The relationship between posture and temporomandibular disease (TMD) is unclear. The aim of our study was to determine the influence of manual therapy (MT) on posture in TMD patients compared with healthy subjects. After consideration of inclusion and exclusion criteria, 30 subjects were included. These were divided into two groups: group A comprised 15 healthy subjects and group B 15 patients with present proven TMD disease. Rasterstereographic images were taken at different times. Group A subjects were scanned twice within half a year and group B before initiation as well as after the first MT and after completion of the prescribed MT. The different posture variables were calculated using DIERS Formetric software. To illustrate the differences between the two groups, 10 different postural variables were examined. Significant differences between the two groups were observed in pelvic tilt, surface rotation, and kyphotic apex. Pelvic tilt: mean = 7.581, p-value = 0.029; surface rotation: mean = 3.098, p = 0.049; and mean kyphotic apex = 11.538 and 11.946, respectively, with p-values of 0.037 and 0.029, respectively. MT leads to a change in posture in TMD patients. This could influence the course of TMD treatment.
姿势与颞下颌关节疾病(TMD)之间的关系尚不明确。我们的研究旨在确定与健康受试者相比,手法治疗(MT)对 TMD 患者姿势的影响。在考虑了纳入和排除标准后,我们纳入了 30 名受试者。这些受试者被分为两组:A 组包括 15 名健康受试者,B 组包括 15 名经证实患有 TMD 疾病的患者。在不同时间拍摄光栅立体图像。A 组受试者在半年内接受两次扫描,B 组受试者在开始 MT 之前、第一次 MT 之后以及完成规定的 MT 之后接受扫描。使用 DIERS Formetric 软件计算了不同的姿势变量。为了说明两组之间的差异,对 10 个不同的姿势变量进行了检查。两组在骨盆倾斜、表面旋转和畸形顶点方面存在显著差异。骨盆倾斜:平均值 = 7.581,P 值 = 0.029;表面旋转:平均值 = 3.098,P = 0.049;平均畸形顶分别为 11.538 和 11.946,P 值分别为 0.037 和 0.029。MT 导致 TMD 患者姿势的改变。这可能会影响 TMD 的治疗过程。

Pulsed radiofrequency (PRF) treatment targeting the greater occipital nerve (GON) has shown efficacy in treating various conditions. This double-blind, randomized controlled study aimed to evaluate the effects of combining PRF therapy with GON block (GONB) therapy in patients with chronic migraine. The study consisted of two groups: GONB and GONB + PRF, each comprising 16 patients with chronic migraine. Using 0.5-Hz sensorial stimulation, a 5-cm-long radiofrequency needle was inserted under ultrasound guidance in both groups. Subsequently, all patients received a GONB by administering 2 mL of 0.25% bupivacaine. In the GONB + PRF group, patients underwent 4 min of PRF at 42℃, whereas the GONB group did not receive any PRF treatment. Follow-up examinations were performed at 1, 2, 3 and 6 months after the procedure to evaluate the frequency and severity of migraine attacks, number of headache days, and analgesic consumption. In the GONB + PRF group, the visual analog scale (VAS) score, number of migraine attacks, number of headache days, and analgesic consumption were significantly lower compared to the GONB group (P < 0.05). Significant decreases (60%) in mean VAS scores, number of migraine attacks, number of headache days, and consumption of analgesic medications were observed in the GONB + PRF group at the 1-, 2-, 3-, and 6-month follow-ups compared with the pre-treatment period (P < 0.05). The combination of GONB and PRF presents a promising new treatment option for patients with chronic migraine. This approach has demonstrated efficacy in minimizing analgesic use, decreasing the frequency of migraine attacks, reducing the number of headache days and decreasing the severity of migraine attacks.

