Endoscopic Optical Coherence Tomography for Evaluation of Success of Tympanoplasty
Objective: After tympanoplasty , it is often challenging to differentiate between different causes of a remaining air bone gap (ABG). Optical coherence tomography (OCT) offers a new approach for combined morphologic and functional measurements of the tympanic membrane and adjacent parts of the middle ear. Thus, it provides valuable diagnostic information in patients with a reduced sound transfer after middle ear surgery. Patient and intervention: A patient with history of tympanoplasty and a persistent ABG was investigated with endoscopic OCT before revision surgery. Main Outcome Measures: The oscillation behavior and the thickness of the reconstructed tympanic membrane was determined. The oscillation ...
