Abstract
Dacryocystorhinostomy (DCR) is done to bypass obstruction of the nasolacrimal duct i.e. distal to the lacrimal sac, to reestablish drainage of tears into the nasal cavity. It involves removing the bone between the lacrimal sac and the nasal cavity and anastomosing the mucosa of the lacrimal sac to the nasal mucosa (Figure 1). The operation can be done either by external or endoscopic approach with success rates of >90% for both techniques. This chapter describes the external approach.
