Cervicofacial subcutaneous emphysema (CFSE) is a rare complication. CFSE may happen following some dental procedures including root canal therapy and is caused by unintentional entry of air into potential spaces of head and neck. In the current report, a case of extensive bilateral subcutaneous emphysema -following the root perforation of a maxillary anterior tooth- is presented. A 26-year-old woman was referred for further consultation concerning her right maxillary lateral incisor; for which a poor prognosis was considered following an endodontic treatment. There was a history of sudden facial swelling during root canal therapy. With the exacerbation of the problem and experiencing other symptoms, she was hospitalised. CT scan showed bilateral extension and penetration of air into submandibular, peri-orbital and parapharyngeal spaces. Clinical and radiographic evaluations of the maxillary lateral incisor revealed mid-root perforation on its buccal side, which was sealed by MTA. Eventually, the tooth was successfully restored.
颈面部皮下气肿（CFSE）是一种罕见的并发症。CFSE可能发生在包括根管治疗在内的一些牙科手术后，是由空气意外进入头颈部潜在间隙所致。在本报告中，呈现了一例上颌前牙根管穿孔后出现广泛双侧皮下气肿的病例。一名26岁女性因右上颌侧切牙前来进一步咨询；在根管治疗后，该牙被认为预后不良。根管治疗期间有面部突然肿胀的病史。随着问题加重并出现其他症状，她住院治疗。CT扫描显示空气双侧蔓延并进入下颌下、眶周和咽旁间隙。对上颌侧切牙的临床和影像学评估显示其颊侧牙根中部穿孔，用矿物三氧化物凝聚体（MTA）进行了封闭。最终，该牙成功修复。