Background: Migraine affects one in ten individuals worldwide and is the second leading cause of disability. Studies have shown an association between migraine and the musculoskeletal system, and myofascial trigger points (MTrPs) play an essential role. Additionally, those with myofascial pain have been proven to experience higher levels of depression and anxiety. Understanding the association between MTrPs and migraine is crucial for developing targeted treatment strategies. Additionally, recognizing the link between MTrPs and migraine-related depression and anxiety underscores the importance of a holistic approach to migraine management. By addressing both musculoskeletal and neurological factors, healthcare providers can provide more effective and personalized care for migraine patients. This study aims to determine the association between MTrPs with migraine-related disability, anxiety, depression, and migraine characteristics.

Methods: This cross-sectional study included 68 migraine patients from an outpatient neurology clinic. The number of MTrPs was determined through examination by an experienced neurologist during a migraine-free period using the recommended international criteria. We evaluated anxiety and depression with the Hospital Anxiety and Depression Scale (HADS) and disability with the Migraine Disability Assessment Scale (MIDAS).

Results: We enrolled 68 patients (22 males) with a mean age of 36.23 ± 9.63 years. The mean number of MTrPs was 2.75 ± 2.934. MTrPs were positively correlated with severity (CC: 0.576, P-value < 0.001). There was no association between MTrPs and HADS-D or MIDAS, but migraine patients with abnormal HADS-A scores had more MTrPs than patients with normal HADS-A scores (0.6 ± 0.84 vs 3.56 ± 3.11, P-value:0.013).

Conclusions: The number of MTrPs is associated with higher anxiety levels and headache intensity. Further research could investigate the impact of MTrP-based therapies on anxiety among individuals suffering from migraines.

背景:偏头痛影响着全球十分之一的人,是导致残疾的第二大原因。研究表明,偏头痛与肌肉骨骼系统有关,而肌筋膜触发点(MTrPs)起着至关重要的作用。此外,患有肌筋膜疼痛的人被证明会有更高程度的抑郁和焦虑。了解 MTrPs 与偏头痛之间的联系对于制定有针对性的治疗策略至关重要。此外,认识到 MTrPs 与偏头痛相关的抑郁和焦虑之间的联系,也凸显了偏头痛综合治疗方法的重要性。通过解决肌肉骨骼和神经因素,医疗服务提供者可以为偏头痛患者提供更有效、更个性化的治疗。本研究旨在确定MTrPs与偏头痛相关残疾、焦虑、抑郁和偏头痛特征之间的关联:这项横断面研究包括神经内科门诊的 68 名偏头痛患者。MTrPs的数量是由一名经验丰富的神经科医生在无偏头痛期间根据推荐的国际标准进行检查后确定的。我们使用医院焦虑抑郁量表(HADS)评估了焦虑和抑郁情况,并使用偏头痛残疾评估量表(MIDAS)评估了残疾情况:我们共招募了 68 名患者(22 名男性),平均年龄为 36.23 ± 9.63 岁。MTrPs 的平均数量为 2.75 ± 2.934。MTrPs与病情严重程度呈正相关(CC:0.576,P值 结论:MTrPs数量与病情严重程度呈正相关:MTrPs的数量与较高的焦虑水平和头痛强度相关。进一步的研究可以探讨基于 MTrP 的疗法对偏头痛患者焦虑的影响。

Purpose: Nasoseptal perforations (NSP) are a clinically heterogeneous group of disorders with a wide range of available treatments. Patient-reported outcome measures (PROMs) can provide valuable insights for assessing clinical and surgical outcomes. This study aims to develop and validate a novel-specific questionnaire for patients with NSP.

Methods: A multi-centre prospective observational study was conducted at two tertiary referral hospitals. "Septal Perforation Quality of Life" (SEPEQOL) was developed by a committee of experts. The psychometric properties, including reproducibility, reliability, validity, and responsiveness, were assessed.

Results: The study included 96 symptomatic NSP patients and 30 healthy controls. SEPEQOL internal consistency was satisfactory [Cronbach´s α = 0.7843; 95% confidence interval (CI), 0.702-0.856]. Test-retest reliability was excellent, demonstrated by the absolute intraclass correlation (ICC = 0.974; 95% CI, 0.935-0.989, P-value < 0.001) and Bland-Altman plot (line bias = 1.6 ± 4.57; 95% CI -0.54-3.74, P-value < 0.001). The mean total SEPEQOL score was higher before surgery (25.16 ± 1.65) compared to 6-months after the procedure (13.72 ± 11.39), with a mean difference of 12.19 [standard deviation (SD) 10.76], P-value < 0.001.

