Underlay tympanoplasty with anterior and posterior flaps for subtotal perforations.

In conventional underlay tympanoplasty, post meatal flap is elevated and graft placed medial to the handle of maleus. Out of this present series of 200 ears, in 90 cases posterior flap technique and in 110 cases both posterior and anterior flap was applied and results are studied after median observation time of 20 months. The success rate with combined anterior/posterior flap is better compared to the posterior flap alone. Different techniques described by various authors for tympanoplasty are also discussed in this paper.
