National survey of the use and application of leeches in oral and maxillofacial surgery in the United Kingdom

Abstract 

We investigated the use of leeches by oral and maxillofacial surgeons to establish whether they are used according to a standard protocol, and to ascertain whether clinicians Knew which leeches they are using and from where they are sourced. A self-designed questionnaire sent to 154 oral and maxillofacial surgery units in the United Kingdom included questions about the use of leeches, whether a protocol was followed, the number and type used, and their source. Of the 74 (48%) returned, 13 units (18%) used leeches, most commonly for the salvage of free flaps (n=7). Twelve units had no protocol for their application, and five respondents were either incorrect or did not know the type of leech that was used. The study shows that further education and support may be necessary in the application of leeches within the speciality, and that a protocol is needed for their use.
