Thirty-two dacryocystorhinostomies were performed in the chronic dacryocystitis and obstruction of the nasolacrimal duct between 1971 and 1976.
A routine dacryocystography was performed prior to operation in all cases.
A modified Toti´s method was applied as a surgical technique; vaseline gauze was used as a plugging agent and both posterior flaps of sac ans nasal mucous membrane was not sutured because of technical difficuty and for prevention of granulation tissue due to suture materials
Ranging in age from 22 to 66 years of age; 3 were men and 29 were women. Success was achieved in 29 of 32 cases initially.
One of three initial failure cases, which was due to formation of obstructing granulation tissue by suture materials in posterior flap, was turn into success by secondary operation.
We attempted to make this method in 3 cases of shrunken sac: Two were failed. In these cases, if vaseline gauze should removed after more than 10 days, it will be possible to expansion of shrunken sac and to obtained successful result.
We also attempted to make this method in 3 cases of macerted sac, and gained successful result. In such a case, it is possible by suturing of anterior flaps of sac and nasal mucous membrane only. In conclusion, this operation is simple to do and within the range of any ophthalmic surgeon. It is possible in case of macerated sac and shrunken sac.
