Because of an intradermal contracting hematoma on the right side, the nose was secured with tape (without a splint). They comprise fractures of the: zygomatic arch inferior orbital rim, and anterior and posterior maxillary sinus walls lateral orbital rim Epidemiology

The main reason for implant displacement is insufficient primary stability. Maxillary fractures, in particular, Lefort fractures, are also associated with significant visual problems (47%), diplopia (21%), and epiphora (37%). The patient was referring diplopia and decreased visual acuity with signs of dystopia, proptosis, and epiphora. This represents a fairly high rate of complication of these sinus fractures. . The groups were balanced in terms of demographics, location of fractures, mechanism of fracture, and time to follow-up. Non-symptomatic abnormalities of the maxillary sinus such as mucosal thickening, retention cysts, and opacification are reported to occur in up to 74% of all cases [1-6].For diagnosis of symptomatic pathologies of the maxillary sinus like retention cysts, polyps, and tumors, panoramic radiographies (PAN) are commonly used and widely available. The patient was referring diplopia and decreased visual acuity with signs of dystopia, proptosis, and epiphora. . Perforation of the Schneiderian membrane during sinus floor elevation. A fracture of the lateral maxillary sinus wall also is present. 3. With a "sinus lift", bone can be grafted under the sinus membrane increasing the height of bone.

Fracture of the maxillary tuberosity is complication associated with extraction of upper molars. The maxillary ostium was visualized and opened (septal fracture had been against this on the medial side). The increased orbital pressure simultaneously fractures the bony floor and pushes the bone fragment downward, displacing the bone into the maxillary sinus, along with soft tissue from the orbit.

The maxillary tuberosity is especially important for the stability / retention of upper dentures and may cause a mouth-sinus comminication (oro-antral communication). The pathological burst fracture of a lumbar vertebra was inferred to be the consequence of GCSF produced by the maxillary sinus SCC in this elderly patient with osteopo rosis, rather than bone metastasis, for the following reasons: An antrostomy was performed through the anterior wall of the maxillary sinus, and then digital pressure was used to reduce the orbital fracture.

Le Fort 2 fractures involve the frontonasal suture, the inferior orbital rim and floor, and the maxillary sinuses, forming a pyramidal shape. Maxillary sinusitis is a relatively rare complication of fractures of the maxilla despite frequent comminution of the walls of the sinus. CT scans are superior to plain films for delineating multiple fractures, evaluating associated cartilaginous or soft tissue injury, and assessing for the presence of impingement into the optic. The maxillary sinus is the largest of the four paranasal sinuses and, being anatomically adjacent to the dentate region of the maxilla, is commonly a source of problems - not simply in terms of . Drainage of orbital blood can be critical in the postoperative period following repair of orbital floor fractures, be it into the maxillary sinus or the outside world. The authors encourage the surgeon to take great care in ensuring sound surgical principles. These complications could occur secondary to the incarceration of periorbital tissues or muscle or later cicatrization in and around the inferior rectus muscle. . The incidence of tuberosity fractures is generally low; they occur in every 0.08% - 0.15% of simple extractions. Most of the growth of the maxillary sinus begins after the age of 5. Maxillary sinus augmentation or sinus lift surgery is a trending procedure in implant dentistry that can achieve impressive success rates for dental implantation in the posterior maxilla region.
