Frontal sinus mucocele development in an adult patient with Apert syndrome

Frontal sinus mucoceles may present many years after traumatic injuries or surgical procedures involving the frontal bone, but have been rarely reported after fronto-orbital advancement. We describe a case of frontal sinus mucocele development in a 43-year-old patient with Apert syndrome who underwent fronto-orbital advancement as a child. This was treated with resection and free fibula osteomuscular flap reconstruction. Computer-aided design and manufacturing techniques were used to virtually plan the procedure and guide the osteotomies intraoperatively. Follow-up at 1 year postoperatively revealed no evidence of recurrence.
