Nasal/sinus endoscopy with ligation of the sphenopalatine artery (SPA) is a surgical procedure designed to address severe cases of posterior epistaxis, particularly when traditional methods such as nasal packing have proven ineffective. The sphenopalatine artery, a critical vessel branching from the internal maxillary artery, plays a significant role in supplying blood to various structures within the nasal cavity, including the lateral nasal wall, turbinates, and portions of the nasal septum. This procedure not only aims to control excessive bleeding but may also be performed to facilitate vascular control in preparation for tumor excision within the nasal or sinus regions. The process involves a thorough inspection of the nasal cavity and surrounding areas using an endoscope, allowing for precise identification and ligation of the SPA to mitigate bleeding. The procedure is performed under local anesthesia, ensuring patient comfort while enabling the surgeon to effectively manage the surgical site. Following the ligation, the surgical area is carefully packed to promote healing and minimize the risk of postoperative complications.
