This case report discusses the unusual presentation of limited mouth opening as a result of bilateral coronoid process hyperplasia.
A 14.5-year-old male patient of white Caucasian ethnicity presented with limited mouth opening, mandibular asymmetry, and dental crowding. Investigations confirmed bilateral coronoid process hyperplasia and management involved bilateral intraoral coronoidectomy surgery under general anaesthesia, followed by muscular rehabilitation. Mouth opening was restored to average maximum opening within 4 months of surgery.
Limited mouth opening is a common presentation to medical and dental professionals. The rare but feasible diagnosis of coronoid impingement syndrome should not be overlooked.
本病例报告讨论了双侧冠状突增生导致的张口受限这一不寻常表现。
一名14.5岁的白种男性患者出现张口受限、下颌不对称和牙列拥挤。检查证实为双侧冠状突增生,治疗包括在全身麻醉下进行双侧口内冠状突切除术,随后进行肌肉康复治疗。术后4个月内张口度恢复到平均最大开口度。
张口受限是医疗和牙科专业人员常见的症状表现。不应忽视罕见但可行的冠状突撞击综合征的诊断。
