Table 1. This table shows the operative findings and
pre-operative audiological results in both TEES and microsurgery groups.
There was no difference in pre-operative hearing levels between groups,
cholesteatoma was more extensive in the microscopic group.Table 2. This shows the types of ossiculoplasty reconstruction,
materials used in ossiculoplasty and the tympanic membrane graft.
Cartilage was the commonest material used followed by incus and titanium
PORP / TORP and there was no difference between groups. There was a
significant difference in the tympanic membrane graft material, with
more cases in the microscopic group using temporalis facia
(p<0.001)Table 3. This shows the outcomes at 3 and12 months following
surgery. There was no significant difference in hearing or other
outcomes apart from a higher incidence of myringitis in the TEES group
at 3 months (p=0.042). At 12 months following surgery, there was a
significantly lower AC level in the TEES group (p=0.033). All the other
outcomes did not show any significant difference.Table 4. This shows the mean differences of AC, BC and ABG
between those with and without erosion of stapes superstructure. There
was no statistically significant difference between groups.
