Post-operative local complications
There was no significant difference in post-operative complications
between the IOH and NIOH groups. Specifically, post-operative
inflammatory complications were observed in two patients of the IOH
group (one with local swelling and one with acute otitis media) and in
28 patients of the NIOH group (14.3%; thirteen with swelling, eight
with otitis media, four with local infection, two with meningitis, and
one with otitis externa). According to multivariate analysis, IOH is not
associated with post-operative complications (p = 0.89, Table
3 ).
