Aim:
The value of a complex endonasal microsurgical treatment of lacrimal duct stenosis.
Material And Methods:
in a group of 418 patients we performed 455 dacryocystorhinostomy (DCR) including 37 bilaterally. They were 263 females (62.9%) and 155 males (37.1%). Age ranged from 1.5 to 87, mean age 54.3 years. Performance: general anaesthesia with controlled hypothension, semi sitting position of patient and adjustable headrest, operating microscope (300 mm lens). Operative procedure: septum mobilization and anterior ethmoidectomy, dacryocystorhinostomy (DCR).
Results:
satisfactory results were obtained in 436 of cases (95.8%), 19 no change (4.2%). Only 18 cases received a prosthesis. There were only 2 complications (0.2) not serious.
Conclusion:
endonasal microscopic dacryocystorhinostomy preserves intact bony support and frame of lacrimal ducts and the nasal function of the lacrimal pump. It allows simultaneous management of the concomitant sino-nasal pathology as well as shorter operation times, lower complication rates and reduced patient morbidity.
