A study to evaluate bone and cartilage ossiculoplasty in patients of ossicular disruption due to chronic suppurative otitis media
Keywords:Chronic otitis media, Ossiculoplasty, Autologous incus, Pure tone audiometry
Background: Ossiculoplasty for ossicualar disruption in patients of chronic otitis media (COM) can be done by using either bone or cartilage. The present study was planned to compare bone and cartilage ossiculoplasty in patients of ossicular disruption due to COM.
Methods: The prospective observational study was carried out in patients, who were admitted in the department of otorhinolaryngology of a tertiary care teaching hospital of Rajasthan during two years from November 2017 to November 2019. All patients with ossicular disruption due to COM and conductive hearing loss more than 40db were included in the study. Patients with sensorineural hearing loss were excluded from the study. Pure tone audiometry (PTA) was done before surgery. Hearing improvement was assessed 3, 6 and 12 months after surgery.
Results: In the present study 20 patients underwent bone ossiculoplasty using autologous incus and autologous cartilage was used in 80 patients for ossiculoplasty. Post-operative hearing gain was significantly more in autologous incus patients (22.7±4.2 db) compared to autologous cartilage (19.5±3.4 db) (p=0.002).
Conclusions: The present study concluded that post-operative hearing gain was significantly better with autologous incus compared to autologous cartilage although both showed good results in terms of hearing gain.
