Wharton’S Duct

ABSTRACTSialoliths are the most common diseases of the salivary glands. They may occur in any of the salivary gland ducts but are most common in Wharton’s duct and the submandibular gland. This report presents clinical and radiographical signs of two unusually large sialoliths. There were painless swellings on the floor of the mouth in both cases. Radiographical examination revealed large irregular radioopaque mass superimposed right canine and premolar areas. After the lesions were removed, histopathological examination was performed and lesions were diagnosed as sialoliths. (Eur J Dent 2009;3:135-139)

Autotransplantation of the submandibular gland is effective for severe keratoconjunctivitis sicca. However, most transplants show decreased secretion shortly after the operation, which leads to obstruction of Wharton’s duct. The hypothesis that decreased catecholamine release due to denervation contributes to hypofunction in the early phase was tested in transplanted glands in rabbits. We found that salivary flow, expression of β1- and β2-adrenoceptor, and the maximum binding capacity were markedly decreased in the transplanted glands. Isoproterenol significantly reversed the decreased secretion, enhanced the expressions of β1- and β2-adrenoceptor, and ameliorated the atrophy of acinar cells. The contents of cAMP and phospho-ERK 1/2 were increased after isoproterenol treatment. These results indicate that lack of β-adrenoceptor stimulation is involved in early dysfunction of the transplanted gland. Isoproterenol treatment moderates structural injury and improves secretory function in the transplanted submandibular gland through up-regulating β1- and β2-adrenoceptor expression and post-receptor signal transduction.

Submandibular Gland Excision

Treatment of salivary stones includes both surgical and non-surgical techniques. Surgical approaches range from excision of the sialolith, for those near the duct orifice, to removal of the affected salivary gland and its associated duct, for stones near the hilum of the gland. We present a case of two sialoliths triggering an acute infection in a residual Wharton's duct, 12 years after the removal of the associated submandibular gland. Excision of the sialoliths and treatment of the infected duct via sialodochoplasty was successfully performed in this patient. If the Wharton's duct is not removed with the associated submandibular gland, the potential for infection and continuous growth of dormant calcifications exists. We also address the aetiology, pathogenesis, and management of patients with sialolithiasis in the absence of a major salivary gland.

Wharton’S Duct

Introduction: The submandibular gland is located bilaterally in the submandibular triangle. The main submandibular duct or Wharton’s duct, runs with lingual nerve to open in the sublingual papilla at the side of frenulum of the tongue. The aim of this study was to demonstrate the unusual variations of accessory submandibular duct in comparison with main submandibular salivary gland duct. Material & Methods: Nineteen cadavers were dissected to study the submandibular salivary duct. Results: 15.7% incidence of variations were observed. We found that one submandibular region was having unusual path of accessory duct, it emerged from superficial part of the gland and crossed the superficial surface of mylohyoid muscle and bifurcated into two branches. These bifurcated branches of duct pierced the mylohyoid muscle to pass between mylohyoid and hyoglossus muscle. One branch of bifurcated accessory duct opened through papilla in the floor of the mouth behind the lower incisor tooth and second branch of the bifurcated duct anastomosed with the main duct (Wharton’s duct) to open in sublingual papilla. Wharton’s duct of this side followed its normal path to open in the sublingual papilla. Two specimens of submandibular region was observed with duplication of submandibular duct in each submandibular gland. One was main duct and second was accessory duct. Both ducts emerged separately from the deep part of submandibular gland and ended independently into sublingual papilla. Conclusion: Reporting of these variations are important for diagnostic imaging, anatomical teaching and to help surgeons while operating in this region.

Structural Injury

Autotransplantation of the submandibular gland is a potential treatment for severe kerato-conjunctivitis sicca. However, one of the major barriers to this procedure is that secretions from the transplanted gland decrease shortly after the operation, which may lead to obstruction of Wharton’s duct, or even to transplantation failure. Using a rabbit model, we investigated whether phenylephrine could improve the secretion from the transplanted gland. We found that phenylephrine treatment significantly reversed the decrease in salivary secretion after transplantation, enhanced the expressions of α1A-, α1B-, and α1D-adrenoceptor mRNA, and ameliorated atrophy of acinar cells. Furthermore, phenylephrine also induced translocation of aquaporin-5 from the cytoplasm to the apical membrane, and increased the levels of phospho-ERK1/2, ERK1/2, phospho-PKCζ, and PKCζ in the transplanted gland. These results indicate that phenylephrine treatment moderates structural injury and improves secretory function in the transplanted submandibular gland through promoting α1-adrenoceptor expression and post-receptor signal transduction.

Wharton’S Duct

Sialolithiasis is the common disease of salivary glands. The majority of sialoliths occur in the submandibular gland or the Wharton’s duct. The length of sialolith usually measures from 1 to <10 mm. This article reported a case presenting with sialoliths of a 22mm×15mm in size in the Wharton's duct, which were surgically removed without any complications, and subsequently discusses occurrence factors, signs and symptoms, diagnostic methods and the treatment of sialolithiasis.
