Otolaryngologists (ENT) and oral maxillofacial surgeons are commonly consulted for the evaluation of maxillary sinus fractures (MSFs).
Proper reduction of maxillary fractures is the key to achieving good dental occlusion and needs proper clinical examination of the fracture pattern after all the accessible fracture sites are exposed. The CBCT images ruled out the possibility of root fracture and showed diffuse periapical rarefaction associated with the molars and premolars in the left maxillary posterior area.

Most fractures occur in the floor posterior and medial to the infraorbital groove 2. Maxillary and Mandibular fractures occur from either direct or indirect blunt force to the facial bones. Definitions . 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. Symptoms associated with a Le Fort I fracture may include facial pain, infraorbital hypoesthesia, malocclusion, or epistaxis. Associated signs and symptoms include hypoesthesia of the infraorbital nerve distribution, trismus, and subjective malocclusion. Call +91-124-4141414 34.
