The caseload of jaw osteomyelitis seem to have decreased considerably over the last fifty years thanks to the progress of oral hygiene, the appearance and the use of antibiotics, and early screening. ‘Limited osteitis’ remains frequent in general practice (alveolitis after dental extraction), but osteomyelitis is much rarer as evidenced by the lack of current literature and the low number of reported patients in the published series. The aim of this study was to analyze retrospectively all the cases of maxillo-mandibular osteomyelitis treated in a large academic department of Stomatology and Maxillofacial Surgery over a period of 6 years and to compare the results to data from the literature.
Material and method
All patients diagnosed with maxillo-mandibular osteomyelitis by one of the staff surgeons between January 2009 and December 2015 was included. An epidemiological record (sex, age, ethnic background, risk factors, clinical, origin of disease, imaging and biology, treatments and progression) were collected for each patient. Osteomyelitis cases were classified according to the Zurich Classification System. Results were compared to data from the literature.
Forty patients were retained. Three presented acute osteomyelitis, 26 secondary chronic osteomyelitis and 11 a primary chronic osteomyelitis. Osteomyelitis affected predominantly the mandible (87%). Dental origin was found in 90% of cases. Nine patients (22.5%) recovered and 29 (90%) were clinically improved. Ten of the 11 patients with primary chronic osteomyelitis were improved.
This cohort study is one of the largest series currently available and presents results comparable to those of the literature of the last 25 years.Le texte complet de cet article est disponible en PDF.
