Abstract

Background: The incisive foramen width was a traditional imaging criterion for diagnosing nasopalatine duct (NPD) cysts. Recent CBCT studies demonstrated significant dimensional variations of the nasopalatine canal, which raised questions about the accuracy of this criterion. This study investigated whether nasopalatine canal diameters assessed on CBCT images can accurately differentiate NPD cysts from normal nasopalatine canals.

Methods: The study included 19 patients with NPD cysts (12 (63.2%) males, 7 (36.8%) females, mean age 44.7 ± 13.3), and a control group of 164 patients (72 (43.9%) males, 92 (56.1%) females, mean age 47.25 ± 17.74). CBCT images were retrospectively evaluated. The following nasopalatine canal diameters were measured on reference sagittal, coronal, and axial reformation images: nasal opening anteroposterior (AP) and mediolateral (ML) diameter, oral opening AP (APOO) and ML (MLOO) diameter, nasopalatine canal length, minimum ML (minML) diameter, anterior wall expansion (AWE), nasopalatine canal angle, and the mid-level AP diameter (midAP). All parameters were compared between groups. Discriminant functional analysis (DFA) was applied to detect CBCT parameters that best differentiate the NPD cyst from the normal canal.

Results: Patients with NPD cyst had significantly greater values of APOO (7.06 ± 2.09 vs. 5.61 ± 1.70), MLOO (6.89 ± 2.95 vs. 3.48 ± 1.24), minML (2.88 ± 1.53 vs. 2.25 ± 1.09), AWE (2.15 ± 0.65 vs. 0.41 ± 0.67), and midAP (4.58 ± 1.61 vs. 2.48 ± 0.96). DFA showed MLOO, AWE, and midAP as the most accurate in distinguishing NPD cyst from the normal canal. When combined in the discriminant function equation X = 0.390·MLOO + 1.010·AWE + 0.288·midAP (cut score 1.669), the differentiation can be performed with a sensitivity and specificity of 98.8% and 76.9%, respectively.

Conclusion: NPD cysts can be accurately distinguished from the normal nasopalatine canal by measuring MLOO, AWE, and midAP diameter on CBCT images.

准确区分鼻腭管囊肿和正常鼻腭管的 CBCT 形态学参数。

背景：切孔宽度是诊断鼻腭管（NPD）囊肿的传统成像标准。最近的 CBCT 研究表明，鼻腭管的尺寸变化很大，这就对这一标准的准确性提出了质疑。本研究探讨了 CBCT 图像上评估的鼻腭管直径能否准确区分 NPD 囊肿和正常鼻腭管：研究对象包括19例NPD囊肿患者（男性12例（63.2%），女性7例（36.8%），平均年龄（44.7 ± 13.3）岁）和164例对照组患者（男性72例（43.9%），女性92例（56.1%），平均年龄（47.25 ± 17.74）岁）。对 CBCT 图像进行了回顾性评估。在参考矢状面、冠状面和轴向重塑图像上测量了以下鼻腭管直径：鼻腔开口前胸（AP）和内外侧（ML）直径、口腔开口AP（APO）和ML（MLOO）直径、鼻腭管长度、最小ML（minML）直径、前壁扩张（AWE）、鼻腭管角度和中层AP直径（midAP）。所有参数均在组间进行比较。应用判别功能分析（DFA）检测最能区分鼻腭管囊肿和正常鼻腭管的 CBCT 参数：结果：NPD 囊肿患者的 APOO（7.06±2.09 vs. 5.61±1.70）、MLOO（6.89±2.95 vs. 3.48±1.24）、minML（2.88±1.53 vs. 2.25±1.09）、AWE（2.15±0.65 vs. 0.41±0.67）和 midAP（4.58±1.61 vs. 2.48±0.96）值明显更高。DFA 显示 MLOO、AWE 和 midAP 在区分 NPD 囊肿和正常管腔方面最为准确。如果将其合并到判别函数方程 X = 0.390-MLOO + 1.010-AWE + 0.288-midAP（切分分值 1.669）中，区分的灵敏度和特异度分别为 98.8%和 76.9%：结论：通过测量 CBCT 图像上的 MLOO、AWE 和 midAP 直径，可将鼻腭管囊肿与正常鼻腭管准确区分开来。

期刊介绍： Head & Face Medicine is a multidisciplinary open access journal that publishes basic and clinical research concerning all aspects of cranial, facial and oral conditions. The journal covers all aspects of cranial, facial and oral diseases and their management. It has been designed as a multidisciplinary journal for clinicians and researchers involved in the diagnostic and therapeutic aspects of diseases which affect the human head and face. The journal is wide-ranging, covering the development, aetiology, epidemiology and therapy of head and face diseases to the basic science that underlies these diseases. Management of head and face diseases includes all aspects of surgical and non-surgical treatments including psychopharmacological therapies.
