口腔粘膜下纤维性变（Oral submucous fibrosis，OSMF）是一种慢性进行性、瘢痕性的口腔疾病，主要累及颊粘膜、舌、唇、前牙柱、软腭和口咽。软腭形态学的变化甚至在OSMF之前就开始了，临床上表现出来。这些变化会导致睡眠呼吸暂停、言语、吞咽和呼吸困难。各种X线片是评估软腭及其形态或任何形态变化的良好诊断辅助工具。通过影像学评价，评价并比较OSMF不同阶段的软腭形态和尺寸，并与对照组进行比较。对60例患者进行头颅侧位片和锥形束CT（CBCT）检查，比较软腭形态、长度、宽度和角度。两组中最常见的软腭类型均为1型（叶状），两种影像学技术也是如此。随着OSMF组等级的增加，长度显著减少，宽度增加。根据p值，CBCT给出了更精确的结果。随着OSMF的进展，软腭变得坚固和笨重，软腭尺寸发生显著变化，CBCT可以更好地评价。由于软腭受累是最早发现的变化，因此X线片应作为OSMF患者的诊断辅助手段之一。
Oral submucous fibrosis (OSMF) is a chronic progressive, scarring disorder of oral cavity, which includes buccal mucosa, tongue, lips, anterior faucial pillars, soft palate, and oropharynx. Changes in soft palate morphology will start even before the OSMF, present itself clinically. These changes can lead to sleep apnea, difficulty in speech, swallowing & respiration. Various radiographs are good diagnostic aid to assess the soft palate and its morphology or any changes in morphology. To evaluate and compare soft palate morphology and dimensions in various stages of OSMF with control by radiographic evaluation.: 60 patients were evaluated and compared for soft palate morphology, its length, width and angle by using lateral cephalogram and Cone beam computed tomography (CBCT). Most common type of soft palate was found to be type 1 (leaf shaped) in both groups as well as by both radiographic techniques. Significant decrease in length and increase in width with increasing grades of OSMF group. As per p value CBCT gave more precise result. As the OSMF progresses soft palate becomes stout and bulky and significant changes occur in soft palate dimensions and are better evaluated by CBCT. As involvement of the soft palate is the earliest change to be noticed, radiographs should be used as one of the diagnostic aids in OSMF patients.
