Foreign Body Induced Sialolithiasis Treated by Sialoendoscopic Intervention

Abstract

This study supported the possibility that some sialoliths resulted from a retrograde migration within the salivary ducts. In our study, the occupations (fisherman), the diet habit (seafood), and the injury history (a remembered incident of implanted fish bone and the following symptoms) were obviously related to the stone formation that was induced by the fish bone.

Obstructive Sialadenitis of Submandibular Gland Due to a Nail-like Fish Bone Foreign Body: A Rare Case Report

“…When the traumatic injury is a cause and history of obstructive sialadenitis so diagnosis is relatively easy [6]. However, in cases without traumatic injury, it is obscure whether the cause is retrograde migration for these 4 reasons: (1) there is almost steady salivary flow; (2) the orifice of duct is mobile and can twist in al (3) the diameter of the duct at the orifice is miniature; and (4) in most submandibular glands, there is a sphincter-like system in the first 3 cm of Wharton's duct that prevents the retrograde migration of substances [17,21,22,23].…”

However, in cases without traumatic injury, it is obscure whether the cause is retrograde migration for these 4 reasons: (1) there is almost steady salivary flow; (2) the orifice of duct is mobile and can twist in all directions;…”

“…Findings support the possibility that some sialoliths might result from retrograde migration of a fishbone through the orifice of Wharton's duct. Fish bones are one of the most common foreign bodies found in the pharynx and esophagus, but they are very rarely found in the salivary gland or the duct [4][5][6][7][8][9][10]13,14,24,25]. In previous studies, the incidence of a fishbone encompassed by a sialolith ranged from 2.8% (12/423) to 4.4% (5/114) of patients with sialoliths of the submandibular gland [6,8,26].…”

“…Obstructive sialadenitis of the submandibular gland is usually due to sialoliths, but foreign body-associated sialadenitis is not often and rare in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The mechanism of foreign-body entry is generally traumatic [4][5][6]15], thus reports of a foreign body entering the salivary gland intraorally through Wharton's or Stensen's duct are not common and usual. [4,5,7,16].…”

“…[4,5,7,16]. Foreign body-induced sialoliths are even rarer [6,8,9,17,18]. As we know, sialoendoscopy is one of minimally invasive procedure that has recently been applied for direct diagnosis of pathologic features in the ductal system and removal of sialoliths and foreign bodies in the duct of the salivary gland but it is used for distal of the salivary's duct [4][5][6]12,19].…”
