All 11 studies were observational. In most studies, comparisons between unilateral and bilateral BAHA were intra\u2010subject. Bilateral BAHA provided audiologic benefit compared to unilateral BAHA (improved thresholds for tones [2 studies], speech in quiet [5 studies] and in noise [3 studies], and improved localization\/lateralization [3 studies]) and patients\u2019 perceived subjective benefit from bilateral BAHA (3 studies).
