Participant characteristics
Between 2010 to 2022 there were 40 cases of inverted papilloma - 22 were primary and 18 were secondary. A consultant rhinologist did primary cases, whereas secondary cases were operated on by a general ENT surgeon at the first procedure. Our cohort included 26 males and 14 females. The average age at surgery was 62.8 ranging from 22.4 to 89. In addition to the endoscopic approach, 31% of our participants had a medial maxillectomy or Draf IIb/III as an adjunct.
