Abstract：
OBJECTIVE: The styloid process (SP) becomes clinically relevant when it shows enlargement (>30 mm) in the sense of an elongated SP (ESP) and/or increasing calcification leading to Eagle Syndrome (ES). Panoramic radiograph (PR) or computed tomography (CT) are part of the routine diagnostics in ES. Currently, CT is considered the gold standard. The aim of this study was to investigate the accuracy in the diagnostics/measurements of SP/ESP throughout a comparative study between PR and CT. Furthermore, in addition to measuring established parameters, this study aimed to determine the currently unexamined width in the base and tip of the SP.
METHODS: The present study examined the radiological findings of bilateral SP in 100 patients who received both PR and CT on the same day. Measurements of the length of the SP and width at the basis and tip were performed. Furthermore, calcification patterns, Langlais classification and the prevalence of ESP were analyzed.
RESULTS: There was a highly significant correlation between PR and CT measuring SP for every parameter. Males showed significantly longer SP than females among the age group between 18-75 years. The results of the length measurements of the SP (male: right SP=32.98 mm; left SP=35.21 mm; female: right SP=30.31 mm; left SP=30.92 mm) significantly exceeded the values of comparable studies.
CONCLUSIONS: Consequently, it can be concluded that PR provides accurate measurements when compared to CT for measuring and diagnosing SP/ESP/Eagle syndrome. This study was one of the first to examine the width of the SP in the base and tip, thus these measurements can serve as a baseline for further studies. Since the mean lengths of SP exceeded 30.0 mm in the present study, these findings raise the question of whether the cut-off of 30.0 mm is adequate for the diagnosis of ESP.

摘要：
目的：茎突（SP）在细长的SP（ESP）和/或钙化增加的意义上表现出增大（>30mm），从而导致鹰综合征（ES），从而具有临床相关性。全景图（PR）或计算机断层扫描（CT）是ES常规诊断的一部分。目前,CT被认为是金标准。这项研究的目的是在PR和CT之间的比较研究中调查SP/ESP的诊断/测量的准确性。此外，除了测量既定的参数，本研究旨在确定SP底部和尖端的当前未检查宽度。
方法：本研究检查了在同一天接受PR和CT的100例患者的双侧SP的放射学发现。在基底和尖端处进行SP的长度和宽度的测量。此外，钙化模式,分析Langlais分类和ESP的患病率。
结果：对于每个参数，PR和CT测量SP之间存在高度显著的相关性。在18-75岁的年龄组中，男性的SP明显长于女性。SP的长度测量结果（男性：右侧SP=32.98mm；左侧SP=35.21mm；女性：右侧SP=30.31mm；左侧SP=30.92mm）显着超过了可比研究的值。
结论：因此，可以得出结论，与CT相比，PR提供了准确的测量结果，用于测量和诊断SP/ESP/Eagle综合征。这项研究是第一个检查底部和尖端的SP宽度的研究之一，因此,这些测量值可以作为进一步研究的基线.由于本研究中SP的平均长度超过30.0毫米，这些发现提出了一个问题,即30.0mm的截距是否足以诊断ESP.
