The styloid process is a bony projection, located just anterior to the stylomastoid foramen, the normal length of which is approximately 20-25 mm. Elongation of the process may cause various clinical symptoms such as neck and cervicofacial pain, described as Eagle's syndrome. The present study aimed to determine the mean length of the styloid process on cadavers, panoramic radiographs, and dry skulls, and to investigate the incidence of the elongated styloid process, while assessing the elongation in relation to Eagle's syndrome. When the measurements from the panoramic radiographs were assessed, the mean length of the styloid processes in males and females on the right and left sides were found to be the following: 25.78 + or - 5.68 mm; 22.69 + or - 3.68 mm, 25.80 + or - 5.75 mm; and 22.75 + or - 3.65 mm, respectively. The males had greater styloid process lengths than the females, and the differences in length on both the right and left sides were statistically significant. Descriptive statistics and comparison results according to age groups were determined. There was no statistically significant difference between right or left styloid process lengths according to age groups. The mean length of the styloid process of the cadavers and dry bones was 22.54 + or - 4.24, and there was no significant difference between the right and left sides of the cadavers and dry bones. The incidence of the elongated styloid process was determined as 3.3%, and the elongations revealed a female dominance. The average length of the elongated styloid process was 36.06 + or - 6.12 mm, while the mean length of the styloid processes of the subjects reporting Eagle's syndrome was 40 + or - 4.72 mm. The results of this morphological study will assist clinicians in the diagnosis of Eagle's syndrome.
茎突是一个骨性突起，位于茎乳孔前方，其正常长度约为20 - 25毫米。茎突过长可能会引起各种临床症状，如颈部和颈面部疼痛，即所谓的鹰综合征。本研究旨在确定尸体、全景X线片和干燥颅骨上茎突的平均长度，调查茎突过长的发生率，并评估与鹰综合征相关的茎突延长情况。在评估全景X线片测量结果时，发现男性和女性左右两侧茎突的平均长度如下：右侧分别为25.78±5.68毫米；左侧为22.69±3.68毫米，右侧为25.80±5.75毫米；左侧为22.75±3.65毫米。男性的茎突长度大于女性，左右两侧长度差异具有统计学意义。确定了按年龄组的描述性统计和比较结果。按年龄组划分，左右茎突长度之间没有统计学上的显著差异。尸体和干燥骨骼的茎突平均长度为22.54±4.24，尸体和干燥骨骼左右两侧之间没有显著差异。茎突过长的发生率确定为3.3%，且延长情况女性占主导。茎突过长的平均长度为36.06±6.12毫米，而报告有鹰综合征的受试者茎突的平均长度为40±4.72毫米。这项形态学研究的结果将有助于临床医生诊断鹰综合征。
