Comparison of two different bone anchored hearing instruments: Baha-5 vs Ponto-plus

BACKGROUND: 5 (Cochlear Bone Anchored Solutions AG, Mölnlycke, Sweden) available in the literature. AIMS/OBJECTIVES: The primary aim was to compare the performance of the Baha 5 with the Ponto Plus device in terms of speech understanding in quiet and in noise. In addition, to determine statistically whether or not the difference between the abutment systems created any variation in terms of skin reaction. MATERIALS AND METHODS: Twenty bone-anchored hearing instrument users, ten in each group, were evaluated for speech understanding in quiet and several signal-to-noise ratios using the Turkish Matrix Test in a two-speaker setup. The Holger classifications were also reviewed to determine adverse skin reactions. RESULTS: It was revealed that the hearing results of both devices were similar and, when the skin reactions were compared, there was no statistically significant difference between the two-implant systems. CONCLUSIONS AND SIGNIFICANCE: Because of the similar results of the groups, it can be interpreted as the key different device features such as the size, weight, colour alternatives, and the ease of use of the devices might be important in terms of device preference.
