Fracture of the mandibular genial tubercles is an uncommon pathology affecting edentulous patients with severe maxillary atrophy. Usually occurs spontaneously which complicates the diagnosis. Their importance lies in the functional alterations, which occur as a consequence of the disinsertion of the genihyoid and genioglossus muscles. The treatment of fracture of the genial tubercles is controversial, including no surgical intervention, excision of the avulsed bone fragments, and muscular repositioning. There have been only 11 cases reported in the literature of this fracture, most of them spontaneous. We present a difficult diagnosis situation of spontaneous fracture of the genial tubercles in an 86-year-old edentulous female with a painful sublingual and submental hematoma and anterior cervical echimosis. Computerized Tomography should be made to confirm the diagnosis. Surgical treatment was not necessary, and follow-up at 6 months revealed complete symptomatic recovery, and full return of function.
下颌颏结节骨折是一种罕见的病理情况，影响患有严重上颌骨萎缩的无牙患者。通常为自发性发生，这使得诊断变得复杂。其重要性在于功能改变，这是由于颏舌骨肌和颏舌肌附着点分离所致。颏结节骨折的治疗存在争议，包括不进行手术干预、切除撕脱的骨碎片以及肌肉复位。文献中仅报道了11例这种骨折，其中大多数是自发性的。我们报告了一名86岁无牙女性患者发生颏结节自发性骨折的疑难诊断情况，患者伴有疼痛的舌下和颏下血肿以及颈前部瘀斑。应进行计算机断层扫描以确诊。无需手术治疗，6个月的随访显示症状完全恢复，功能完全恢复。
