Unlabelled:
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.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
