Facial blanching as a complication of local anesthesia is reported in dentistry. Inadvertent arterial penetration and subsequent vasospasm has been accepted as the mechanism of this phenomenon. Most cases occur after inferior alveolar nerve block injection. In this article, five cases are reported after Gow-Gates injection, maxillary nerve block via greater palatine foramen, inferior alveolar nerve block, and maxillary buccal infiltration. It is the largest case series in this topic. Also, clinico-anatomical correlation between facial-mucosal blanching and the site of intra-arterial injection is explained. To the best of our knowledge, partial blanching of the face subsequent to buccal infiltration is reported for the first time in this article. Cutaneous surgeon should be aware of this complication and should not carry out unnecessary treatment.
牙科领域报道了面部苍白作为局部麻醉并发症的情况。意外动脉穿刺及随后的血管痉挛被认为是这一现象的机制。大多数病例发生在下牙槽神经阻滞注射后。本文报道了5例在使用Gow-Gates注射法、经腭大孔上颌神经阻滞、下牙槽神经阻滞及上颌颊部浸润麻醉后的病例。这是该主题下最大的病例系列。此外，还解释了面部黏膜苍白与动脉内注射部位之间的临床解剖学关联。据我们所知，本文首次报道了颊部浸润麻醉后出现面部部分苍白的情况。皮肤科医生应意识到这一并发症，不应进行不必要的治疗。
