Purpose. To develop a delicate method of dacryorhinostomy formation during endoscopic dacryocystorhinostomy (DCR) based on modern less traumatic techniques allowing better results with lower complications rate. Material and methods. Surgical treatment of patients suffering from chronic dacryocystitis with nasolacrimal duct obstruction was performed. Nasolacrimal anastomosis formation was performed using modern energy methods during steps of endoscopic DCR. Totally, 16 patients were treated, ten females and six males. Mean age was 67 years. Mean follow-up period was 6 months. Results. In all patients an adequate nasolacrimal anastomosis was formed. During surgery there was no one case of damage to the lateral wall of the lacrimal sac (LS) or significant intra- and postoperative bleeding. Functional success was marked in 93.75% (15/16) of cases. In 6.25% (1/16) there was a postoperative granuloma in the rhinostomy region which prevented tear passage. Conclusion. A combination of controlled low-temperature ablation of nasal mucous, ultrasound bone destruction and laser dissection of the medial wall of the LS allows creation of an adequate nasolacrimal anastomosis, makes surgery significantly quicker and easier, enables better soft tissues healing in shorter terms.
