Introduction
Osteomyelitis describes an inflammation of the entire bone, including the bone marrow and the periosteum, cortical, and cancellous parts of the bone.1 A common infectious cause of osteomyelitis is inflammation of the bones. In 1847, Rees described maxillary osteomyelitis.2 The mandible is more likely than the maxilla to develop osteomyelitis because of the latter's lower risk of infection because of its wide collateral blood flow, thin cortical bones, and dispersed bone marrow.3, 4 Osteomyelitis was rather common prior to the development of antibiotic therapy. It was an illness that might be fatal before the discovery of antibiotics; however, if handled effectively in the modern period, it can, resolve satisfactorily.5 Here, we report a rare case of an elderly patient with maxillary osteomyelitis.
Case Report
A 55 year old male patient reported to the Department of Oral and Maxillofacial Surgery, Thai Moogambigai Dental College and Hospital, Chennai, complaining of swelling for the past two weeks on the right side of his face. He had a history of slight pain which was dull in nature that got worsened on having food but relieved on medications. The patient visited the dental clinic 4 months prior for the same complaint, where he underwent uneventful extraction and root canal treatment in the upper right back tooth region along with antibiotic coverage and was prescribed medication on and off due to pain and swelling for a period of 4 months. There was no gross facial asymmetry visible during extraoral examination. Palpation revealed a slight tenderness over the right maxillary sinus region. Intra-oral examination revealed a lesion appearing as an exposed bony sequestrum and missing 14,15 (Figure 1, Figure 2).

On radiographical examination, IOPA revealed the extraction socket with respect to regions 14 and 15. OPG revealed radiopacity in the right maxillary sinus (Figure 3). Evident intertrabecular bone formation noted in relation to the 14 and 15 extraction sockets. CT revealed bony destruction in the right maxillary sinus (Figure 4).

Surgical intervention was planned under local anaesthesia. The next day, patient underwent local anaesthesia and the extraction of 16, 17, and complete excision of sequestered bone were done (Figure 5). Complete curettage of the lesion was performed and wound toileting was done using betadine and regular saline. Roller gauze soaked with bismuth oxide paste was used to fill the cavity, with the end of the gauze left outside. 3-0 vicryl sutures were used to approximate the flaps. Regular dressing and irrigation was done and post operatively followed by inj. Clindamycin 600mg i.v. 6 hourly for 5 days and then clindamycin capsules 300mg 6 hourly for 7 days. Regular follow up showed satisfactory results (Figure 6, Figure 7 ).
Discussion
The term "maxillary osteomyelitis" refers to osteomyelitis of the maxilla, which is an inflammation of the entire bone, including the periosteum, bone marrow, cortical and cancellous bones. This condition was life threatening prior to the development of antibiotic therapy.6, 7, 8 The British doctor Sir Benjamin Brodie wrote the first report on osteomyelitis in 1832.9 Osteomyelitis can be caused by bacterial infections, with common pathogens, including Staphylococcus aureus, Streptococcus, and anaerobic bacteria.10 Clinical features may include pain, swelling, redness, and warmth around the affected area of the face. Intraoral symptoms can manifest as gum swelling, tooth mobility, and purulent discharge. In our patient, pain and swelling over the hard palate were observed.
Clinical evaluation, imaging studies (CT scans, MRI), and sometimes dental X-rays are used to diagnose maxillary osteomyelitis. On panoramic radiographs, an irregular or moth-eaten appearance of the maxillary bone, and increased density in the affected area due to new bone formation as a response to infection and thinning or perforation of the cortical bone are also observed. CT provides more detailed and three-dimensional images than panoramic radiographs. The presence of lytic lesions or areas of bone destruction and the formation of sequestra within the affected bone are observed. MRI is effective in visualizing soft tissue involvement, including the presence of abscesses. Additionally, a combination of imaging techniques may be utilized to provide a comprehensive assessment of maxillary osteomyelitis.
Antibiotics are a crucial component of maxillary osteomyelitis treatment. In order to remove dead bone tissue and drain abscesses, surgery could be required, or address any underlying dental or sinus issues contributing to the infection. In our case, the patient was treated with a course of antibiotics combined with surgical intervention and regular follow up.
Conclusion
Maxillary osteomyelitis is rare condition linked to extensive antibiotic usage, prompt diagnosis, and treatment. With prompt and appropriate treatment, many cases of osteomyelitis can be successfully resolved. However, delays in diagnosis or inadequate treatment may lead to chronic infections, bone damage, and complications. The severity of the illness, the patient's general condition, and the efficacy of the selected course of therapy are some of the variables that affect the prognosis.
