Mandibular symphysis fracture associated with the displacement of a fractured genial segment: An unusual case report with review

Traumatic genial tubercle fracture: a case description with 9-month radiographic follow-up and a literature analysis

“…Limited tongue movement was rarely reported (17). On the other side, some cases of genial tubercle fracture, including the present reported case, were left without any active surgical intervention (13,15). This was done after assuring that the patients had normal preoperative tongue movements with no associated respiratory distress.…”

“…On reviewing the medical literature, we have found 12 documented cases were reported heretofore (2,(10)(11)(12)(13)(14)(15)(16). These cases of combined mandibular fractures with genial tubercle separation were summarized (Table 1).…”

Transoral Approach to Open Reduction of a Traumatic Avulsion Fracture of the Genial Tubercle Associated With a Mandibular Symphysis Fracture: A Case Report and Literature Review

“…There have been 6 documented cases of combined fractures of the mandibular symphysis and GTFs (type II). [3][4][5][6][7] In these cases, when preoperative tongue mobility was normal, ORIF of the symphysis fractures only, leaving the genial tubercle to remain in an ectopic position yielded favorable results. 3,4 In contrast, three cases of type II GTFs had extensive floor of mouth edema, intraoral hemorrhage, and posterior displacement of the tongue causing obstruction of the parapharyngeal airway.…”

“…[3][4][5][6][7] In these cases, when preoperative tongue mobility was normal, ORIF of the symphysis fractures only, leaving the genial tubercle to remain in an ectopic position yielded favorable results. 3,4 In contrast, three cases of type II GTFs had extensive floor of mouth edema, intraoral hemorrhage, and posterior displacement of the tongue causing obstruction of the parapharyngeal airway. [5][6][7] This necessitated open reduction of GTF through either wire resuspension or screw fixation, all performed via extraoral submental skin incision.…”

“…1,2 Type II GTFs are rare with few reports in the literature. [2][3][4][5][6][7] Risk factors for type I GTF include osteoporosis, female sex, and old age. 1 In contrast, type II GTF is often due to macro-trauma leading to avulsion of the genial tubercles with sudden loss of function, swelling, and potential airway compromise.…”
