Table 2 A comparison between the scalar location in both the posterior tympanotomy and the EAEA groups; 69% of the ST location was via the EAEA which represented 100% of the endoscopic cases in comparison to only 31% via the conventional approach which was only 45% of the conventional cases, a difference that was found statistically significant (p < 0.001*)
