Aim To determine the hearing status in post canal wall down mastoidectomies and comparison in hearing outcome following use of PORPs, TORPs and cartilage grafts, or a combination of all.

Objectives To measure the pure tone average values of patients’ preoperatively and postoperatively and assess the improvement or decrement. To evaluate the efficacy of various materials used for reconstruction.

Materials and Methods Patients with chronic suppurative otitis media, atticoantral type in a tertiary institute between January 2013 and January 2018, who underwent canal wall down mastoidectomy with tympanoplasty. The study involved comparison of the pure tone audiogram values done as per standard care of treatment of patients who underwent canal wall down mastoidectomy. The efficacy of reconstruction material used was based on the hearing outcomes of the patient. Results were analyzed using appropriate statistical methods. Outcome measured based on the improvement or worsening of hearing parameters following surgery as per the audiogram values.

Result Hearing improvement was noted in significant percentage following canal wall down mastoidectomy. Further details shall be discussed during the presentation.
