The evoluation of various types of dacryocystorhinostomies has been reviewed. The indications for operation are discussed. A simplified technique of surgery is illustrated and described in detail. The advantages of the method are: (1) The elimination of elaborate methods to remove the lacrimal bone while preserving the nasal mucosa. (2) The avoidance of the necessity of suturing the nasal mucosa membrane to the sac flaps. (3) The use of a comfortable, inconspicuous, easily inserted and easily removed silicone sponge stent to help avoid closure of the osteotomy.
