Also known as: Nasenscheuern
Die rostrale Abschürfung ist eine chronische Verletzung an Schnauze und Nase durch wiederholtes Scheuern oder Drücken gegen Terrarienwände, Glas oder Gitter. Sie ist meist eine Verhaltensreaktion auf Stress, mangelhafte Terrariengestaltung, einen Fluchtversuch oder das Bemühen, Partner oder Futter außerhalb einer Barriere zu erreichen. Anhaltendes Scheuern trägt Haut und Schuppen ab und legt rohes Gewebe oder Knochen frei, das sich leicht infiziert. Es ist ein häufiges, haltungsbedingtes Problem bei Landschildkröten sowie aktiven Echsen und Schlangen.
Rostral abrasion is wear and injury to the nose and snout caused by an animal repeatedly rubbing or pushing against the boundaries of its enclosure. It reflects an underlying behavioral or housing problem rather than a primary disease and is common in tortoises and active lizards and snakes.
Common triggers include enclosures that are too small or barren, transparent walls the animal repeatedly tries to walk through, persistent escape attempts, boredom, and stress from being unable to reach mates, food, or a basking site beyond a barrier.
Signs are reddened, raw, or scabbed areas on the snout and upper lip, loss of scales, swelling, and, in chronic cases, exposed bone, deformity, and secondary bacterial infection. The animal is often observed pacing and rubbing its nose against the enclosure boundary.
Diagnosis is based on the characteristic snout lesions together with observation of the rubbing behavior and a review of the enclosure design, size, and overall husbandry.
Treatment involves cleaning the wounds, applying topical and sometimes systemic antibiotics for infection, providing pain relief, and, most importantly, modifying the enclosure to stop the behavior. Adding visual barriers, opaque walls, more space, and enrichment addresses the root cause.
Prevent rostral abrasion with appropriately sized, enriched enclosures, opaque or visually broken-up walls, correct temperatures and hides, and measures to reduce stress.
