Mean age was 17.1\u2009\u00b1\u200916.7\u00a0years (range 13-days to 53-years), of which one was 13 days old, and all were immunocompetent. Eight (88.9%) patients had paranasal sinus disease, and seven (77.8%) had a subperiosteal abscess. Four (44.4%) had intracranial extension, including one (11.1%) case which was also complicated by superior sagittal sinus thrombosis. Empirical antibiotics, such as intravenous (IV) cefotaxime alone or IV ceftriaxone and flucloxacillin, were commenced. Following identification of nmMRSA, targeted therapy consisting of vancomycin and\/or clindamycin was added. Nine (100%) patients underwent surgical intervention. Average hospital admission was 13.7\u2009\u00b1\u20096.9\u00a0days (range 3\u201325\u00a0days), with two patients requiring intensive care unit (ICU) admission due to complications related to their orbital infection. All patients had favourable prognosis, with preserved visual acuity and extraocular movements, following an average follow-up period of 4.6\u00a0months (range 2\u20139\u00a0months).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>NMMRSA OC can follow an aggressive clinical course causing severe orbital and intracranial complications across a wide demographic.
