Mandibular fractures are usually treated by general anesthesia for surgical incision and repositioning, and there are two types of anesthesia, including local anesthesia and general anesthesia. The treatment of mandibular fracture after local anesthesia is more painful and painful for the patient and is usually done by general anesthesia. General anesthesia, also known as intravenous inhalation complex anesthesia, is administered in two ways, including transoral intubation and transnasal intubation. In patients with mandibular fractures, the anesthesiologist must be required to intubate via the nasal cavity, with the tracheal tube passing through the nasal cavity to the pharyngeal cavity and finally into the trachea through the voice box. This technique of transnasal intubation is more demanding for the anesthesiologist. If the mandibular fracture is done by local anesthesia, the patient will be more painful. With the current improvements in medical devices and advances in medications, the patient can achieve painless and safe results after going through general anesthesia.
