Surgical Data
The median time from onset of fever (29 patients, 85%) to first surgical intervention was 4 days (range, 1-10 days). The average number of ESS per-patient was 3.2 (range, 1-11 surgeries per-patient). Twenty-four children (71%) required multiple procedures to control the disease. The nasal structures that were most involved in AIFR included the middle turbinates (n=16, 47%), nasal septum (n=13, 38%) and inferior turbinates (n=10, 29%). Eleven patients (33%) were diagnosed with extrasinus involvement, including the palate (n=5, 15%), the orbit (n=4, 12%) and the skull base (n=3, 9%). Involvement of the pterygopalatine fossa, nasopharynx or clivus was documented in 4 cases (12%). Major surgical complications included one case of significant intraoperative bleeding which was successfully treated surgically, along with blood transfusions, anterior and posterior packing and 24-hour observation in the intensive care unit.
