Effects of Stimulation Rate With the FS4 and HDCIS Coding Strategies in Cochlear Implant Recipients.

Objective: The aim of the present study was to evaluate the effect of stimulation rate on speech perception and sound quality for the fine structure strategy FS4 and the envelope-based strategy high definition continuous interleaved sampling (HDCIS).

Study Design: Randomized crossover trial with four conditions.

Setting: Tertiary referral.

Indication criteria and outcomes with the Bonebridge transcutaneous bone-conduction implant.

Objectives/hypothesis: The aim of this study was to evaluate functional hearing gain, speech understanding, and preoperative bone-conduction thresholds with the bone-conduction implant Bonebridge.

Study Design: Retrospective study at a tertiary referral center.

Methods: Twenty-four consecutive Bonebridge patients were identified.

Vibroplasty in mixed and conductive hearing loss: comparison of different coupling methods.

Objectives/hypothesis: To evaluate modified coupling techniques of the Vibrant Soundbridge system in patients with mixed and conductive hearing loss and to compare it with conventional vibroplasty.

Study Design: Retrospective study.

Methods: Two different groups were evaluated: 1) nine cases of conventional incus vibroplasty in comparison with 2) nine patients with modified coupling of the floating mass transducer.
