Background: In a condition with absence of autologous material or in functional failure, ossicular prosthesis was subsequently developed. The role of this prosthesis is to transmit the sound waves from the tympanic membrane to the stapes head, either directly, or indirectly. In spite of the presence of various types of materials (titanium, gold, hydroxyapatite, steel, ceramics, Teflon etc.), titanium and hydroxyapatite (HAP) prostheses are the most commonly used materials in ossiculoplasty. Aim of work: To assess the cartilage as sound transmitter in ossiculoplasty by using two different techniques. Methods: A randomized controlled trial was carried out on 18 patients at ENT Department, Zagazig University Hospitals, from Aug. 2018 to Aug. 2019 suffering from chronic suppurative otitis media with ossicular discontinuity “erosion" with or without cholesteatoma and presented by otorrhoea and hearing loss. There were randomly divided into 2 groups with nine patients in each group. Group (A) included patients who undergo the Single Cartilage Block Ossiculoplasty and Group (B) included the patients underwent the Double Cartilage Block Ossiculoplasty. Results: There is statistically significant difference between the studied groups regarding Hearing outcome. Eight cases (88.9%) out of nine with SCB group versus only three out of eight cases (37.5%) with DCB shows successful outcome with ABG
