Modified technique for endoscopic endonasal reduction of medial orbital wall fracture using an absorbable packing

Abstract

Purpose

The purpose of this study was to describe a modified technique using only biological dura substitute (Lyoplant®) associated or not to a sheet of Medpore® (porous polyethylene plate) avoiding the use of Silastic® or Merocel® packing for endoscopic endonasal reduction of medial orbital wall fracture.

Methods

An interventional case report was used involving two patients with medial orbital wall fracture that were treated with the modified technique. Postoperatively, the patients were evaluated for visual acuity, enophthalmos, extraocular motility, and diplopia.

Result

Twelve months after surgery, patients recovered completely without any residual eye symptoms or complications, and postoperative CT showed a completely corrected medial orbital wall fractures.

Conclusion

The reported technique proved itself to be safe and effective, and it may be expected to have advantages over the conventional endoscopic approach using a non-absorbable packing, avoiding the need for long-term nasal packing and a secondary removal procedure.
