OBJECTIVE To investigate the related parameters of the temporal bone structure for determining the position of implanting electrode into the scala tympani in cochlear implantation surgery through the facial recess and epitympanum approach. METHODS In a surgical simulation experiment, 20 human temporal bones were studied and measured to determine the related parameters of the temporal bone str...

OBJECTIVE To characterize preoperative and postoperative audiologic findings in patients with superior semicircular canal dehiscence syndrome. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS Patients with documented superior semicircular canal dehiscence syndrome (according to history, vestibular testing, and high-resolution computed tomography imaging) ...

Tympanomastoid surgery for cholesteatoma is a procedure designed to eliminate the disease and maintain a safe and dry ear. This retrospective study was designed to evaluate the functional results of cholesteatoma patients who underwent canal wall down mastoidectomy in conjunction with a tympanoplasty. Operated ears due to chronic otitis media with cholesteatoma were considered for the study. Th...

OBJECTIVE To describe the technique used for total ossiculoplasty with the Fisch titanium total prosthesis and evaluate the 1-year postoperative functional results in patients presenting with the stapes (or footplate) without the malleus handle. STUDY DESIGN Prospective trial with preoperative and postoperative comparison. SETTING Academic and private practice tertiary care center for otolo...

We report a rare case where Q-tip induced mixed hearing loss without perilymph fistula and demonstrate the need for computed tomography imaging with three-dimensional reconstruction where fracture and dislocation of the stapes are suspected. A 28-year-old male experienced an accidental penetrating injury by a Q-tip in the right ear 6 years previously. Temporal bone computed tomography revealed ...

The Vibrant Soundbridge (VSB) with stapes clip coupler placement at the stapes head has been used successfully to treat mixed hearing loss. Coupling between the floating mass transducer of the VSB and the stapes head is technically less demanding than incus vibroplasty and is more likely to generate a positive outcome without significantly changing residual hearing or resulting in medical or su...

The annular ligament provides a compliant connection of the stapes to the oval window. To estimate the stiffness characteristics of the annular ligament, human temporal bone measurements were conducted. A force was applied sequentially at several points on the stapes footplate leading to different patterns of displacement with different amounts of translational and rotational components. The sp...
