Investigating the effects of inferior turbinate outfracture on the lacrimal system by evaluating the results of paranasal sinus computed tomography and nasolacrimal irrigation test.

Objectives: This study aims to investigate the effects of inferior turbinate outfracture on the nasolacrimal system and tear flow.

Methods: Forty-seven patients (26 males, 21 females) between the ages 18 and 52 years (mean age-29.0 ± 9.6 years) were included in the study. Preoperative nasal examinations and paranasal sinus computed tomography of the patients were carried out; the direction, location, nasal septum deviation classification and inferior turbinate hypertrophy size classification were evaluated. Lacrimal irrigation test was performed preoperatively and 14 days postoperatively.

Results: The study included 47 patients who underwent septoplasty and inferior turbinate outfracture. The mean duration of lacrimal irrigation test was 2.9 ± 0.8 s on the right side and 3.0 ± 1.1 s on the left side preoperatively, and 2.1 ± 0.8 s on the right side and 2.2 ± 1.0 s on the left side postoperatively. No significant relationship between direction, location classification, angle nasal septum deviation classification and lacrimal irrigation test duration was found. A significant relationship between size classification of the left inferior turbinate and preoperative lacrimal irrigation test duration was noted (p = 0.030). Moreover, a significant decrease between preoperative and postoperative lacrimal irrigation test duration after inferior turbinate outfracture (p = 0.000) was noted.

Conclusion: We concluded that outfracture of the inferior turbinate with septoplasty surgery may benefit the regulation of tear flow. In addition, we concluded that lacrimal irrigation test duration may be effective in determining the patients with subclinical nasolacrimal duct partial obstruction due to inferior turbinate pathologies.
