To assess radiographically the presence of an ossified stylohyoid complex (OSHC) with signs and symptoms of Eagle syndrome or other oro-facial painful diseases in patients attending our institution and to confirm that the important issue for study is to know the length of the ossificated portion of the stylohyoid complex only.
We separated 1000 consecutive files, and after selection, 922 panoramic radiographs were evaluated. Assessed parameters were gender and age of the patients, size, and location of the analyzed OSHCs. In addition, the length parameters of the studied OSHCs were also determined in 100 extra radiographs.
Normal length of OSHCs was between 2.83 and 4.16 cm and OSHCs measuring more than 4.17 cm long comprising 23.2% of the sample. Any of the patients with OSHC presented signs or symptoms of the Eagle syndrome or any other orofacial painful disease.
This is the first study on OSHCs using the mandatory parameters of normal, short and elongated length in the studied population. Our results suggest that the presence of an OSHC is not an important feature for pain detection in the Eagle syndrome and is not an important risk factor for development of throat pain in this and other painful orofacial diseases. Our results are different from those previously published in other populations and suggest that the widely used lengths of 2 to 4 cm for measuring the OSHCs are not adequate parameter. It is desirable to define first the short, normal and abnormal parameters of OSHCs in each studied population.
通过影像学评估在我院就诊的患有鹰综合征体征和症状或其他口腔面部疼痛性疾病的患者中骨化茎突舌骨复合体（OSHC）的存在情况，并确认研究的重要问题仅在于了解茎突舌骨复合体骨化部分的长度。
我们筛选了1000份连续的病例档案，经过挑选后，对922张全景X线片进行了评估。评估的参数包括患者的性别和年龄、所分析的OSHC的大小和位置。此外，还在100张额外的X线片上确定了所研究的OSHC的长度参数。
OSHC的正常长度在2.83至4.16厘米之间，长度超过4.17厘米的OSHC占样本的23.2%。任何患有OSHC的患者均未出现鹰综合征或任何其他口腔面部疼痛性疾病的体征或症状。
这是第一项在研究人群中使用正常、短和长长度等强制性参数对OSHC进行的研究。我们的结果表明，OSHC的存在并非鹰综合征疼痛检测的重要特征，也不是该疾病及其他口腔面部疼痛性疾病发生咽痛的重要危险因素。我们的结果与先前在其他人群中发表的结果不同，表明广泛使用的2至4厘米的OSHC测量长度并非合适的参数。在每个研究人群中首先定义OSHC的短、正常和异常参数是很有必要的。
