Intra-ductal Foreign Body (Fish Bone Fragment) as a Cause of Obstructive Sialadenitis: A Case Report.

Submandibular sialadenitis is a common ailment in otorhinolaryngological and oral surgical practice. Some of the common causes of sialadenitis include sialolithiasis, inspissated mucous plugs, strictures and anatomical ductal variations. Very rarely do foreign bodies cause obstructive sialadenitis. Fish bone as a foreign body is routinely seen, with the most common locations being oropharynx, hypopharynx, oseophagus and tongue. We report an intriguing case of a 40 year old male with sialadenitis of the right submandibular gland due to an intra-ductal fish bone.
