Objectives/Hypothesis: The purpose of the present study was to show our preliminary results regarding the endoscopic ear surgery application in malleostapedotomy surgery. Study Design: Case series. Methods: Six patients (four females and two males) who underwent endoscopic ear surgery as revision surgery for otosclerosis were enrolled in this study. For endoscopic malleostapedotomy surgery, rigid angled endoscopes at 0 ° and 30 ° with a length of 14 cm and an outer diameter of 3 and 4 mm were used.

Objectives/Hypothesis: To evaluate the influence of the diameter of stapes prosthesis on functional outcomes in stapes surgery. Study Design: Prospective cohort study. Methods: Fifty consecutive small fenestra stapedotomies performed using a 0.4-mm-diameter prosthesis were compared with 50 consecutive small fenestra stapedotomies carried out using a 0.6-mm-diameter piston. Audiological assessment following the recommendations of the Committee on Hearing and Equilibrium was performed 1 month after surgery. Postoperative complications between the two groups were noted.

Objective

To evaluate the feasibility and efficacy of a new high-resolution 3D endoscope in endoscopic ear and lateral skull base surgery.
Methods

We present a case of a 50-year patient with a severe form of otosclerosis (double ring) that was successfully implanted. We used a bone-anchored hearing implant for restoring the hearing in the right side and a cochlear implant in the left side; both surgeries did not show any complications. For reducing the risk of a secondary bone ossification related to the trauma of cochleostomy for electrode's insertion, we used a round window approach. The patient recovered a normal auditory threshold and normal speech perception capacity both in silence and noise conditions 1 year after surgery.
