All ppts published in my name were presented or made by me during my PG at AFMC. I received lot of inputs, guidance & help from my faculty, colleagues, seniors and juniors as well as from the presentations made by them at ENT dept, AFMC. Without their help neither my knowledge, nor my presentations and nor me could have been complete. I thank them all for their contribution and their wishes in making this dream of an ENT website a reality.
