(¡¡¡) 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)
