Facial malformation caused by unilateral elongated coronoid process: report of a case and literature review

Abstract

Abstract: Elongation of the mandibular coronoid process is a kind of abnormal presentations. It is a rare condition, and often occurs bilaterally. So far, there still is no consensus about its etiology, several hypotheses have been proposed. Diagnosis of the condition is made based on clinical signs of mouth opening limitation and facial asymmetry, imaging exams (panoramic radiography, cone-beam computerized tomography and three-dimensional computerized tomography)and histopathology. Coronoidectomy is a reliable treatment modality. This paper reported a case of facial malformation without mouth opening limitation caused by unilateral coronoid process elongation and reviewed relevant literatures.

Key words: Coronoid process elongation, Mouth opening limitation, Facial asymmetry, Coronoidectomy
