Abstract
Sagittal split ramus osteotomy (SSRO) is a widely performed orthognathic surgery; however, among the various reported complications of SSRO, pseudoaneurysms are rarely reported. Pseudoaneurysms are rare vascular lesions formed by damage to the arterial wall that can occur after trauma or postoperatively, causing uncontrolled bleeding. The present report describes a case of a pseudoaneurysm that occurred after SSRO in a 22‑year‑old female patient. Le Fort I osteotomy and bilateral SSRO were performed under general anesthesia to improve the gummy smile and mandibular asymmetry of the patient. While osteotomizing the medial side of the left SSRO, major bleeding occurred from the soft tissue of the posterior margin of the mandibular branch. Direct compression with gauze and a local hemostatic agent stopped the bleeding. Immediately after returning to the ward, bleeding was observed from the left wound site and marked swelling of the left buccal area occurred. Contrast‑enhanced computed tomography revealed a pseudoaneurysm of the left superficial temporal artery (STA). Subsequently, arterial embolization for the pseudoaneurysm was performed. Overall, the present report describes a rare case of pseudoaneurysm of the STA as a postoperative complication of SSRO.
矢状分支截骨术(SSRO)是一种广泛应用的正颌手术;然而,在SSRO的各种并发症中,假性动脉瘤的报道很少。假性动脉瘤是一种罕见的由动脉壁损伤形成的血管病变,可在创伤后或术后发生,引起无法控制的出血。本报告描述了一个22岁的女性患者在SSRO后发生假性动脉瘤的病例。在全身麻醉下行Le Fort I型截骨术和双侧SSRO,以改善患者的牙龈微笑和下颌不对称。在左侧SSRO内侧截骨时,下颌骨分支后缘软组织发生大出血。直接用纱布和局部止血药压迫止血。返回病房后,立即发现左侧伤口出血,左侧颊区出现明显肿胀。增强计算机断层扫描显示左侧颞浅动脉(STA)假性动脉瘤。随后,对假性动脉瘤进行动脉栓塞。总的来说,本报告描述了一例罕见的STA假性动脉瘤作为SSRO的术后并发症。
