Özet
Objective: This study aimed to investigate the relationship between air-bone gap (ABG) and wideband absorbance (WBA) values in patients with conductive hearing loss resulting from four middle ear pathologies: Tympanic membrane perforation, middle ear effusion, ossicular chain discontinuity, and otosclerosis. Methods: Air and bone conduction thresholds and WBA values were measured at 0.25, 0.5, 1, 2, and 4 kHz under ambient pressure. Correlations between ABG and WBA were analyzed in each pathology group to explore diagnostic relevance. Results: Significant correlations were identified for specific frequencies and pathologies. In the middle ear effusion group, ABG was negatively correlated with WBA at 0.25 kHz in the right ears (r=-0.570, p=0.022), whereas a positive correlation was observed in the otosclerosis group at the same frequency (r=0.570, p=0.048). Additionally, a negative correlation was noted at 4 kHz for the left ears across all groups (r= -0.270, p= 0.034). Conclusion: Preoperative WBA measurements provide valuable insights into middle ear function, offering diagnostic and surgical planning advantages for patients with conductive hearing loss. These findings suggest incorporating frequency-specific WBA evaluations into clinical practice can enhance the precision of middle ear pathology assessments.
