To present a case of spontaneous fracture of the genial tubercles of the mandible and a review of the literature.
Resorption of the mandible is well documented in edentulous patients. During this process, the genial tubercles, origin for both genioglossus and geniohyoid muscles, become more prominent and prone to trauma especially from poorly fitted lower full dentures and lead to fracture and separation of the genial tubercles from the mandible.
An 85 year old patient with the above presentation was monitored and documented to present this case report. A literature search was carried out to identify any previous reports of this type of fracture, and their diagnosis and treatment modalities.
This case is extremely rare with only 17 cases reported in the literature.
Although rare, fractured genial tubercles should be considered in the differential diagnosis for a painful swelling in the floor of the mouth in the edentulous patient.
报告一例下颌颏结节自发性骨折病例并进行文献复习。
无牙患者下颌骨吸收已有充分文献记载。在此过程中，颏舌肌和颏舌骨肌的起点颏结节变得更加突出，尤其容易受到不合适的下颌全口义齿的创伤，导致颏结节与下颌骨骨折和分离。
对一名有上述表现的85岁患者进行监测并记录，以呈现本病例报告。进行文献检索以确定此前关于此类骨折及其诊断和治疗方式的任何报告。
该病例极为罕见，文献中仅报道了17例。
尽管罕见，但对于无牙患者口底疼痛性肿胀的鉴别诊断，应考虑颏结节骨折。
