中文摘要

冠突过长(CPH)是一种罕见的下颌骨发育过程中冠突形态和长度的异常疾病,本文报道2例双侧CPH引起下颌运动及开口受限的病例资料,通过报道病例的临床表现、X线检查、治疗及预后,为该疾病的诊疗提供参考。这2例CPH病例经外科切除伸长的冠突后,即刻开口度均增加到近三指,其中1例治疗6个月后,随访开口度正常,而另外1例术后2年CPH复发。CPH的病因暂不明确,可能与多种因素相关。CPH导致开口受限的情况在临床上极其少见,易与其他疾病混淆导致误诊。因此,应综合运用临床及影像学加以鉴别诊断。外科手术切除伸长的冠突是目前公认的治疗方式,而术后长期有效的开口训练对治疗效果的维持至关重要。

英文摘要

Coronoid process hyperplasia (CPH) is a rare condition characterized by the increase in the size of the coronoid process, mainly occurring in the second decades of human life. To provide a reference for the diagnosis and treatment of this disease, we reported the clinical manifestations of two cases, X-ray examination, treatment, and prognosis with mandibular movement and restricted mouth opening (RMO) caused by bilateral CPH. The opening degree of the two cases described in the article increased to almost 40 mm immediately after the elongated coronoid process was surgically removed and a case was maintained normal after 2 months. In another case, CPH recurred after 2 years of follow-up. The etiology of CPH is still unclear, which is associated with various factors. RMO caused by CPH is extremely rare in clinical practice, and it is easy for patients to get confused and be misdiagnosed. It should be diagnosed using comprehensive methods of clinical studies and imaging modalities. Currently, surgical coronoidectomy is an accepted treatment of CPH. Long-term effective opening training is crucial in maintaining its therapeutic effect.
