Primary Endoscopic Dacryocystorhinostomy

Abstract

Endoscopic endonasal dacryocystorhinostomy has gained considerable popularity in the recent two decades with the advent of the rigid fiber-optic endoscope and its use in paranasal sinus surgery. It avoids a facial incision, disruption of the medial canthal tendon, injury to the terminal branch of facial nerve, or a full-thickness (skin to mucosa) ring contracture over the osteotomy site and in addition is not contraindicated during active dacryocystitis. This chapter discusses the indications, goals, and simple techniques for a successful outcome of an endoscopic DCR.
