Background and Objectives : Before the introduction of transnasal endoscopic sinus surgery, transorbital approach with an external incision used to be one of the representative reconstructive surgical repairing method of blow out fracture. The important advantages of transnasal endoscopic technique are magnified direct visualization and easy accessibility to the medial orbital wall. Nasopore Forte® is a slowly absorbable material and provides excellent durability. The purpose of this study is to evaluate outcomes of endoscopic endonasal reduction (EER) of medial blow out fracture using Nasopore Forte®.
Subjects and Method : A retrospective study was performed on 26 patients with medial blowout fracture who had undergone EER using Nasopore Forte® from January to December of 2010 at our clinic. A review of medical records included demographic data, preoperative ocular symptoms and signs, and surgical outcomes including postoperative symptom improvement and complications.
Results: Of 26 patients, 5 had persistent diplopia, 5 enophthalmos, and 3 both diplopia and enophthalmos preoperatively. Seventeen patients were asymptomatic, but had large defects with the mean defect size of 2.4 cm2. Postoperative computed tomography scan showed excellent (22) to good (4) reduction. Preoperative symptoms were resolved in all of 13 symptomatic patients and there was no enophthalmos during the follow-up period. No significant complications including sinusitis or synechia were found.
Conclusion: EER is a highly effective and safe procedure for the reduction of medial blow out fracture. Nasopore Forte® is easy to handle and can be tailored to individual defects, and is useful for securing the reduction and preventing adhesion after EER.
