Microvascular decompression is a minimally invasive procedure that usually chooses a transverse or vertical incision behind the ear, about 4-5 cm long. Common complications of the procedure include tinnitus, dizziness, hearing changes, pharyngeal discomfort, and numbness of the incision. Most of them are related to the irritation and disturbance of the surgical operation, and most patients can recover after symptomatic treatment, while very few patients cannot recover completely. The incidence of delayed facial palsy is low and can be completely recovered with treatment. The incidence of bleeding and infection due to surgery is less than 1%. Since the small scalp nerves around the incision will be cut intraoperatively, localized scalp numbness around the incision will occur after surgery. After the incision of the occipital muscles, there will be localized pulling discomfort in the incision after the muscle healing contraction at a later stage.
