[Minimally invasive surgery of sinugenic orbital complications in childhood].

Orbital complications of acute sinusitis are classified into inflammatory edema, orbital cellulitis, subperiostal abscess and orbital abscess. The diagnosis is based on endoscopy of the nose, computed tomography of sinuses and orbit and an ophthalmological examination. Endonasal sinus surgery improves drainage and ventilation of sinuses and is free of long-term complications as observed with previous surgical techniques. Thus, the early surgical treatment of orbital complications is indicated even in children. Inflammatory edema and orbital cellulitis will still be treated conservatively. Subperiostal abscess and orbital abscess are treated surgically.
