An experimental model for lymphedema in rabbit ear.

Area of Science:

• Veterinary Medicine
• Surgical Research
• Pathology

Background:

• Lymphedema is a chronic condition characterized by fluid accumulation and tissue swelling.
• Existing experimental models for lymphedema may be complex or costly.
• Developing accessible models is crucial for advancing research into lymphedema pathogenesis and treatment.

Purpose of the Study:

• To describe a simple and inexpensive method for creating an experimental lymphedema model in rabbit ears.
• To validate the efficacy of the model through various measurement techniques.
• To utilize the model to explain clinical phenomena and suggest treatment modifications.

Main Methods:

• A surgical procedure was performed on rabbit ears to induce lymphedema.
• Lymphedema was assessed using measurements of ear thickness, water displacement, and skin thickness.
• Histopathological analysis and lymphatic diameter measurements were conducted on experimental ears.

Main Results:

• The experimental lymphedema model was successfully established in 47 out of 50 rabbit ears (94% success rate).
• Multiple assessment methods confirmed the presence of lymphedema.
• Three rabbit ears were excluded due to technical failures.

Conclusions:

• The described method provides a simple, inexpensive, and effective experimental model for lymphedema in rabbit ears.
• The model facilitates the study of lymphedema pathophysiology and clinical manifestations.
• Findings suggest potential modifications for microlymphaticovenous anastomosis procedures in lymphedema treatment.
