Orbital complications of pediatric sinusitis: treatment of periorbital abscess.

Twenty-six children requiring surgical intervention for orbital complications of acute sinusitis were treated at our institutions between 1985 and 1995. Twenty patients were successfully treated surgically utilizing endoscopic/microscopic endonasal surgery, or traditional external ethmoidectomy. However, six patients failed to respond to initial surgical attempts and ultimately required a revision. In one of these six patients the development of an intracranial abscess also necessitated a craniotomy for surgical drainage. Analysis of these six failures was performed with special attention given to the reasons for initial surgical failure and possible means for preventing revision surgeries.
