Abstract
Orbital complications from sinusitis are briefly reviewed. Acute orbit is suggested as the common term for all stages in the development. Four patients with acute orbit and ethmoiditis are presented. All had transnasal ethmoidectomy and drainage of the orbit performed by functional endoscopic sinus surgery (FES). Surgical indications are discussed based on clinical signs and CT examination. The operation can easily be staged according to the needs of the individual patient, starting with drainage of the primary cause, the sinusitis. Orbital skin incisions are avoided. Postoperative regression of clinical symptoms has been rapid.
