下颌外伤的颈区疼痛可由茎突骨折引起。这常是压迫舌咽神经所致,因为该神经穿过茎突和第一颈椎之间的间隙内。外伤累及茎突之文献很少。Rowe和Killey认为此系罕见之下颌骨折的并发症。Bird曾描述有一摩托车祸患者两侧髁状突骨折和下颌联合处斜行骨折,患者吞咽困难较骨碎片移位严重,此种困难在下颌骨折复位后仍存在。进而作X线照片证明右茎突中部骨折。 Cervical pain in mandibular trauma can be caused by fractures of the styloid process. This is usually caused by oppression of the glossopharyngeal nerve, because the nerve penetrates the space between the styloid process and the first cervical vertebra. There is little literature on traumatic involvement of the styloid process. Rowe and Killey think this is a rare complication of mandibular fracture. Bird described a motorcycle accident on both sides of the condylar fracture and mandibular joint oblique fracture, the patient had severe dysphagia compared with bone fragments shift, such difficulties still exist after the reduction of mandibular fracture. Further X-ray photographs to prove the right styloid process of the central fracture.
