Abstract

Genial tubercle fracture (GTF) is rare and represents a diagnostic challenge as plain film radiography often fails to identify the fractured segment. Traumatic avulsion of the genial tubercle in conjunction with mandibular symphysis fracture may lead to posterior displacement of the tongue with the potential for airway compromise and difficulty in speech and swallowing due to loss of tongue anterior suspension. Fine cut computed tomography (CT) scan is required to confirm the diagnosis and assist further management. To our knowledge, all published cases of surgical intervention in the management of avulsed genial tubercle combined with fracture of the mandibular symphysis used an extraoral approach via submental skin incision to expose the fractured segment. To the authors' knowledge, this is the first report to describe a transoral approach in the surgical management of GTF associated with a mandibular fracture.
