“…The bioink functionality was improved by the incorporation of BPs and the utilization of autologous BPs in dental and orthopedic applications is a very common treatment option when sufficient bone is present. [ 70,71 ] The BPs are produced by milling bone tissues (larger bone volume defect) or by scoring or drilling into existing bone (in the case of small bone volume defect) [ 72,73 ] which is consistent with the method utilized in the present study further exemplifying the clinical potential of the technique. In the context of large bone defect healing, the utilization of autogenous bone can be impeded by tissue availability as conventional grafting techniques consist in packing a large amount of autogenous bone in order to fill the bone defect.…”

Although bioinks with both high printability and shape fidelity while maintaining high cell viability are developed, the biofunctionality of the resulting bioprinted construct is often overlooked. To address this, a methacrylated gelatin (GelMA)-based bioink biofunctionalized with bone particles (BPs) is developed as a personalized treatment strategy for bone regeneration. The bioink consists of incorporating BPs of various sizes (0-500 µm) in GelMA at various concentrations (ranging from 5 to 15% w/v). The printability of the bioink is systematically investigated and it is demonstrated that a 15% w/v BP-loading results in high print quality for 10% and 12.5% GelMA concentrations. Rheological evaluation reveals a strong shear thinning behavior essential for printing and a high gel strength in bioink with 15% w/v 0-500 µm BPs for both GelMA concentrations. In addition, the printability of the bioink and the metabolic activity of the resulting scaffolds are dependent on both the concentration of hydrogel and size of the BPs. Importantly, the cells initially contained in the BPs are able to migrate and colonize the bioprinted scaffold while maintaining their capacity to express early osteogenic markers. This study demonstrates the feasibility of bioprinted viable BPs and may have some potential for chairside clinical translation.

“…Internal maxillary mandibular fixation (IMF) with arch bars and wires is done. Extra oral approach is proceeded left submandible incision then layer by layer dissection was performed and exposed the mandible and removed the callus reduce the fractured bones then secured plates and screws and closed the wound in layer [4][5][6][7][8]. The IMF released and checked the occlusion and explored the gunshot wound on the left maxillary region during the procedure from big defect in maxilla bleeding but was not significant controlled with surge cell and gel foam and buccal rotating flap and closed patient then the left facial bullet fistula removed and closed (Figure 2).…”

Internal maxillary artery injury is life threatening injury. It needs immediate intervention to save victim life. This case is very unusual because the intervention was not definite but was saving the patient life. This went for all most two months. The surgical challenges to have definite treatment for the internal maxillary artery injury needs very well experience Oral and Maxillofacial or head and neck surgeon with very well-trained team. Bullet is distractive mechanism for both hard and soft tissues.

“…The anatomic location of the internal maxillary artery (IMAX), deep to the parotid gland, mandibular ramus, and in the pterygopalatine fossa, usually protects the vessel from injury. Pseudoaneurysms of the IMAX are usually secondary to blunt or penetrating trauma, temporomandibular joint surgery, or orthognathic surgery 456. This report discusses diagnosis and treatment of a partially thrombosed IMAX pseudoaneurysm.…”

Although digital subtraction angiography (DSA) is the gold standard for pseudoaneurysm diagnosis, computed tomography angiography (CTA) may provide complimentary information, as seen in this case.…”

A 29-year-old man arrived in our emergency department after being shot on the face. Computed tomography (CT) revealed multiple facial bone fractures along the bullet trajectory. On day 10 of admission, CT angiogram of the neck revealed a partially thrombosed pseudoaneurysm in the parapharyngeal fat pad. The pseudoaneurysm was successfully treated with coil embolization. This report discusses diagnosis and treatment of a partially thrombosed internal maxillary artery pseudoaneurysm. Although digital subtraction angiography is the gold standard for pseudoaneurysm diagnosis, CT angiography may provide complimentary information, as seen in this case.
