Objective: Orbital involvement is the most common complication of sinus infections. The epidemiology of the disease is continuously changing in the antibiotic era.
Materials and methods: Data on patients who were hospitalized due to acute sinusitis and orbital complications were retrospectively collected and analyzed from four medical centers in Israel during the years 2002-2012.
Results: 288 patients were included in the study, the average age was 14.4 years, 180 were males, and 220 were children. No significant annual increase in the number of patients was noted. The lowest number of patients was found during the summer 19.4%. A linear direct correlation was found between older age and prolonged hospital stay. Children were presented with a significantly higher Chandler score than adults. No patient had cavernous sinus thrombosis. 101 (35%) patients received antibiotics before hospital admission. Their average hospital stay was similar to those who were not treated prior to admission. 106 patients (39.8%) had fever. A direct correlation was found between older age and the presence of fever. 102 (35.4%) patients had leukocytosis. The difference in white blood cell count between patients younger than two years of age to the other groups was statistically significant. Forty four (15.3%) patients underwent surgical intervention. A direct correlation was found between leukocytosis and older age to surgery.
Conclusions: Periorbital cellulitis occurs mainly in children and males and is less frequent in the summer. Children tend to have worse orbital involvement with lower temperatures than adults. Older age and leukocytosis are associated with surgical intervention.
