(¡¡¡) Peak Middle Ear Pressure
Out of 50 ears in conventional curettage group, 38 ears (76%) had
impaired peak middle ear pressure at presentation while in endoscopic
microdebrider assisted group, 36 ears (72%) had abnormal pressure.
Comparison showed a p value of 0.650 which shows that there was no
significant difference in the groups. At first follow up, 15 ears (30%)
in conventional curettage group and 7 ears in endoscopic microdebrider
assisted group had abnormal peak middle ear pressure (p value 0.045 =
significant). After 2nd follow up, 6 ears (12%) in
conventional curettage group and 4 ears (8%) in endoscopic
microdebrider assisted group had abnormal peak pressures (p value 0.507
= not significant). (Table 3)
