We present a case of submandibular duct calculi diagnosed using transoral sonography. Sonography is the first-line imaging modality of salivary gland calculi. However, it is performed via a transcutaneous approach, which is limited in identifying small salivary duct calculi. Using an intraoral transducer, transoral sonography can visualize the submandibular duct and detect the presence of small calculi, thus overcoming the limitations of transcutaneous sonography.
我们报告一例经口超声诊断的下颌下腺导管结石病例。超声检查是唾液腺结石的一线成像方式。然而，它是通过经皮途径进行的，在识别小唾液腺导管结石方面存在局限性。使用口内探头，经口超声可以显示下颌下腺导管并检测小结石的存在，从而克服了经皮超声的局限性。
