Audiological Aspects
Effective against head shadow
1. "Speech audiometry showed a significant head shadow benefit with both implantable bone conduction devices." (Desmet et al. 2012)

Audiological Aspects
Better speech understanding
1. "Bone-anchored hearing aid systems transmit sound to the better side by bone conduction (BC). (...) Several studies have shown significant speech understanding improvement and improvement of quality of life for SSD." (Laske et al. 2015)
2. "Mean speech recognition scores in noise improved significantly under various signal-to-noise ratio (SNR) for both groups." (Oh
et al. 2020)

Audiological Aspects
Better Word Recognition Score
1. "The median WRS at 65 dB SPL increased significantly from 0 to 80% (mean: 8% versus 84%)." (Salcher et al. 2017)
2. "WRS in quiet improved significantly on average by 70% in SSD and 53% in MCHL relative to the unaided condition (p < 0.01)".

Audiological Aspects
Subjective benefit
1. "Both patients with MCHL and patients with SSD had subjective satisfaction and improved quality of life with [Bonebridge]." (Oh et al.2019)
2. "Bone-anchored hearing aid systems transmit sound to the better side by bone conduction (BC). (...) Several studies have shown significant speech understanding improvement and improvement of quality of life for SSD." (Laske et al. 2015)
3. "Nearly all patients experienced a subjective benefit in all hearing situations assessed with the BBSS (9/10). There was a significant improvement in the categories speech in quiet, distant speaker, reverberant room, and overall." (Salcher et al. 2017)

Patient-reported Aspects
No need to close the good ear / good ear stays free
1. "A CROS conducts signals from the hearing field of the poor ear via a wire (or FM/Bluetooth) to a microphone in the ear canal of the better ear. (...) A [bone conduction device] transfers signals from the hearing field of the poor side to the better hearing ear by vibration of the bone of the skull." (Peters et al. 2014)

Patient-reported Aspects
Easy pre-OP testing
1. "A trial with a bone conduction device] can be performed by attaching the [bone conduction device to a tight headband."

Patient-reported Aspects
Improvement of scholastic performance
1. In children, a fairly rapid hearing rehabilitation period is important since they may, after a fairly short time, lag behind in school or in development since they frequently cannot follow classroom activities or social interactions (conclusion / Tomlinet al. 2014)
