摘要/Abstract

摘要： 冠突过长是一种下颌骨冠突形态的异常表现，其发生率低，单侧冠突过长较双侧更少见。目前其病因不明，存在几种假说。临床上主要表现为无痛性进行性开口受限和面部不对称等。诊断主要依靠临床表现、影像学资料（全景片、CBCT及3D-CT等）和组织病理学检查。最有效的治疗方法为冠突切除术。本文报告1例单侧冠突过长致面部畸形但无开口受限的病例，并对相关文献进行复习。

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
