“…The maxillary and middle meningeal arteries are especially prone to iatrogenic injury during osteotomy, fragment repositioning, screw insertion, or surgical dissection near the articular eminence (prior to insertion of a TMJ prosthesis), especially in patients with TMJ ankylosis [24][25][26][27][28][29][30]. The reference points selected for our new measurement technique are chosen to correspond to landmarks that are easily identifiable intraoperatively.…”

Purpose The close topographic relationship between vascular and osseous structures in the condylar and subcondylar region and marked variability in the arterial course has been revealed by both imaging and cadaveric studies. This study aimed to verify the previously published information in a large sample and to determine a safe surgical region. Methods We analyzed the three-dimensional time-of-flight magnetic resonance angiography images of 300 individuals. Results The mean distance between the middle meningeal artery and the apex of the condyle or the most medial point of the condyle was 18.8 mm (range: 11.2–25.9 mm) or 14.5 mm (range: 8.8–22.9 mm) respectively. The course of the maxillary artery relative to the lateral pterygoid muscle was medial in 45.7% of cases and lateral in 54.3%. An asymmetric course was evident in 66 patients (22%). The mean distance between the maxillary artery and condylar process at the deepest point of the mandibular notch was 6.2 mm in sides exhibiting a medial course (range: 3.7–9.8 mm) and 6.6 mm in sides exhibiting a lateral course (range: 3.9–10.4 mm). The distances were significantly influenced by age, gender, and the course of the maxillary artery. Conclusion Our study emphasizes the marked inter- and intra-individual variability of the maxillary and middle meningeal arterial courses. We confirmed the proximity of the arteries to the condylar process. Extensive surgical experience and thorough preparation for each individual case are essential to prevent iatrogenic vascular injury.

“…Angiography allows location of the site of bleeding and determination of the architecture of the blood vessels [ 7 , 14 , 18 ]. The differential diagnosis was an arteriovenous fistula, which is associated with continuous sound [ 19 ]. Pseudoaneurysm should also be differentiated from hematoma, abscess, and inflammatory lymph node, cyst, and neoplastic tumor [ 7 , 18 ].…”

“…Embolization of pseudoaneurysms in the head and neck region is also used in the treatment of epistaxis, post-traumatic hemorrhage, and preoperative revascularization of a tumor [ 7 ]. Materials for embolization of endovascular lesions in the head and neck include metal coils, polyvinyl alcohol, n-butyl cyanoacrylate (NBCA), polymers, or absorbable sponge gels [ 19 ]. Titanium coils are positioned proximally with regard to the pseudoaneurysm and distally to the normal vessel [ 5 ].…”

Bilateral Maxillary Pseudoaneurysms as a Complication of Craniofacial Fracture: A Case Report

Patient: Male, 16-year-old Final Diagnosis: The bilateral maxillary pseudoaneurysms Symptoms: Pain • paresis • swelling Medication: — Clinical Procedure: Embolization Specialty: Dentistry • otolaryngology Objective: Rare disease Background: Pseudoaneurysms of the head and neck region are relatively rare and consequently there are few reports in the literature. The main causes of pseudoaneurysms in the head and neck area are associated with blunt or penetrating injuries in this area or are iatrogenic, originating during surgical procedures. Case Report: The authors illustrate a case of a 16-year-old boy who had an accident on a scooter. A maxillary artery hemorrhage occurred after multiple craniofacial trauma including bilateral fracture of the condylar processes and treatment with intravascular embolization. Due to the anatomical location of the injury and deep location of the maxillary artery, it was impossible to control the bleeding by direct pressure; the only option was vessel embolization using interventional radiology or surgical intervention. The authors describe symptoms of pseudoaneurysm: pain in the area of the temporomandibular joint on the left side, persistent bilateral swelling of the cheeks and parotideomasseteric region with a greater asymmetry on the left side, as well as peripheral paresis of the facial nerve on the left side. The diagnosis was based on magnetic resonance imaging, ultrasound, and angio-CT. A reduction in the clotted pseudoaneurysm size on the left side was confirmed after 6 and 10 months through monitoring ultrasound examination of the neck vessels. Conclusions: No similar case of a patient has been reported in the available literature. The development of bilateral pseudoaneurysms after injury is very rare. However, doctors should be alert to this possibility in the case of massive post-traumatic or postoperative bleeding.

“…Endovascular approach involves either the use of materials to occlude vessel lumen or the placement of a stent. Numerous agents have been used for the embolization therapy such as metallic coils, polyvinyl alcohol particles, n-butyl cyanoacrylate (NBCA), polymers (Onyx, SQUID), and absorbable sponge gel [9].…”

Pseudoaneurysms are rare lesions secondary to blunt or penetrating trauma, temporomandibular joint surgery, or orthognathic surgery. They are usually produced by arterial breach leading to extravasation of blood. The compressed perivascular tissue forms the wall of aneurysmal sac. This sac gradually expands and can be damaged. Nonsurgical interventions are the treatment of choice for pseudoaneurysms. In the case reported here, emergent endovascular injection of acrylic glue was successful in the treatment of a pseudoaneurysm from a branch of the internal maxillary artery secondary to surgical extraction of impacted maxillary third molar.
