Abstract
- Medial blowout fracture with persistent diplopia and enophthalmos was required surgical treatment. Conventionally, surgery of blowout fracture of the medial wall has been performed by the transorbital approach with external incision. The conventional method had some disadvantages of external scar, increased morbidity, and general anesthesia. We performed endoscopic endonasal surgery without external incision in 2 cases of medial blowout fracture under local anesthesia. The bony fragments were removed after the intranasal ethmoidectomy. And the entrapped medial rectus muscle was released from the bony fragments. Merocel(R) was placed in the ethmoid sinus for the support of the orbital defect for 48 hours. Results of the surgery in all 2 cases were satisfactory and there were no evidences of diplopia and enophthalmos so far.
