Abstract
We report a 34-year-old man who received a penetrating injury with a rod about 3 cm in diameter that pierced the lower left jaw and entered the oral cavity. Since bleeding continued from the lower left jaw and oral cavity, emergency CT was performed, revealing extensive hematoma around the jaw. Emergency surgery was performed to remove the hematoma and arrest the bleeding. During the operation, a hematoma was found beneath the platysma muscle, the submandibular gland was completely ruptured, and continuous bleeding from the submandibular gland parenchyma was seen through a communication between the gland and the oral cavity. The submandibular gland was completely resected and the opening into the oral cavity was closed with absorbable sutures. The neck wound was left open, and tracheotomy was subsequently performed. The open wound was cleaned daily with 0.02% povidone iodine solution and continuous aspiration was done through the cervical drain. He also received short-term steroid therapy and antibiotics. The postoperative course was good and he was discharged on Day 24 after surgery.