Conclusions: SEPEQOL is reliable, consistent, valid, and sensitive to change over time. SEPEQOL assesses the impact of health-related quality of life on NSP and its management in clinical practice. Moreover, it is easy to apply in clinical settings with minimal burden.

目的:鼻中隔穿孔(NSP)是一种临床异质性疾病,有多种治疗方法可供选择。患者报告结果测量法(PROMs)可为评估临床和手术结果提供有价值的见解。本研究旨在开发并验证针对 NSP 患者的新型特异性问卷:在两家三级转诊医院开展了一项多中心前瞻性观察研究。由专家委员会编制了 "鼻中隔穿孔患者生活质量"(SEPEQOL)问卷。研究评估了该问卷的心理测量特性,包括再现性、可靠性、有效性和反应性:研究包括 96 名有症状的非典型肺炎患者和 30 名健康对照者。SEPEQOL 的内部一致性令人满意[Cronbach´s α = 0.7843;95% 置信区间 (CI),0.702-0.856]。通过绝对类内相关性(ICC = 0.974;95% CI,0.935-0.989,P 值)可以看出,测试-重测可靠性极佳:SEPEQOL 可靠、一致、有效,对随时间发生的变化非常敏感。SEPEQOL 可评估健康相关生活质量对非典型肺炎及其临床治疗的影响。此外,它易于在临床环境中应用,负担极小。

Background: To support dentists with limited experience, this study trained and compared six convolutional neural networks to detect crossbites and classify non-crossbite, frontal, and lateral crossbites using 2D intraoral photographs.

Methods: Based on 676 photographs from 311 orthodontic patients, six convolutional neural network models were trained and compared to classify (1) non-crossbite vs. crossbite and (2) non-crossbite vs. lateral crossbite vs. frontal crossbite. The trained models comprised DenseNet, EfficientNet, MobileNet, ResNet18, ResNet50, and Xception.

Findings: Among the models, Xception showed the highest accuracy (98.57%) in the test dataset for classifying non-crossbite vs. crossbite images. When additionally distinguishing between lateral and frontal crossbites, average accuracy decreased with the DenseNet architecture achieving the highest accuracy among the models with 91.43% in the test dataset.

Conclusions: Convolutional neural networks show high potential in processing clinical photographs and detecting crossbites. This study provides initial insights into how deep learning models can be used for orthodontic diagnosis of malocclusions based on intraoral 2D photographs.

背景:为了给经验有限的牙医提供支持,本研究使用二维口内照片训练并比较了六个卷积神经网络,以检测交叉咬合并对非交叉咬合、正面和侧面交叉咬合进行分类:方法: 根据 311 名正畸患者的 676 张照片,对六个卷积神经网络模型进行了训练和比较,以便对(1)非交叉咬合与交叉咬合;(2)非交叉咬合与侧面交叉咬合与正面交叉咬合进行分类。训练的模型包括 DenseNet、EfficientNet、MobileNet、ResNet18、ResNet50 和 Xception:在这些模型中,Xception 在测试数据集中对非交叉咬合与交叉咬合图像进行分类的准确率最高(98.57%)。在额外区分侧面和正面交叉咬合时,平均准确率有所下降,DenseNet 架构在测试数据集中的准确率最高,达到 91.43%:卷积神经网络在处理临床照片和检测交叉咬合方面显示出巨大潜力。这项研究为深度学习模型如何用于基于口内二维照片的畸齿矫正诊断提供了初步见解。

Background: Cranial, facial, nasal, and maxillary widths have been shown to be significantly affected by the individual's sex. The present study aims to use measurements of dental arch and maxillary skeletal base to determine sex, employing supervised machine learning.

