2 cases, but which was better than be for). Any displacement of filling material, infection, rejection reaction were not found of all the 28 cases.


CONCLUSIONS
The medial orbital blow out fracture with nasal endoscope has many advantages, such as short operative route, clear surgical visual field, simple performance, light injury and no scars, and the effect of which will be really certain in the operative practice.
