Abstract: Microvascular decompression (MVD) is a surgical procedure for relieving pressure on the trigeminal nerve caused by offending blood vessel, done by placing cushion between the two and is considered highly effective treatment for trigeminal neuralgia (TN). DFP refer to the facial paralysis which occurs more than 24 hours after MVD procedure and it can generally recover spontaneously. It common in clinical observation and its mechanism is still unclear. Facial paralysis can result from several mechanisms which includes inadvertent injury to the facial nerve as during the MVD surgery, the facial nerve, which lies in close proximity to the trigeminal nerve, can be at risk. Even a small amount of trauma to the facial nerve can lead to temporary or permanent weakness. Post-surgical swelling or inflammation: Following MVD, the surrounding tissues, including the facial nerve, can experience swelling or inflammation. This may temporarily impair the function of the facial nerve. Anatomical variations: Variations in the anatomy of the vascular structures or the proximity of the facial nerve can increase the likelihood of facial nerve involvement during decompression. The management of post-operative facial paralysis typically involves a thorough evaluation to determine whether the condition is transient (due to inflammation or mild injury) or more persistent, which might require further intervention. Conservative treatments, such as corticosteroids or physical therapy, are often recommended for mild cases, while more severe or persistent cases might necessitate additional surgical approaches.