Materials and methods: Maxillary and mandibular tomographic examinations from 100 patients were analyzed to investigate the inter-premolar width, inter-molar width, maxillary width, inter-pterygoid width, nasal cavity width, nostril width, and maxillary length, obtained through Cone Beam Computed Tomography scans. The following machine learning algorithms were used to build the predictive models: Logistic Regression, Gradient Boosting Classifier, K-Nearest Neighbors (KNN), Support Vector Machine (SVM), Multi-Layer Perceptron Classifier (MLP), Decision Tree, and Random Forest Classifier. A 10-fold cross-validation approach was adopted to validate each model. Metrics such as area under the curve (AUC), accuracy, recall, precision, and F1 Score were calculated for each model, and Receiver Operating Characteristic (ROC) curves were constructed.

Results: Univariate analysis showed statistical significance (p < 0.10) for all skeletal and dental variables. Nostril width showed greater importance in two models, while Inter-molar width stood out among dental measurements. The models achieved accuracy values ranging from 0.75 to 0.85 on the test data. Logistic Regression, Random Forest, Decision Tree, and SVM models had the highest AUC values, with SVM showing the smallest disparity between cross-validation and test data for accuracy metrics.

Conclusion: Transverse dental arch and maxillary skeletal base measurements exhibited strong predictive capability, achieving high accuracy with machine learning methods. Among the evaluated models, the SVM algorithm exhibited the best performance. This indicates potential usefulness in forensic sex determination.

Background: This study aimed to investigate the range of angles and depths necessary for effective entry into the TMJ using CBCT images, focusing on classical Holmlund Hellsing points and a two-needle approach.

Methods: A retrospective cohort of CBCT images from January 2020 to November 2023 was analysed using 3D analysis to determine the variance in the required angles and depths.

Results: The average age of the 68 participants included in the study was 29.5 ± 11.1, 58.8% of the participants were female and 41.2% were male. The anterior needle measurements showed a relatively low standard deviation(SD) in depth(SD:3.6) with a low variance coefficient(12.5%), whereas the axial and coronal angles exhibited greater variability(SD:9.1 and 7.6, respectively). For the posterior needles, moderate SDs in depth(SD:3.5) and greater variabilities in axial and coronal angles(SD:9.6 and 5.3, respectively) were observed. A weak negative correlation was observed between the axial angle of the posterior needle and age(p: 0.028, Pearson r: -0.29) Anterior needle depth (p:0.037) and posterior needle axial angle(p:0.014) were greater in males than females. The anterior needle depth in patients with temporamandibular disease was greater than in those without(p:0,03).

Conclusion: There were significant differences in the angle measurements for both anterior and posterior needles, but lower variance in depth. The depths and angles of the needles did not correlate with age.

背景:本研究旨在利用 CBCT 图像研究有效进入颞下颌关节的角度和深度范围:本研究旨在利用CBCT图像调查有效进入颞下颌关节所需的角度和深度范围,重点是经典的Holmlund Hellsing点和双针方法:方法:使用三维分析法对 2020 年 1 月至 2023 年 11 月期间的 CBCT 图像进行回顾性队列分析,以确定所需角度和深度的差异:68名参与者的平均年龄为(29.5±11.1)岁,58.8%为女性,41.2%为男性。前针测量的深度标准差(SD:3.6)相对较低,方差系数(12.5%)也较低,而轴向和冠状角的变异性较大(SD:分别为 9.1 和 7.6)。对于后针,观察到深度的中等变异系数(SD:3.5)以及轴向和冠状角的较大变异系数(SD:9.6 和 5.3)。观察到后针的轴角与年龄呈弱负相关(P:0.028,Pearson r:-0.29),男性的前针深度(P:0.037)和后针轴角(P:0.014)均大于女性。颞下颌关节疾病患者的前针深度大于非颞下颌关节疾病患者(P:0.03):结论:前针和后针的角度测量结果存在明显差异,但深度测量结果的差异较小。针的深度和角度与年龄无关。

Background: Tumorous diseases of the jaw demand effective treatments, often involving continuity resection of the jaw. Reconstruction via microvascular bone flaps, like deep circumflex iliac artery flaps (DCIA), is standard. Computer aided planning (CAD) enhances accuracy in reconstruction using patient-specific CT images to create three-dimensional (3D) models. Data on the accuracy of CAD-planned DCIA flaps is scarce. Moreover, the data on accuracy should be combined with data on the exact positioning of the implants for well-fitting dental prosthetics. This study focuses on CAD-planned DCIA flaps accuracy and proper positioning for prosthetic rehabilitation.

