Penetrating lingual foreign bodies in three horses.

Three horses examined for complaints of ptyalism and dysphagia were found to have metallic lingual foreign bodies. Metallic foreign bodies were located by oral examination combined with radiography. In 1 horse clinical signs resolved without removal of the foreign body. The foreign body was extracted via an oral approach in the second horse; a mandibular symphysiotomy and radiographic guidance were necessary for removal in the third horse. In all 3 cases, the presenting clinical signs subsided.
