Management of the partial avulsions of the auricle
Review published in Laryngo Rhino Otol (2022)
Abstract
Injuries of the auricle can range from simple lacerations to complete avulsions. Many techniques of ear replantation have been described in the literature in addition to the type and extent of the involved auricular structures. A direct reattachment of the amputated pinna without microsurgery is rarely successful due to necrosis of the avulsed fragment. Whereas, reconstructions with pocket methods and their variations might lead to better results. In this article we would like to discuss some of these approaches and demonstrate a two-stage reconstruction technique for subtotal avulsion of the auricle. Ohrmuschelverletzungen zählen zu den selteneren Traumata im Kopf-Hals-Bereich. Aufgrund der komplexen Anatomie des Knorpels und der begrenzten Blutversorgung bedürfen sie einer raschen und strukturierten Behandlung. Für die Behandlung sowohl von leichten Verletzungen als auch von (sub-)totalen Abrissen der Ohrmuschel stehen unterschiedliche Therapieoptionen zur Verfügung. Eine direkte Readaptation einer (sub-)total abgerissenen Ohrmuschel ohne mikrovaskulare Anastomose ist aufgrund des hohen Risikos von Haut- und Knorpelnekrosen nur selten erfolgreich. Mehrzeitige Rekonstruktionen mit Pocket-Methoden sind dagegen gut etabliert. Die vorliegende Arbeit beschreibt einige dieser Ansätze und demonstriert eine 2-stufige OP-Technik eines Ohrmuschelteilabrisses aus dem eigenen Patientengut.

Summary
Review of partial auricle-avulsion management approaches including microsurgical replantation and salvage strategies.
Why This Matters for Hirudotherapy
This article discusses management approaches for partial and subtotal avulsions of the auricle (external ear), comparing direct reattachment, pocket methods, and staged reconstruction techniques. The authors present a two-stage reconstruction technique for subtotal auricular avulsion from their own patient population, noting that direct reattachment without microvascular anastomosis is rarely successful due to the high risk of skin and cartilage necrosis. The abstract contains no mention of leeches, hirudotherapy, hirudin, or any leech-derived therapeutic agent. Therefore, the article has no direct relevance to ASH's research domain of hirudotherapy or leech-based therapeutics.
