“…In severe midface trauma, epistaxis usually occurs immediately after facial injury, including Le Fort II and III fractures 34 . Nasal bone fractures usually result in minor epistaxis, which resolves spontaneously.…”

Cochrane Library databases was performed, focusing on studies published until April 2020. We combined the MeSH (Medical Subject Headings) terms "epistaxis," "nose bleeding," and "hemorrhage" with "dental interventions," "dental implants," "'Le Fort osteotomy," "supernumerary tooth," "blood disorders," "odontogenic tumors," and "maxillofacial trauma." Results were checked for duplicates, and titles, abstracts, and full texts were evaluated to exclude irrelevant articles. We finally included 48 studies in our review. Studies were included regardless of type (review articles, original research, case reports). The inclusion criteria were determined

“…These defects can occur in consequence of trauma (e.g. midface) [ 1 , 2 ], chronic infections (e.g. osteomyelitis, chronic oroantral fistula) [ 3 , 4 ], or iatrogenic (e.g.…”

“…The example of midface trauma in particular shows that the anatomical and functional complexity in this region often poses a major reconstructive challenge. This is already shown by the fact that there is no “one” midface fracture, but for functional reasons, a distinction is made between central midface fractures (naso-ethmoidal complex, frontal sinus, etmoid, orbita), Le Fort fractures, lateral midface fractures (zygomatic bone, zygomatic arch), and panfacial fractures [ 1 ]. Here, highly complex, three-dimensional bone structures meet, which can be loaded in different ways and are therefore difficult to reconstruct.…”

Composite grafts made of polycaprolactone fiber mats and oil-based calcium phosphate cement pastes for the reconstruction of cranial and maxillofacial defects

Objectives Synthetic bone substitutes which can be adapted preoperatively and patient specific may be helpful in various bony defects in the field of oral- and maxillofacial surgery. For this purpose, composite grafts made of self-setting and oil-based calcium phosphate cement (CPC) pastes, which were reinforced with 3D-printed polycaprolactone (PCL) fiber mats were manufactured. Materials and methods Bone defect models were acquired using patient data from real defect situations of patients from our clinic. Using a mirror imaging technique, templates of the defect situation were fabricated via a commercially available 3D-printing system. The composite grafts were assembled layer by layer, aligned on top of these templates and fitted into the defect situation. Besides, PCL-reinforced CPC samples were evaluated regarding their structural and mechanical properties via X-ray diffraction (XRD), infrared (IR) spectroscopy, scanning electron microscopy (SEM), and 3-point-bending testing. Results The process sequence including data acquisition, template fabrication, and manufacturing of patient specific implants proved to be accurate and uncomplicated. The individual implants consisting mainly of hydroxyapatite and tetracalcium phosphate displayed good processability and a high precision of fit. The mechanical properties of the CPC cements in terms of maximum force and stress load to material fatigue were not negatively affected by the PCL fiber reinforcement, whereas clinical handling properties increased remarkably. Conclusion PCL fiber reinforcement of CPC cements enables the production of very freely modelable three-dimensional implants with adequate chemical and mechanical properties for bone replacement applications. Clinical relevance The complex bone morphology in the region of the facial skull often poses a great challenge for a sufficient reconstruction of bony defects. A full-fledged bone replacement here often requires the replication of filigree three-dimensional structures partly without support from the surrounding tissue. With regard to this problem, the combination of smooth 3D-printed fiber mats and oil-based CPC pastes represents a promising method for fabricating patient specific degradable implants for the treatment of various craniofacial bone defects.

“…These fractures can be caused by motor vehicle accidents, domestic disputes, falls, industrial accidents, or assaults with or without a weapon [ 1 - 5 ]. When a midfacial fracture is accompanied by a maxillary sinus fracture, potential complications may include orbital muscle entrapment, orbital cellulitis, orbital abscess, enophthalmos, hypophthalmos, sinusitis, sinus mucocele, pseudoaneurysm, oromaxillary fistula, dental malocclusion, epistaxis, facial asymmetry, chronic facial pain, pressure sensitivity, and infraorbital nerve paresthesia [ 2 , 3 , 6 , 7 ].…”

Background: Midfacial fractures frequently involve the maxillary sinus, leading to maxillary sinus pathology. We aimed to examine the incidence and contributing factors of maxillary sinus pathology in patients who underwent open reduction and internal fixation (ORIF) for midfacial fractures.Methods: A retrospective analysis was conducted on patients who underwent ORIF for midfacial fractures at our department over the past 10 years. The incidence of maxillary sinus pathology was identified clinically and/or by computed tomography findings. Factors that significantly influenced the groups with and without maxillary sinus pathology were examined.Results: The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was found to be 11.27%, with sinusitis being the most common pathology. Maxillary sinus pathology was significantly associated with the presence of a blowout fracture involving both the medial and the inferior orbital walls. Factors such as sex, age, diabetes mellitus, hypertension, smoking, inflammatory disease, follow-up period, use of absorbable plates, and use of titanium plates did not have a significant impact on the development of maxillary sinus pathology.Conclusion: The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was relatively low, and in most cases, it resolved without the need for specific treatment. Consequently, there may not be a significant need for concern regarding postoperative maxillary sinus pathology.
