The palatovaginal or pharyngeal artery is a small branch of the internal maxillary artery supplying the nasopharynx. Bleeding from this artery is exceptional and only one case of traumatic epistaxis from this artery has been reported previously. We report a case of a 66-year-old male presenting with right recurrent posterior epistaxis. Endoscopic dissection of the pterygopalatine fossa and direct visualization of the palatosphenoidal canal permitted to identify the origin of bleeding, and coagulation of the pharyngeal artery solved the epistaxis. Although rare, intractable posterior epistaxis may arise from the pharyngeal artery. The anatomical knowledge of this artery and of the palatosphenoidal canal is of outmost importance in endoscopic transpterygoid and nasopharyngeal procedures, to identify the vidian canal, evaluate nasopharyngeal cancer spread in the pterygopalatine fossa, reduce bleeding during surgery of the nasopharynx, and harvest adequately the pedicle of the nasoseptal flap.

Dipropyl phthalate (DPRP), a plasticizer commonly utilized in the plastics industry, has been identified in food and the environment and has the potential to present a hazard to human health and the environment. In this study, the first comprehensive evaluation of DPRP-induced craniofacial chondrogenic defects was conducted using a zebrafish model. Zebrafish embryos were exposed to 1, 2, and 4 mg/L DPRP from 6 to 96 h post-fertilization.

Velocardiofacial syndrome (VCFS), also known as 22q11.2 deletion syndrome or DiGeorge syndrome, is a complex genetic disorder associated with a spectrum of phenotypic features, including craniofacial anomalies, congenital heart defects, and neurodevelopmental challenges. Among the more concerning, though under-recognized, presentation in VCFS is carotid artery medialization-a finding that places patients at substantial risk for vascular injury during pharyngeal surgeries.

Aberrant carotid arteries are rare vascular anomalies that can significantly complicate head and neck surgeries, particularly in pediatric patients. These anomalies may be asymptomatic and are often discovered incidentally on imaging studies performed for unrelated conditions. The failure to recognize these anomalies preoperatively can result in life-threatening complications, such as catastrophic hemorrhage.

Endovascular treatment (EVT) is the first-line treatment for petrous ridge dural arteriovenous fistulas (DAVFs). However, EVT is associated with complications. Among these complications, delayed venous hemorrhage is fatal.

Introduction And Importance: Carotid body tumors are rare neoplasms originating from neural crest cells, commonly presenting as a painless, slow-growing mass in the lateral neck. The retropharyngeal variant of these tumors is particularly uncommon, with an incidence of approximately 2.6 %.
