If a patient experiences a sigmoid notch bleed after IVRO, what is the recommended treatment?

• A. Direct suturing of the vessel
• B. Embolization of the masseteric artery
• C. Application of cold compresses
• D. Antibiotic therapy

Answer: (B)

In cases of sigmoid notch bleeding following an intraoral vertical ramus osteotomy (IVRO), the recommended treatment involves embolization of the masseteric artery. This approach is preferred because the sigmoid notch is closely associated with the vascular supply from the masseteric artery. Embolization serves to selectively occlude the blood vessel that is bleeding, thereby stopping the hemorrhage and minimizing the risk of further complications associated with bleeding. Direct suturing of the vessel can be challenging due to the deep anatomical location of the bleeding site and may not be feasible or effective in controlling the bleed. Applying cold compresses may provide minimal temporary relief but does not address the underlying cause of the bleeding and is unlikely to be sufficient for significant vascular injury. Antibiotic therapy, while important in preventing infection post-operatively, does not have any direct effect on managing an active hemorrhage. Thus, performing an embolization is the most direct and effective treatment option in this scenario.
