Abstract

Background and Aim: Standard TYMPANOMETRY provides a valuable tool for evaluating middle ear abnormalities although it often fails to distinguish different pathologies that effect the ossicular chain. Multi-frequency TYMPANOMETRY (MFT) has made it possible. The aim of the present study was to evaluate the role of MFT for distinguishing chronic middle ear pathologies.Materials and Methods: This cross-sectional study was conducted on 60 patients. One ear was selected from each patient (60 ears) and were classified into 4 groups according to the type of their middle ear pathology adhesive otitis media; middle ear effusion; atelectasis and retraction pocket. The following parameters were elicited from MFT: static admittance, resonant frequency, and phase angle. The clinical results were compared with the operative findings.Results: There is significant difference between resonant frequency and phase angle of 4 groups. No statistical correlation exists between phase angle and resonant frequency. The operative results of MFT are correlated with the operative findings.Conclusion: The most significant parameter derived from MFT to distinguish between the 4 groups seems to be the resonant frequency.
