Soft palate (velar) plays a significant role in various important functions in the head and neck region. Its diverse morphology is implicated in a variety of diseases. Knowledge about the varied morphological pattern of soft palate in oral submucous fibrosis (OSMF) patients can give us a clear understanding about disease progress in the oropharyngeal region for a proper diagnosis and also help the maxillofacial surgeon in successful structural and functional corrections associated with this disorder.
(1) To evaluate the morphological variations of soft palate in OSMF patients using digital lateral cephalogram. (2) To assess the morphological variations of soft palate with respect to the different clinical stages of OSMF patients.
A total number of 300 patients were included in the study (150 participants each in study and control group), evaluated clinically, and subjected for digital lateral cephalogram for evaluating velar morphological variants.
The data were statistically evaluated using SPSS 11.5 software with Student's t-test, Chi-square test, and ANOVA.
Among Group I, 34 participants had Stage I OSMF, 90 participants had Stage II OSMF, and 26 participants had Stage III OSMF. Type I velar was commonly seen in Stage I OSMF, Type VI velar in Stage II OSMF, and Type III velar in Stage III OSMF. There was statistically highly significant decrease in anterior-posterior (AP) length and increase in width of superior-inferior (SI) measurement, as compared to the Group II.
There was diminution in AP length and increase in SI measurement as the OSMF disease progressed.
软腭在头颈部的各种重要功能中起着重要作用。其多样的形态与多种疾病相关。了解口腔黏膜下纤维化（OSMF）患者软腭的不同形态模式，有助于我们清楚了解口咽区域的疾病进展，以便进行正确诊断，也有助于颌面外科医生成功进行与该疾病相关的结构和功能矫正。
（1）使用数字化侧位头影测量片评估OSMF患者软腭的形态变化。（2）评估软腭形态变化与OSMF患者不同临床分期的关系。
本研究共纳入300例患者（研究组和对照组各150例），进行临床评估，并接受数字化侧位头影测量以评估软腭形态变异。
使用SPSS 11.5软件，采用学生t检验、卡方检验和方差分析对数据进行统计学评估。
在第一组中，34例参与者为I期OSMF，90例参与者为II期OSMF，26例参与者为III期OSMF。I型软腭常见于I期OSMF，VI型软腭常见于II期OSMF，III型软腭常见于III期OSMF。与第二组相比，前后（AP）长度在统计学上有极显著降低，上下（SI）测量宽度增加。
随着OSMF疾病进展，AP长度减小，SI测量值增加。