Methods: Patients post-mandible resection with CAD-planned DCIA flap reconstruction were evaluated. Postoperative radiograph-derived 3D models were aligned with 3D models from the CAD plans for osteotomy position, angle, and flap volume comparison. To evaluate the DCIA flap's suitability for prosthetic dental rehabilitation, a plane was created in the support zone and crestal in the middle of the DCIA flap. The lower jaw was rotated to close the mouth and the distance between the two planes was measured.

Results: 20 patients (12 males, 8 females) were included. Mean defect size was 73.28 ± 4.87 mm; 11 L defects, 9 LC defects. Planned vs. actual DCIA transplant volume difference was 3.814 ± 3.856 cm³ (p = 0.2223). The deviation from the planned angle was significantly larger at the dorsal osteotomy than at the ventral (p = 0.035). Linear differences between the planned DCIA transplant and the actual DCIA transplant were 1.294 ± 1.197 mm for the ventral osteotomy and 2.680 ± 3.449 mm for the dorsal (p = 0.1078). The difference between the dental axis and the middle of the DCIA transplant ranged from 0.2 mm to 14.8 mm. The mean lateral difference was 2.695 ± 3.667 mm in the region of the first premolar.

Conclusion: The CAD-planned DCIA flap is a solution for reconstructing the mandible. CAD planning results in an accurate reconstruction enabling dental implant placement and dental prosthetics.

背景:颌骨肿瘤疾病需要有效的治疗方法,通常需要连续切除颌骨。通过微血管骨瓣(如髂深环动脉瓣)进行重建是标准做法。计算机辅助规划(CAD)利用患者特定的 CT 图像创建三维(3D)模型,提高了重建的准确性。有关 CAD 规划的髂胫动脉皮瓣准确性的数据很少。此外,有关准确性的数据应与有关种植体准确定位的数据相结合,以获得良好的义齿修复效果。本研究的重点是 CAD 规划的 DCIA 皮瓣的准确性和修复体的正确定位:方法:对下颌切除术后使用 CAD 规划的 DCIA 皮瓣重建的患者进行评估。将术后X光片生成的三维模型与CAD计划的三维模型进行比对,以比较截骨位置、角度和皮瓣体积。为了评估 DCIA 皮瓣是否适合修复牙齿,在 DCIA 皮瓣中间的支撑区和嵴上创建了一个平面。将下颌旋转至闭合口腔,测量两个平面之间的距离。平均缺损大小为 73.28 ± 4.87 毫米;11 个 L 形缺损,9 个 LC 形缺损。计划与实际 DCIA 移植量的差异为 3.814 ± 3.856 立方厘米(p = 0.2223)。背侧截骨处与计划角度的偏差明显大于腹侧截骨处(p = 0.035)。计划的 DCIA 移植与实际 DCIA 移植之间的线性差异为:腹侧截骨为 1.294 ± 1.197 mm,背侧为 2.680 ± 3.449 mm(p = 0.1078)。牙轴与 DCIA 移植体中间的差值从 0.2 毫米到 14.8 毫米不等。第一前磨牙区域的平均侧差为 2.695 ± 3.667 mm:CAD规划的DCIA皮瓣是下颌骨重建的一种解决方案。CAD规划可实现精确的重建,使种植体植入和牙齿修复成为可能。

Aim: This study aimed to assess the effectiveness of advanced platelet-rich fibrin (A-PRF) combined with the pinhole surgical technique (PST) for enhancing root coverage (RC) in individuals with Miller class I or II gingival recessions (GR). Additionally, it compared the clinical effect of A-PRF and resorbable collagen membrane (RCM).

