case_images: (A) Computed tomography (CT) shows the absence of a right submandibular gland in the patient 1. (B) CT shows 2 irregular high-density masses in the front part of the main submandibular duct in the right mouth floor area of patient 1. (C and D) Stones and suture were taken out during the operation of patient 1.

case_images: In addition, 2 irregular high-density masses with maximum diameters of  1.1 cm and 0.6 cm were visible in the right floor of the mouth anterior to the main SMG duct (Fig. 1A and 1B). In Figure 1, the stones and suture are visible upon cutting the removed duct from patient 1 (Fig. 1C and 1D).
case_images: (A) Computed tomography (CT) shows the absence of a right submandibular gland in the patient 2. (B) CT shows the irregular high-density mass in the front part of the main submandibular duct in the right mouth floor area of patient 2. (C and D) Stones and suture were taken out during the operation of patient 2.
