It includes 104 patients, Group-A 59 patients (Underlay technique) and Group-B 45 patients (Over-underlay technique).
Result: Graft success rate overall 84.62%, Group-A- 84.75% (Medial to malleus) and Group-B- 84.44% (lateral to malleus). Pre- and post- operative air- bone gap of two groups were compared.
