The term osteomyelitis of the jaws identifies different pathological patterns characterized by the involvement of the cortical bone and bone marrow in osteoarticular infections.At the head and neck level, the segment most affected by osteomyelitis is the mandible and in most of the cases the cause of the infection is bacterial, as a result of pulp or periodontal infections, post-extraction alveolitis, foreign bodies and fractures. The mandibular PCO often presents with an insidious onset, without a striking acute phase, and it is characterized by recurrent episodes of pain, swelling, lockjaw, latero-cervical lymphadenopathy, without signs of suppuration.Three patients have been collected and recorded for the study.The authors believe that in the more advanced cases of PCO in adult patients, in which the mandibular bone appears almost entirely sclerotic and deformed, and that are not responsive to pharmacological therapy or to conservative surgical therapies such as decortication, it is necessary to perform a complete removal of the portion affected by osteomyelitis, with lower alveolar nerve preservation and contextual reconstruction with free microvascular bone flap.Our review aims to describe the clinico-pathological features of a rare pathological entity, propose a surgical treatment algorithm using computer-aided-design/computer-aided manufacturing technology and review the existing literature.
