Abstract
Aim: This study aimed to evaluate the differences between angle, length and volume of the nasolacrimal canal in unilateral cleft lip and palate patients. Material and Methods: A total of 29 unilateral cleft lip and palate patients (16 female and 13 male) and 58 nasolacrimal canals were examined. Anteroposterior diameter, transverse diameter, length, angle and volume values of the nasolacrimal canal were measured and statistically compared. Results: The mean nasolacrimal canal volume was 619.04±235.55 m3 on noncleft side and 548.63±247.99 m3 on cleft side and significant difference was found. The mean transverse diameter was 4.81±1.29 mm on noncleft side and 4.49±1.18 mm on cleft side and significant difference was found among them. There were no difference among the nasolacrimal canal length and anteroposterior diameter. Conclusion: It can be thought that unilateral cleft lip and palate patients are more likely to have a nasolacrimal system problem on cleft side.
