Abstract:
Aim: The aim of this study was to evaluate the effect of concha bullosa (CB) and nasal septal deviation (NSD) on the diameter
nasolacrimal duct (NLD).
Material and Methods: A total of 103 patients who underwent paranasal sinus (PNS) computed tomography (CT) between January
2018 and May 2018 were included in the study. Coronary and axial CT images of the patients were evaluated for the presence of
CB and NSD. Left and right NLD diameters were measured from axial CT plane. To ensure standardization, the NLD diameters
measurement was performed from the CT sections at the level of the inferior border of bilateral bulbusoculi in all patients. The
relationship between the CB, NSD and NLD was statistically analyzed.
Results: Of the 103 patients included in the study, 51 (49.5%) were males and 52 (50.5%) were females. The minimum age of the
patients was 18 years, the maximum age was 79 years and the median age was 38 years. Forty patients (38.8%) had CB and 63
patients (61.2%) had no CB. Nasal septum was in the midline in 39 patients (37.9%) and NSD was present in 64 patients (62.1%). The
median NLD diameter was 5.8 mm on the right and left side. NLD diameter was significantly smaller in females than males(p<0.05).
There was no statistically significant relationship between CB, NSD and the NLD diameter.
Conclusion: In our study, there was no significant effect of the presence of concha bullosa and nasal septum deviation on the
nasolacrimal duct diameter
