The incidence of coronoid fractures is reported to be 1-2% in all facial fractures (1). Etiological factors are stated to include traffic accident, fall, attack, third molar tooth extraction and sagittal split osteotomy (2-4). Coronoid fractures are usually simple and linear and have little displacement. If the periosteum is injured, this displacement rate may increase with the contraction of the temporal muscle (3). Its definite diagnosis is established by considering patient history, clinical examination and radiographic examination. Although conservative approaches are generally used in its treatment, surgical intervention is rarely required (5). In this report, a case of isolated coronoid process fracture and its treatment was presented with the review of the literature.
