     Decortication has been employed with satisfactory results. Intraoral decortication with immediate soft tissue closure followed by pressure bandages places vascular tissue in contact with the decorticated medullary bone that has been deprived of its physiological blood supply. In reestablishing an available blood supply, antibiotic therapy may be expected to be of greater value. Hjorting-Hansen has described in detail decortication of the mandible in the treatment of osteomyelitis.
     The decision whether to extract excessively mobile teeth in the segment of the jaw where suppuration is visible around the gingiva is another point of controversy and one that requires the keenest discretion and judgment. Some of the most spectecular suppurative and rampant cases can
Apparently reach a crisis; at which point symptoms will subside and regeneration begin without the extraction of mobile teeth. The offending tooth, of course, is usually extracted.
     Drainage incisions for osteomyelitis have a tendency to proliferate large amounts of granulation tissue, which will expel artificial drains from the wounds. Unless retained with mattress sutures over the dressings, drainage gauze that is packed into the wound may become extruded. Suturing of the drainage material may be necessary to maintain its position so that the wound remains saucerized. This procedure pertains to both intraoral and extraoral wound dressings. The retention of dressings that maintain saucerization of the wound for intervals of 5 to 7 days without replacement is recommended unless clinical symptoms indicate intervention.
     Topazian and Goldberg have authored an indepth text on management of oral and maxillofacial infections, which the reader may find a valuable source of current knowledge on the subject.
