Isolated Non-Traumatic Bilateral Coronoid Process Fracture of the Mandible

Isolated bilateral fractures of the coronoid processes of the mandible occurred in this patient without any significant trauma. The definite etiology of this case is unknown, but possible causes or contributing factors may include acute reflex contraction of the patient’s temporalis muscles leading to bilateral stress fractures, coronoid process hyperplasia, or the patient’s long-term use of omeprazole. The planned treatment for this patient included pain control with Mobic and tramadol and splint fabrication followed by arch bar placement with training elastics for six weeks.
