This study aims to evaluate whether the uptake difference by the condyles evaluated using single photon emission computed tomography (SPECT) examination is useful for predicting the activity of the feature and the advance of this pathology.
An observational and prospective study has been carried out on nine patients affected by unilateral condylar hyperplasia (UCH) with complete bone maturation, with a follow-up over 18 months. At the beginning of the study, a test-battery was conducted including dental casts, articular examination, teleradiography and cephalometry, computed tomography and SPECT, creating two groups of patients from a difference in uptake between both condyles greater than 10% over the follow-up period. Evolution of data obtained with the rest of the diagnostic tests were compared to confirm UCH activity predicted by SPECT.
The comparison of both groups did not show hardly any significant differences, with little clinical significance. Deviation of the mandibular line, the size of the branches or condyles behaved similarly in both study groups.
From the data obtained in our study, we can conclude that the use of the difference in uptake between both condyles by applying the SPECT technique is not a valid approach for predicting clinical activity in cases of UCH.
本研究旨在评估使用单光子发射计算机断层扫描 (SPECT) 检查评估的髁突摄取差异是否可用于预测该特征的活性和该病理学的进展。
对 9 名单侧髁突肥大症（UCH）患者进行了一项观察性和前瞻性研究，这些患者均已完全骨成熟，随访时间超过 18 个月。在研究开始时，进行了一系列测试，包括牙模、关节检查、远距射线照相和头影测量、计算机断层扫描和 SPECT，根据在随访期间两个髁突之间的摄取差异大于 10%，将患者分为两组。比较其余诊断测试获得的数据的演变，以确认 SPECT 预测的 UCH 活动。
两组之间的比较几乎没有显示出任何显著差异，临床意义不大。下颌线、分支或髁突的大小在两个研究组中的表现相似。
根据我们研究中获得的数据，我们可以得出结论，使用 SPECT 技术评估两个髁突之间的摄取差异并不能有效预测 UCH 病例的临床活动。
