ABSTRACT Aim: A wide variety of materials are used as a partial ossicular replacement prosthesis in ossiculoplasty. Data on the use of the head of the malleus for partial ossicular reconstruction is quite limited in the literature. The main objective of our study is to compare the functional and anatomic outcomes of ossiculoplasty using an autograft head of the malleus and hydroxyapatite partial ossicular replacement prosthesis (HA-PORP) in Austin-Kartush type A ossicular chain defect.
