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.
