RESULTS: Fifty-one patients (35 male) with a mean age of 6.1 years were identified. Main clinical signs included fever (mean 38.5°C), proptosis (82.3%), extraocular motility restriction (74.5%), and ocular pain (41.1%). Forty-one patients were successfully treated with antibiotics and 10 required endoscopic sinus surgery. On between-group comparison, the surgery group had severe eye pain (p = 0.009), severe proptosis (P = 0.02), longer intravenous antibiotic treatment (13.2 vs. 9.2 days, p = 0.04), and several imaging findings. Additional factors associated with surgical intervention included older children, subperiorbital abscess, larger dimension of the abscess (mean 15 mm), involvement of frontal sinuses and findings of intraorbital air bubbles. There was no visual deterioration in either group and no late sequelae.
OBJECTIVE: The purpose of this study was to identify features of orbital cellulitis that predict response to conservative treatment without surgical intervention and factors associated with a decision for surgery.
PATIENTS AND METHODS: The medical files of patients diagnosed with orbital cellulitis at a tertiary medical center in central Israel between 1995 and 2010 were reviewed for clinical data, diagnosis, complications, and type of treatment. Comparison was made between patients treated with antibiotics and patients treated with antibiotics and surgery.
CONCLUSION: Factors associated with surgery included age older than 9 years, severe ocular pain, severe proptosis, and subperiorbital large abscess. These may be used for early identification of patients at risk of failure of only medical management.
