[The treatment method and effect of orbital floor defects repaired with autologous tragus cartilage through Cald-well-Luc approach under nasal endoscope].

OBJECTIVE

To explore the operative method and effect of fracture of orbital floor defects repaired with tragus cartilage through Cald-well-Luc approach under nasal endoscope.

METHOD: Fifteen cases suffered fracture of orbital floor defects(blow out fracture) were analyzed retrospectively. Oral vestibular incision were done directly to tip teeth kennel, maxillary sinus anterior forewall was chiseled with 2 cm x 2 cm size, orbital floor fracture defect size was probed under nasal endoscope, and the fracture of orbital floor defects was repaired with tragus cartilage.

RESULT: Fifteen cases were successfully operated and no cases showed vision loss,diplopia, enophthalmos obviously after operation,while 3 case were a little eyeball limitation of activity and restored basically after one month. With two years of follow up, there were no spurious eyelid drooping, up-eyelid lacuna deepen, eyelid diameter shorten and facial deformity were found. Both eye-balls were basical symmetry and no complications were happened.

CONCLUSION

It is a satisfactory, effective and aminimally invasive surgical method without facial scars and eyelid ectropion for fracture of orbital floor defects repaired with tragus cartilage through Cald-well-Luc approach under nasal endoscope.
