Neocondylar Formation with Vascularized Fibular Free Flap: A Report of Three Rare Cases and Review of Literature

Background: Neocondylar formation is an uncommon finding that can result after the reconstruction of a vascularized free flap. Three case reports were presented in the current article. (1) A 64-year-old male presented with clear cell Odontogenic Carcinoma to the left mandible. (2) A 14-year-old male presented with an ameloblastoma to the right mandibular associated with tooth 48. (3) A 13-year-old female presented with an ameloblastoma to the right mandible. Methods and Results: All three cases required a surgical resection of the mandible involving the temporomandibular joint. Reconstruction was performed using a vascularized free flap, and Neocondylar formation was observed during the healing process in all three cases. Neocondylar formation after a vascularized free flap reconstruction can improve anatomical functions such as mastication and decrease post-operative complications. Knowledge of this finding can improve future surgical treatment planning and outcome. Conclusion: This report contributes to the existing literature by offering new insights into neo-condylar formation following mandibular reconstruction with vascularized free fibular flap, particularly in complex resective surgeries, and highlights its potential clinical implications.
