Middle ear status at NPC diagnosis
At the time of NPC diagnosis 14 patients (19.2%) presented with middle ear effusion. When comparing the T stage at presentation, 85.7% of patients who presented with effusion were with an advanced T stage (stages 3,4) compared to only 60.4% in the non-effusion group (P value of 0.07). Following radiotherapy, 7 patients had a resolution of their MEE. Analysis of histopathological factors between patients with MEE at presentation and those without found no difference in EBV status or Ki-67 between groups.
