This article introduces a rare complication called Kuhn anemia during inferior alveolar nerve block (IANB). It is caused by vasospasm of the maxillary artery. Reasons such as inaccurate injection, anatomical variation, and drug diffusion may lead to this complication. Therefore, doctors should be cautious before and during the surgery.
Purpose: Introduce Kuhn anemia as a complication during the inferior alveolar nerve block (IANB). Methods: Here, the authors reported a lesser-known complication called Kuhn anemia during the IANB. Then, the authors searched and reviewed relevant literature on the Web of Science. Results: Vasospasm of the maxillary artery results in the phenomenon. Reasons, such as inaccurate injection, anatomical variation, drug diffusion, and so on, may account for the complication during the IANB. Conclusions: All in all, doctors should be prudent before and during the surgery.
