Abstract

Rhinosinusitis is a severe sickness and may have serious complications. Orbital complications happen more often, due to anatomical particularities and are lethal in 5% of patients. They vary from inflammatory signs to proptosis, loss of ocular motility and blindness.

AIM:

We propose a new classification of acute rhinosinusitis complications.

METHODS:

A review of 83 patients with CT scan and clinical reports. Patients were evaluated at HCFMRP-USP between 1995 and 2005 and were diagnosed with complicated rhinosinusitis.

RESULTS:

In sixty-six patients, were identified three types of orbital complications: orbital cellulitis (46.9%), subperiosteal abscess (40.9%) and orbital abscess (12.1%). Seventeen were considered as eyelid infections and excluded from this new classification system.

CONCLUSIONS:

The existing classifications of orbital complications, as Chandlers, do not consider the orbits anatomical characteristics and became obsolete after the development of the CT scan. This study proposes a new, more objective classification to guide the physician in establishing lines of conduct for each case.
