Transnasal endoscopic dacryocystorhinostomy is a good alternative for external DCR. It is considered a safe and efficient technique with successful results, comparable or even better than the external technique. Advanced knowledge of the endoscopic anatomy and the lacrimal system is necessary to perform the procedure safely, and to obtain good surgical outcomes. The aim of the paper is to analyze the changes of the endoscopic technique and to improve it. The transnasal endoscopic dacryocystorhinostomy surgical technique is described in a "step by step" manner. Also the surgical technologies that can be used for this intervention are presented, focusing on the cold instruments.

Transnasal endoscopic orbital decompression is a viable alternative for external orbital decompression. Today, it can be performed due to the great development of endoscopic technology and specific endoscopic surgical instruments. It requires strong anatomic knowledge and skilled hands. We present our experience with endoscopic orbital decompression focusing on the surgical technique used in our department. The surgical maneuvers must be firm and gentle protecting the local risk elements and respecting the orbital content.
