Cmpica-tins f mid ead trauma are unusua, but in rare cases it can be ife-treatening and require neursurgica interventin (0.4%–1.0%).

Te reprts f sku radigraps r CCT scans were pr-vided by neurgists, neursurgens r radigists. Data analyses Statistica anaysis was dne by using SSPS 12.0 fr Windows (Statically Package for Social Sciences) . Categrica data were an-ayzed by using χ 2  anaysis. reSultS A tta f 2600 patients aged frm 0 t 19 years wit a istry f ead trauma presented t te Emergency De-partment in te study perid; 1888 (72.6%) ad mid ead trauma. Regarding GCS cassicatin, 1.9% f patients ad a GCS 13, 4.4% ad a GCS 14 and 93.7% ad a GCS 15 n admis-sin.

We b-served tat 437 (23.1%) patients ad ess tan 2 years f age.Patients wit mid ead trauma were submitted t 978 sku radigraps studies (a tta f 1956, incuding ater-a and frnta views) and 734 CCT scans. We registered abnrma sku radigraps in 2.5% f tese patients and simpe inear sku fracture was te mst frequent nding (2.1%). In reference t cidren ess tan 2 years f age (437 patients), ny 11 (2.5%) ad fractures n sku radigraps. Amng tese eeven patients, 09 were victims f fa frm a eigt and tw suffered mutipe trauma and were sub-mitted t a CCT scan. ony tw patients ess tan 2 years-d underwent a neursurgica prcedure and tey were victims f isated ead trauma. Cnsidering CCT scan as te gd-standard imaging study in mid ead trauma victims, sku radigraps ad a sensitivity f 60% (Tabe 1).Reviewing 734 CCT scans, abut 10.9% ad abnrma-ities and te main findings were fractures (6.2%), brain sweing (3.3%) and extradura ematmas (2.0%) (Tabe 2). Amng tse patients w ad abnrma ndings n CCT scans, 40.5% ad a istry f fa frm a eigt, 37.1% were victims f trafc accidents and 6.3% ad a grund-eve fa istry. ony 48 (2.5%) f a patients underwent a neursurgica prcedure.Cncerning GCS cassificatin, 44.4% f patients wit GCS 13 ad abnrma ndings n CCT scan ( χ 2 =12.2, ρ =0.01); amng tse wit GCS 14, 55.4% ad atered CCT scan ( χ 2 =48.9, ρ =0.01), and ny 8.1% f patients wit GCS 15 ad abnrma CCT scan. We as evauated if mutipe trauma was assciated wit a iger frequency f abnrma CCT scans. Amng patients wit isated mid ead trauma, 8.8% ad abnr-ma ndings n CCT scans, against 16% f patients wit mutipe trauma ( χ 2 =13.4; ρ =0.05). one patient wit mid ead trauma died during te study.

Te iger incidence f abnrma CCT scans in mu-tipe trauma patients is prbaby due t mre severe mecanisms f injury invved in tese accidents wen cmpared t isated ead trauma nes.