Materials and methods: A total of 18 patients, encompassing 36 treatment sides of 18 Miller class I or II, were randomly assigned to the PST + A-PRF side (18 sides) and the PST + RCM side (18 sides). Clinical assessments of various parameters, including plaque index (PI), clinical attachment level (CAL), keratinized tissue width (KTW), recession depth (RD), recession width (RW), and gingival thickness (GT) were conducted at baseline and three months after the surgical procedure. A numeric rating scale (NRS) was also evaluated during the 1st, 2nd, 3rd and 4th days. This study was formally recorded under the TCTR identification number TCTR20230613005 in the Thai Clinical Trials Register-Medical Research Foundation of Thailand (MRF) on 13/06/2023. Furthermore, it was ethically approved by Sana'a University's Ethical Committee for Medical Research.

Results: When comparing the values of 3 months follow-up with the baseline values, intra-side comparison of the PST + A-PRF group showed significant improvements in PI (P = 0.02), CAL (P = 0.01), and RD (P = 0.04), and GT values (P < 0.01). The improvements in the PST + A-PRF group were through the reduction of baseline values of PI, CAL, and RD; the mean reductions in PI, CAL, and RD were 0.44 ± 0.71, 0.33 ± 0.45, and 0.22 ± 0.43 respectively, and a significant increase in GT value (0.44 ± 0.24). While there was an insignificant increase in KTW value with no change in RW values (4.50 ± 0.71, P = 1). In contrast, intra- side comparison of PST + RCM side showed only a significant reduction in PI value (0.44 ± 0.71, P = 0.02) and a significant increase in GT value (0.42 ± 0.26, P = < 0.01). Meanwhile, there were insignificant improvements in CAL (2.89 ± 0.95), KTW (3.97 ± 0.74), and RD (1.94 ± 0.87) values. Regarding inter-side comparison, there were no statistically significant among all variables (p > 0.05). The pain scores of the numeric rating scale were significantly lower on the PST + A-PRF sides compared with the PST + RCM sides, especially on the 1st, 2nd, and 3rd days (P < 0.001).

Conclusion: Both A-PRF and RCM showed not wholly satisfactory outcomes in gingival recession treatment. Interestingly, the combination of PST with A-PRF has proven more effective than combining PST with RCM. Additionally, the localized application of A-PRF has been shown to reduce post-operative pain following the pinhole surgical technique.

目的:本研究旨在评估高级富血小板纤维蛋白(A-PRF)与针孔手术技术(PST)相结合对米勒Ⅰ级或Ⅱ级牙龈退缩(GR)患者提高牙根覆盖率(RC)的有效性。此外,该研究还比较了 A-PRF 和可吸收胶原膜 (RCM) 的临床效果:共 18 名患者,包括 18 个米勒 I 级或 II 级的 36 个治疗侧,被随机分配到 PST + A-PRF 侧(18 侧)和 PST + RCM 侧(18 侧)。在基线和手术后三个月对各种参数进行临床评估,包括牙菌斑指数(PI)、临床附着水平(CAL)、角化组织宽度(KTW)、牙龈退缩深度(RD)、牙龈退缩宽度(RW)和牙龈厚度(GT)。此外,还在第一、第二、第三和第四天进行了数字评分表(NRS)评估。本研究于 2023 年 6 月 13 日在泰国临床试验登记处--泰国医学研究基金会(MRF)正式登记,编号为 TCTR20230613005。此外,该研究还获得了萨那大学医学研究伦理委员会的伦理批准:将 3 个月的随访值与基线值进行比较,PST + A-PRF 组的组内比较显示,PI(P = 0.02)、CAL(P = 0.01)、RD(P = 0.04)和 GT 值(P 0.05)均有显著改善。与 PST + RCM 侧相比,PST + A-PRF 侧的数字评级量表疼痛评分明显降低,尤其是在第 1、2 和 3 天(P 结论:PST + A-PRF 侧的数字评级量表疼痛评分明显低于 PST + RCM 侧):A-PRF 和 RCM 在治疗牙龈退缩方面的效果并不完全令人满意。有趣的是,PST 与 A-PRF 的结合比 PST 与 RCM 的结合更有效。此外,A-PRF 的局部应用还能减轻针孔手术技术的术后疼痛。

