Calculus at the duct orifice of the submandibular gland in a patient with an edentulous jaw: A case report and literature review

RATIONALE: The intricate and uncontrollable etiology of sialolithiasis compels clinicians to focus solely on disease management, often overlooking the underlying causes of sialolithiasis and neglecting patient education regarding preventive measures. The use of the multidisciplinary Salivary Gland Association questionnaire enables the identification of benign salivary gland lesions and evaluation of patients' quality of life. PATIENT CONCERNS: Wanting to remove foreign body from the bottom of the right lower side of the mouth. DIAGNOSES: Ductal calculus of the right submandibular gland. INTERVENTIONS: We present a case of calculi in the right submandibular duct orifice of a 66-year-old male patient with an edentulous jaw. The patient reported discovering foreign bodies on the floor of the mouth persisting for 1 week without experiencing any discomfort and requested treatment for these foreign bodies. Subsequently, the patient underwent a transoral sialolith extraction. OUTCOMES: The patient experienced no postoperative discomfort, and the submandibular gland texture and salivary secretion function were normal after 8 weeks of follow-up. The patient's Multidisciplinary Salivary Gland Society (MSGS)/Q10 score decreased significantly 6 months after surgery. LESSONS: Sialolithiasis may remain asymptomatic throughout its course, and early intervention and treatment can effectively prevent severe complications. The MSGS/Q10 questionnaire may be a valuable tool.
