An unusual case of total maxillary sequestration in a diabetic patient

Resum

Osteomyelitis of the jaw is of relatively low incidence. Maxillary Osteomyelitis is however rare compared with mandibular osteomyelitis. The extensive blood supply and the strut-like bones of the maxilla make it less prone to chronic infections. Systemic conditions that alter the host’s resistance such as diabetes mellitus, autoimmune disorders, agranulocytosis, anaemia, especially sickle cell anaemia are predisposing factors for the development of this condition. An unusual case of chronic maxillary osteomyelitis induced by trauma in a diabetic, with subsequent atypical necrotising ulceration of palatal mucosa resulting in total maxillary sequestration is presented.

Keywords: Maxillary osteomyelitis, sequestration, diabetes mellitus

Résumé
L’ostéomyelite de la joue a une incidence relativement faible. L’ostéomyelite du maxillaire est cependant rare comparé á l’ostéomyelite mandibulaire. L’innervation en sang et la nature des os du maxillaire font d’elles la réduction en infections chronique. Les conditions systémique qui alternent la résistance de l’organisme telsque le diabete mellite et les désordres autoimmunitaire, l’agranulocytose, l’anémie specialement l’anémie drépanocytaires sont les facteurs prédisposant le developement de cette condition. Un cas non habituel d’ostéomyelite chronique maxillaire induit par le traumatisme chez un diabétique avec une ulcération non typique de la mucose pallate résultant á une sequestration maxillaire totale est presentée.
