Proposed mechanism of action for twin mix anaesthesia when used as intra-space pterygomandibular injection for inferior alveolar nerve block with emphasis on effects of perineural injection of dexamethasone

Abstract

There has been recent research on the use of dexamethasone as an adjunct to local anaesthetics to enhance the block characteristics and improve post-operative pain outcomes. Numerous studies have shown that perineural dexamethasone improves post-operative analgesia, along with other clinical benefits. Intra-space pterygomandibular twin mix anaesthesia is a novel technique for inferior alveolar nerve block used for mandibular anaesthesia. Twin mix anaesthesia has its advantages in shortening the latency and prolonging the duration of the soft tissue anaesthesia, along with improving the quality of life in the post-operative period after mandibular oral surgical procedures. The concern regarding the use of perineural dexamethasone has been discussed.
