The disuse of the jaws owing to the restricted movement of the mandible in advanced cases of oral submucous fibrosis (OSMF) may have an effect on the morphologic features of the jaw bones. The purpose of the present study was to determine the jaw bone measurements in patients with OSMF and to compare the measurements in normal subjects and Caucasian norms.
The lateral cephalograms of 59 subjects (43 males and 16 females) with OSMF and 44 normal subjects (23 males and 21 females) in the age group of 18-45 years were collected. The jaw measurements were performed using Burstone analysis, and the relevant linear measurements of jaw sizes included were N-A, N-B, N-ANS, ANS-PNS, ANS-Gn, Ar-Go, and Pg-Go. The sex-wise comparison was performed using unpaired t-test, and measurements were compared with other studies using Z test.
In the present study, sex-wise comparison was found to be significant with greater jaw measurements in males than in females in patients with OSMF. Overall, the measurements were less or equal in patients with OSMF than in normal subjects except for N-ANS and Pg-Go. When study measurements were compared with Burstone measurements, differences were significant with greater and less measurements.
Overall, the jaw measurements were less or equal in patients with OSMF than in normal subjects except for mandibular body length and middle third facial height that may need further evaluation.
在晚期口腔黏膜下纤维化（OSMF）病例中，由于下颌骨活动受限导致颌骨废用，这可能会对颌骨的形态特征产生影响。本研究的目的是确定OSMF患者的颌骨测量值，并将这些测量值与正常受试者及高加索人标准进行比较。
收集了59名年龄在18 - 45岁之间的OSMF受试者（43名男性和16名女性）以及44名正常受试者（23名男性和21名女性）的头颅侧位片。使用Burstone分析法进行颌骨测量，所包括的颌骨大小的相关线性测量值有N - A、N - B、N - ANS、ANS - PNS、ANS - Gn、Ar - Go和Pg - Go。采用非配对t检验进行性别间比较，并使用Z检验将测量值与其他研究进行比较。
在本研究中，发现性别间比较具有显著性差异，OSMF患者中男性的颌骨测量值大于女性。总体而言，除了N - ANS和Pg - Go外，OSMF患者的测量值小于或等于正常受试者。当将本研究的测量值与Burstone测量值进行比较时，差异显著，有更大和更小的测量值。
总体而言，除了可能需要进一步评估的下颌体长和面部中三分之一高度外，OSMF患者的颌骨测量值小于或等于正常受试者。
