Frontal bone defect with frontal sinus mucopyocele.

For this patient's treatment, all three consultants advise against the Lynch-type frontoethmoidectomy procedure, with or without mucoperiosteal flap reconstruction of the nasofrontal duct. Treatment plan: Culture and sensitivity of pus; 2-3 weeks of intravenous antibiotics followed by osteoplastic flap fat obliteration of frontal sinus; delayed defect repair with methyl methacrylate (Montgomery). Trephination followed by treatment with local and systemic antibiotics (Donald); removal of infected bone and soft tissue (sinus collapse) and delayed defect repair in 6-12 months (Donald, Calcaterra) with metylmethacrylate (Donald) or in situ cured silicone elastomer (Calcaterra).
