The transmaxillary endoscopic approach to the inferior part of the orbit: How I do it
- 262 Downloads
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.
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.
Intraorbital pathologies located in the inferior retrobulbar space can be successfully operated on using the transmaxillary endoscopic approach.

Video demonstrates essential stages of two bi-portal endoscopic procedures with basic clinical data of the patients. In the first patient the lower orbit was approached through the canine fossa and transnasal antrostomy, in the second patient through antrostomy using the bi-nostril approach (MPG 23621 kb)
