Most sublingual cysts are easily diagnosed: a very soft, pale blue swelling at the floor of the mouth, with stretched egg-white fluid aspirated by puncture. This egg-white fluid, originally normal saliva, is not drained properly and accumulates in the area, creating a “cyst-like” appearance. Surgical removal of the sublingual gland to cut off the source is the traditional classical method of treating sublingual cysts. Removal of the sublingual gland usually requires general anesthesia and may damage adjacent structures during surgery, resulting in postoperative obstructive submandibular adenitis and hemianesthesia of the tongue. If the wound bleeds after surgery, urgent reoperation may be required to stop the bleeding. A simple treatment, instead of removing the sublingual gland, is to re-establish the passage for salivary overflow and divert the accumulated saliva to allow the cyst to subside. How is the channel established? — Several sutures are threaded through the cyst. There is no need for hospitalization, no need for general anesthesia, no intraoperative pain, short operation time, and no serious complications. In some patients, several repeat treatments may be required. The sutures are threaded and need to remain in the area of the lesion for about a month. There may be slight discomfort during this time, but it usually does not interfere with normal eating or resting. Even if the treatment is ultimately unsuccessful, the subungual gland can still be removed using traditional surgical methods without aggravation or delay in treatment. It is important to remind that whether the swelling in the floor of the mouth area is a sublingual gland cyst and whether it is possible to take simple treatment or surgical removal of the sublingual gland, it is important to listen to the explanation of the professional doctor after examination and judgment.
