Late Donor-Site Complications Following Free Fibular Flap Harvest: A Report of a Rare Case.

Mandibulectomy with free fibular flap reconstruction is a well-established procedure in head and neck surgery, recognized for its functional and aesthetic outcomes. However, this procedure carries certain risks, including the rare occurrence of late-onset donor site morbidities such as compartment syndrome. We report the case of a 67-year-old male with multiple comorbidities who developed compartment syndrome due to delayed hematoma formation at the donor site after undergoing segmental mandibulectomy with left fibular osteocutaneous free flap reconstruction.
