INFLAMMATORY DISORDERS Sialadenitis which may be acute, chronic or acute on chronic, caused by either bacteria or virus.
CHRONIC SUBMANDIBULAR SIALADENITIS: This is caused by a stone formation in the duct. There is acute painful swelling, precipitated by eating and resolves spontaneously in 1-2 hrs after meals. On examination the gland is enlarged, firm and tender. Pus may be seen coming out of the duct.
Management : if the stone is in part of the duct anterior to the point where it is crossing the lingual nerve, remove it by a direct incision over the stone and do not stitch the wound in the duct. if the stone is in the posterior part, excise the whole gland and ligate the duct.
