Surgical removement of a Sialolith in a 25-year-old trotter gelding – a case report

Abstract

ZusammenfassungIn dem vorliegenden Fallbericht wurde ein 25-jähriger Traberwallach mit dem Vorbericht "Wickelkauen" für eine Zahnuntersuchung vorgestellt. Bei der Untersuchung fand sich eine faustdicke, harte und verschiebliche Umfangsvermehrung der rechten Backe des Pferdes, die sich in einem Zeitraum von neun Jahren herangebildet hatte. Am sedierten, stehenden Pferd wurden nacheinander die notwendigen oralen Zahnbehandlungen und die Exstirpation der Umfangsvermehrung über einen transkutanen Zugang durchgeführt. Die weiteren Untersuchungen ergaben, dass es sich um einen Siaolithen aus Kalziumoxalat handelte, der zentral ein Stück Stroh aufwies. Drei Wochen spä-ter zeigte das Pferd ein deutlich verbessertes Allgemeinbefinden.Schlüsselwörter: Pferd, Speichelstein, Chirurgie, Maulhöhle, transkutaner Zugang Surgical removement of a Sialolith in a 25-year-old trotter gelding, a case report This is a case report about a 25-year-old trotter gelding with a history of dysmastication. The horse was presented for a dental examination. A mass at the right cheek was observed for 9 years. A mass with a size of 10.0 x 5.0 x 4.0 cm that was palpable under the skin overlying the right maxilla in the region of the 3rd cheek tooth. The mass was noted to be firm, freely moveable, and nonpainful on palpation. At the oral examination a marked wave mouth, moderate dental exsuperantias and mild dental calculus was detected. A primary dental treatment was resolved. Surgical removal of the mass was performed by a transcutaneous approach in standing sedated horse, under local anaesthesia. Further investigations revealed a sialolith with a chemical composition of calcium and oxalate. When the sialolith was sawed in half, a small piece of straw was discovered in its center, around which concentric layers of mineral appeared to have been laid down. The horse was discharged from the hospital five days after surgery. The owner was advised to continue flushing the wound with 200 ml of a 0.1% chlorhexidine solution for another 8 days. Three weeks later the quality of life was much better than before and the wound healing was inconspicuous.
