Diplopia after inferior alveolar nerve block anesthesia: report of 2 cases and literature review

Abstract

Inferior alveolar nerve block (IANB) anesthesia is one of the most common procedures in the dental clinic. Although this procedure is well known for its safety, complications can still occur. An ocular complication such as diplopia, loss of vision, or ophthalmoplegia is very rare, but once it happens, both the dentist and patient can be perplexed by the unexpected circumstance, and the doctor-patient trust may be harmed. We experienced 2 cases of diplopia after IANB anesthesia. This report describes the cause and diagnosis of the associated symptoms and includes a review of the literature.
