Dacryocystorhinostomy

Dacryocystorhinostomy is the formation of a fistula between the lacrimal sac and the nasal cavity. At present, the operation of the dacryocystorhinostomy almost completely replaced the extirpation (removal) of the lacrimal sac. The main advantage of dacryocystorhinostomy is in maintaining the function of lacrimation. The indication for dacryocystorhinostomy is chronic dacryocystitis, acute dacryocystitis at the stage of subsiding, dilation (ectasia) and lacrimal sac fistula.
