Patients presenting with neck mass are challenging for many otolaryngologists. If a mass on the lower lateral neck exists with swallowing and disappears after swallowing, it has been diagnosed as an omohyoid syndrome in most literature. The mechanism of sternohyoid syndrome has not been proven or investigated before. We investigated sternohyoid syndrome, commonly misdiagnosed as an omohyoid syndrome.
Two patients were investigated. Outpatient photography, computed tomography and operating findings were reviewed. We found that the sternohyoid muscle was inserted at an abnormal site, the midportion of the clavicle. There was no abnormality of other muscles. We also reviewed all literature that previously diagnosed this condition as an omohyoid syndrome.
There was no literature about sternohyoid syndrome. We found that the abnormal muscle is a sternohyoid muscle and not omohyoid muscle. The color of the left sternohyoid muscle was dark red, and the fascia covering the muscle was denuded. The muscle had lost elasticity and moved abnormally.
Our patients did not have omohyoid syndrome. The symptoms of omohyoid syndrome are the same as sternohyoid syndrome but the problematic muscle is different. This is the first known report diagnosing sternohyoid syndrome, and should be a consideration in the diagnosis of a lateral neck mass.
对许多耳鼻喉科医生来说，颈部肿块患者的诊断颇具挑战性。如果在下侧颈部存在一个肿块，吞咽时出现，吞咽后消失，在大多数文献中已被诊断为肩胛舌骨肌综合征。胸骨舌骨肌综合征的机制此前尚未得到证实或研究。我们对常被误诊为肩胛舌骨肌综合征的胸骨舌骨肌综合征进行了研究。
对两名患者进行了研究。回顾了门诊照片、计算机断层扫描和手术结果。我们发现胸骨舌骨肌附着于异常部位，即锁骨中部。其他肌肉无异常。我们还回顾了所有此前将这种情况诊断为肩胛舌骨肌综合征的文献。
尚无关于胸骨舌骨肌综合征的文献。我们发现异常肌肉是胸骨舌骨肌而非肩胛舌骨肌。左侧胸骨舌骨肌颜色呈暗红色，覆盖该肌肉的筋膜剥脱。该肌肉失去弹性且运动异常。
我们的患者没有肩胛舌骨肌综合征。肩胛舌骨肌综合征的症状与胸骨舌骨肌综合征相同，但问题肌肉不同。这是首次诊断胸骨舌骨肌综合征的已知报告，在诊断侧颈部肿块时应予以考虑。
