“…If the gland is functional, periodic follow-up examinations are indicated. An atrophic, fibrotic submandibular gland is of little clinical consequence, and excision may not be necessary, if asymptomatic [26]. In this case report, 2-weeks postoperatively, it was observed that clear saliva was flowing from the orifice of left Wharton's duct.…”

Sialolithiasis accounts for the most common cause of diseases of salivary glands. The majority of sialoliths occur in the submandibular gland or the Wharton's duct. This article discusses review of literature, predisposing factors, signs and symptoms, diagnostic methods and various modalities available for the management of sialolithiasis. This case report presents a case of sialolith of a large size in the left Wharton's duct, which was explored and removed via an intra-oral approach.Keywords Sialolithiasis Á Wharton's duct Á Transoral sialolithotomy Sialolithiasis, also called salivary calculi or stones, is the occurrence of calcareous concretions in the salivary ducts or glands [1]. Sialolithiasis accounts for more than 50% of the diseases of major salivary glands, and is the most common cause of acute and chronic infections of the salivary glands [2]. Review of LiteratureSialolithiasis usually occurs from the third to fifth decade of life, and slightly more often in males (4:3) [3-5], and is rare in children [4, 5]. The reported incidence of sialolithiasis is 80-94% in submandibular duct or gland, 5-18% in parotid gland, and 2% or less in sublingual gland [4].The most common site is submandibular gland and Wharton's duct, probably, as a consequence of mucinous saliva, a tortuous duct, gravity, and the small orifice of the duct [6]. Simultaneous sialolithiasis in more than one salivary gland is rare [2]. Sialolithiasis occurs in the sublingual and minor salivary glands and ducts in the decreasing order of frequency [1]. The right and left glands and ducts are equally affected [3,4], although bilateral occurrence is rare [4]. However, multiple sialoliths in the same duct or gland are common [4]. Submandibular gland sialoliths have been reported to be radiopaque in 80-94.7% of cases [4,7,8].Although the exact cause of sialolithiasis remains unclear, some sialoliths may be related to dehydration, which increases the viscosity of the saliva; reduced food intake, which decreases the demand for saliva [9]; or certain medications that lower the production of saliva, such as anti-histaminics, anti-hypertensives and anti-psychotics, and antidepressants [9,10]. The lack of saliva can also be caused by several circumstances, including aging, Sjogren's syndrome, and radiotherapy of the head and neck region [10].The predisposing factors are: alkaline pH of saliva, increased calcium concentration in the saliva of submandibular gland, and the tortuous course of the duct [4]. Some other factors inherent to the submandibular gland are: longer and larger caliber of the duct, flow against gravity, slower flow rates and higher mucin content of the saliva [11]. The formation of sialolith is not related to any systemic derangement in calcium or phosphate metabolism [12].A study conducted by Sheman and McGurk [13] indicated no link between water hardness and sialolithiasis or sialadenitis, suggesting that high calcium intake might not lead to sialolithiasis. Patients with gout and patients on diuretic therapy may be predi...

“…The reported incidence of radiolucent submandibular sialoliths is 20-43% [8]. The other advanced imaging modalities also used include: sialography [22], xeroradiography (especially for radiolucent sialoliths) [3], ultrasonography [1], scintigraphy [26] and computerized tomography and magnetic resonance imaging [27].…”

“…Minimally invasive techniques have now gained precedence owing to reduced morbidity, retaining a functional gland after removal of calculi and the procedure being day-care and performed under local anaesthesia [7,8]. More than 70% of calculi can be retrieved using these techniques, and 2% unsuccessful cases will require a sialadenectomy [8].…”

Sialolithiasis is the most common cause of inflammatory disease of large salivary glands and occurs in about 1.2 % of the population. It most often occurs in the submandibular gland (87 %); followed by the parotid gland -(10 %) and the sublingual gland -(3 %). The introduction of minimally invasive surgical procedures has significantly reduced the rate of major salivary gland removal due to sialolithiasis. Sialoendoscopy is the method of choice with a high rate of success and gland preservation in small and medium stones. The combined transoral and endoscopic approach is indicated for large stones in the submandibular gland. In order to stabilise the duct and prevent the formation of a secondary stenosis, it is appropriate to insert a stent. Long term follow up shows that this dual approach surgery can be performed with a high rate of success.

“…Various research studies using scintigraphic or histological method proved that the removal of the salivary stone hardly causes irreversible damage to gland tissues regardless of chronic inflammation caused by the salivary stone 3234 . According to the research of Yoshimura et al 33 , after removing the salivary stone, 78% of the function of gland tissues was recovered. Marchal et al 34 reported that, after analyzing histologically, more than half of the cases showed normal shape.…”

(J Korean Assoc Oral Maxillofac Surg 2012;38:44-9) Introduction: Sialolithes are initiated by localized deposition of calcified material in the salivary glands. And that may even cause various symptom especially swelling and pain. This study purposes to collect statistical data of sialolithiasis for clinical analysis. Materials and Methods: Among forty seven patients who have visited Seoul National University Dental Hospital during 2004-2009, patients' age, sex, location and size of stone, radiodensity of stone, symptom, surgical procedure were investigated. Statistical correlation between size, location, symptom was evaluated. Chemical composition was analyzed for 3 sialolithes. Results: The average age was 41.4 years. Sialolithiasis had slight female predilection (57.4%). Most cases occurred in the submandibular glands (91.5%). And most cases had radiopaque features (95.8%). The average size was 7.17 mm. The most frequent location of the stones were the duct orifice and the submandibular gland hilum (16 cases in each), followed by the middle part of the duct (n=8), the intraglandular area (n=4), and the proximal part of the duct (n=3). Eleven cases were asymptomatic. Thirty six cases had complaints of pain, swelling, hardness, and decrease in saliva flow (multiple symptoms). Various methods of surgery was performed. Two cases were self-removed. Thirty seven cases underwent pro cedure involving stone removal alone. Six cases underwent gland extirpation, and two cases underwent ductoplasty. Conclusion: There was no statistical correlation between size, location, and symptoms. Sialolith was composed of Ca (58.5-69.3%), P (30.7-35.7%), organic material, and trace inorganic material.
