Abstract
Objective: In recent years, we developed a more minimally invasive technique of endoscopic transnasal approach to repair orbital floor fractures (OFF) with preserving and repositioning the fractured bones. This study reviews our technique of endoscopic transnasal approach to OFF patients.
Method: OFF patients treated with endoscopic transnasal approach were reviewed in a retrospective fashion. Type of fracture, locations, period from injury to surgery, surgical outcomes including patient’s subjective symptom and objective examinations, and complications were collected from patient charts. Preoperative and postoperative (>6 months) CT scans were also evaluated.
Results: A total of 5 patients were treated with endoscopic transnasal approach. The subjective symptoms were recovered in all patients. Hess screen test showed no limitation of eye movement after surgery. Postoperative CT scan also showed that the fractured bone of the orbital floor was identified in the almost original anatomic location 6 months after surgery. No complications or bone absorption were found after surgery.
Conclusion: The novel technique of endoscopic transnasal approach to OFF patients resulted in excellent outcomes. It allows more minimally invasive surgery for the patients without any incisions and graft placement. We still have to watch for late complications and the presence/absence of the fractured bone absorption.
