Intraoral Hirudotherapy for Venous Congestion following Free Flap Head and Neck Reconstruction: Novel Intraoral Technique

Intraoral hirudotherapy is traditionally used for venous congestion following head and neck free flap reconstruction. Many institutions and healthcare teams have been reluctant to use intraoral leech therapy due to risks such as migration into the airway, increased infection from intraoral manipulation, and patient discomfort. Several protocols recommend blocking the path to the oropharynx via gauze or leaving a tracheotomy in place to protect the airway. This report pre-sents a novel technique for intraoral hirudotherapy that is safe and simple for treatment of free flap venous congestion. The base of a clear cup or a plastic lid is utilized, and the leech is attached onto the inside of the lid with 2 sutures near each end. Several cups with leeches attached are made at a time to reduce delay and difficulty of application by less experienced clinical staff. The leech is then applied onto the compromised flap and then simply removed once it has unlatched from the flap. This method allows the leech to be applied with ease by multiple members of the healthcare team, decreases the need for intraoral manipulation, and reduces the risk of migration into the aerodigestive tract. Future prospective studies are warranted to assess the efficacy of this technique.
