Intraoperative ossicular chain status in patients with chronic otits media

Chronic otitis media (COM) poses a significant global health burden, contributing to ear discharge and preventable hearing loss. This study aimed to evaluate the ossicular status in COM patients undergoing surgery and correlate the findings with preoperative otoscopic and audiogram assessments. The primary focus was to discern differences in ossicular involvement between squamous and mucosal diseases, shedding light on distinct pathologies crucial for tailoring surgical interventions.

A total of 98 patients with COM (26 squamous disease, 72 mucosal disease) were included in the study. Analysis revealed the incus as the most commonly eroded ossicle, observed in 25 of 26 patients with squamous disease and 19 of 72 patients with mucosal disease. Conversely, the stapes exhibited remarkable resistance to erosion, remaining intact in 89 patients, with the stapes footplate found intact in all cases. Malleus erosion was observed in 13 patients categorized as “unsafe” and 6 patients in the “safe” category. Additionally, ossicular joints were more frequently eroded in squamous disease patients compared to those with mucosal disease. The study provides valuable insights into the distinct pathology of COM squamosal and COM mucosal cases, emphasizing the need for tailored surgical interventions to address the specific requirements of each patient group.

By correlating operative findings with clinical findings, this research contributes to a deeper understanding of COM pathology, paving the way for more targeted and effective intraoperative ossicular reconstruction strategies.
