The cleft lip/palate (CLP) deformity negatively affects the anatomy of the nasal cavity and maxilla. The effects of this deformity on the lacrimal system have been unidentified yet. This study aimed to evaluate the morphometric changes in the nasolacrimal duct using cone-beam computed tomography (CBCT) in patients with unilateral CLP.
Retrospective bilateral measurements of the narrowest transversal diameters and the lengths of the nasolacrimal ducts were made for the affected and unaffected sides of 28 patients with CLP and 28 control patients, using the CBCT images. The measurements were statistically compared.
The mean narrowest transversal diameter of the nasolacrimal duct for the affected side of the patients with unilateral CLP was statistically significantly narrower than the unaffected side (P = 0.01). There were no statistically significant differences between the control group and the affected and unaffected sides of patient group with unilateral CLP regarding the nasolacrimal duct diameter. The differences were not statistically significant among all groups regarding the mean nasolacrimal duct length.
The diameter of the nasolacrimal duct at the affected side of unilateral CLP was narrower than the unaffected side. According to this result, the CLP deformity can have an effect on the nasolacrimal duct diameter. However, CLP might not affect the nasolacrimal duct length.
唇腭裂（CLP）畸形会对鼻腔和上颌骨的解剖结构产生负面影响。然而，这种畸形对泪腺系统的影响尚不明确。本研究旨在使用锥形束计算机断层扫描（CBCT）评估单侧CLP患者鼻泪管的形态学变化。
使用CBCT图像对28例CLP患者和28例对照患者的患侧和非患侧鼻泪管最窄横向直径和长度进行回顾性双侧测量，并对测量结果进行统计学比较。
单侧CLP患者患侧鼻泪管的平均最窄横向直径在统计学上显著窄于非患侧（P = 0.01）。在鼻泪管直径方面，对照组与单侧CLP患者组的患侧和非患侧之间无统计学显著差异。在所有组中，鼻泪管平均长度的差异无统计学意义。
单侧CLP患侧鼻泪管直径窄于非患侧。根据这一结果，CLP畸形可能会影响鼻泪管直径。然而，CLP可能不会影响鼻泪管长度。
