Intraoral Hirudotherapy for Venous Congestion following Free Flap Head and Neck Reconstruction: Novel Intraoral Technique
Cohort study published in ORL; journal for oto-rhino-laryngology and its related specialties (2022)
Abstract
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.

Summary
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.
Why This Matters for Hirudotherapy
This report describes a novel technique for administering intraoral hirudotherapy to manage venous congestion following head and neck free flap reconstruction, in which a leech is sutured inside a clear cup or plastic lid and then applied to the compromised flap. This work is directly relevant to hirudotherapy practice, as it addresses well-recognized barriers to intraoral leech use—including risks of airway migration, infection from repeated manipulation, and application difficulty for less experienced staff—by proposing a standardized, pre-assembled device-based approach. For ASH's domain, the study illustrates practical engineering and workflow solutions that may improve the safety profile and clinical adoption of leech therapy in complex reconstructive settings. However, the abstract presents only a technical description without quantitative outcome data, patient results, or comparative analysis, and the authors themselves note that prospective studies are warranted to assess efficacy, so the clinical benefit of this technique remains undemonstrated.
