Abscessation following intralesional formalin treatment of congenital parotid salivary duct atresia

Abstract

SummaryA 5‐month‐old colt with a history of nonpainful left‐sided facial swelling present since birth was presented for evaluation and treatment. A diagnosis of congenital parotid salivary duct atresia was made, and surgical correction was attempted but was unsuccessful. Follow‐up treatments consisted of repeat intralesional injection of 10% neutral‐buffered formalin. The horse developed ventral mandibular abscessation with multiple draining tracts secondary to this treatment; however, no other significant complications occurred and a cosmetic outcome was achieved.
