Review articleOpen access

AbstractThe aim of this audit was to assess the effectiveness of botulinum toxin B (NeuroBloc®, Eisai Ltd.) in the treatment of drooling. Over a period of 18 months patients treated with NeuroBloc® botulinum toxin (BTX) for serious drooling (drooling score more than 7) were invited to complete a questionnaire on their experience of drooling and the impact of treatment. A total of 170 questionnaires were given to consecutive patients or carers and 145 (85%) responded. Of these, 128 (88%) reported that symptoms had improved by 6/10 or more on a visual analogue scale (VAS), and 54 (37%) reported compete resolution of drooling (10/10 VAS). A total of 139 (96%) would recommend the treatment to others.
