The contribution of frontal tomography to the diagnosis of temporomandibular joint (TMJ) osteoarthritis has been investigated. Ninety-one patients with clinically defined TMJ disorders were examined by simultaneous lateral and frontal TMJ tomograms taken in the intercuspal position. Abnormal findings were observed on frontal tomograms in 31 joints and suspicious findings in 22 joints. On the other hand, there were 41 joints with abnormal findings and 22 joints with suspicious findings on the lateral tomograms. Suspicious or abnormal findings were found on frontal tomograms alone in 14 joints (7.7%) of 14 patients (15.4%). It is concluded that simultaneous lateral and frontal tomography produces a more accurate radiographic diagnosis of TMJ osteoarthritis.
研究了额部断层扫描对颞下颌关节（TMJ）骨关节炎诊断的贡献。91例临床诊断为颞下颌关节紊乱的患者在牙尖交错位时同时进行了颞下颌关节侧位和额部断层扫描检查。在额部断层扫描中，31个关节观察到异常表现，22个关节观察到可疑表现。另一方面，在侧位断层扫描中，41个关节有异常表现，22个关节有可疑表现。仅在额部断层扫描中发现可疑或异常表现的有14例患者的14个关节（7.7%）（15.4%）。得出的结论是，同时进行侧位和额部断层扫描能对颞下颌关节骨关节炎做出更准确的影像学诊断。
