Comparison of Autologous Malleus Head and Hydroxyapatite Partial Replacement Prosthesis in Ossicular Chain Reconstruction
Journal Title: Yeni Yuzyil Journal of Medical Sciences - Year 2021, Vol 2, Issue 3
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 (HAPORP) in Austin-Kartush type A ossicular chain defect. Material and Methods: Patients who underwent surgery due to attic cholesteatoma and had Austin-Kartush type A ossicular chain defect (with intact and mobile stapes, no incus, or not used as an autograft in ossiculoplasty) were included in the study. The patients were divided into two groups according to the material used for ossiculoplasty: those with malleus head (Group I) and those with HA-PORP (Group II). The groups were compared in terms of hearing gains obtained from the results of pre-and post-operative hearing tests, prosthesis extrusion rates, and recurrent cholesteatoma development rates. Results: Postoperative air-bone gap (ABG) values were significantly lower in group I. Postoperative ABG gains were also significantly higher in group I. Functional success rates (postoperative ABG ≤20 dB) were higher in Group I (65%) than in Group II (50%), but the difference was not significant. Prosthesis extrusion rates were significantly higher in Group II; there were no differences between the groups in terms of recurrent cholesteatoma. Discussion and Conclusion: When the incus is not available for ossiculoplasty, the head of the malleus can be considered as the first choice because it is biocompatible, cost-free, and has low extrusion rates compared with HA-PORP.
