Remodelling surgery with 3D printed patient specific surgical guides in patients with chronic diffuse sclerosing osteomyelitis/tendoperiostitis of the mandible, a case series

Abstract

Background Patients with chronic diffuse sclerosing osteomyelitis/tendoperiostitis (DSO/TP) of the mandible may complain about facial asymmetry as a result of mandibular deformity, one of the characteristics of DSO/TP of the mandible. If the disease is fully extinguished, remodelling surgery could be performed to treat complaints of facial asymmetry. This study reports the results of remodelling surgery with three-dimensional (3D) designed- and -printed patient-specific surgical guides. Material and Methods 3D printed guides were designed and manufactured by using mirroring of the contralateral non-affected mandible. Subsequently, the surgical procedure was performed under general anaesthesia using these surgical guides. Results Four patients (all female) aged 15 (±2.8) years were included. They all complained about facial asymmetry and were planned for surgery with patient-specific surgical guides. Three of those surgeries were performed, of which two patients were satisfied with the result and the other patient is planned for re-surgery because of persistent aesthetical complaints. The last patient cancelled her surgery, because she eventually accepted her asymmetry with the help of a psychologist. Conclusions The use of patient-specific surgical guides in remodelling surgery of the mandible could enable a more predicTable and symmetrical outcome, which could minimise the chance for re-surgery and could increase patient satisfaction. Furthermore, it could minimise the chance of iatrogenic damage to the inferior alveolar nerve. Key words: Diffuse sclerosing osteomyelitis, chronic tendoperiostitis, pain, surgery, remodelling, 3D.
