“…We diagnosed our case of accessory submandibular gland and duct on the basis of the presence of two ducts originating from the same orifice, the lower one leading to glandular tissue. Our case is similar to that reported by Towers, 1 which this author labelled as duplication of the submandibular duct.…”

Magnetic resonance identification of an accessory submandibular duct and gland: an unusual variant J Laryngol Otol 2007;121:E18 Dear Sirs Gadodia and colleagues 1 present excellent radiological images of Bartholin's duct and the greater sublingual gland, which they have interpreted as an accessory submandibular duct and gland. This error is understandable because the detailed anatomy of the sublingual gland is much more complex than is generally appreciated. Leppi 2 discovered that the sublingual gland consists of a constant, lesser sublingual gland and a greater sublingual gland. The latter is posterior to the lesser sublingual gland in the paralingual space and was only found in 10 out of 28 people, and usually only unilaterally. Bartholin's duct runs from the greater sublingual gland to either join or open independently of Wharton's duct. The lesser sublingual gland consists of between eight to 30 small glands, from every one of which a duct of Rivinus passes to open independently on the sublingual fold. Thus, the sialograms in the paper by Gadodia and colleagues 1 show Bartholin's duct running parallel to the dilated Wharton's duct, which indicates that these ducts join, and the sublingual gland. The authors mention that there was stasis in Wharton's duct following stimulation by lemon. It would be interesting to know the situation in Bartholin's duct, where stasis would not be expected, particularly as the sublingual gland is a spontaneous secretor and continues to secrete in the absence of stimulation, and also exhibits a great resistance to obstruction.

“…However, extensive review of the literature revealed previous reports of anatomical variations of the submandibular ducts [9][10][11][12][13][14][15][16][17][18]. Pownell et al reported on the aetiology of ductal formation deformities and suggested that anomalies of the duct can result if the developing duct invaginates in 2 places or if premature ventral branching of the duct occurs with duplication Adhesion of endothelium of the dilated duct might divide into a double endocavity.…”

Background: The submandibular gland is the second largest major salivary gland and weighs 7-16 gr. The gland is located in both sides of the face, at the same level of the body of the jaw, in the submandibular triangle, The submandibular duct or Wharton's duct exits anteriorly, coursing deep to the lingual nerve and medial to the sublingual gland, the main excretory duct of the submandibular gland, whose diameter is of 2 to 3 mm and approximately 4-5 cm long. It empties lateral to the lingual frenulum through a papilla in the floor of the mouth behind the lower incisor tooth. The purpose of this study was to determine the morphologic features and describe an unusual anatomical variation of the path of the submandibular duct. Methods and Findings:A total of 17 cadavers were used for this study in the Morphology Laboratory at the University of Pamplona. In a cadaver were findings: The excretory duct of the left submandibular gland had an external location that ascends and crosses vertically off the body of the mandible, in its termination it is divided in four ducts that had separate openings into the oral cavity upon a small papillae independent, opposites to the first and second lower molar Crown. Conclusions:Awareness of potential variations of the excretory ducts of the salivary glands can aid in the accurate diagnosis and treatment of patients with salivary conditions as well as help surgeons avoid further complications or duct lacerations during surgical procedures.
