Observation of Nasal Septal Deviation in Patients with Unilateral Chronic Dacryocys-titis
OBJECTIVE To observe the nasal septal deviation in patients with unilateral chronic dacryocystitis using lacrimal duct computed tomography(CT)imaging.METHODS A total of 181 patients diagnosed with unilateral chronic dacryocystitis from July 2019 to February 2021 at Hospital of Chengdu University of Traditional Chinese Medicine were included.All patients underwent lacrimal duct computed tomography(CT)imaging upon admission to assess nasal septal deviation and measure the vertical distance from the top and bottom of the lacrimal sac to the nasal septum.RESULTS(1)Nasal septal deviation:Among the patients,140 cases(77.35%)exhibited nasal septal deviation,with 113 cases(80.71%)deviating toward the affected side and 27 cases(19.29%)deviating toward the healthy side.(2)Analysis of vertical distances from the top and bottom of the lacrimal sac to the nasal septum:The mean vertical distance from the top of the lacrimal sac to the nasal septum on the affected side was lower than that on the healthy side,with statistically significant differences(t=-9.293,P=0.000).Similarly,the mean vertical distance from the bottom of the lacrimal sac to the nasal septum on the affected side was lower than that on the healthy side,with statistically significant differences(t=-9.238,P=0.000).CONCLUSIONS This study revealed that unilateral chronic dacryocystitis is more common in middle-aged and elderly female patients and is often accompanied by nasal septal deviation.Additionally,the vertical distance from the lacrimal sac to the nasal septum on the affected side is smaller than that on the healthy side.