Since many different conclusions of craniofacial anomalies and their relation to the posterior airway space coexist, this comparative clinical study investigated the palatal morphology concerning volumetric size, posterior airway space dimension and the adenoids of patients with and without a cleft before orthodontic treatment. Three-dimensional intraoral scans and cephalometric radiographs of n = 38 patients were used for data acquisition. The patients were divided into three groups: unilateral cleft lip and palate (n = 15, 4 female, 11 male; mean age 8.57 ± 1.79 years), bilateral cleft lip and palate (n = 8, 0 female, 8 male; mean age 8.46 ± 1.37 years) and non-cleft control (n = 15, 7 female, 8 male; mean age 9.03 ± 1.02 years). The evaluation included established procedures for measurements of the palatal morphology and posterior airway space. Statistics included Shapiro-Wilk-Test and simple ANOVA (Bonferroni) for the three-dimensional intraoral scans and cephalometric radiographs. The level of significance was set at p < 0.05. The palatal volume and cephalometric analysis showed differences between the three groups. The palatal volume, the superior posterior face height and the depth of the bony nasopharynx of patients with cleft lip and palate were significantly smaller than for non-cleft control patients. The superior posterior face height of bilateral cleft lip and palate patients was significantly smaller than in unilateral cleft lip and palate patients (BCLP: 35.50 ± 2.08 mm; UCLP: 36.04 ± 2.95 mm; p < 0.001). The percentage of the adenoids in relation to the entire nasopharynx and the angle NL/SN were significantly bigger in patients with cleft lip and palate than in the non-cleft control. In particular, the palatal volume was 32.43% smaller in patients with unilateral cleft lip and palate and 48.69% smaller in patients with bilateral cleft lip and palate compared to the non-cleft control. Skeletal anomalies relate to the dimension of the posterior airway space. There were differences among the subjects with cleft lip and palate and these without a cleft. This study showed that the morphology of the palate and especially transverse deficiency of the maxilla resulting in smaller palatal volume relates to the posterior airway space. Even the adenoids seem to be affected, especially for cleft lip and palate patients.
由于颅面畸形及其与后气道间隙的关系存在多种不同的结论,这项临床对比研究调查了腭裂患者和非腭裂患者在正畸治疗前的腭部形态,包括体积大小、后气道间隙尺寸和腺样体。研究采用了 n = 38 名患者的口内三维扫描和头颅X光片来获取数据。患者分为三组:单侧唇腭裂(n = 15,4 女,11 男;平均年龄为 8.57 ± 1.79 岁)、双侧唇腭裂(n = 8,0 女,8 男;平均年龄为 8.46 ± 1.37 岁)和非唇腭裂对照组(n = 15,7 女,8 男;平均年龄为 9.03 ± 1.02 岁)。评估包括测量腭部形态和后气道空间的既定程序。统计数据包括口内三维扫描和头颅X光片的 Shapiro-Wilk 检验和简单方差分析(Bonferroni)。显著性水平设定为 p < 0.05。腭容积和头影分析表明三组之间存在差异。唇腭裂患者的腭容积、面后上方高度和鼻咽骨性深度明显小于非唇腭裂对照组患者。双侧唇腭裂患者的面后上方高度明显小于单侧唇腭裂患者(BCLP:35.50 ± 2.08 mm;UCLP:36.04 ± 2.95 mm;P < 0.001)。唇腭裂患者的腺样体占整个鼻咽部的百分比和 NL/SN 角明显大于非唇腭裂对照组。特别是,与非唇腭裂对照组相比,单侧唇腭裂患者的腭部体积小 32.43%,双侧唇腭裂患者的腭部体积小 48.69%。骨骼异常与后气道空间的尺寸有关。唇腭裂患者与非唇腭裂患者之间存在差异。这项研究表明,腭部的形态,尤其是上颌骨的横向缺损导致腭部体积较小,与后气道空间有关。甚至腺样体似乎也受到影响,尤其是唇腭裂患者。
