Upper jaw chronic osteomyelitis. Report of four clinical cases.

Resumen

Osteomyelitis is an inflammatory bone disease  commonly related to an infectious origin caused by germs, mainly pyogenic staphylococcus, and occasionally,  streptococci, pneumococci  and enterobacteriae. Several treatments and classifications for osteomyelitis  have been established. These are based on clinical course, pathologic-anatomical or radiologic features, etiology and pathogenesis. Chronic osteomyelitis is a complication of non-treated  or inadequately treated acute osteomyleitis . It can also be caused  by a low grade  prolonged inflammatory reaction.

This study presents four cases of maxillary osteomyelitis treated between 2007 and 2009. Cases were treated with antimicrobial therapy. Preoperatively, patients were prescribed  Clindamycin, 300 mg. every eight hours, Cefriaxone, 1 gr. IV every 12 hours. Cases were surgically treated with subtotal hemi-maxillectomy. Postoperatively, cases were treated with Penicillin G 800,000 units IM per day, for 30 days. All cases evolved satisfactorily without relapse.
