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).
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.
