A Case of Endoscopic Removal of a Parenchymal Sialolith of the Submandibular Gland Under Local Anesthesia

Abstract

Recently, endoscopic removal of sialoliths has been introduced to avoid invasive surgery including submandibular sialoadenectomy. However, endoscopic treatment is commonly performed under general anesthesia in view of the patient’s tolerance and long surgical time. As a minimally invasive surgery, we report here the endoscopic removal of a parenchymal sialolith of the submandibular gland under local anesthesia. A female in her 70s with swelling in the right submandibular gland was admitted to our department for endoscopic removal of a sialolith of the submandibular gland. Computed tomography showed that the right parenchymal sialolith was 3.1×2.8×2.6mm in size. The patient underwent endoscopic removal of the sialolith under local anesthesia as a minimally invasive surgery. The sialolith was completely removed and the surgical time was 35 minutes. The postoperative course was uneventful.
