Osteotomy in 3D – A Comprehensive Guide to Surgical Technique and Anatomical Safety in Dacryocystorhinostomy (DCR) (2023) Ahmed Mahmoud Amin

Description

This text details the critical 3D considerations for performing osteotomy during Dacryocystorhinostomy (DCR) surgery. It covers surgical rationale, requirements for an ideal osteotomy (site and size), essential surgical tools (Kerrison, drills, Piezo surgery), and meticulous steps for execution. A major focus is placed on recognizing and avoiding catastrophic anatomical relations (including the anterior ethmoidal artery and potential CSF leak) and managing complications like Sump syndrome. The document also provides guidance on when and how to perform ethmoidectomy.
