Abstract

Facial trauma can pose challenging reconstructive obstacles in both maintaining tissue viability and restoring aesthetic appearance. Medicinal leech therapy can help to promote vascular decompression in the setting of venous congestion. A retrospective chart review was conducted to identify patients who underwent medicinal leech therapy following venous stasis secondary to repair of a complex facial laceration. Three patients were identified; 2 suffered auricular avulsion, while 1 suffered a lip avulsion. All patients suffered from venous congestion and underwent medicinal leech therapy for 48 to 72 hours with reduction of edema and stasis. Decompression was successfully achieved with no further sequelae on last follow-up. Medicinal leech therapy is an adequate treatment for venous congestion following traumatic soft-tissue repair of the face. The authors advocate for the utilization of medicinal leeches to combat venous congestion after repair, particularly when arterial inflow remains intact.

Summary

Facial trauma can pose challenging reconstructive obstacles in both maintaining tissue viability and restoring aesthetic appearance. Medicinal leech therapy can help to promote vascular decompression in the setting of venous congestion.

Why This Matters for Hirudotherapy

This retrospective chart review examined three patients who received medicinal leech therapy for venous congestion following repair of complex facial lacerations, including two auricular avulsions and one lip avulsion. All patients underwent 48–72 hours of leeching with observed reductions in edema and stasis, and decompression was achieved without reported sequelae at last follow-up. The study is directly relevant to hirudotherapy, providing clinical evidence for the use of medicinal leeches in managing venous congestion after traumatic soft-tissue repair of the face, particularly when arterial inflow remains intact. However, the findings are drawn from a very small number of patients and the retrospective design, limiting the strength and generalizability of the conclusions; no comparative or long-term outcome data are presented.
