The duration of jaw surgery, also known as orthognathic surgery, can vary depending on the complexity of the case. On average, the procedure typically takes around 1 to 3 hours to complete. However, more intricate cases may require longer surgical times. The surgeon will carefully plan the surgery beforehand, considering various factors to ensure a successful outcome. Nonetheless, It's essential to discuss the estimated duration with your oral and maxillofacial surgeon during the pre-surgical consultation to clear any doubts.
