Which bone graft source is the least likely to result in donor site morbidity for mandibular reconstruction?

• A. Rib
• B. Radius
• C. Fibula
• D. Hip

Answer: (C)

The choice of the fibula as the bone graft source that is least likely to result in donor site morbidity for mandibular reconstruction is well-founded due to several clinical and anatomical considerations. Fibula grafts are particularly advantageous in oral and maxillofacial surgery because they can be harvested with minimal disruption to the surrounding soft tissue structures and are associated with a quicker recovery. The fibula can also be harvested with its accompanying vascular bundle, allowing for a well-vascularized autogenous graft, which enhances the success of the graft integration into the recipient site. In comparison, using the rib as a graft source can result in significant discomfort and complications such as pneumothorax or chronic pain at the harvest site. Similarly, the radius, while a viable option, poses risks related to functional loss in the upper extremity, which can be significant, especially for patients who depend on their upper limbs for daily activities. Harvesting from the hip, or iliac crest, can lead to issues such as hip pain and gait disturbance, which may persist long after the surgery, making it a less ideal donor site for many patients. Hence, the fibula stands out as the best option due to its favorable morbidity profile and the additional benefits it provides in terms of
