  • Functional and esthetic recovery through reconstruction of the oral and maxillofacial system is important for patients who underwent mandibulectomy due to lesions such as oral cancer. The fibula free flap, which is frequently used in the reconstruction of the mandible, is easy to prosthetic restoration with implant placement. However, patients with growing periods have difficulty in treatment with implants when the size of the fibula is small and residual growth remains. This case is an 11-year-old female patient who underwent mandibulectomy due to osteosarcoma and reconstruction of the mandible using a fibular free flap. Functional and esthetic recovery were obtained through prosthetic restoration using implant-supported fixed prostheses. Implantation site, number of implants, and type of prostheses were considered. Implant-supported fixed prostheses were delivered at 13 years old, and after an additional 1 year observation, stable results were obtained. However, observing changes in the maxillofacial system through further examinations is necessary.

  • None of the reports of delayed infection mentioned a latent period exceeding 13 months. we report an infection that developed 18 months after implantation of an absorbable plate. A 16-year-old adolescent girl had undergone reduction and fixation with an absorbable plate for Lefort I and zygomaticomaxillary complex fractures 18 months prior at our hospital. In her most recent hospital visit as an outpatient, abscess was observed in periocular area. Computed tomography revealed sinusitis with an abscess above the infraorbital rim. Wound culture yielded methicillin-resistant Staphylococcus aureus. Despite conservative treatments, wound state did not improve. Therefore, our department decided to perform surgery. Absorbable plate had been mostly absorbed but remained a bit. Bony depression of infraorbital rim and mucosal exposure of maxillary sinus anterior wall were observed. After the surgery, the patient recovered. We believe that the reason the wound infection and sinusitis manifested at the same time is because of several factor such as alcohol abuse, smoking, and mucosal exposure of maxillary sinus anterior wall. Absorbable plate takes 9 months to 3 years to be completely absorbed, thus we suggest studies with a follow-up of at least 3 years be undertaken to determine the outcomes of patients with many risk factors.
