Functional and Anatomical results using Titanium Prostheses and Titanium Prostheses with Porous Hydroxyapatite in middle ear surgery

The objective of this investigation is to compare the anatomical and functional outcomes of middle ear ossicular chain reconstruction using two different prosthetic materials: conventional titanium prostheses and titanium prostheses coated with hydroxyapatite. This study employs a retrospective analysis of patient data.Modern otosurgical practice has embraced a single-stage approach that combines initial surgical interventions, such as scar removal, retraction pocket elimination, tympanic membrane defect repair, and sanitation, with middle ear ossicular chain reconstruction. However, achieving predictable success in restoring middle ear sound conduction remains challenging. A multitude of factors can influence surgical outcomes, including the underlying pathology, intraoperative findings, variations in surgical techniques, prosthesis design and mechanical properties, tympanic cavity ventilation methods, and the extent of scar management during both the early and late postoperative periods.
