Reduction malarplasty through the intraoral or the combined approach using intraoral and preauricular incisions is widely performed as an aesthetic surgical procedure in northeast Asia. The authors recently examined a patient who underwent this type of surgery and presented with discoloration of both upper canine teeth that was diagnosed as pulp necrosis. This case suggests the possibility that pulp necrosis occurs as a result of vibration and heat energy transmitted from a rotating bur to the anterior superior alveolar nerve branch located in the more lateral and superficial portion than in the normal position. Although pulp necrosis is extremely rare, it is hoped that this case will heighten the awareness of surgeons to this potential complication.
经口内或采用口内与耳前联合切口的颧骨缩小整形术在东北亚地区作为一种美容外科手术被广泛开展。作者最近检查了一名接受此类手术的患者，该患者出现上颌双侧尖牙变色，诊断为牙髓坏死。该病例提示，牙髓坏死可能是由于旋转牙钻传递的振动和热能作用于位于比正常位置更外侧和表浅部位的上前牙槽神经分支所致。尽管牙髓坏死极为罕见，但希望该病例能提高外科医生对这一潜在并发症的认识。
