case_images: Pure tone audiometry proved a moderate conductive hearing loss in the right ear, with a 4-frequency (500, 1000, 2000, and 4000 Hz) mean of 33 dB, and borderline normal thresholds in the left ear (Figure 1).
case_images: Intraoperative view of the middle ear (photo and diagram). After performing tympanotomy a disconnection between stapes superstructure and incus with a normal stapes footplate is observed. I: long process of the incus; H: head of the stapes; C: stapes crura; F: stapes footplate; T: tympanomeatal flap; M: mucosal folds.
