Description
Summary:Background Transmaxillary endoscopic approach to the inferior part of the orbit was demonstrated on cadaveric preparations; however, its clinical application has not been reported. We describe a clinically useful technique of the transmaxillary approach to the lower orbit. Methods A four-hand technique is essential for extensive preparation within the orbit; therefore, the tools have to be introduced into the maxillary sinus through two ports: either through the canine fossa and antrostomy or through antrostomy using the bi-nostril transseptal approach. Conclusion Intraorbital pathologies located in the inferior retrobulbar space can be successfully operated on using the transmaxillary endoscopic approach.
