Hello there...Osteomyelitis of maxilla is usually seen in patients undergoing extractions with a chronic history of maxillary sinusitis or pan sinusitis. Patients with chronic sinusitis have to be treated with appropriate antibiotics as a prophylactic measure to prevent post extraction complications such as osteomyelitis being one amongst them. I have recently operated 2 cases of osteomyelitis of left maxilla with same clinical presentation. Maxillary sinus is a void space that fills up the middle part of face, just above the maxillary bone on both the sides that keeps the air humid and moist and makes the skull feel very light. It is covered by an epithelial lining that purifies the air we breathe in. In chronic cases of infections or sinusitis the lining thickens and stops functioning normally. The same way there are other sinuses such as ethmoidal, sphenoidal sinuses and so on. All of them have the same function. Owing to the infection there is accumulation of pus that gives a heavy feeling in that side of the face. This causes radiation pain over that side of maxillary teeth. Most of the dentists fail to diagnose and end up extracting the maxillary teeth. This most oftenly manifests in the form of osteomyelitis. what was the reason behind getting your teeth extracted?please mention it.... Osteomyelitis is the inflammation of the bone where bone fails to get its normal blood supply eventually leading to necrosis of the bone. That requires a surgical correction. Please consult a Oral and Maxillofacial Surgeon for clinical evaluation.
